Large Opel Models Delight at the Bodensee Klassik 2017

• Spectators applaud the historic Opel Kapitän, Admiral and Diplomat fleet
• Opel VP Sales & Aftersales Peter Küspert in the Opel Diplomat B V8 presidential limousine
• Actors Roman Knižka and Tim Wilde shine as approachable Opel celebrities
• Brand ambassador Joachim Winkelhock celebrated in rare Opel Kapitän A V8

Line-up: All-New Opel Insignia Grand Sport with its legendary ancestors, a 1976 Opel Diplomat, a 1956 Opel Kapitän and a 1990 Lotus Omega.

The 6^th edition of the Bodensee Klassik took place on picturesque circular routes starting in Bregenz and the competitors crossed over the borders between Germany, Switzerland and Austria. The spectators once again got their money’s worth and could enjoy the large Opel flagships ranging from the Kapitän to the Admiral and Diplomat right up the new Insignia Grand Sport.

The Opel fleet was led by a Diplomat B V8 with an extended wheelbase. It was used as one of the presidential limousines when US President Gerald Ford visited Germany. Opel Vice President Sales & Aftersales Peter Küspert was behind the wheel of the Diplomat during the Bodensee Klassik. “This is a piece of living automotive history. Our Diplomat is a really impressive car and the V8 engine ticks over beautifully. The spectators were gripped and listened attentively – and so did I,” said Küspert, who was joined in the car by Roman Knižka. Elsewhere, fellow actor Tim Wilde shared the cockpit of the rare Opel Kapitän V8 – this engine was normally reserved for the Opel Admiral and Diplomat and only 130 Kapitän V8s were produced – with Opel brand ambassador and racing legend Joachim Winkelhock.

The route of the 6^th Bodensee Klassik spanned around 600 stunning and challenging kilometers on scenic side roads through Germany, Austria and Switzerland. Each stage started and finished in Bregenz, state capital of the Austrian federal province of Vorarlberg. Day one saw the participants drive to Bad Waldsee in Upper Swabia. On day two, the rally headed to Kempten and back. And on the third and final day the 180 classic cars drove through beautiful Vorarlberg and the charming Appenzell.

!NEW! Eight Decades of Big Opel Cars: Flagship Parade at Techno Classica

Opel flagships at Techno Classica: From Opel Admiral to All-New Opel Insignia Grand Sport

.

Opel’s big boys have got their sights firmly set on the 29^th Techno Classica in Essen, where Opel Classic and the enthusiasts from Alt Opel IG (vintage Opel owners club) will exhibit big cars from Rüsselsheim from both past and present. “The Opel Flagships” is this year’s motto and the cars will be on show at the stand with a total surface area of 400 square meters in Hall 2. The legendary pre-WWII Admiral that celebrated its premiere in 1937 is the spearhead of the Opel fleet. It is hard to imagine that the wonderful art déco style chassis is already 80 years old when you see it up close. The journey through time continues with the two millionth Opel produced, a 1956 Kapitän. Typical representatives of the KAD models such as a 1968 Diplomat A and a 1970 Opel Admiral – two true street cruisers – are also present. The 1978 Senator A is a typical design from the somewhat more matter-of-fact 1970s, whereas the new Opel flagship, the Insignia Grand Sport, demonstrates Opel’s current design philosophy of “Sculptural artistry meets German precision”.

Eight decades of “Big Opels”: Legendary 1937 Opel Admiral and All-New Opel Insignia Grand Sport.

From 1937 to 2017: From the Opel Admiral to the new Opel Insignia Grand Sport

The large Opel cars can look forward to enjoying the limelight at the Techno Classica in Essen – just like they did in Rüsselsheim 80 years ago. To mark the 75^th anniversary of the Adam Opel AG on February 17, 1937 the company presented two visionary newcomers: The Admiral and the Super 6. Both cars were equipped with modern engine technology. Inline sixes with displacements of 3.6 and 2.5 liters and 75 hp and 55 hp respectively. The Admiral was the first member in a line of luxurious models that continued for 40 years. The Super 6 paved the way for the popular 1938 Kapitän.

Ten years later the first post-WWII Kapitän left the plant and the economic miracle saw it rise meteorically. The Opel Kapitän was one of the bestselling six cylinders in Germany and became an international bestseller with 60 percent of all Kapitäns being exported. The Kapitän built on November 9, 1956, and on display in Essen plays a special part in the success story. As the two millionth Opel ever built, its roof was painted in gold and it also sports 24-carat gold plated decorative elements. Opel was the first German and European carmaker to surpass the two-million mark.

The Opel upper class was completely overhauled in 1964. The “Big Three” were called Kapitän, Admiral and Diplomat and for the first time in its history Opel offered V8 engines. The ranking order in the premium class was determined by equipment and engine size. The Kapitän and Admiral initially came with Opel’s proven 100 hp, 2.6 liter six-cylinder engine, whereas the Diplomat’s engine was sourced from the United States. The flagship of the KAD series featured a 4.6 liter V8 with 190 hp. As of the spring of 1965 both the Kapitän and the Admiral could optionally be ordered with the 4.6 liter V8 engine and automatic transmission used in the Diplomat. To this very day the Kapitän and Admiral V8s are models with a special status: Only 113 units of the Kapitän and 622 units of the Admiral were built.

The members of the second KAD range were completely overhauled from 1969 – and grew in all areas. The Kapitän once again represented the entry-level KAD model. Its 2.8 liter inline six delivered 132 hp. Above it, sat the comfortable Admiral that delivered 145 hp at the 2800 S variant and 165 hp as the Admiral 2800 E. The top-of-the-line engine was the 5.4 liter V8 with 230 hp that came as standard in the Diplomat.

40 years after the Admiral made its debut, the company brought another new big Opel to market. From 1977, the Senator was the spearhead of the model portfolio. The Senator and its coupé sibling the Monza were the first Opel cars with independentl rear suspension and space-saving mini-block coil springs.

Another four decades down the line, eighty years after the Admiral, the time has come for another major debut: The new Opel Insignia Grand Sport will make its first home appearance at the Techno Classica.

The all-new Opel Insignia is in extremely good shape. It has the sporty elegance of a large coupé, its completely new architecture makes it uncompromisingly spacious and truly fun to drive, and it offers exemplary safety and comfort features just as a true flagship should. Not only does the second-generation Insignia impress with its breathtaking lines on the outside and great wellness atmosphere on the inside, it also provides the widest range of intelligent technologies reaching from the trendsetting Opel IntelliLux LED Matrix headlights and the very sophisticated all-wheel drive system with torque vectoring to ultra-modern driver assistance systems and a refined head up display. In addition, the Insignia comes with Opel-typical first-class connectivity with smartphone integration which now offers a new Opel OnStar feature – the Personal Assistant which allows Opel Insignia occupants to book hotel rooms^[1] and search for parking^[2] via an OnStar Advisor. Overall, the new Opel Insignia wows with high agility and driving precision, more space and a superb price-performance ratio that now more than ever make it a contender to be reckoned with, even for premium brand models.

Strong team: Opel Group CEO Dr. Karl-Thomas Neumann will take part in the old-timer rallye “Bodensee Klassik” with his own Diplomat V8 Coupé.

Opel will be present with some very special car when the fourth Bodensee Klassik starts in front of the festival hall in Bregenz, Austria at 14.00 CET on May 7. Opel Group CEO Dr. Karl-Thomas Neumann will also be in the field with his very own Diplomat A V8 Coupé. The list of rarities from Rüsselsheim also includes a further, very rare Diplomat A Coupé with a 5.4-liter V8 engine with 230 hp and equally rare Admiral A and Kapitän A models with eight-cylinder power under the long hood. A Diplomat B and a Kapitän B round off the offer for old-timer fans.

In total, 180 classic cars will take part in the tour taking them through parts of Germany, Austria and Switzerland before reaching the finish in Bregenz on May 9. The Opel CEO is not the only famous face to take to the wheel of one of the cars from Rüsselsheim. TV stars Gesine Cukrowski and Tim Wilde along with Opel Brand Ambassador and racing legend Joachim Winkelhock will also be at the start and complete the Opel-Classic-Team.

The two Diplomat A V8 Coupé are members of an exclusive series consisting of only 347 unit produced by Osnabrück-based body makers Karmann from 1964 onwards. The vehicle identification number of Dr. Karl-Thomas Neumann’s 1967 coupé ends in 347 – clearly identifying it as the last of the exclusive vehicles ever produced.

Interesting course: Opel Group CEO Dr. Karl-Thomas Neumann is looking forward to the rallye with 180 classic cars that will take the field through Germany, Austria and Switzerland.

“I have always been fascinated by the combination of the timelessly elegant coupé body of the Diplomat and the legendary Chevrolet Small Block V8,” said Dr. Karl-Thomas Neumann. “I have been the proud owner of this car for roughly six months now and I am delighted when I get the opportunity to take this icon for a spin.”

Powerful engines: Opel Group CEO Dr. Karl-Thomas Neumann will swap his Insignia OPC with 325 hp for his Diplomat Coupé with 230 PS for the “Bodensee Klassik“.

The KAD models of the first series taking part in the Bodensee Klassik are all powered by various versions of the famous GM V8 engine that celebrated its debut 60 years ago and has been built over 100 million times to date.

Powerful engines: Opel Group CEO Dr. Karl-Thomas Neumann will swap his Insignia OPC with 325 hp for his Diplomat Coupé with 230 PS for the “Bodensee Klassik“.

Neat appearance: The Coupé, built by body specialist Karmann, was based on the Diplomat V8 sedan. The roof was shortened, the front doors extended and a welded steel plate replaced the rear doors.

!NEW! Opel at Techno Classica 2015 – Design as a Brand Value

• Exciting: Ten rare Opel models at vintage car show in Essen
• Innovative: Opel Design Studio first of its kind in Europe
• Ground-breaking: Style icon Experimental GT celebrates 50^th birthday
• Opel design philosophy: “Sculptural artistry meets German precision“ 

Exciting curves. Opel Experimental GT was shown on a slightly slanted platform at the IAA in 1965 to emphasize the two-seater’s dynamic shape.

Opel showcases ten design icons and concept cars at this year’s Techno Classica in Essen (15.-19.04.). The rare models on display range from the Experimental GT, the Diplomat A coupé and the Genève Study to the GTC Concept, and – as an example of Opel’s current design language – the new Corsa. The exhibit demonstrates that exciting design is one of Opel’s core brand values, a message underlined back in 1964, when Opel opened the first design studio owned by a European automaker. It was there that, for the first time, professionally trained designers and modelers – not just design draftsmen and model makers as had been the norm until then – began creating and developing the design of future vehicles. Opel welcomes all the friends of the brand, as well as all those interested in automotive history, to its 650 m2 stand in Hall 2 at Essen.

Originally, the Opel Genéve Concept that made its premiere at the Geneva Motor Show in 1975 was to be powered by a Wankel engine. But the oil crisis in the early 1970s and the engine’s high fuel consumption halted this project. 

The beginnings of automobile design

Opel’s classic collection comprises about 500 cars that embody more than 150 years of the brand’s engineering expertise and embrace various style and design eras. Opel entered the automotive world in 1899 with the Patent Motor Car “System Lutzmann”. While horse-drawn carriages initially served as the starting point for motor car engineering for all manufacturers, immediately after the turn of the century the first approaches to developing specific automotive design characteristics quickly took shape.

Opel engineers were already experimenting with the streamlined shape back then and Opel models from this era often carried the sobriquet “Torpedo”, highlighting their streamlined frontal design. The influence of such design on the shape of future cars was continually growing.

Pioneer of forms. The Design Studio opened in 1964, called N10 internally, set standards for progressive work and quickly turned into a hothouse of creativity for European designers.

In 1964, Rüsselsheim-based Opel was the first European automaker to open its own design center, still called “styling studios” back then. It accommodated the first design organization owned by an automaker outside North America. Just one year after operations began, the first product from the team of Opel designers and modelers made its debut at the Frankfurt Motor Show (IAA) in 1965. Their stunning Opel Experimental GT was the first true concept car from a European automaker. Hardly anyone had expected such a sporty concept car from Opel. And even less expected was that the Rüsselsheim carmaker would bring such a trend-setting vision to the road: in 1968, Opel presented the production-ready GT sports car. Today, the Opel GT is one of the most coveted Opel cars on the classic car market.

Showpiece. Opel Experimental GT was first shown at the IAA in 1965, causing quite a sensation.

The premium-class models from Rüsselsheim’s KAD series are now just as sought after as the Opel GT. Within this model range, the 1965 Diplomat A Coupé occupies a very special place. Like the Experimental GT, it is celebrating its 50th birthday this year and it is a true rarity. Just 347 of these coupés, based on the Diplomat V8 sedan, were built by the Osnabrück coachbuilders Karmann between 1964 and 1968.

The Diplomat A V8 Coupé was not just luxurious, it was one of the fastest grand touring cars of its time

Opel again caused a sensation with another study at the 1969 IAA in Frankfurt. The Opel CD (Coupé Diplomat) thrilled industry experts with its striking, tapered form. The fiberglass body was based on a platform about 30 centimeters shorter than the Diplomat B, together with a wheelbase of 2.5 meters. For demonstration purposes, the glass dome that served as the cabin roof could be folded back as a whole with the windshield. The lattice model displayed at the Techno Classica gives an insight into what was at the time highly innovative technology in the Opel CD.

In 1975 another breath-taking concept study made its debut at the Geneva Motor Show – the aptly named Genève Concept. Designers in Advanced Engineering again created a two-seat sports coupé, this time adopting a mid-engine principle. The shape was even more tapered and streamlined and it was, of course, again fitted with pop-up headlamps.

Opel has continued presenting exciting studies in the small-car segment. At the Geneva Motor Show in 1982, the Corsa Spider, a small two-seat roadster penned by Opel designer Hideo Kodama, was unveiled. It was the forerunner of a completely new small-car range below the Kadett, which debuted in the fall of 1982 as the Corsa. With sales totaling more than 12.4 million units, this model range is today one of the most popular in the small car segment.

With the Opel Insignia study in 2003 and above all with the unveiling of the Opel GTC Concept in 2007, a new design era began at Opel, summed up by the phrase: “Sculptural artistry meets German precision”. Sculpted body surfacing and 3D headlamps are signature styling motifs of the studies created by Chief Designer Mark Adams.

As the latest example of this new design language, the fifth generation Opel Corsa will be displayed at the Rüsselsheim automaker’s stand. The new Corsa shares similarities with the successful lifestyle-oriented Opel ADAM, such as its low grille. And with its wing-shaped headlamps and that signature Opel, ‘blade’ body side, it represents the current, further evolution of Opel design.

• Experts from Opel and Alt Opel vintage car club on site

Techno Classica 2014: Opel celebrates 50th anniversary of KAD models (Kapitän, Admiral and Diplomat).

KAD – this acronym defined Opel‘s upper class range in the 1960s and 1970s. The tradition-rich brand celebrates the anniversary of its ‘Big Three’ at the 26th Techno Classica in Essen (March 26 - 30): Kapitän, Admiral and Diplomat are 50 years old. At the same time, Opel’s current top-of-the-line model builds the bridge to today: the 239 kW/325 hp Insignia OPC is also on display.

Automotive elegance in 1964: Opel’s premium class trio

Kapitän, Admiral and Diplomat: the elegant trio from the 1960s and 1970s at the Opel booth in Hall 2 is sure to turn visitors’ heads. Opel presents eleven versions – some extremely rare – of these classic cars, including one of only four 4-door Diplomat V8 convertibles built as well as a Diplomat V8 with a long wheelbase which was used during the state visit of US President Gerald Ford in July 1975. A black Kapitän from 1969, a former Swiss police car in Bern, is also on exhibit.

“Vintage cars fascinate people more and more. That’s my impression when watching the crowds of visitors,” says Uwe Mertin, Manager Opel Classic Europe. “The vintage car enthusiasts also have a very high level of expert knowledge, the enormous amount of detailed know-how they possess is really impressive.” Especially popular with show visitors is the extremely rare convertible version of the ‘Diplo’. Stylized miniature models of various vehicles are also visitor favorites at the Opel booth. They are in the typical colors of the 1960s and 1970s and give a good idea of colors popular back then that car buyers preferred for their exterior vehicle lacquer.

Performance that impresses: The Big Three from then and today’s most powerful

The full-scale eye-catcher at the Opel booth is the black Insignia OPC Sports Tourer. It shows Opel’s idea of what absolute top performance is, 50 years after the Kapitän, Admiral and Diplomat. The Insignia OPC’s stylish bodywork encapsulates state-of-the-art technology including an enhanced OPC chassis, electronically controlled all-wheel drive system and a 239 kW/325 hp 2.8 V6 Turbo engine with 435 Nm maximum torque. The boldly styled front and rear, with signature OPC design elements such as distinctive saber-tooth detailing at the front and the tailpipe trim integrated in the rear, underline its power and evoke visions of high-speed laps around the Nürburgring. The cabin welcomes OPC drivers with pure motorsport ambience. Recaro performance seats, the OPC gearshift knob and a completely new main instrument panel and center console exude premium flair.

It has become a tradition at the Techno Classica for Opel to present itself together with the Alt Opel IG vintage car club. The biggest Opel fan club in the world has been the Rüsselsheim automaker’s partner at the most important vintage car trade show for years, and once again provides expert discussion partners to answer visitors’ questions about the Opel brand vintage models.

!NEW! Opel’s Big Three: 50th Anniversary for Kapitän, Admiral and Diplomat

• Kapitän, Admiral and Diplomat from 1964 for ‘travelers of class’
• Opel shows premium models at 26^th Techno Classica
• Alt Opel vintage car club continues tradition of Opel booth presence

The “big three” from Opel - KAD model range A, 1964 - 1968

KAD – this acronym is not only familiar to Opel brand enthusiasts. In the 1960s and 70s, Kapitän, Admiral and Diplomat were ‘The Big Three’ vehicles that defined Opel’s upper class range. The tradition-rich brand celebrates the anniversary of its premium class trio at the 26th Techno Classica in Essen (March 26 – 30): Kapitän, Admiral and Diplomat are 50 years old.

The KAD range entered the market in March 1964. With identical bodies in a modern, linear form, the vehicles were distinguished by their equipment and engines. Five years later, they were succeeded by new, B-series models which set standards in their class with the introduction of state-of-the-art chassis technology and even sleeker styling. Opel builds the bridge to today at the Techno Classica with the Insignia Sports Tourer OPC – the top model from Rüsselsheim will also be on display in Essen. As in the past, Opel Classic presents itself together with the Alt Opel IG vintage car club, the biggest Opel fan club in the world. 

Opel Classic presents ten models from two generations

Opel KAD A and B model range 1964 - 1977

The ten KAD vehicles on show at Essen encompass the entire bandwidth of the A and B model series. With a 2.6 liter, six-cylinder engine, the Kapitän A marked Opel’s entrance into the premium class in 1964. Only 113 units of the least common model in the range, the Kapitän with the optional 4.6 liter V8 engine from the Diplomat, were built. In addition, a rare Admiral V8 from the Rüsselsheim Opel Classic collection will be exhibited in Essen. The Diplomat A V8 Coupé also on show was one of the fastest series production cars in Germany in 1965. Retailing at 25,500 Deutschmarks and built by the coachbuilder Karmann, this two-door car was intended for ‘travelers of class’ and had a top speed of 205 km/h thanks to its V8 engine with 5.4 liters displacement and 230 hp.

Representatives of the B-series include a Kapitän and an Admiral, each with a 2.8-liter engine, as well as a Diplomat 2800 E, which was one of the first German six-cylinder cars to feature electronic fuel injection. The KAD exhibition line-up is rounded off by a Diplomat V8 with a 5.4-liter engine, plus two very special variants of the flagship: a Diplomat V8 with a long wheelbase from the Opel Classic collection which was used during the state visit of US President Gerald Ford in July 1975, and a four-door Diplomat 2.8 E Convertible from a private collection which was one of four vehicles modified for representation purposes by Karmann in 1970.

The Big Three from Rüsselsheim

In the spring of 1964, Opel restructured its premium class offer and, after a break of 20 years, again set its sights on buyers of luxury sedans. Kapitän, Admiral and Diplomat were its "Big Three", as the company referred to them in its advertisements. The vehicles adopted linear design inspired by the stylistic role models of Opel’s US parent, General Motors. Designers and critics alike called this type of styling "new objectivity", a marked departure from ornamental, baroque-like bodywork.

The “big three” from Opel: KAD model range A,1964 - 1968

The bodywork of the stretched and progressively designed trio from Rüsselsheim was identical and, with a length of 4.95 meters and a width of 1.90 meters, the body of the Opel premium class contenders reached a new dimension. Opel displayed its greatness!

While the Kapitän, already Germany’s best-selling six-cylinder car, was appearing as a new edition, and the luxuriously equipped Admiral continued the success of the famous pre-war model of the same name, the Diplomat became Opel's new top model. By extending its model range upwards, Opel was the only German manufacturer able to offer customers a complete product portfolio: from the Kadett to the Rekord, Kapitän and Admiral, right up to the Diplomat, every buyer could find a suitable car.

The ranking order in the premium class was determined by equipment and engine size. The Kapitän was the only car in the series with a bench seat up front, giving it a six-seater designation, while the other two models had individual front seats.

The Kapitän and Admiral came with the familiar 100 hp, 2.6 liter, six-cylinder engine, which was fitted with maintenance-free hydraulic tappets for the first time. Another new feature was the fully synchronized, four-speed manual gear shift at the steering wheel. A sporty central shift, or the two-speed automatic transmission, was offered at extra cost. A modern, dual-circuit braking system with front disc brakes came as standard.

The Diplomat’s engine was sourced from the United States: a V8 unit with 4.6 liter displacement and 190 hp powered this flagship of the model series. While the Kapitän and Admiral had a top speed of 155 km/h, the Diplomat achieved 200 km/h and accelerated from zero to 100 km/h in 11 seconds. Luxury, elegance and character were the Diplomat’s distinguishing features: the interior was dominated by deep-pile carpets, plush upholstery and a real-wood veneer dashboard, as well as a band speedometer going up to 250 km/h. A vinyl roof, reclining seats, four electric windows, side mirrors adjustable from the inside, and foot-well lights in the rear passenger compartment were additional exclusive equipment details. Hydraulic steering and braking systems, as well as fog lights, were fitted as standard.

Expansion and upgrading of model portfolio

Just one year after launch, Opel extended the appeal of the KAD model series. From spring 1965, the Kapitän and the Admiral were optionally available with the 4.6 liter V8 engine and the automatic transmission from the Diplomat. An upgraded chassis with reinforced cardan shafts, axles, wheels, tires and brakes was included in the price of 14,740 and 15,950 Deutschmarks respectively for Kapitän and Admiral V8 models, which retained their special status: only 113 Kapitän and 622 Admirals were built.

A short time later the standard versions were upgraded. They received a newly-developed, camshaft-in-head (CIH), six-cylinder engine with 2.8-liter displacement. This quiet, short-stroke, in-line engine shared its CIH design with the four-cylinder engine introduced in 1965 in the Rekord B. As the S version, the new engine delivered 125 hp and reached a top speed of 170 km/h. For model year 1968, a stronger, 140 hp version was also available as an option.

In 1965, Opel gave the Deutsches Museum in Munich a very special Admiral 2.8 S. Converted to a cutaway model in 5,000 hours of work, the exhibit provided insight into the car’s body structure and technology, replacing the Kapitän model on display since 1952. A Diplomat convertible, built by Karmann on a coupé base, and a long, seven-seat version built by the coachbuilder Vogt remained individual showpieces.

For travelers of class

In July 1965, Opel's premium class got an addition in its most elegant form. The Diplomat V8 Coupé rolled off the assembly lines at coachbuilder Karmann in Osnabrück. The most exclusive vehicle in the model range was intended for ‘travelers of class’ according to the advertisements. The price/performance ratio made it one of the top cars in Germany. The 5.4-liter V8 engine, which was also fitted in the Chevrolet Corvette, was reserved for the Coupé up to September 1966. In conjunction with a "Powerglide" two-speed automatic transmission and 427 Nm torque, the 230 hp V8 engine accelerated the four-seat Coupé from zero to 100 km/h in less than 10 seconds, while top speed was 206 km/h.

There was hardly any other car produced in Germany that was faster, and no Opel was more expensive. The Diplomat Coupé cost 25,500 DM, the sedan 17,500, and the lowest price on the price list was 6,980 Deutschmarks for the Opel Rekord. The circle of buyers thus remained small: by 1967 only 304 models of the Diplomat V8 Coupé left the assembly halls of Karmann in Osnabrück. From 1966 the sedan was also optionally available with the 5.4 liter V8.

Up to the model change in 1969, 24,249 units of the Kapitän A were produced, including the variants equipped with the V8 engine. The Admiral and Admiral A V8 were also quite successful, with 55,876 units produced, while production of the exclusive four-door Diplomat totaled 8,508 units.  

The second generation sets technical standards

The “big three” from Opel: KAD model range B, 1969 - 1977

In February 1969 Opel set new technical standards in the premium segment with the new generation KAD models: fundamentally reworked stylistically and technically, they made clear statements in terms of comfort, safety and economy. Kapitän, Admiral and Diplomat had a sophisticated, completely newly developed chassis; body and interior were designed with an emphasis on passive safety. Compared with the predecessor models, the dimensions of the KAD B series were smaller, while the six and eight-cylinder engines were thriftier.

As before, the Kapitän marked the entry level into the new KAD class. Its 2.8 liter, camshaft-in-head, in-line six-cylinder engine delivered 132 hp. Right above this was the comfortably equipped Admiral, which delivered 145 hp in the 2800 S variant and 165 hp in the most powerful Admiral 2800 E version. The electronic Bosch fuel injection was an innovation and was developed especially for the six-cylinder. The modern, smooth-running 165 hp engine was also available in the top Diplomat model. Combined with a three-speed automatic transmission, the 230 hp, 5.4-liter V8 from Chevrolet was reserved for the Diplomat that reached a top speed of 205 km/h. This model distinguished itself with vertical headlamps and rear lights from the Kapitän and Admiral with their horizontally arranged lamps.

Still boasting an impressive appearance, the smooth-surfaced, no-frills body of the "Big Three" was now shorter and slimmer than the previous model series whose design was largely influenced by American tastes. Now the motto was "European with functional design and modern technology."

With the exception of the engines, the new KAD series represented a completely new design. Body structure and interior were characterized by passive safety. The high-tech, coil-sprung De Dion rear axle was the most important innovation on the chassis side. After test drives, car tester icon Fritz B. Busch summarized the qualities of the new premium model as follows: "Opel has outdone itself with this model. Engine, chassis, steering and braking are among the best I have ever come across." 

Just one year after the debut of the second KAD generation, Opel streamlined the model range. In April 1970 the Kapitän was dropped and replaced by the Admiral N. The Diplomat, on the other hand, continued to grow: a long version of the Opel flagship was launched in August 1973 for top managers, ministers and heads of state. The wheelbase grew by 150 millimeters and rear seat passengers enjoyed the full benefit of the additional space.

One model range, many faces

Coachbuilders such as Karmann and Vogt produced other special versions based on the KAD models. Working as a sub-contractor for Karmann, in 1970 the Italian specialist Fissore in Turin converted four Diplomat 2.8 E models to convertible sedans with an open roof and fixed window frame. Until the summer of 1979, the Diplomat convertibles were used as prestigious shuttle service vehicles at major events to transport prominent athletes, actors, politicians and other celebrities.

The Vogt company in Bad Neuenahr took a different approach. As commissioned by Germany's second public-service television broadcaster ZDF, the specialized company converted various Admiral and Diplomat models to fast and spacious camera cars. Thanks to the large trunk lid, even bulky equipment could be easily transported.

Possibly the most attractive Opel Diplomat was launched on the market as a sporty coupé. In 1973 former racing driver Erich Bitter presented the Diplomat CD, modelled on the CD (Coupé Diplomat) study developed by Opel for the IAA car show in 1969. The body of the 2+2-seater was designed by Bitter in collaboration with the Opel Design Center. Built by Baur in Stuttgart, the luxury coupé was based on the Diplomat B.  

After a successful career in the automotive elite, the end came for the "Big Three" of the B series in July 1977 after sales of 11,017 (Kapitän), 31,827 (Admiral) and 18,725 (Diplomat). In 1978 Opel's premium models for travelers of class were replaced by the completely newly designed Senator and Monza models.
