Opel Legend Turns 50: A Fish Called Manta

• From marine researchers and designers: how Opel Manta got its logo
• On the Baltic Sea coast: world premiere at appropriate location
• Big fish: Opel Manta A and B produced over one million times

It belongs to the Mobula genus (rays, stingrays) –  Opel Manta, probably the most fishy representative in a long line of Opel classics. This year, the coupé with the ray as logo is celebrating its 50th birthday. The Manta’s range extends from the German Baltic Sea to the American Pacific coast. Opel chief designer, George Gallion, on a secret mission, first discovered the ray from Rüsselsheim.

On a Saturday morning in 1969, Gallion boarded a plane to Paris. American designer who worked at Opel had agreed to meet the team of French marine researcher, Jacques Cousteau.

“We had chosen the name ‘Manta’”, said Gallion, 51 years after his Paris mission. “At that time, animal names matched the zeitgeist, the Ford Mustang and Corvette Stingray were very successful in the United States. Our Manta was also such a ‘pony car’. Now we had ten days to design a logo, but we couldn't find any suitable templates for it”,

So Gallion got on the plane and looked at Cousteau's images in the French capital. For hours. Until finally there was a shot in which a gigantic manta ray filmed from below against the bright surface. Bingo. That was it. The big catch. Opel Manta had found its identity and from then on got the iconic chrome-plated emblem attached to the front fenders.

Opel Manta made its debut at Timmendorfer Strand

Sporty Opel Manta made its debut in September 1970. Appropriately enough, the presentation took place at Timmendorfer Strand on the German Baltic Sea coast. For Opel, the Manta was a step into new territory. “Instead of making an existing model obsolete, the car we are presenting today is an addition to our range and meets a new demand from the market,” said the press release at the time.

Opel Manta was new, smart and sporty, and perfectly timed. Attractive coupés that could accommodate four were highly popular. Individuality was in fashion, the Manta’s shape and lines were just what the market was looking for. In the first full year of sales, Opel moved 56,200 units of the Manta out of the showrooms; 498,553 left the factory in total. Opel Ascona shared the platform, suspension and engines. Most powerful engine in Opel Manta was the four-cylinder 1.9 S with 90 hp, also used by the Opel Rekord.

Opel  Manta range began with the 60 hp 1.2 in 1972, followed in November of the same year by the luxuriously equipped Manta Berlinetta. Standard equipment included sports steering wheel, heated rear window, halogen headlamps, electric windscreen washers and vinyl roof. Five years of production were enriched by numerous special model variants – “Holiday”, “Plus”, “Swinger” and “Summer Bazar” combined up-market specifications with modest prices. Opel Manta GT/E, powered by a 105 hp, 1.9-litre engine with Bosch L Jetronic fuel injection, appeared in 1974. The trend towards matt instead of chrome trim continued with the Manta GT/E. The last special model arrived in 1975, shortly before the debut of the Opel Manta B. GT/E-based “Black Magic” was all black with orange stripes on its flanks.

Sequel followed just five years after the premiere

Already in 1975, the next Opel Manta made its debut with the B version. German brand had two variants in the range: the coupé with notchback and the 1978 Combi-Coupé CC with hatchback and large tailgate. Its long-lasting popularity ensures that the Opel Manta B has a special role in the company's 120-year-plus automotive history. No other model remained unchanged on the market longer than the Opel Manta B – presented in autumn 1975, second generation Opel Manta rolled 557,940 times off the assembly line until 1988.

As with its predecessors, Opel Manta B shared the platform, suspension and powertrain with the Ascona. Range of four-cylinder engines included 14 versions with displacements between 1.2 and 2.4 litres over the entire production period. Power outputs were between 55 and 144hp.

New models and engines constantly complemented and extended the series and kept it young. Well-known abbreviations and affixes included SR, Berlinetta, GT, GT/J and GT/E. In 1979, newly developed OHC (overhead camshaft) engines replaced some of the older ones with side camshafts. Top GT/E developed 105 and 110hp with the larger 2.0-litre engine and was renamed GSi in 1984.

Rarest and most powerful Opel Manta B was the 400, presented at the Geneva Motor Show in 1981. Opel Manta 400, which got its name from the 400 units needed for group 4 motor sport homologation, featured a 2.4-litre DOHC four-cylinder engine (double overhead camshafts) with four-valve technology and 144 hp. With Opel Manta 400, Guy Colsoul and Alain Lopes won the two-wheel drive class of the 1984 Paris-Dakar Rally, finishing fourth overall behind three four-wheel drive vehicles.

Last two versions of the Opel Manta B were the GSi top model and the GSi Exclusiv produced in small numbers by the tuner Irmscher. In total, more than one million examples of the Manta A and B rolled off the assembly line. A big fish indeed.
