!NEW! Ready: New Generation Whisper Diesels for Opel Mokka and Opel Insignia

• More power and torque combined with outstanding consumption and noise levels
• Successful Opel Mokka available with 100 kW/136 hp whisper diesel from euro 24,685
• Opel flagship Insignia 2.0 CDTI with 125 kW/170 hp available from euro 29,895 

New generation Diesel: Opel Insignia and Mokka SUV now with more power and torque combined with outstanding consumption and noise levels.

Extremely quiet, high power, high torque all combined with low consumption and emissions – these are the key elements of the new generation Opel diesels for Mokka and Insignia. The successful models can now be ordered with the new high-tech four-cylinder engines. The 100 kW/136 hp 1.6 CDTI in the Mokka will deliver a lot of driving fun for an entry-level price of euro 24,685. The Insignia sedan will be available with a 125 kW/170 hp two-liter turbo from euro 29,895 (RRP including VAT in Germany). The smooth and refined engines are another important step in the roll-out of Opel’s new powertrain portfolio and set standards in efficiency and environmental friendliness. Their emissions already meet the Euro 6 standards that will be compulsory from September and they are therefore almost as clean as comparable gasoline engines.

Whisper diesel: 1.6 CDTI for Opel Mokka, 2.0 CDTI for flagship Insignia

The Opel Mokka can currently boast the fastest growth on the European car market. The modern chassis and propulsion technologies are obviously key to the success of the sub-compact SUV. The latest development is the new all-aluminum four-cylinder engine, which will replace the 1.7 CDTI. The new high-tech engine gives more power and torque – up six hp and 20 Nm, respectively – from a smaller displacement, as well as significantly lower fuel consumption.

All-New Opel ECOTEC 1.6 CDTI

The lively 1.6 CDTI in the 100 kW/136 hp version reaches 85 hp per liter – unrivalled in its displacement class – and delivers torque of 320 Nm. Acceleration and elasticity figures promise lots of driving fun: the Mokka 1.6 CDTI accelerates from zero to 100 km/h in 9.9 seconds, and makes the transition from 80 to 120 km/h in fifth gear in just 9.9 seconds. Maximum speed is 191 km/h. The whisper diesel is also extremely economical and kinder to the environment: with Opel’s precise six-speed manual transmission and standard Start/Stop system, the 1.6 CDTI Mokka consumes just 4.1 l/100 km over the combined cycle while emitting only 109 g/km CO2. This is almost 0.5 l/100 km less fuel and 11 g/km less CO2 than the predecessor 1.7 liter version. This new diesel engine complies with the stringent Euro 6 emissions standard, making it almost as clean as a comparable gasoline unit.

The same can also be said for the extremely quiet two-liter turbo diesel in the Insignia. Extracting as much energy from as little fuel as possible is key to both power and frugality, and with an exceptional specific output of 87 hp per liter – a slightly higher power density as Opel’s new-generation 2.0 CDTI – this engine is big on fun-to-drive but small in its impact on customers’ wallets. Impressive torque of 400 Nm is available from 1,750 to 2,500 rpm, and maximum power of 125 kW/170 hp is accessed at just 3,750 rpm. The new powerhouse boasts around four percent more power and 14 percent more torque while maintaining exactly the same consumption as it predecessor and meeting Euro 6 emission standards. The Insignia with the new engine reaches a maximum speed of 225 km/h – an increase of 5 km/h. The sedan accelerates from 0 to 100 km/h in just 9.0 seconds – almost half a second quicker than its predecessor.

Pure high-tech: For strong performance and small ecological footprint

Two of the main contributors to the strong and environmentally friendly performance of both engines are the VGT (variable geometry turbine) turbocharger and the high-pressure, common-rail fuel injection system. Injectors capable of supplying fuel at 2,000 bar and of up to 10 injection pulses per cylinder cycle ensure high power, improved fuel atomization and efficient mixing with the air intake charge. The VGT in the Insignia features an electrical actuator for the variable aspect turbine, giving a 20 percent faster boost response than a vacuum actuator. Thus guaranteeing even more diesel fun.

Drivers will be able to enjoy the new engines without any regrets because Opel’s new generation whisper diesels deliver outstanding emission levels comparable to those of a gasoline engine. The big diesel weakness, the emission of nitrogen oxides, is history. The 1.6 CDTI in the Mokka uses a Lean NOx Trap (LNT), an exhaust after-treatment system upstream of the diesel particulate filter that captures and removes nitrogen oxides (NOx) from the exhaust gases without the use of additives.

The Insignia comes with Opel’s BlueInjection selective catalytic reduction (SCR) system, which removes nitrogen oxide from the engine’s exhaust gases. Tiny quantities of AdBlue®, a harmless fluid consisting of urea and water, are injected into the exhaust gas flow ahead of the SCR catalyst and downstream of the Diesel Particulate Filter (DPF). The solution is immediately converted into ammonia (NH3), which is absorbed by the SCR catalyst. Nitrogen oxide in the passing exhaust gas is then selectively reduced to harmless nitrogen and water vapor in a chemical reaction with the ammonia.

Smooth running: Diesel power with turbine-like refinement

Apart from increasing performance and efficiency, the improvement of running smoothness was a key requirement for the new engines right from the outset of their design. The engineers implemented several measures during construction and fine-tuning to reduce the noise levels and vibrations of the engine thus improving refinement. Architectural improvements focused on two main noise-emitting areas: the top and bottom of the engine and ranged from a decoupled, cam cover on the aluminum cylinder head over a newly designed oil sump to a new balancer shaft module for the two-liter diesel.

Opel ECOTEC 2.0 CDTI: Impressive torque of 400 Nm is available from 1,750 to 2,500 rpm, and maximum power of 125 kW/170 hp is accessed at just 3,750 rpm.

The result: The new 2.0 CDTI can boast reduced noise levels in every rpm range compared to its predecessor and is five decibels quieter when idling.

And the latest generation 1.6 CDTI previously known from the Opel Astra and Meriva MPV has not been nicknamed “whisper diesel” for nothing.

Opel ECOTEC 1.6 CDTI: With the new 100 kW/136 hp Turbo diesel, Mokka SUV boasts a fuel consumption of only 4.1 liters per 100 kilometers over the combined cycle, which is equivalent to a CO2 emission of 109 grams per kilometer.

The all-new 1.6 CDTI Opel Mokka is available with front-wheel drive and six-speed manual or automatic gearbox. The all-wheel drive (AWD) comes with a six-speed manual gearbox. Opel Insignia sedan, liftback and Sports Tourer with the new two-liter turbo diesel are available with a six-speed gearbox and front or four-wheel drive.
