Slated to make its world premiere at the Mondial de l'Automobile 2014 next month, the new oil burner boasts with 'whisper diesel' credentials, 136 ponies and a hefty 320 Nm of torque. In comparison to the outgoing 1.7-liter turbo diesel mill, the new powerplant is up 6 horsepower and 20 Nm of torque, but a tad more fuel efficient and refined.
Being a turbo diesel, the new powerhouse promises to drink just 4.1 liters of fuel every 100 kilometers (57.3 US mpg or 68.8 UK mpg) on the NEDC cycle, with CO2 emissions of just 109 grams per kilometer. Compared to the aging 1.7 turbo diesel engine, the 1.6 CDTI sips 0.5 liters less fuel per 100 kilometers.

Starting from the first quarter of 2015, the 1.6 CDTI will be added to the engine range of the Opel Mokka B-segment crossover. What about acceleration and elasticity figures? Well, the Opel Mokka 1.6 CDTI gets to 100 km/h (62 mph) in 9.9 seconds and sprints from 80 to 120 km/h in 5th gear in 9.9 secs as well. Maximum speed sits at 191 km/h (118 mph).

Less displacement isn't necessarily a bad thing

Coming as standard with a start/stop system and a six-speed manual transmission, the 1.6 turbo diesel engine complies with the EU6 emissions standard, making it as clean as a comparable gasoline unit. If you want to get a bit more technical, you might be interested to find out that the engine block of this oil burner isn't made of cast iron, but aluminum. Even the crankshaft bedplate and cylinder head are also constructed from aluminum in order to save weight.

The turbocharger uses variable turbine geometry to keep the power delivery nice and sweet, while the 'whisper diesel' end of the bit is credited to a high-pressure common-rail fuel injection system. Opel says that injectors are capable to supply diesel fuel at 2,000 bar of pressure and up to 10 injections per cylinder cycle for improved fuel atomization.

A Lean NOx Trap (LNT) exhaust after-treatment system is also there to capture and reduce nitrogen oxides from exhaust gases. Last but not least, those that want more comfort from the Mokka will be happy to find out the new 1.6 mill can be coupled to an optional six-speed automatic transmission.
