Opel has announced the 1.6 CDI and 2.0 CDTI "whisper diesels" are now available for the Mokka and Insignia, respectively.

Revealed last September, these newly developed Euro 6 turbodiesel engines from Opel promise to provide low fuel consumption and emissions as well as a smooth & refined operation. Opel says these new motors are very quiet and quicker than their predecessors and are "as clean as comparable gasoline engines."

The 1.6 CDTI offered in the Mokka serves as a replacement for the 1.7 CDTI and despite the smaller displacement it adds 6 HP & 20 Nm for a total of 136 HP (100 kW) and 320 Nm (236 lb-ft) of torque. It's enough to grant the subcompact crossover with a 0-62 mph (0-100 km/h) run in 9.9 seconds before topping out at 118 mph (191 km/h). Mated to a six-speed manual gearbox and a stop/start system, the Mokka 1.6 CDTI is 0.5 liters / 100 km more economical than its predecessor and also has 11 g/km fewer CO2 emissions. It now consumes just 4.1 liters / 100 km (57.3 mpg US / 68.8 mpg UK) with corresponding emissions of 109 g/km.

As for the Insignia 2.0 CDTI, this one gets a two-liter turbodiesel engine outputting 170 HP (125 kW) at 3,750 rpm and 400 Nm (295 lb-ft) of torque available in the 1,750 to 2,500 rpm range. This means it has 4 percent more horsepower and 14 percent more torque than the old engine while keeping the same fuel economy numbers and Euro 6 compliance. The 0-62 mph (0-100 km/h) sprint for the sedan now takes 9 seconds (almost 0.5s quicker) and it will top out at 225 km/h (up by 5 km/h).

More details about both engines can be found in the attached press release.
