GM-owned Opel and Vauxhall announced that they're preparing to unveil an all-new motor at this year's Mondial de l'Automobile. The new generation CDTI mill displaces 2 liters and is boasting with better figures all-round over the outgoing 2.0 CDTI that's powering the Zafira Tourer MPV and the Insignia.
Whereas the current powerplant churns out 163 horsepower at 4,000 rpm and 350 Nm of torque from 1,750 to 2,500 rpm, the new engine packs 170 horsepower at 3,750 rpm and 400 Nm from 1,750 to 2,500 rpm, just like its predecessor. The figures equate to a 5 percent increase in oomph and a 14 percent hike in torque, but that's not all.

The manufacturer informs that the new motor is Euro 6 compliant thanks to a Selective Catalytic Reduction (SCR) system, but is also a tempered drinker and produces less CO2 emissions. Still, Opel hasn't detailed the actual figures, but we don't expect a very dramatic change in fuel economy and greenhouse gas emissions over what the current 2.0 CDTI prides itself with.

Some highlight elements of the all-new 2.0 CDTI mill include re-profiled intake ports, a fuel injection system operating at 2,000 bar that delivers up to 10 injections per cylinder cycle and a new design combustion chamber. Opel says the new engine is also very refined, producing little vibrations and low noise levels when operating, which is nice.

To remove nitrogen oxide (NOx) from the exhaust gases, engineers employed BlueInjection, a system that injects AdBlue into the exhaust gas before entering the catalytic converter. A few new cars, but mostly big trucks use AdBlue. The AdBlue solution can be purchased at virtually any petrol station and it's stored in a tank, which can be topped up via a nozzle adjacent to the vehicle’s fuel filler cap.

Available next year, the new 2.0 CDTI is the first in a new family of large oil burners developed in-house by a global team of engineers in Turin and Russelsheim, supported by engineers in North America.
