The new Opel Corsa turbo-diesel ought to represent an exemplary automobile to environmentally-friendly types around the world; an official release from Opel quotes emissions at a scant 82 grams CO2 per kilometer. For comparison, that’s a bit better than even the European-spec Toyota Prius.
Part of that has to do with the engine; the 1.3-liter CDTI (Common-rail Diesel Turbo-Intercooler) is an expert at sipping – not gulping – fuel. In this application, the EcoFlex is fitted with Automatic Start/Stop, and still manages a commendable 140 lb-ft of torque and 95 HP.
Coupled to that mill is perhaps the real trick up the Corsa Diesel’s sleeve: a five-speed Easytronic 3.0 automated-manual transmission. Opel claims that the 5-speed has less weight and less internal friction than a conventional automatic gearbox, lending the Opel all the benefit to efficiency of a manual transmission with the ease of automatic shifting. Plus, the gear spread is nice and wide, allowing the torque-happy little powerplant to run at low speeds.
Add to that brake energy recuperation and low rolling-resistance tires, and the 2015 Opel Corsa CDTI achieves an astonishing 3.1-liters per 100 km. That’s around 76 miles per gallon.
The new Opel Corsa CDTI becomes available in Germany starting this March.
