A super-efficient 1.3 litre common-rail turbo diesel and the basis for the engine in the Vauxhall/Opel ECO-Speedster world record challenger – the car topped 111 miles per gallon over the weekend – is at the heart of power choices in the new edition Corsa due in the autumn.

The 1248 cc ECOTEC engine is the smallest four-cylinder diesel in the world, but when it comes to performance and torque it is a match for much bigger engines.

As well as its economy – it returns 62.7 mpg in the combined driving mode – its exhaust emissions (122 g/100 km) and refinement make it one of the best diesels around.

The new engine produces 70 hp at 4000 rpm and maximum torque of 170 Nm is available between 1750 and 2500 rpm. The Corsa 1.3 CDTI reaches 60 mph in 13.5 seconds with a 103 mph top speed.

The 16v engine uses a cast iron block (bore x stroke: 69.6 x 82.0 mm) with a light-alloy cylinder head. A multi-jet direct injection system is supplied with fuel via a common-rail system at a pressure of 1400 bar.

It is the first jointly-developed engine from the Opel/GM-Fiat powertrain venture.
