New Peugeot 508 engine details revealed

The Peugeot 407 replacement will boast 1.6-litre and 2.0-litre diesel engines, the latter offering 140bhp, 163bhp and 204bhp variations, as well as a range-topping 2.2-litre HDi FAP 204bhp.

The 2.2 HDi offers maximum torque of 450Nm and is only available with the top ‘GT’ trim level and is matched to a six-speed automatic gearbox. The engine offers better performance than the larger 2.7 HDi currently offered with the 407 but reduces CO2 emissions by 33 per cent from 223g/km to just 150g/km.

Alongside the diesel engines, 1.6-litre VTi 120bhp and a 1.6-litre THP 156bhp petrol engines are also offered with both body styles, delivering emissions as low as 144g/km with the 120bhp unit.

The lowest emissions in the range however, can be found in the smallest 1.6-litre diesel offering. Peugeot has included e-HDi – or StartStop technology -on the 508 for the first time.

The technology turns off the engine when the car is stopped in traffic jams or at lights to save energy. In the case of the new 508, it reduces emissions by up to 15 per cent in town to an ultra-low 109g/km.

Fuel economy is an impressive 53.4mpg with the StartStop technology, and Peugeot expects it to rise to around 56mpg by the time the model is launched in 2011 once electronically controlled air intakes are introduced.

The lowered emissions are expected to attract business users to the 508 and boost Peugeot’s fleet sales in the UK.

The Peugeot 508 will only arrive in the UK in 2011, and more information is expected in the months leading up to launch, but Peugeot has confirmed it will feature a new single grille and LED daytime running headlamps as seen on the SR1 concept car.
