Peugeot's latest clean, green diesel engine now in the 406

The latest model to feature Peugeot's revolutionary HDi diesel engine with particulate filter is appearing in Peugeot showrooms now.

The new Peugeot 406 2.2 HDi combines reduced emissions with increased fuel economy and pulling power that comes close to the range-topping 3.0 litre V6 petrol version.

The 2.2-litre HDi diesel engine has been introduced in the 406 in order to meet the increasing demands from diesel owners for more power.

"Peugeot's HDi range of diesel engines is helping to change the traditional image of diesel-powered cars.

"Common perception in the UK may still be that they are slow, noisy, smelly and dirty, but the truth is that technological developments have transformed diesel engines in recent years and the UK general public is starting to take note of this fact. A modern, direct injection diesel engine is actually more environmentally-friendly than its petrol equivalent," said Tod Evans, Peugeot UK's managing director.

The 406 2.2 HDi boasts 44% more torque than its petrol equivalent (406 SRi 2.2), has a top speed of 126 mph and goes from 0-62mph in just 10.2 seconds. The new model is 33% more fuel-efficient than the petrol-powered version, and produces 19% less CO2 emissions.

These reductions are achieved through three areas of technological development: direct injection of the fuel into the cylinders; 'common rail' – i.e. the supply of fuel to the cylinders under enormous pressure by a common pipe, and the innovative 'FAP' particulate filter. This catches the particles that form the visible smoke in the exhaust of a diesel engine, and automatically burns them off at regular intervals. As a consequence, Peugeot's HDi engines produce no smoke over 95% of their operating range.

The 2.2 HDi engine is available on GTX and Executive saloon and estate models.
