Peugeot premiere advanced HDi 170 diesel engine in 407
Peugeot, always at the forefront of diesel technology, is strengthening its position with the arrival of an exceptional new diesel engine to compete in the medium segment.
Saloon and SW models of the distinctive 407 range will soon be available with the advanced new 170bhp 2.2-litre HDi engine – the first 4-cylinder engine to use twin-turbochargers, managed by a parallel sequential induction system.
The 2.2-litre HDi is an evolution of the existing 2.2 DW12 TED4 engine, and utilises the latest advances in diesel technology by combining power, refinement and excellent fuel economy. It is the fourth phase of the cooperation between PSA Peugeot Citroën and the Ford Motor Company (initiated in 1998).
The quest to deliver an outstanding state of the art diesel engine has resulted in the creation of a twin turbocharged, parallel sequential induction system that gives unrivalled levels of power and responsiveness, even at low revs. The first low inertia turbo operates up to 2,700rpm, and gives an immediate response to throttle input. As the revs rise, the second, smaller turbo kicks in seamlessly to give enhanced performance throughout the rest of the rev range.
The new HDi 170 is fully compliant with Euro 4 regulations, produces a maximum torque output of 277lb ft at only 1,500rpm and is mated to a six-speed manual transmission. The engine will be available in 407 Sport derivatives, and is priced at £21,100 OTR for the Saloon and £22,300 OTR for the SW version.
