Peugeot Twin Turbo Diesel Engine
Wednesday, August 30th, 2006
Although it won’t be coming to North America, Peugeot’s latest diesel development has significant implications, especially for automakers exploring the potential of high-performance compression-ignition engines in an era of rising fuel prices.
In France, Peugeot has just released the 607 HDi 170 sedan. A midrange luxury car, this 607 is powered by a four-cylinder diesel, but its performance is exceptional, considering the engine is only a 2.2-liter unit.
The direct-injection, common-rail diesel engine has been fitted with sequential twin parallel turbochargers — the world’s first such adaptation on a four-cylinder diesel, according to the automaker. The result is 170 horsepower and 277 pound-feet of torque. The first turbo kicks in at low revs, while the second operates in parallel between 2600 and 3200 rpm.
More important, the 607 HDi 170 returns more than 40 miles per gallon on the highway, making it one of the most efficient executive sedans on the road in Europe. The Europeans continue to demonstrate that turbodiesels, even smaller ones, can still deliver exceptional performance, as well as outstanding fuel economy.
