Peugeot 508 - Technical Highlights

Technical Highlights

Peugeot has equipped the European-market 508 with its HDI common-rail diesel engines. The 1.6-litre HDI 112 can be fitted with the e-HDI 'micro hybrid' system, including an electronically-controlled automatic gearbox, which reduces fuel consumption to 67.2 mpg (4.20 L/100 km; 56.0 mpg) with CO₂ emissions of 109 g/km. Though this matches the Volkswagen Passat Bluemotion, it features a slightly larger fuel tank which allows it to cover a slightly longer range of 1017 miles.

At least two e-hdi engines are available in 2011 and 2012. The first engines had emission of 114 g/km. The later model reduces emissions to 109 g/km. A modified air intake is the cause.

The 508 range will also include PSA's HYbrid4 diesel-electric hybrid powertrain, which will reduce fuel consumption further, to 74.3 mpg (3.80 L/100 km; 61.9 mpg) with CO₂ emissions of 99 g/km.

The top GT version comes with a 201 bhp (150 kW; 204 PS), 2.2-litre turbodiesel engine which generates 338 lb·ft (458 N·m) of torque. It comes mated solely to a six-speed torque converter automatic gearbox which offers manual shifts via paddles or a central selector.
