The Peugeot 508, which will be introduced at the Paris Motor Show this October, continues the three-digit tradition set by the 40 series and 50 series sedans. The 508’s design resembles the SR1 Concept car, and features a new high-tech interior and high quality finish.
The 508 will be offered with a new array of petrol, diesel and hybrid engines. Potential buyers will appreciate the new technologies offered with the car.
The list includes Peugeot’s e-HDi system, which is basically a new-generation stop/start system with better driveability and economy. The carmaker also has plans to build a HYbrid4 version with a 147kW diesel and all-wheel drive potential and CO2 emissions of only 99 g/km.
Similar to past Peugeots, the suspension has been set up for both high comfort levels and roadholding.
And just like the 407, the 508 will be offered as a sedan and wagon (dubbed as the SW). The sedan, which measures at 4790mm, is 99mm longer than the 407 while the 4810mm long SW is 45mm longer.
The 508 is based on PSA-Peugeot Citroen’s platform 3 shared with the Citroen C5. Production of the 508 will be in Rennes-La-Janais, in France, for the European market.
In terms of road-holding capability, Peugeot’s vehicles have always been on top, even in the M2 segment. Of course, the Peugeot 508 is able to provide exacting driving pleasure thanks to this capability. In particular, the 508 features two types of suspension – a McPherson type for the front axle and a multi-arm rear suspension for the rear axle.
For the front axle, a new McPherson type was developed based on platform 3, allowing the majority of the Peugeot 508 range to offer both road holding and ride comfort as expected of vehicles in the "M2" segment. With this type of suspension installed on front, Peugeot was also able to not only offer superior road holding and ride comfort, but also reduce weight.
In fact, the new front axle on the 508 is around 12 kg lighter than that of the 407. One version of the model – the Peugeot 508 "GT" – comes with a drop link dual wishbone front axle. With the dual wishbone as well as the decoupling of bounce and steering functions, it provides for a very rigid body and driving accuracy.
Of course, having a drop link dual wishbone front axle on the Peugeot 508 "GT" is purely coherent with the fact that this version is powered by a new 2.2 liter HDi FAP engine that develops up to 150 kW (204 bhp).
On the rear of all the versions of the Peugeot 508 is a multi-arm rear suspension, which is engineered to deliver superb efficiency and maximum accuracy and vibration damping through decoupling longitudinal and transverse forces.
Amazingly, the 508 features adaptive steering. It is armed with a rack and pinion electro-hydraulic steering that adjusts the required steering effort and allows for easy maneuvering even at low speeds. Adaptive steering allows the 508 to adapt to two different driving styles -- "all encompassing" or "GT – as demanded and expected by their respective customers.
Aside from adaptive steering, the Peugeot 508 features a braking system that corresponds to the attributes of each version. For instance, the 508 comes available with front brake calipers in three different sizes -- 340 x 30 mm for the 2.2 liter HDi FAP 150 kW version and 283 x 26 mm or 304 x 28 mm for the rest of the range.
Rear brake calipers come in only one size -- 290 x 12 mm. All Peugeot 508 models feature the latest-generation ESP, which includes CDS (stability control), REF (electronic brake force distribution), and AFU (emergency brake assist) as well as Hill Assist and intelligent traction control. Intelligent traction control helps make the 508 more capable of driving off and on slippery road surfaces by exacting more or less wheel slip on each of the front wheels.
