The Peugeot 508 is a smooth and easy car to drive, with soft, supple suspension and agile handling at high and low speeds. There are no petrols in the engine line-up anymore, which means the powertrains are limited to diesels, but the 508 is offered with the Hybrid4 powertrain, with 200PS and 95g/km of CO2.

The range opens with the 1.6 BlueHDi with 120PS, which is sufficient for general motoring with 300Nm of torque and up to 70.6mpg.  However, while the 1.6-litre pulls well enough through the gears, 0-62mph takes 11 seconds and things can get a bit noisy and breathless when joining a busy motorway.

We'd recommend upgrading to the 2.0-litre diesel with 150PS. Not only is it more powerful for overtaking with 370Nm of torque, but it's also cheaper to run with up to 72.4mpg. We also found the 2.0-litre to be quieter and more refined, with less considerably less noise at motorway speeds. A 180PS version is available for those who want to cover 0-62mph in under nine seconds, but this cuts economy to 67.3mpg and is limited to the range topping GT models. 

None of the standard diesels dip below 100g/km of CO2, but company car drivers can opt for the 200PS Hybrid4, which combines a 2.0-litre diesel with an electric hybrid system to lower emissions to 95g/km. Unlike the standard 508 that is front-wheel drive, the hybrid employs four-wheel drive to provide a lot more grip in the corners. 

When the 508 was launched in 2011 the range included a 2.2 litre 204PS diesel, along with two - 120PS and 160PS - 1.6-litre petrols, but these were dropped as part of the 2014 update. The 2.2 diesel is commendable, with lots of pace, but neither of the petrols are recommended due to poor economy and performance.  

On the road the 508 is generally quiet and agile at both high and low speeds. The large windscreen provides lots of visibility and almost all models get hill hold assist and blind spot monitoring, which makes the 508 an easy car to drive in town or on the motorway. The steering is responsive too for a car of this size, providing safe and predictable travel on A and B roads. The drive can be sharpened up with GT Line trim, with large wheels and improved suspension, but this pushes the 508's price into BMW 3 Series territory.
