WITH six-speed gearboxes all-round, Euro5 and five-star ENCAP ratings, four-cylinder-only powerplants, three diesel engine choices, two body styles and a single petrol engine variant, the fresh 508 represents Peugeot’s most thorough attack on the medium and large car segments in a generation. After the disappointing 407, the 508 offers space, comfort and quality with high-tech driveability and eco features to take on everything from the Hyundai i45 to a Holden Calais. We drive the GT sedan.
