Peugeot 508 SW PSE Is Better On Paper, In Photos Than In Real Life Apr 14, 2021 1m ago ++ Reviewers recommend you avoid it and just go for the plug-in hybrid GT model instead. The Peugeot508 SW has to be one of the best looking wagons on sale anywhere in the world. It just oozes sporty style, but it doesn’t forget practicality, and when you step inside, the interior will wow you with its flamboyant design and premium feel. However, is it a good base for a 355 horsepower sports wagon? But regardless, Peugeot went and did it anyway, and what resulted is the 355 horsepower 508 SW PSE (Station Wagon / Peugeot Sport Engineering). Believe it or not, this car’s main source of motivation is a 197 horsepower 1.6-liter turbocharged engine, but it is helped by a 109 horsepower electric motor that’s built into the eight-speed gearbox and a 111 horsepower electric motor that drives the rear wheels (and occasionally makes the vehicle all-wheel drive).
