The Lexus GS is a premium, rear-wheel drive executive saloon that competes with the Audi A6, BMW 5 Series, Mercedes E-Class and Jaguar XF. The regular model is unusual for its dependence on hybrid drive, while rivals rely for the most part on diesel power. There are just two powertrain choices, both of which pair a petrol engine with an electric motor in a bid to keep fuel consumption and emissions low, and to allow near-silent, electric-only drive for short periods.
A breed apart is the high-performance petrol V8 GS F, which is a proper super saloon producing 471bhp. It’s much more expensive than the hybrids and features a host of sporty styling touches to match its dynamic upgrades.
