Mercedes S 500 Plug-In Hybrid price & specs – costs from £87,965

The Mercedes S500 Plug-in Hybrid arrives in the UK It’s more than a year since the Mercedes S500 Plug-in Hybrid was revealed, and now it’s finally going on sale in the UK and, if your pockets are deep enough, it offers a perfect ‘cake and eat it’ car. Under the skin there’s a 3.0 litre V6 biturbo delivering 329bhp and an electric motor adding a further 116bhp which together give the S500 Plug-in the ability to blat to 62mph in just 5.2 seconds but return official economy of 100.9 mpg and emissions of a measly 65g/km. That combination means that you won’t have to pay Boris to drive through London, and your BIK rate will be a very modest 5 per cent, making the S500 plug-in Hybrid a perfect choice for every board member in the country currently paying 35 per cent on their petrol S500, BMW 7 Series or Audi A8.

He might be behind the wheel of one of his five hundred cars, which includes such rarities as the Kia T-600 (Kia's first car, built under license from Mazda in 1963); the Cadillac Fleetwood of former president Park Chung-hee; and Korea's oldest fire truck.
