This huge sedan offers incredible luxury, comfort and prestige. Under its long hood is a 6.8-litre turbocharged V8 engine that generates 505 horsepower in the “base” trim and 530 in the Speed. The Mulsanne 2017 has had several styling updates and an extended wheelbase version has been added to the line-up. Fair warning to the Rolls-Royce Phantom and Mercedes-Maybach: you have serious competition!
