Audi has decided to change it's naming convention on the new A8, with what would have been the 3.0 petrol replaced by the numbers 55, which the brand is now using to represent any car with between 305 and 422 horsepower, so the 3.0 TFSI becomes the 55 TFSI. This is because the brand expects to move to more electric and hybrid cars soon and as electric cars don't have an engine capacity a new formula was needed. This particular engine now has 340 bhp and with the change over from diesel to petrol in full swing it's set to be a popular model. 0-60 time is a rapid 5.6 seconds along with a top speed limited to 155 mph. Quattro 4 wheel drive is standard, as is a new 48V electrical system that gives the car a mild hybrid status, which allows for engine off coasting and longer stop-start capabilities. Inside the car is beautifully put together with all of the luxuries and safety systems you'd ever expect and to quote Autocar magazine "your first impression is of a car built to outlast civilisation itself".
