The worlds most Powerful Road Cars
ULTIMATE AERO XT 1 and 318HP
There have been a few Ultimate Aero versions over the years, but the XT is the, er, ultimate. Unsurprisingly, it uses a twin turbo V8. It s obviously the recipe of choice for big power. Amazing that at 7.0 litres in capacity it ll rev to 9,200rpm kicking out 1,318 ponies, that s a lot of horsepower.
