The Porsche 918 Spyder can deliver a total of 759bhp from its race-derived V8 and two electric motors which, although less than the likely power available to the F70 of P1, is still a significant amount of get up and go.

Highly exclusive Alfa Romeo Disco Volante revealed

EXCLUSIVE Italian coachbuilder Touring has unveiled its Alfa Romeo Disco Volante, which is a modern interpretation of one of the company’s most famous designs. The new Disco Volante marks the 60th anniversary of the original, but the new car comes with a 4.7-litre V8 engine with 450bhp borrowed from the Alfa Romeo 8C supercar. This means the new Disco Volante can see off 0-62mph in 4.2 seconds and has a top speed of 181mph.
