The Spider weighs only 40kg more than it's hardtop sibling - 1474kg - and incorporates all the revisions that were recently made to that car.
0-60mph is 3.1 seconds and 0-124mph is 9 seconds! The 0-60 time is the same as the tin-top version whilst 0-124 is only two tenths of a second slower. An F1 car gets to 124mph in about 5 seconds.
The Spider is released in November and will cost £195,500 - almost £20,000 more than the coupe.
Amazingly it will return 24.2mpg. An F1 car does about 3mpg.
