Let some numbers set the scene. Maximum speed over 205mph. 0-62mph in 3.7 seconds, 0-124mph in 11 seconds, standing-start kilometre in under 20 seconds. The V12 engine, derived from the Enzo Ferrari's, delivers 620bhp - 40bhp down on the Enzo's figure but who's complaining? - and can rev to a manic 8,400rpm.
Oh, and CO2 emissions are 490g/km - so no cheap road tax for the 599 GTB Fiorano, then...
