As things become measurable, the 12C starts to dominate. The 3.3sec 0-60mph time we recorded is pretty impressive, given that it equals the time we set in the dry for the Ferrari 458, but was recorded on a showery day with traction at a premium.
By 100mph under full acceleration the 12C’s 616bhp really asserts itself, allowing it to post a time of 6.7sec. It will cover the standing quarter mile in 11.1sec (with a terminal speed 131.5mph) and the standing kilometre in 20sec dead.
In short, the 12C is ferociously, apocalyptically quick. The minutiae will keep statisticians at it for a month, but basically, little else with four wheels, a windscreen and number plates will keep up with a 12C on full chat.
The quality of the McLaren’s noise is also impressive. At idle it makes a relatively purposeful burble and its turbos mean performance is strong even from very low revs, although it is naturally fastest towards its 8500rpm cut-off.
To say it ever bogs down would be an overstatement, but big normally aspirated engines such as Mercedes SLS’s 6.3-litre V8 are initially a little quicker to respond. Once over, say, 4000rpm, the needle truly flies around the tacho dial.
