Upgraded McLaren MP4-12C, with added drama

Another day, another upgraded supercar: hot on the heels of yesterday's news of the Mercedes SLS AMG GT comes news of more power for the McLaren MP4-12C.

The 2013 Model Year car goes up from 600 PS to 625 PS from 3.8 litres. That means it is almost the same as the original McLaren F1, which had 627 PS from its 6.1 litre V12 – that is a measure of the increase in engine efficiency over the last 20 years (and the benefits of turbocharging).
