Aston One-77: on track
Posted: 28 May 2012
The One-77 in these pics, built last July and one of four mules running around in various parts of the world, was always going to travel the fastest because it’s the engine and transmission calibration car. It has done 1,800 miles, and exists primarily to make sure the big Aston's 7.3-litre normally aspirated V12 engine, co-developed with Cosworth, works as it should in all conditions.
Mule KX09 LHR started life doing a lot of time-consuming work at low speed. Dull to the layman, but interesting for Porritt. Shunting to and fro in car parks, making sure the engine starts properly and returns to idle, making sure the new six-speed paddle-shift transmission works as it should, and also spending a lot of time on the dyno. All went to plan, then its first proper test happened at Nardo in December, where it achieved a maximum of 220.007mph.
