Race The Runway at Edinburgh airport to raise money for charity we leapt at the chance.

In total, 25 cars took part in the race which was held over a distance of 1350 meters to

a back drop of passenger jets taking off and landing.

I'm going to be driving this... no pressure

The SLS GT has a 6.2-litre V8 with 583bhp. It might not be quite as powerful as the SLS

Black Series, but less downforce means its top speed is higher at 199mph. But how close

could I get to that?

Yes was a terrible start -- but I'm claiming the other car jumped the gun. But it wouldn't

matter anyway....

Actually I crossed the line doing 170.6mph in 26.94 seconds. The C63: 27.27 seconds at

168.8mph.

We managed to capture some of the other races held that day including one against a Lamborghini

Aventador and a Mercedes SL63AMG

The Lamborghini crossed the finish line in 24.65 seconds at 181.6mph. The SL63: 26.94

seconds at 172.2mph.

Next Race was a C63 AMG Black Series against Holden's version of the Vauxhall VXR8.

The C63 recorded 28.77 seconds at 160.3mph. The Holden: 30.71 seconds at 137.1mph

Another race, another Mercedes - this time an E63 AMG S Estate. It raced a BMW M3 GTS.

The M3 GTS did 28.75 seconds at 145.6mph. The E63S Estate: 27.77 seconds at 155.1 mph.

The penultimate race we filmed was between a Ferrari FF and a Porsche 911 Turbo. This,

is what happened.

The Ferrari recoded 25.82 seconds at 175.6 mph. The Porsche 26.03 seconds at 167.6mph.

This meant that the two fastest cars on the day were both Italian. The FF and the Aventador.

And after a flyby from a Supermarine Spitfire we got to find out what would happen when

the Lamborghini and Ferrari went head-to-head....
