Detroit motor show 2009 - Ford Shelby Mustang GT500

This is the 540bhp Shelby Mustang GT500 – a car that looks so good we feel compelled to write about it, even if it's unlikely to be seen on a British road.

The GT500 goes on sale in the US this spring, and is powered by a supercharged 540bhp 5.4-litre V8 petrol engine with 510lb-ft of pulling power.

That equates to a limited top speed of 155mph, and 0-60mph in less than 4.5 seconds.

High-performance features include a short-throw six-speed manual gearbox, a twin-disc clutch and limited-slip differential.

Aerodynamic enhancements over the previous model also add downforce, while the suspension has been enhanced to sharpen up handling.

However, it's not all about performance – Ford says the new engine is also more efficient.

It's available as a coupe and convertible and, yes, those racing stripes are a must-have accessory.
