BMW M5

With its massive, turbocharged V8 engine, the BMW M5 has huge reserves of power and performance and is packed with Formula One-derived technology. There's a seven-speed semi-automatic gearbox and electronically controlled suspension that can be tuned for comfort or speed using simple steering wheel mounted buttons. In fact, almost everything can be electronically fine-tuned to suit the driver - from steering feel to gear-shift speed. Impressively, the M5 remains every bit as appealing as practical as the standard 5 Series, and gets a  well-made cabin, a huge boot and genuine everyday usability. Optional sports leather seats are very comfortable, while technology fans are sure to love the head-up-display and huge 10.2 inch satellite navigation screen. The car is aimed at rivals like the Mercedes-Benz E-Class E 63 AMG, but the M5 claims to be the drivers favourite - something we would definitely agree with.

The car features a 4.4-litre twin-turbocharged V8 engine that produces 552bhp and 680Nm of torque. Put simply, that's enough to propel the big saloon from 0-62mph in only 4.4 seconds... And if you chose to specify the M Driver's "Tuning package" it will have enough power to hit 190mph. "Fast" isn't a word that does this car justice. From steering response to gearbox shift times, almost everything can be electronically fine-tuned to suit the driver. But however you choose to set this car's handling balance, rest assured that the M5 is never less than thrilling to drive. With the car in third gear, thrust from the engine is simply mind blowing. There is a vast amount of grip on offer from the big tyres
