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.
