To comply with ever tightening efficiency regulations, BMW's fifth generation M5 super saloon swapped it's screaming V10 for a more eco-friendly (but still fiendishly fast) twin-turbo V8.
The 4.4 litre twin turbo V8 produces an impressive 552 bhp and 502 ftlb of torque, the kind of power normally reserved for supercars. This moves the near 2 tonne BMW from 0-60mph in just 4 sec. indeed, to save weight and lower the car's center of gravity, the M5 features a bespoke carbon roof.
Interior is comfortable and full of tech, but could perhaps be a little more special to distinguish it from lesser 5 -series.
The optional 'Performance Package' increases power to 575 hp with a 190mph max (if taken with the 'M Drivers Package'), plus a lowered, more aggressive suspension setup.
Super fast, but lacking the excitement of the 4th gen V10, used M5s now available for around the £25k mark. This represents stunning value for one of the worlds best super salooons.
