From this weekend’s final Top Gear of the season, Richard Hammond gets behind the wheel of BMW’s M5 F10M. Powered by a twin-turbocharged 4.4 V8 unit, which develops 412 kW (560 hp), the M5 hits 100 km/h (62 mph) in 4.4 seconds while its limited 250 km/h (155 mph) top speed climbs to 305 km/h (190 mph) with the M Driver’s Package. Shame there wasn’t a little more M1 content.
