The M5 has been unleashed.
Official details of BMW’s new M5 super sedan have been released, after images and vital details were leaked online a week ahead of their scheduled debut.
The new M5 will be powered by the same 4.4-litre twin-turbocharged V8 engine as the brand’s X5 and X6 M models, following a trend from manufacturers to downsize their engines in order to save fuel.
Despite the smaller engine (the existing M5 was fitted with a 5.0-litre V10 powerplant) the new super sedan will produce a few extra kilowatts over BMW’s M-badged SUV models – 412kW compared to 408kW – about 10 per cent more than its predecessor (373kW). That also puts it ahead of its main rival, Mercedes-Benz’s E63 AMG, which produces 386kW from its 5.5-litre twin turbo V8 (or 410kW with the optional performance pack).
Torque output from the new 4.4-litre twin-turbo engine doesn’t change from the X5 and X6 M models at 680Nm, representing a jump of 30 per cent over the old V10 engine. That figure, however, is slightly lower than the standard E63 AMG’s, which produces 700Nm as standard or 800Nm with the go-fast package.
