Dynamic duo of new BMW M SUVs swoops in

HOT on the heels of the updated X5 and X6 (Issue 1,766), BMW has officially unveiled its X5 M and X6 M performance SUVs, both of which will be available in Competition form only.

This pairing marks the first time that BMW has offered 48-volt mild-hybrid technology on any of its M division models, and the small electrical boost supports a new 4.4-litre twin-turbo V8 petrol engine. Total power stands at 626bhp for both models, while the hottest X5 and X6 also produce a total of 750Nm of torque, available from 1,800rpm and sustained until 5,800rpm.

That's sufficient for a 3.6-second 0-62mph time in both machines, but from 0-124mph the X6 M is 0.2 seconds quicker, at 13.6 seconds, thanks to its more aerodynamic shape. Both cars' top speed is limited to 155mph, but this can be raised to 180mph with the optional M Driver's Package.
