BMW has revealed details of its next-generation BMW X5 M and X6 M Competitions, typically the biggest of the M division SUVs. Both X5 and X6 versions will be launched together, and will begin production in April next year.
Both share much of their technical make-up with the M5 Competition, featuring the same ‘S63’ 4.4-litre twin-turbocharged V8 petrol engine with peak figures of 616bhp at 6000rpm, and a table-top 750Nm of torque between 1800 and 5600rpm. Based on the same hot-V turbo layout as in the M5 Competition, response should remain sharp thanks to the high gas flow rate, providing the turbochargers with a fast and smooth flow of exhaust gases to get the two turbochargers spinning much faster than a traditional twin-turbocharger layout. Lesser 592bhp non-Competition versions will be offered in some markets, however their availability in India is uncertain as of now. Both Competition models will reach 100kmph in 3.8sec, 200kmph in 13.5sec and top out at 285kmph if the M Driver’s Package is selected.
Also shared with the M5 Competition is the eight-speed ZF automatic transmission and all-wheel-drive layout, and although it doesn’t have the ability to decouple its front axle, a more rear-biased mode is still able to be selected within the variable M driver modes. Alongside the multi-clutch centre differential, M division has also fitted an active locking rear differential, which is able to apportion power to specific rear wheels as needs dictate. The transmission is also able to be independently varied as per M division tradition, with three gearbox modes selectable outside of the usual M1 and M2 modes via two red steering wheel-mounted buttons.
M division has also paid close attention to the engine’s cooling, designing a bespoke system capable of keeping the powertrain cool even on the racetrack, should you wish to take your 2.3-tonne SUV on one. As well as an offside charge cooler, so too is there an onside oil cooler, and a supplementary electric water pump that activates once the ignition is switched off to keep the water circuit running after hard use.
