2024 BMW X6 M: Review, Trims, Specs, Price, New Interior Features, Exterior Design, and Specifications | CarBuzz

The engine powering the BMW X6 M Competition is a new V8 motor that, for the first time, is supplemented by a 48V mild-hybrid system. Codenamed S68, the 4.4-liter eight-cylinder that is used in both the X5 M and X6 M for 2024 is tipped to be more efficient and provide sharper responses than the mill in the outgoing model. This is thanks to a reinforced crankshaft drive, turbochargers mounted close to the exhaust manifold, an electrically controlled blow-off valve for the turbos, and a new air intake duct. Outputs are 617 hp at 6,000 rpm and 553 lb-ft of torque between 1,800 and 5,88 rpm – identical to the previous Competition variant – with the electric motor contributing up to 12 hp and 147 lb-ft of torquefill when needed. 0-60 mph is still dispatched in 3.7 seconds, and the top speed is either 155 mph as standard or 177 mph if you tick the box for the M Driver’s Package.

An updated eight-speed M Steptronic gearbox does duty in the 2024 X6 M Competition, and features shorter gear ratios from first to third to enable blistering take-offs. Wider gear ratios after that cater to the X6 M’s attempts to be more efficient with its new powertrain.

BMW intended for sharper shifts here, and the torque converter has been tuned to be be a good companion to the V8. Power gets sent to all four wheels through the xDrive system and active M rear differential. Staying at the rear axle, toe-in values here have been enhanced to make for even more confidence at higher speeds.

The X6 M Competition gets adaptive dampers as standard, and these have been reworked for the most comfort. There are various damper settings in the M Setup menu, and you can choose from Comfort, Sport, or Sport Plus, with the latter modes specifically designed for spirited stints behind the wheel.
