BMW rides high with new M models You might see the BMW X5 M (below) and X6 M at the Clearwater Bay Golf & Country Club on Tuesday. BMW Concessionaires (HK) plans to present the fasties to local media at 11.30am that day. The xDrive four-wheel drives are worth a look, if only to see how the tall rides negotiate the speedbumps on the club's drive. The marque is proud of its twin-turbocharged 555hp 4.4-litre V8 block, which it says 'heralds the launch of the most powerful road-going M car the company has ever launched'. Fitted with M Sport Automatic transmission and capable of 680Nm of torque between 1,500rpm and 5,650rpm, the X5 M (tentatively HK$1.6 million) and X6 M (tentatively HK$1.7 million) can sprint like an M3 to 100km/h in 4.7 seconds and top at 250km/h. Such oomph lies in the design of the V8, the marque says. 'In a world first for an M-badged vehicle, both the turbochargers and the catalytic converter are within the vee of the powerplant,' BMW says. '[The] engine breathes better and operates at a higher efficiency due to the shorter exit manifold.' Fitted with M Sport seats and packed with the marque's latest electronics, the cars seem spacious for foursomes' flits to golf, with 620 to 1,750 litres of boot in the BMW X5 M and 570 to 1,450 litres in the X6 M. Watch the speedbumps.
