BMW unveils 2016 X5 M and X6 M super CUVs

The second-generation BMW X5 M and X6 M have officially made their arrival for the speed-obsessed, crossover-loving masses that aren't willing to turn to Mercedes-AMG or Land Rover Special Operations.
While the new models retain their 4.4-liter, twin-turbocharged V8s, power has increased from 555 horsepower to 567 ponies. Torque is up more significantly, climbing from 500 pound-feet to 553 pound-feet. The extra twist is slightly less accessible, with peak grunt arriving between 2,200 and 5,000 rpm, rather than the earlier model's 1,500 to 5,650. Still, we'll take the ten percent increase in torque as a net win.
The big powertrain switch sees the old X5/6 M's six-speed automatic replaced with an eight-speed Steptronic transmission from BMW M. This new gearbox feeds power to an xDrive all-wheel-drive system that can variably shuffle up to 100 percent of power to either axle. In conjunction with the force-induced thumper under the hood, this powertrain arrangement allows both M models to hit 60 miles per hour in just four seconds. That's a mightily impressive stat in a 5,000-plus-pound vehicle.

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

BMW pondering hardcore M4 to celebrate 100 years?

2013 is the year for Lamborghini, Aston Martin and the Porsche 911, but 2016 will be the year for BMW. That's when the Munich-based maker of the Ultimate Driving Machine will celebrate its 100th birthday, with what will probably be a year-long celebration. Part of that 365-day party will, reportedly, be an even hotter version of the new BMW M4, which is set to debut in January at the Detroit Auto Show.
Yes, according to Australia's Car Sales, the über-M4 has been hinted at by higher-ups at BMW's M division, who claim the rear seats will be removed, much like the M3 GTS, while other weight-saving measures will be used to try and bring the M4's weight below 3,000 pounds. There's no mention of engine mods, but if the M4's biturbocharged six is as good as we think it'll be, that's not a deal-breaker for us.
The lightening process on the so-called M4 GTS would involve replacing the hood and front fenders with parts made of carbon fiber, while the doors would switch from steel to aluminum. Besides the deletion of the rear seats, Car Sales is predicting lightweight racing buckets, with a carbon-fiber shell and a minimal amount of padding. Expect lots and lots of Alcantara, in place of leather.
