2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

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.

2014 BMW X5 recalled over faulty child-safety locks

BMW is set to recall some 6,400 of its new-for-2014 X5 SUVs built between December 12, 2013 and March 10, 2014 due to concerns that the child safety locks, if set, might deactivate without warning. The problem affects only those vehicles with the automatic soft-closing option.
According to the bulletin issued by the National Highway Traffic Safety Administration, the lock mechanism on the rear doors "may not have been manufactured to correct tolerances," meaning the safety locks could disengage with a simple pull of the door handle. Basically, with a pair of tugs, the rear doors could be opened from the inside, regardless of child safety locks.
BMW is in the process of notifying owners of affected vehicles. Any necessary repairs will be conducted free of charge. Take a look below for the official press release from NHTSA.
