BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.

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.

BMW i3 takes to the track, circles it in a way you don't expect

So, who wants to see a BMW i3 race around a track. That's what we thought. It's not a long video, but it is entertaining, and the way the urban EV does a 'loop' at second 25 certainly caught out eye. The i3 is scheduled to go on sale in the US later this year and will start at $41,350. The diminutive electric vehicle has a top speed of 93 miles per hour and can hit 62 mph in 7.2 seconds. We found it a hoot to drive, but we're not sure if hardcore BMW performance fans will totally 'get' this car's performance. The i3 is great at what it does, but it wasn't born to hit the race track. After seeing this video, though, we want a crack at it, skinny wheels and all. You can get a behind-the-scenes glimpse here, where Chris Neff writes, "The i3 basically turns in on itself. This is one sharp turning radius, take a look at 24 seconds into the video. We were actually trying to get the i3 to do doughnuts, but the computer would not let the rear brake loose, still, you can see how it held and how sharp we were turning....about 27 times in a row." Watch all 49 seconds below. And wonder with us if whatever aerial device was used to get the shot that ends at four seconds in was destroyed just after the video cuts away.
