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.

BMW rethinks all-wheel-drive M cars

BMW M hasn't been able to decide whether it wants to jump on the all-wheel-drive bandwagon or not (with the exceptions of the X5 M and the X6 M, which are based on AWD architecture). That might be changing though, since M's president Friedrich Nitschke recently realized that 70 to 80 percent of Mercedes-Benz E63 AMGs are ordered with all-wheel drive. Earlier this year, Nitschke said that there were no new AWD M models planned, so this comes as somewhat of a surprise.
"On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in a Motoring report. "That's the timing and it's not practical to react in the current life cycles."

Reverse-engineering i3 shows BMW profits after 20,000 sales

"This is, without a question of a doubt, the most advanced vehicle on the planet. It's as revolutionary as the Model T was when it came out." That is exceptionally high praise, and it's not even being heaped on one of the million-dollar hybrid hypercars from Ferrari or McLaren. It's not even being attributed to a particularly zealous Tesla fan. Nope, it's coming from a mustachioed man in suburban Detroit, and he's discussing a $42,400 BMW hatchback with Forbes. Of course, said hatchback is the revolutionary i3, and Sandy Munro's statements carry some degree of authority, as his company is tearing apart and analyzing every little nut, washer and bolt on the four-seat EV. Munro's eponymous company performs reverse-engineering analysis, meaning they rip apart brand new cars and sell the information to the world's automakers, saving OEM's both time and money. The most interesting thing it has discovered thus far? That even with the high costs of two of the i3's most important elements – carbon-fiber-reinforced plastic and lithium-ion batteries – his company's analysis shows that BMW need only sell about 20,000 units a year to turn a profit, Forbes reports. While Munro's company is often contracted by automakers, he's gone it alone on the i3 project, dropping about $1 million into in-depth analysis. That's a lot of money, but the company should be able to turn around and sell its findings for about $500,000, with a batch of Chinese automakers already queued up and ready to buy. Analysis of individual i3 components will also be available from a sort of a la carte menu. To see what it is about the i3 that has Munro speaking so highly of it, head over to the Forbes website and check out the feature article and video on the reverse-engineering process.
