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.

NHTSA releases updated Takata airbag recalled cars list, but it still has errors

Unfortunately, the government's list still contains errors.
The National Highway Traffic Safety Administration has issued an updated list of vehicle models that it's urging owners to repair under the mushrooming Takata airbag inflator recall. The latest version adds vehicles from new automakers like Subaru and Ford that are missing from the original announcement, and it also removes erroneous entries from General Motors, leaving only the 2005 Saab 9-2X (a reskinned Subaru WRX), and the 2003-2005 Pontiac Vibe, a joint project with Toyota.

BMW Competition Edition: 'ultimate version' of M5

BMW isn't waiting to see how much power the upcoming Mercedes-AMG E63 will have and is firmly placing itself at the top of the performance list with a new edition of the M5. BMW claims the M5 Competition Edition is the ultimate version of the sedan and will be limited to 200 models. BMW has confirmed that the vehicle will only be sold in Europe, which makes sense as the automaker just announced a US-only edition. The Competition Edition utilizes the same platform as the M5 with the Competition Package. The M5's twin-turbocharged 4.4-liter V8 receives an updated ECU and an increase in boost pressure for 40 more horsepower and 16 pound-feet of torque. The special edition now puts out 600 hp and 516 lb.-ft. of torque. With the M dual-clutch transmission as standard, the sedan takes 3.9 seconds to get to 62 mph from a standstill. The M5 Competition Edition also benefits from all of the go-fast goodies found in the Competition Package, which include: a recalibrated differential, special steering calibration, a reprogrammed M chassis control system, and an upgraded and lowered suspension. The limited-edition model will be finished in two body colors, Carbon Black and Mineral White, both of which are metallic, while the exterior is adorned with carbon fiber. The rear diffuser, spoiler, and mirror caps are all finished in carbon fiber, with the kidney grilles and side gills wear a "M5 Competition" badge. A unique set of black wheels wrapped in performance tires rounds out the exterior touches. On the inside, the M5 Competition Edition is finished in Merino Black leather with contrast stitching in Opal White. Even the floor mats, which are black, have Merino Opal White bordering. "///M5" is prominently embroidered on the performance seats' headrests, while the carbon-fiber interior trim bears a plaque (one to 200) to indicate the vehicle's limited quantity. All of the special editions will come with a Bang & Olufsen stereo system in addition to a host of high-tech features. The M5 Competition Edition is currently available for approximately $142,696 or roughly $42,000 over a M5 with the Competition Package.
