BMW recalls over 76k 2012-2014 models over brake failure

Bimmerfest is reporting that BMW has notified the National Highway Traffic Safety Administration of its intention to voluntarily recall more than 75,000 3 Series, 5 Series, X1, X3 and Z4 models due to a possible loss of power brake assist that could result in the vehicles failing to stop. The recall affects 2012-2014 models equipped with either the N20 or N26 engine produced from May 2012 to August 2013. Until recall repairs have been performed, BMW dealers will discontinue selling or delivering any affected vehicles in their inventories.
The problem has been traced to restricted oil supply from the intake camshaft to the brake vacuum pump, which may cause the brake vacuum pump to fail, resulting in a loss of power brake assist. While the hydraulic brakes will still function, the driver must much apply greater pedal pressure and the distance required to stop the vehicle will increase.
BMW has reported three minor accidents with no confirmed injuries. According to Bimmerfest, drivers who encounter a braking problem should "pull the emergency brake and apply as much brake pedal pressure as possible. If your BMW has an electronic parking brake pull up and hold the switch to engage the brake." Drivers should then park in a safe location and contact BMW Roadside Assistance.

BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Hamann M6 Gran Coupe is all flared and shiny

Oh, Hamann. After rolling out the ridiculously pink Mystère at this year's Geneva Motor Show, the tuning company has worked its mirror-finishing magic on the BMW M6 Gran Coupe, debuting this, the aptly named "Mirror" at the Frankfurt Motor Show. It sure is shiny, and a full 40 millimeters wider than the standard M6 GC.
Hamann says that the, um, "tailor-made suit" exterior treatment is made up of a new front bumper spoiler with large air intakes, side skirts, a new rear spoiler, and wing extensions out back. And the end result is... well, let's just call it noticeable. The special BMW rides on unique 21-inch wheels and sits a full 25 millimeters closer to the ground, as well.
As far as we can tell, Hamann hasn't upgraded the M6's 4.4-liter twin-turbo V8 at all, though there's a new sport exhaust system that "depending on the application area, either noisily announce its presence or purr sportily." Sounds like it's as loud as its newfound appearance.
