BMW brings first diesel 7 Series to US with $82,500* 740Ld xDrive

After almost 40 years on the market, there are probably few things the BMW 7 Series hasn't offered, but when it comes to the US market, one of those things just happens to be a diesel engine. That is all about to change, however, as BMW announced that it will unveil the 2014 740Ld xDrive at the Chicago Auto Show before sales commence later in the spring.
Offered only on long-wheelbase models with standard all-wheel drive, the new diesel 7 is powered by BMW's 3.0-liter inline-six producing 255 horsepower and a stout 413 pound-feet of torque peaking between 1,500 and 3,000 rpm. While BMW has yet to release any type of fuel economy figures, it did say that its diesel technology is usually good for an improvement of 25 to 30 percent over the gas models - just for fun, that means that the 740 Ld xDrive could get as much as 24.7 miles per gallon in the city and 36.4 mpg on the highway, but that's just doing the math and there is nothing official behind those numbers. Acceleration will take a little longer than in the 740Li xDrive (shown above) with BMW stating 6.1 seconds from 0-60 compared to 5.4 seconds for the gas model.
Another small increase over the gas version will be in price, with the 740Ld xDrive getting a starting MSRP of $82,500 (*not including $925 for destination), which is just a $1,500 bump over the 740Li xDrive. For comparison, the Audi A8L TDI starts at $78,800, while the previous-gen Mercedes S350 Bluetec was priced at $93,000. Scroll down for more info on the new diesel-powered 7 Series, and stay tuned to our live coverage from Chicago in a couple weeks as we'll have live images and hopefully more info.

BMW i3s traction control tech going in all BMW, Mini cars

The BMW i3s is essentially a warmed-up version of the i3 electric car we all know and love. The performance boost isn't huge — just 14 horsepower and 15 pound-feet of torque — but it also gets a new suspension, wheels and tires as well as an improved traction control system. We found the car to benefit from all the updates when we drove it for our First Drive Review, but now BMW has offered up more details on just how the traction control system of the i3s helps make it better to drive. The company says it'll expand the technology to all future BMW and Mini models as well. The i3s's system is calibrated to help it to pull away quickly from a stop, making full use of the instantaneous torque offered by the electric motor. It also improves stability when accelerating out of corners, when using regenerative braking and, of course, when the road conditions are less than ideal. The results are palpable, and with the other improvements the i3s definitely feels stronger off the line, as we found on our drive. It's also about a half-second quicker to 60 miles per hour, at 6.8 seconds. The secret is in the response time of the stability control, which BMW claims is 50 times faster than the conventional system. This is made possible by moving the control process into the powertrain itself, rather than a remote unit. This reduces the signal path and, thus, the response time of the traction control system. BMW's Head of Chassis Development, Peter Langen, said of it, "With their high levels of torque and instantaneous responses to every movement of the accelerator, electric motors already make significantly higher demands on driving stability systems than conventional power units." While engineered to make the most of the electric motor, BMW says the shorter cycles of this traction control system show promise for internal combustion vehicles as well. As such, we'll begin to see the improved technology applied across the BMW and Mini lineups going forward. Related Video:

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.
