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.

Jaguar Land Rover to drop supercharged V8 for turbocharged BMW power

There are few things that sound as good as Jaguar's 5.0 liter supercharged V8. As great as it is when the supercharger whines or the exhaust cracks and pops on throttle lift-off as the air pressure equalizes, the basic design dates back to the '90s. Plainly, the engine isn't as efficient as it needs to be, but designing a new V8 from the ground up is an expensive proposition. Instead, Automobile reports that Jaguar Land Rover is set to use a twin-turbocharged V8s supplied by BMW. Scalable architecture is all the rage as automakers streamline designs in order to save costs. For example, Jaguar's current supercharged V6 is quite literally a V8 with two holes missing. They didn't even change the length of the block. It seems both of those designs are on their way out, with the V6 being replaced by a inline-six closely related to the company's inline four. It seems that rather than designing an new and expensive V8 for their top of the line models JLR, is sourcing from BMW. From 1994 to 2000, BMW owned Land Rover. A few models, including the Land Rover Range Rover, used BMW engines then and in the initial years of Ford's JLR stewardship. It seems things have now come full circle. BMW currently makes a twin-turbo 4.4 liter V8 that produces anywhere from 440 to 600 horsepower, depending on the application. Automobile says that a new 4.0 liter V8 is in the works and that it will most likely be the engine that JLR uses. Expect it to be more powerful, more fuel efficient, and lighter than what both BMW and JLR currently offer. This seems like a win for both companies. BMW gets to offset the cost of a new motor while JLR, a smaller company, doesn't have to invest in a whole new architecture. As automakers search for ways to cut costs, expect collaborations like this to continue. Infiniti and Mercedes-Benz both share a four-cylinder engine. Ford and GM have worked together to design a shared 10-speed automatic. While we may lament the loss of that wonderful Jaguar Land Rover engine, we can still be happy that they haven't abandoned the V8.
