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 says X5 xDrive40e PHEV will get 55 MPGe

This is one vehicle that Sammy Hagar can actually drive 55. Miles on the equivalent of a gallon of gas, that is. BMW has starting talking about details of its first-ever production plug-in hybrid CUV, and the latest are centered on the model's projected miles per gallon-equivalent figure. Bimmer is now saying the its X5 xDrive40e PHEV will get a robust 55 MPGe on the US EPA scale (on the European scale, the vehicle's expected 77 or 78 grams of CO2 per kilometer would translate to around 70 mpg). The model, which pairs 2.0-liter twin-turbo four-cylinder engine with an electric motor, will be able to go as far as 13 miles on electricity alone, and also hit 75 miles per hour using just the battery. BMW first unveiled the model at the Frankfurt Motor Show in 2013. The CUV, which will have full-time all-wheel drive, will have some guts, too. The model will deliver 308 horsepower, including 111 from the electric motor alone. As a result, the X5 xDrive40e will be able to scoot from 0-60 miles per hour in 6.5 seconds. Not exactly Tesla Model S quick, but peppy nevertheless. US and European sales for the model-year 2016 version will start this fall. The model will be produced at the company's plant in Spartanburg, SC. Take a look at BMW's press release below.

The first plug-in hybrid BMW Sports Activity Vehicle Up to 13 miles of zero-tailpipe-emission pure electric driving Preliminary fuel economy estimates up to 55 MPGe 0-60 mph in just 6.5 seconds Woodcliff Lake, N.J. – March 17, 2015 ... The BMW X5 xDrive40e, the company's first plug-in hybrid Sports Activity Vehicle, charts the next chapter of BMW's ongoing EfficientDynamics initiative. Benefitting from the groundbreaking work by BMW i on electromobility, the X5 xDrive40e combines the company's award-winning 2.0-liter TwinPower Turbo four-cylinder engine with an electric motor, powered by a lithium-ion battery, integrated into its 8-speed automatic transmission. This newest BMW SAV can travel approximately 13 miles on pure electric power, ideally suited to short commutes and quick trips around town. Working in concert, the gasoline engine and electric motor puts out 308 horsepower and produces 332 lb-ft, enough to propel the X5 xDrive40e from 0-60mph in just 6.5 seconds.

Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.
