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:

Behind the Scenes of BMW's 'Drift Mob,' Part 2 [w/video]

After spending four days practicing about a dozen drift stunt moves in a parking lot for an upcoming BMW "Drift Mob" internet mini-film, Rhys Millen, Sam Hübinette, Dai Yoshihara, Rich Rutherford, and Conrad Grunewald are finally ready for show time. We are brought to the huge urban traffic circle to see the stunts performed midway through the day to observe for a couple of hours.
The undertaking is massive, with multiple cameras set up, scores of crew members, a helicopter filming from above, a rigged pickup for car-to-car shots, sidewalks lined with security and plenty of curious onlookers, and oh, yeah, a major intersection of a top world city shut down for an entire weekend.
The five drifting legends are nestled in their identical red BMW M235i coupes, which have been modified with special handbrakes but essentially nothing else you can't get on a stock version, and are listening to direction from director Mic Rodgers and stunt coordinator Riley Harper. We're basically given free rein of the set, to shoot the cars, the drivers, and at one point, even hopping in with Yoshihara for one of the admittedly more tame stunts. Even then, the g-forces are so severe that they flip our cameraphone's video recording from landscape mode to portrait. Yes, this is a pretty cool day to be reporting on cars, and as we said during our first installment of our behind the scenes coverage of Drift Mob, we're honored to be the only US media outlet here to tell the tale.

2015 BMW X4 xDrive28i

When BMW unveiled the X6 back in 2008, critical reviews were mixed, to say the least. By all accounts, the heavyweight crossover actually drove quite well, but the idea of a BMW X5 that traded a lot of functionality for polarizing looks and a higher price tag seemed like a tough sell. Then it went on sale and quickly proved to be a cash cow. Today, the German brand has moved over a quarter million of the things worldwide. Unsurprisingly, this success has moved BMW to double down on its so-called Sport Activity Coupe by adding a smaller variant. The all-new X4, while not a bad steer in and of itself, makes even less sense than its big brother, particularly when viewed alongside BMW's other offerings. Like the X6 and X5, the X4 borrows heavily from another of the brand's utility vehicles, in this case, the less-costly X3. Also like the X6, this new crossover-coupe's styling is sure to cause a schism among critics and consumers alike. You can probably guess where the majority of the Autoblog camp falls. To be totally frank, the exterior of the X4 is simply ghastly to this writer, particularly in this tester's eye-catching paint. Admittedly – and much like the X6 – there's not much objectionable from the A-pillar forward, where the X4 has a lot in common with the X3. It's only once moving towards the rear that things well and truly go wrong. There's just so much visual mass, and it's been made worse by the way BMW designers wussed out. Bear with me. Compare the profile of the X6 with the X4, and pay particular attention to the roofline on the bigger vehicle. The angle of the roofline is noticeably more dramatic on the X6, which comes at the expense of second-row headroom (an oft-criticized area for the big boy). For the X4, designers tried to have their cake and eat it too, maintaining second-row headroom but with a coupe-like profile. The result is an X4 that is bulbous and uncouth from the B-pillar back, more hunchbacked Gran Turismo than svelte Gran Coupe. BMW might have been better served if its exterior work had followed the stylings of the cabin, which is more or less a clone of what's on offer in the X3. Material quality is still great, with soft-touch plastics and available cool-to-the-touch brushed aluminum throughout. I really dug the Ivory White Nevada leather and contrast red stitching on this test vehicle, as it provided an eye-pleasing departure from the sea of blacks, grays and tans so typical of the luxury crossover market.
