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:

Land Rover Defender V8, next Range Rover, new BMW M3 share the Nurburgring

From open-track days to 24-hour races, so many events are held on Germany's Nurburgring track that carmakers need to share the tarmac with their rivals to put new models through their paces. Industry pool days are normally closed to the public, but a seven-minute video reveals what Land Rover, BMW, and several others are testing. Posted on YouTube by StatesideSupercars, the video shows prototypes racing around the track in the mid-summer heat. Land Rover's engineers are busy putting the final touches on the V8-powered variant of the new Defender, which our spies have previously spotted testing in its home country of England, and they're developing what looks like the high-performance, SVR-badged version of the next-generation Range Rover due out in 2020. As we reported earlier in 2020, the hot-rodded Defender packs a 5.0-liter V8 between its fenders, though its horsepower and torque outputs remain under wraps. Unverified rumors claim it will arrive as a limited-edition model to avoid sending Land Rover's fleet-wide CO2 emissions through the roof. And, the video confirms chassis engineers have made extensive modifications to the SUV's suspension, partly to keep body roll in check. Walking down the pits, members of BMW's testing team are getting up early to put track miles on an enigmatic variant of the face-lifted M5, and on the next-generation M3. We've already seen the M5 in the metal, so why is it still camouflaged? One possible answer is that we're looking at the rumored CS version, which should receive a 641-horsepower V8 thanks to software tweaks and a better cooling system. The simpler (and more boring) possibility is that BMW isn't quite done testing the M5, and it doesn't want to waste time removing the black and white wrap. Your author regularly spotted i8 prototypes in full camouflage regalia months after its debut. As for the M3, much has already been said about its mammoth grille, which seemingly mirrors the one worn by the new 4 Series. Autoblog drove a pre-production prototype in June and walked away impressed. It receives an evolution of the X3 M's 3.0-liter straight-six turbocharged to 473 horsepower, though selecting the optional Competition package will increase that figure to 503. And, fear not: The six-speed stick is coming back. Land Rover and BMW aren't the only companies playing on the 'Ring.

BMW X3 spied with nip and tuck nearly complete

With the style-driven BMW X4 coming along in development, it looks like some of the forthcoming crossover's design could trickle over to its utilitarian sibling, the X3. Captured in these spy shots, it appears that the 2015 BMW X3 is preparing for a minor facelift, and from what we can tell, the biggest change will center on the CUV's headlights.
There is plenty of camouflage on the front and rear fascias to suggest updates will occur there, too, but we can definitely tell that the X3 will be getting LED-equipped headlights - at least as an option, anyway. The halos are slightly different from the current offering and there is also an LED strip above the headlights used as turn signal indicators. Another interesting thing we notice in these pictures is the nub at the bottom of the grille (also visible in recent X4 spy shots). While this could be some sort of test sensor for this prototype, it could also be a front-mounted camera for a possible parking assist system.
We don't expect any changes to the powertrain and we're not sure what updates could be in store for the interior, but we're guessing that that the 2015 X3 will debut shortly after the X4 goes on sale next year.
