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 M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.
