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:

Daily Driver: 2015 BMW X6 M

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, featuring impressions from the staffers that drive them every day. Today's Daily Driver features the 2015 BMW X6 M, reviewed by Greg Migliore. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT: [00:00:00] Hey, everybody. It's Greg Migliore, and today I am driving the 2015 BMW X6 M. This is the crossover coupe that is sort of a halo SUV for BMW. It's got its naysayers but I like it. I think it's a number of things enthusiasts like. It's fast, it's curvy, it looks good, it's fun to drive, and this one that I'm [00:00:30] testing out is absolutely loaded. It comes in at more than $115,000. Now that might seem like a lot for an X6, even in M trim, but you're getting a lot of stuff here. This has got a twin-turbo V8, pumps out 567 horsepower. It's mated to an eight-speed automatic transmission, which I think is a good one, and it runs with all-wheel drive. There's a number of M treatments like the wheels, some of the aerodynamic treatments up front. [00:01:00] It looks sporty and it also has a good tough crossover feel, but it still has almost a car feel as well because the X6 was designed to have a bit of a coupe dynamic. Now inside, is really a beautiful surroundings. We've got lots of trim. It looks like carbon fiber. We've got different color stitching. There's black trim, there's orange trim, there is some of the M colors of light blue and red trim on the steering wheel. It definitely looks like a [00:01:30] loaded BMW, but also an M BMW series. You lay on the throttle you can get away from stoplights quickly, no trouble. Sounds good. There's a nice exhaust note. It got moving. It's a quick car. It can get to 60 miles an hour in about four seconds, which when you consider this SUV is above 5,200 pounds, that's pretty quick. Some people question the point of an X6 in general, [00:02:00] and especially an X6 M. You're taking an SUV with less capability than an X5 and some other SUVs in this segment and then cutting it down and making a design statement. I say exactly. That's exactly what you're doing. I like a vehicle that looks like this that has those coupe-like stylings in the back. It's a little more of a cutting edge, curvy design. I think all of that's great. Then, if you're going to do different M versions of cars, why not do an X6 M?

New BMW i3-like Visio.M EV concept uses lightweight resin

It's not a new version of the BMW i3, but an updated version of a lightweight concept car from SABIC, BMW, the Technical University of Munich, Daimler and others does bear a certain resemblance to the well-designed plug-in city car. From the black "glass" in the hatch to the angled line tail lights to the up-and-down window line, you can see a sort of family resemblance (see an i3 comparison photo here). And, of course, they both have an electric powertrain. But the changes made to the new lightweight urban electric concept vehicle is more of an exercise in what's possible rather than a way to evolve the i3 and i8 into a broader i family of vehicles. Even so, what we see here is interesting, since SABIC found all sorts of new ways to take weight out of the car as part of the Visio.M (Visionary Mobility) project, which was first announced in 2012. Let's start with the window material, which as you might guess from the quotation marks above, is not made of glass but is instead SABIC's Lexan polycarbonate (PC) resin plastic. The lower weight (the PC helps shed about 29 pounds) adds two miles of range while the PC resin has better thermal conductivity compared to glass and so does even more because the HVAC system can be more efficient. According to SABIC's computational fluid dynamics analysis, an extra 9-10 miles of range, in fact. Without the battery, this concept weighs just 992 pounds. Remember, BMW already made a lot of weight-reduction measures in the i3 thanks to carbon fiber reinforced plastic, so to make the "glass" lighter would only help boost efficiencies on a production vehicle that uses a resin like this. Read more below. SABIC's LEXAN™ resin delivers weight savings and thermal efficiency for new ultra-lightweight electric car concept developed by BMW-led Visio.M Consortium Munich, October 20, 2014 Today, at the Technical University of Munich (TUM), BMW, Daimler, TUM scientists and a consortium of industry participants showcased a lightweight urban electric concept vehicle with various advances, including an all-plastic design of the car's windows. The windows are made of LEXAN resin, a polycarbonate (PC) material, and coating technologies from SABIC, a leading developer of PC glazing for automotive windows and many other thermoplastic solutions for the automotive industry.
