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:

Mini Superleggera patent renderings suggest production prospects

Mini impressed us all when it revealed the Superleggera Vision concept at the Paris Motor Show a couple of months ago. But even before the little roadster concept debuted, there were already rumors of its production potential. And those rumors are only being further entrenched by the emergence of a series of patent renderings. Bearing much more than a passing resemblance to the concept, these images show what could be a revised, production version of the Superleggera, though not without its concessions to reality. For one thing, it looks like it's got a proper framed windshield, but it's hard to tell with the roof in place – something we never saw on the concept, either. It's also got more substantial wing mirrors, but the fin on the rear deck is still there, as are the extractor vents on the hood. We also note that the grille openings are the same shape as the concept's. Of course, the emergence of these images and their filing with the relevant authorities doesn't necessarily mean that Mini is moving ahead with the roadster's production. But if it did, it would likely ditch the concept's electric powertrain, and could stand to fill the void left by the discontinuation of the maligned, outgoing Mini Roadster that was essentially a scrunched Cabriolet with a cowling where the rear seats and stacked roof would be. Parent company BMW is likely taking into account that its rival Daimler didn't have much luck when it slotted a unique roadster of its own into the Smart lineup, so here's hoping that if it does give the Superleggera the green light, it'll have more success in the marketplace.

Mini Multitone Edition brings triple-color roof to more models

Last year's refreshed Mini line-up introduced the "Multitone" roof for the Mini Cooper SE. It featured three paint colors on the roof that faded into one another. Now that option is available on many more Minis with the Multitone Edition, which also picks up a unique design and trim pieces to accent the fancy top. The Multitone Edition is available on all Mini 3-Door and 5-Door Hardtops as well as the Clubman wagon. The Hardtops are only offered in "Sage Green" while the Clubman only comes in "Indian Summer Red." All of them get a Multitone roof in white, silver and black (the blue and red options from the SE seem to remain exclusive to the little electric hatch). Setting this grayscale roof apart is a set of perpendicular "rainbow" stripes done in a satin clearcoat. This motif is continued around the car where it appears in the two-tone green and red badging on the wheels and fender "scuttles." It also appears on the dashboard and other interior trim. And on the topic of trim, parts that were chrome on regular Mini models are a bright gloss white such as the light surrounds, door handles and fuel filler cap on S models. Two-tone alloy wheels are offered in 17- and 18-inch sizes. Pricing and availability haven't been announced yet. Expect to see the option available sometime this year, and a small premium over whatever trim level it's added to. Related Video: This content is hosted by a third party.
