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 Rocketman back on the table, might go aluminum

Mini just doesn't want its Rocketman concept to die. It unveiled the truly mini model at the 2011 Geneva Motor Show, and since then, there have been countless on-again, off-again rumors about the possibility of it going into production. If the latest talk proves true, a smaller vehicle like the Rocketman might make it into the automaker's lineup after all, as competitor to other stylish city cars like the Smart ForTwo.
According to the company's head of design, Anders Warming, speaking to Auto Express, Mini likes the idea of having a smaller model in its lineup, but it has to figure out a way of actually making it work. Warming is clear that the next iteration of the Rocketman concept (or whatever it's called then) won't be seen until a design is ready.
There are still plenty of challenges keeping a production Rocketman off of the city streets of the world, and chief among them continues to be finding a platform. But Mini is at least considering it. "At the moment, we don't have the right tech solutions, but we are working on it. We don't yet have a final solution, you could say," said Warming to Auto Express. He also thinks the final version would drop the concept's carbon fiber in favor of more aluminum components.

Mini lineup could expand to include up to 10 models, still no hope for Rocketman

During an event in Ponce, Puerto Rico last week where Mini introduced members of the media to the 2013 Paceman and John Cooper Works GP, product planners discussed that the brand's lineup could expand to eventually include up to 10 bodystyles. Currently, the Mini range consists of seven models: the Hardtop, Clubman, Convertible, Countryman, Coupe, Roadster and Paceman.
Speaking to members of the media, David Duncan, Mini USA sales manager, said that these new models could fall into a range of niches - "any segment that makes sense for a small car." No specific vehicle classes were discussed, but Duncan stated that the possibilities are endless, "as long as we're the smallest player in any segment."
Well, nearly endless. We've been hoping that Mini would re-think its decision to nix plans to create a vehicle smaller than the Hardtop - a notion previewed by the excellent Rocketman concept (shown above) from the 2011 Geneva Motor Show - but the automaker once again stated that this is absolutely off the table. In order to create a vehicle of the Rocketman's size, a completely new platform would have to be engineered (that's expensive), and while Mini has looked into acquiring existing architecture from another brand, parent company BMW has reportedly put the kibosh on such an act. If a Rocketman is ever to be born, BMW/Mini will do it on its own, and right now, that simply isn't in the cards.
