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:

Jay Leno puts focus on some retro-inspired BMW bikes

Jay Leno puts eight wheels on display this week for Jay Leno's Garage from a quartet of retro-inspired BMW motorcycles. They are the creations of husband and wife team Larry and Carol Romestant, who build each one in their home garage.
Larry is a former aerospace engineer who loves BMW bikes, especially the K models. Now, he's combining his passion with a real talent for fabrication to build his own cycles with his wife. With Larry and Carol the only ones working on these projects, it takes them six to nine months to build each one. In addition to the old-school looks, the motorcycles are supposed to be a bit more user friendly than stock. For example, one of them ditches the standard five-speed gearbox in favor of a six-speed unit to be a little more comfy when cruising at high speeds.
Since there isn't enough time to take all four of them for a ride, Jay picks his favorite to test out on the open road. Scroll down to see which one he chooses.

BMW and Jaguar Land Rover to jointly develop electric car tech

FRANKFURT – BMW and Jaguar Land Rover on Wednesday said they will jointly develop electric motors, transmissions and power electronics, unveiling yet another industry alliance designed to lower the costs of developing electric cars. Both carmakers are under pressure to roll out zero-emission vehicles to meet stringent anti-pollution rules, but have struggled to maintain profit margins faced with the rising costs of making electric, connected and autonomous cars. "Together, we have the opportunity to cater more effectively for customer needs by shortening development time and bringing vehicles and state-of-the-art technologies more rapidly to market," said BMW board member Klaus Froehlich. BMW and Jaguar Land Rover said they will save costs through shared development, production planning and joint purchasing of electric car components. Both companies will produce electric drivetrains in their own manufacturing facilities, BMW said. The BMW Jaguar Land Rover pact comes as rivals FiatChrysler and Renault explore a $35 billion tie-up of the Italian-American and French carmaking groups. Nick Rogers, Jaguar Land Rover's engineering director said, "We've proven we can build world beating electric cars but now we need to scale the technology to support the next generation of Jaguar and Land Rover products." BMW was in talks with rival Daimler about developing electric car components but was also in discussions with Jaguar Land Rover, a company it once owned, to explore an alliance on engines. BMW already has a deal to supply an 8 cylinder engine to Jaguar Land Rover. Carmakers are increasingly open to sharing electric car parts because the technology is expensive and because customers no longer buy a car based on what engine a vehicle has. "Carmakers are much less precious about sharing electric car technology because it is much harder to create product differentiation with electric car tech. They all accelerate fast, and everybody can do quality and ride and handling," according to Carl-Peter Forster a former chief executive of Tata Motors and a former BMW executive. Jaguar Land Rover is still run by former BMW managers, including Ralf Speth the company's chief executive who spent 20 years at BMW prior to joining JLR, and Wolfgang Ziebart, the engineer who oversaw Jaguar's I-Pace electric car program, who is a former head of research and development at BMW.
