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:

2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.

2015 BMW i8 offers you a fast ride to the future for $135,700* [w/video]

BMW's long-form teasing and rollout of its incredibly cool i8 has put us in a unique position to report from its world debut here in Frankfurt. Typically, an auto show debut marks just the start of the information dump about a new vehicle. The i8, however, is a car that we've already driven and reviewed, so perhaps the biggest news from the show floor is the official price of the thing, as well as getting to see it live and in person, of course.
Arriving in US showrooms in the spring of 2014, the i8 performance plug-in hybrid will carry a price tag of $135,700 (*not including $925 for destination and handling charges). That kind of cash puts the i8 near the very top of the BMW range (slotting just under the top-trim 7-Series models), and will buy a massive amount of new technology.
The four-seat i8 has the look of a true supercar, and its new-tech drivetrain will offer up the performance of a stirring sports car, at least. A TwinPower Turbo, three-cylinder, 1.5-liter engine will make 231 horsepower and 236 pound-feet of torque that's gets sent to the rear wheels, while a 96-kilowatt electric motor doles out 131 hp and 184 lb-ft of maximum torque to the fronts. Total system output of 362 hp and 420 lb-ft allows the i8 to sprint to 62 miles per hour in 4.4 seconds with all-wheels-driven handling, and it still returns an astonishing 94 miles per gallon US.
