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:

BMW plugs in new X5 xDrive40e PHEV crossover

BMW broke with its own convention when it rolled out the original X5 back in 1999, and did it again when it launched the i3 and i8 plug-in hybrids in 2013. Now it's bringing the two together with the reveal of the new X5 xDrive40e. Based on the third-generation F15 model and previewed by the X5 eDrive concept at the 2013 Frankfurt Motor Show, the X5 xDrive40e is the first PHEV from the core BMW brand. Its hybrid powertrain pairs a 2.0-liter turbo four (itself good for 245 horsepower and 258 pound-feet of torque) to an electric motor integrated into the eight-speed automatic transmission (contributing another 113 hp and 184 lb-ft) for a total combined output of 313 hp and 332 lb-ft. That makes it more powerful by both counts than the six-cylinder X5 xDrive35i (though considerably less so than the V8-powered xDrive50i), giving it a quoted 0-62 time of 6.8 seconds and an electronically limited top speed of 130 mph. But it can travel up to 19 miles on electric power alone, at which top speed is limited to 75 mph. BMW has mounted the 9-kWh lithium-ion battery pack underneath the luggage floor, limiting cargo capacity to between 17.65 and 60.7 cubic feet, depending on how you set up the rear seats. An adaptive suspension keeps it all on an even keel, with power transmitted to all four wheels through a permanent all-wheel-drive system. An M model it is not, but the Bavarian automaker will offer it with an M Sport package. Full details on pricing and availability have yet to be announced, but the X5 xDrive40e is set to hit European dealers in the fall. The BMW X5 xDrive40e The first plug-in hybrid production car from the BMW core brand is a Sports Activity Vehicle. Permanent all-wheel drive and the BMW EfficientDynamics eDrive technology endow the BMW X5 xDrive40e with sensational sportiness and supreme poise on the one hand and outstanding efficiency on the other. With a total system output of 230 kW/313 hp generated by a four-cylinder petrol engine with BMW TwinPower Turbo technology and a synchronous electric motor, the BMW X5 xDrive40e achieves a combined fuel consumption of 3.4 – 3.3 litres per 100 kilometres (83.1 – 85.6 mpg imp) and a combined electricity consumption of 15.4 – 15.3 kWh over the same distance. CO2 emissions come in at 78 – 77 grams per kilometre (figures according to EU test cycle for plug-in hybrid vehicles, may vary depending on the tyre format specified).

The List: Best of proving grounds

Proving grounds are where automakers and enthusiasts alike go to push their vehicles to their mechanical limits. The Rubicon Trail, located in the Sierra Nevada, is the ultimate off-road test, while Germany's Nurburgring is a grueling 13 mile road and track course. Jessi and Patrick visit both iconic proving grounds in this "best of" compilation of The List.
