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:

Evo pits BMW M3 against Porsche Macan in drag battle

If you want to move five passengers in very rapid fashion and you've got a $75,000 budget, two newly introduced four-door models immediately come to mind - both are the highest performing vehicles in their respective segments. But which is faster off the line, to the 60-mile-per-hour benchmark or flat-out over an even longer run? Evo took both to paved aircraft runway to find out.
In lane one we've got the all-new Porsche Macan Turbo, which boasts a twin-turbocharged, 3.6-liter V6 rated at 400 horsepower and 406 pound-feet of torque. The Porsche is fitted with a seven-speed, dual-clutch gearbox, and the 4,244-pound crossover has the traction advantage of standard all-wheel drive. In lane two is the all-new BMW M3, powered by a twin-turbo 3.0-liter inline-six rated at 425 horsepower and 406 pound-feet of torque. It is also equipped with a seven-speed, dual-clutch gearbox, but only the rear wheels of the 3,595-pound sedan are driven. Both the BMW and Porsche arrive with launch control, which helps to remove driver error off the line.
Which automaker's launch control system is better off the line? Does all-wheel-drive grip give the crossover the advantage it needs to overcome its adversary's power-to-weight advantage? Will aerodynamics factor into the results? Which would you put in your garage, and why? The video may surprise you.

BMW to announce location of new plant in Mexico in July

Volkswagen manufactures in Mexico. Soon Audi will as well, and Mercedes-Benz is said to be working on a deal to assemble some of its cars at a Nissan plant in Mexico too. That leaves BMW out of the mix of German automakers building cars South of the Border, but that may soon be rectified, as well.
According to Automotive News, the Bavarian automaker is preparing to announce the site of its first Mexican assembly plant as soon as July, now just two months away. BMW already builds cars for North American consumption at its plant in Spartanburg, South Carolina, but has reportedly been keen to capitalize on cheaper labor and the benefits of the North American Free Trade Agreement to supply vehicles to the United States and Canada especially.
When BMW does announce the site of the plant - reportedly narrowed down to either Hidalgo or San Luis Potosi - it is tipped to work its way up to 100,000 vehicles per year at the new location, potentially to include the 3 Series as well as smaller, front-drive models, including Minis.
