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 M2, we're happy to see you

I recently spent some time behind the wheel of the BMW M235i and, well, I didn't love it. Sure, it's a great car, but I just didn't truly bond with it the way I have with previous M cars. What I had hoped for was a proper successor to the 1 Series M Coupe I fell in love with in 2011, but what I got instead was just a sporty 2 Series that didn't exactly stir my emotions in the same way.
But now there's this: the honest-to-goodness BMW M2. Previously, spy photographers captured a development-mule M2, but this is the real thing, in its full prototype body. Notice the aggressive front fascia that mimics the M3/M4, the more more robust wheel/tire package, and the M-standard quad exhaust outlets around back. This thing sure does look the business.
Details are slim as of this writing, but rumors suggest power will come from BMW's now-ubiquitous N55 turbocharged 3.0-liter six, with output somewhere in the 360- to 380-horspower range. The seven-speed M dual-clutch transmission seems like a good fit here, too. As does a six-speed manual transmission (here's hoping).

This insane Barris-like custom car is a backyard BMW Z3 build

This is the second car made by Englishman Paul Bacon and it's called the Cosmotron, fashioned over 18 months in his backyard shed. Underneath that Jetsons bubble canopy and swinging-sixties body are the bones of a 1998 BMW Z3 with a 2.8-liter inline-six. Bacon stripped the roadster down, then built it back up using fiberglass laid over polystyrene foam, and leather hand-stitched by his wife. Bacon said he remembers how we were told that 21st-century cars would look like the Cosmotron, and since they don't, he had to fix the error. The list of 20th-century add-ons, however, is impressive, like the six SU carburetors topped off with department-store salt and pepper shakers, and the rear grille decorated with shiny plastic tops from moisturizer bottles. After driving the Cosmotron for two years, Bacon sold it to get ready for his third project. You can hear Bacon and the new buyer tell their stories in the video above.
