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 i3 to be priced around $40,000

According to Automotive News, the BMW i3 electric hatchback will likely be priced around $40,000, or similar to that of a well-equipped 3 Series sedan, when it goes on sale later this year. This information was revealed during an interview where AN spoke to Ludwig Willisch, CEO of BMW North America. The i3 will likely qualify for a $7,500 tax credit from the US federal government, though AN reports that a BMW spokesperson could not confirm this just yet.
In addition to the all-electric i3, BMW will offer a range-extended version that uses a 0.65-liter two-cylinder motorcycle engine and auxiliary generator to charge the car's battery on the go. Automotive News says pricing for this model is still unclear, as is whether or not the range-extended i3 will be eligible for the $7,500 tax credit. Of course, buyers needing a vehicle for longer trips will be able to borrow one from the automaker.
Automotive News also reports that the majority of BMW's 338 dealers in the United States will be able to sell the i3, as well as the upcoming i8 hybrid sports car. Dealerships have until June of this year to opt out of this program, however.

McLaren shoehorned the F1's V12 into a BMW M5 wagon test mule

Automakers are known to utilize preexisting vehicles as test beds for major research and development purposes. But some of the zombie mashups produced in-house can result in pretty interesting combinations. Case in point, when McLaren was developing its BMW-sourced naturally-aspirated 6.1-liter V12 for the legendary F1, the company put the engine in … a BMW M5 wagon? Yup, you read that correctly. ItÂ’s no mystery that the legendary F1 came with a BMW-sourced V12. That "M70" V12 originated from its placement in the E32 7 Series and E31 8 Series “50” models in the 1980s up through the 1990s. The version that went into the F1, however, is more closely related to the M-tuned "S70" V12 found in the E31 850CSI, which was the pseudo M-variant to the 8 Series that wasnÂ’t officially designated an M model. But it did feature full-fledged tuning from the M Division. On "Top Gear" presenter Chris HarrisÂ’ podcast, "Collecting Cars", Harris interviewed David Clark, the former director of McLarenÂ’s cars for both the road and motorsports between 1994 and 1998. Clark revealed that they took an E34 BMW M5 wagon and shoehorned the S70 V12 into its engine bay as the mule for testing the F1Â’s engine. Clark even said he drove the car himself as they were fine-tuning the V12Â’s engine output. YouÂ’re probably wondering, how the heck did that thing fit? But it isnÂ’t that surprising. The E34 5-Series was designed to house either the BMWÂ’s venerable straight-six or the new-at-the-time V8. And there was room enough to house the V12 as well, particularly since BMWÂ’s V12 was essentially two of its “M20” straight-sixes bolted together at the crank in a vee. When Clark was testing the S70 V12 in the wagon, he and his team ended up with the 627 horsepower and 479 pound-feet of torque the F1 became known for. ThatÂ’s nearly twice the power the production M5's 311 hp and 266 lb-ft at the time. Clark also divulged that the actual prototype mule still exists, but itÂ’s in BMWÂ’s secret collection of prototypes, and itÂ’s never been revealed to the public. He does, however, hope that one day, BMW will open its doors and show off the incredible mashup of an automobile. Until then, youÂ’ll have to rely on the few custom engine swaps done by owners to get a taste of what a V12-powered E34 M5 is like. Rumor also has it that McLaren could be working on a new direct F1 successor with help once again from Gordon Murray.
