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 X4 reclaims dash of utility with Clemson student project [w/videos]

BMW seems willing to exploit every automotive niche it can find with creations like the four-door, 'crossover coupe' X4 and X6. Of course, these designs come with a compromise. That svelte fastback means that they just can't haul as much cargo as a more traditional, boxier hatchback. Fortunately, students at Clemson University's International Center for Automotive Research might have a novel solution: the engineering graduate program has turned the crossover into a unique pickup.
Dubbed Deep Orange 4 concept, this functional prototype has an enclosed cargo area with a sliding glass panel that opens up to expose a pickup bed if more room is needed. Think of it as the GMC Envoy XUV of German crossovers. This isn't just an X4 with its roof hacked off, though. The students actually started with an X3 and grafted on this top later in addition to the two barn doors for access to the bed.
To make this project even more impressive, this pickup-crossover could conceivably be produced. The graduate students conducted an in-plant analysis of BMW's manufacturing abilities and went back to the university to create a plan for a low-volume vehicle that could actually be built. "The students working on this phase of the project did an excellent job of keeping costs down while finding optimal integration opportunities," said Rich Morris, vice president of assembly at BMW Manufacturing, in the university's release.

The 570-hp AC Schnitzer ACL2 Concept tries to one-up the M2

AC Schnitzer's new ACL2 concept aims to outdo the BMW M2 at the Geneva Motor Show. To out-muscle the latest M car, the German tuner starts with an M235i and installs the M4's 3.0-liter inline-six. The company also turns up the power to 570 horsepower – a healthy upgrade over 365 hp from the M2's 3.0-liter. The power bump lets the ACL2 reach 62 miles per hour in 3.9 seconds and hit a top speed of 205 miles per hour, AC Schnitzer claims. Those figures make the coupe a few tenths quicker than the M2's 4.2-second to 60 mph sprint, but BMW limits its creation to 155 mph. AC Schnitzer's long list of upgrades makes the impressive performance possible. To get the most out of the engine, the company installs a carbon fiber intake. It also replaces the most of the exhaust, including the downpipe, catalytic converter and tailpipes. Carbon-ceramic brake discs make sure a driver can control so much power, and the company fits a fully adjustable suspension to aid handling. The ACL2's body is too loud for our tastes even through the subdued dark green paint, but the extensive use of carbon fiber parts should keep weight down. AC Schnitzer adds a road-scraping front splitter with canards at each corner. The rear has a similarly aggressive diffuser and huge wing. The wider fenders also add 5.5 inches to the coupe's width, and 20-inch wheels sit underneath them. The ACL2 doesn't get to challenge the M2 on the Autobahn yet because AC Schnitzer says it's just a concept. The coupe exists simply for the company's product development. However, if you want to put all of these bits together, the final cost would be 149,000 euros ($161,500 at current exchange rates), the tuner claims. Related Video:
