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 preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

BMW celebrates 30 years of M5 with 600-hp super sedan

It's been 30 years since BMW rolled out the first M5, and while displacement and cylinder count may have fluctuated over those past three decades, output has only increased. The first-generation E28 M5 packed a 3.5-liter inline-six with 252 horsepower and 243 lb-ft of torque. The second-gen E34 model that followed added an extra 100 cc (and later 200 more) to produce 310 hp and 266 lb-ft. The E39 followed with a 4.9-liter V8 churning out 394 hp and 369 lb-ft, replaced by the award-winning 5.0-liter V10 in the E60 with its 500 hp and 380 lb-ft before BMW rolled out the latest model with a 4.4-liter V8, its twin turbos making up for the two dropped cylinders and 600 cc of displacement to produce 560 hp and 502 lb-ft of torque. But even that's being left in the dust by the new special edition you see here.
The 30th Anniversary Edition BMW M5 packs that same 4.4-liter twin-turbo V8, but cranks the output up to a nice, round 600 horsepower and a solid 516 lb-ft of torque to go with it. That makes it more powerful, not only than any M5 that's come before it, but also any of its rivals. The Jaguar XFR-S and Audi RS6 Avant (the latter only available as a wagon and not in North America) both lag behind this ultimate of Ultimate Driving Machines; only the Mercedes-Benz E63 AMG trumps it on torque (but not on power), with 531 lb-ft in stock form and 590 in the S-Model.
As a result, the 0-60 time drops from a quoted 4.2 seconds in the stock M5 to a scant 3.7 in the 30th Anniversary edition (just one tick behind that twistier E63 S). The special M5 also comes with the Competition Package as standard, as well as a dedicated control module for the Active M Differential, a special Frozen Dark Silver matte finish, 20-inch alloys and black chrome badges. Special badges abound inside as well, where you'll also find black leather and Alcantara upholstery and aluminum trim. There'll even be a dedicated one-day course offered to owners at The Thermal Club in Palm Springs, CA, to further sweeten the deal.
