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 teases new 7 Series with gesture control tech, LCD display key

Want an early glimpse at what features you can expect to see in your next car a few years down the line? Look to flagship luxury sedans, where automakers often roll out their most advanced technologies. Like on the next-generation BMW 7 Series. Previewed in this teaser clip above, detailed in the press release below and pictured in the massive gallery at bottom, Munich's upcoming flagship model will be packed with innovative features. It'll have a remote-control parking feature that won't even require the driver to be on board when entering or exiting a parking space, controlled through an LCD touchscreen on the key fob. Once on board, you'll also be able to control the infotainment system with three-dimensional gestures made in the air or through the touchscreen display. Power will be provided by a new generation of engines, starting with a turbocharged inline-six mated to an eight-speed automatic transmission. An adaptive air suspension promises to offer a sporty or cushioning ride as desired. And it's all being built around a structure made partially out of carbon fiber, cutting nearly 290 pounds off the curb weight. All of which paints a picture of the next-generation 7 Series as a rolling technology exhibit, and one we're looking forward to experiencing first-hand. Technology and innovation workshop on the new BMW 7 Series model range. PreDrive Miramas. 17.04.2015 BMW is using a technology and innovation workshop to present an initial selection of development highlights which the next generation of the BMW 7 Series model range will use to set new benchmarks in lightweight design, driving dynamics, comfort, intelligent connectivity and operation. The extensive use of carbon-fibre-reinforced plastic (CFRP) in the structure of the passenger cell, the rigorous and detailed application of lightweight design and a new generation of engines combine to reduce the weight of the luxury sedan along with its fuel consumption and emissions figures. The comfort, safety and driving experience offered by the new BMW 7 Series benefit from new chassis technology, exceptional scope for interaction with the car's infotainment technology and a wider selection of driver assistance systems from BMW ConnectedDrive. BMW EfficientLightweight: Carbon Core helps to reduce weight by up to 130 kilograms. Thanks to the BMW EfficientLightweight strategy, the new BMW 7 Series line-up will tip the scales up to 130 kilograms lighter than the outgoing generation of models.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.
