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.

BMW's EV tech is being used to resurrect the Karma

Saying that luxury electric-vehicle manufacturer Fisker was beleaguered before its demise a few years back would be a gross understatement. But despite the cars self-immolating and Tesla CEO Elon Musk criticizing everything but the Karma's design, a Chinese auto parts manufacturer is resurrecting the brand under a different name: "Revero." That's according to a report from Wall Street Journal. Wanxiang Group is moving production to EV-hotbed California from Finland and will unveil its new ride either in July or August, but pricing hasn't been announced yet. The previous Karma sold for $100,000. Perhaps most interesting, though, is how it's going to address the reliability issues that plagued the company's predecessor. WSJ says that the automaker is licensing BMW's electric vehicle control and charging systems – a deal finalized last year. "There are huge, serious, major upgrades throughout the electronics systems, wiring, charging, battery," Karma's chief marketing officer Jim Taylor says. In terms of looks, though, it doesn't sound like you should expect anything to change in that department because the overhauls aren't going to be visible, according to Taylor. Wanxiang picked up Fisker's remains for $149 million a few years back. This deal is important, especially for BMW: If the German automaker's licensed tech can help Fisker outrun its smoky, checkered past, that's a high-profile win for everyone involved.

BMW previews new M6 GT3 racing prototype [UPDATE]

UPDATE: A previous version of this post specified the incorrect weight target for the M6 GT3. The text below has been updated with the correct information. BMW may not compete at the top level at Le Mans or in the World Rally Championship, it may have withdrawn from Formula One and shuttered the Formula BMW series, but it's not without its racing programs. Aside from the Minis that dominate the Dakar Rally, BMW fields the M4 in DTM, the M235i Racing in the BMW Sports Trophy and the Z4 in GT3 competitions around the world. But now it's preparing to launch a new GT3 racer based on the M6. Currently undergoing development, BMW has presented its new M6 GT3 prototype at its factory in Dingolfing, Germany. Based on the road-going M6 coupe, the GT3 retains its 4.4-liter twin-turbo V8 engine with dry-sump lubrication, producing over 500 horsepower – which is actually less than the road-going model you can buy, but has to be restricted to meet FIA certification. At less than 3,000 pounds, it is a fair bit lighter than the production version, and promises to deliver blistering performance figures to whichever privateer teams buy one to enter in racing series around the world. The M6 GT3 is slated to hit the circuits next year, when it will join the lineup alongside the M6 coupe, M6 convertible and M6 Gran Coupe, to say nothing of the M6 safety car used in MotoGP. In a related development, BMW Blog reports that the Bavarian automaker is probing potential interest in bringing the M235i Racing to North America. The entry-level model in the BMW Motorsports range, the M235i Racing sells in Europe for the equivalent of $68,000. The next milestone: the BMW M6 GT3 is rolled out at the BMW premises in Dingolfing. 05.02.2015 Munich (DE), 5th February 2015. BMW's new figurehead for the GT racing scene has been given its first run: last Saturday, the test track on the premises of the BMW factory in Dingolfing (DE) provided the stage for the roll-out of the BMW M6 GT3, with which BMW teams will compete in national and international series, as well as at iconic endurance races, from 2016 onwards. The car left the garage for the first time at precisely 14:00 with Jorg Muller (DE) at the wheel. This gave the BMW works driver the honour of creating the next milestone in the development of the BMW M6 GT3. "This is a big moment for everyone who has worked so intensely and passionately on the development of the BMW M6 GT3 in recent months," said BMW Motorsport Director Jens Marquardt.
