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.

This is the BMW Z4 GTE that will wear the Roundel in ALMS

The Speedweeks at Daytona International Speedway are a month of racing and reveals, with the season's metal going for the flag at races like the Rolex 24 at Daytona and other cars being introduced to the public. In the latter category is the BMW Z4 GTE (click the image above to enlarge) joining the American Le Mans Series GT class this year with BMW Team RLL (Rahal, Letterman and Lanigan). This machine replaces the M3 GT that completed four years of service and won the class title in 2010 and 2011. Naturally, the team is tempering expectations for the Z4 GTE by repeating the fact that it sees this season as a development year.
BMW Team RLL drivers for its two cars will be Bill Auberlen and series rookie Maxime Martin in the No. 55, aided by Jörg Müller for the endurance races at Sebring and Road Atlanta. The No. 56 car gets Dirk Müller on a full-time basis, Joey Hand when he's not competing in the DTM series, and John Edwards when Hand isn't available. Uwe Alzen will help out with driving duties in the No. 56 at endurance races.

Translogic 189: 2015 LA Auto Show

The LA Auto Show has become known for its green cars and concepts, and 2015 was no exception. Translogic host Jonathon Buckley gets all the details on BMW's 330e plug-in hybrid straight from BMW President of North America Ludwig Willisch. Then we get up-to-date on Honda's latest FCX Clarity hydrogen fuel cell car. We round out our tour with a stop at the Elio Motors booth for a look at their updated, three-wheel P5 concept and a chat with CEO Paul Elio. But first, we jump in a time machine at the Volvo booth to discuss Concept 26, an interpretation of how car interiors might evolve in the era of self-driving cars. "The reason why we talked about it as a time machine [is] because, really, Concept 26 is giving you back something that is so precious," explained Volvo senior director of design Tisha Johnson. "We're letting you delegate driving to the car, so that you can then have that time to yourself." Click here to learn more about our host, Jonathon Buckley.
