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 Z4 and Toyota Supra replacement spied in the snow

The new BMW Z4 and Toyota Supra will be the fruit of a marriage of convenience, born from the former's chassis and powertrain expertise and the latter's giant coffers full of money. The final product, spied testing in frigid temperatures in parts unknown, will have specific bodies depending on which brand it carries, so it won't be a simple rebadging exercise. This mule sports a softtop, rather than a retractable hardtop like the existing Z4. Whether this represents a final decision about what type of roof will be fitted to the production model is unclear. What we have heard, repeatedly, is that the chassis and the entire driveline will be pure BMW for both models, and that the main difference will be brand-specific sheetmetal. There are even rumors that an all-wheel-drive version will be available, or that the model will be available as a hybrid using Toyota's expertise in that arena. It's been a long wait since the memorandum of understanding that lead to the mule you see above was signed in 2012, and we had expected an announcement that the roadster would go into production by the end of 2015, but that time has come and gone. Perhaps we'll find out more at one of the upcoming auto shows. Geneva is coming up in March, after all.

Recharge Wrap-up: video touts Volvo electric buses, Nissan and BMW build EV chargers in S. Africa

Volvo is touting the advantages of electric buses in a new video. The short film, called Route 55, promotes the ElectriCity Project for public transport, and, more specifically, the new electric bus route in Gothenburg, Sweden. The new route debuts June 15 using Volvo electric and hybrid buses. In the video, two teenagers are seen waiting for the bus. As one boards, the other asks her out from the sidewalk, but she can't hear him over the noise of the diesel bus, which then closes its doors and drives away. The film asks, "What if this bus had been silent?" See the video above, and read more in the press release below. BMW and Nissan will build an EV charging network across South Africa. Through 2017, the two automakers will build fast-charging and AC stations around the country in order to encourage the adoption of EVs. Nissan has been selling the Leaf in South Africa since 2013, and BMW introduced the i3 and i8 in March. "In order for the introduction and expansion of electric vehicles as well as plug-in hybrid electric vehicles to be successful in this market, we need to work together," says BMW South Africa Managing Director Tim Abbott.

The fleet of vehicles includes the Nissan Leaf and e-NV200, as well as the Renault ZOE, Kangoo ZE and Fluence ZE. The entire passenger car shuttle fleet will use all-electric vehicles as some 20,000 UN attendees descend upon Paris from November 30 to December 11. "Thanks to the Alliance's fleet of 100-percent electric vehicles, it will contribute to our goal of achieving a carbon neutral event," says French Minister of Foreign Affairs and International Development and COP21 President Laurent Fabius. "The technology of electric vehicles helps reduce greenhouse gases in the transportation sector efficiently." Read more from Renault. Visa will be the official title sponsor of the Formula E London ePrix. Officially called the "2015 FIA Formula E Visa London ePrix," the races on June 27 and 28 will be the last of the electric racing series's inaugural season. Visa Europe will award the Visa Fastest Lap trophy after the each round, and will have interactive activities at the race's eVillage.
