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 exec says public chargers not important for EV success

What has BMW learned from years of electric vehicle test programs and working with Mini E drivers and the ActiveE Electronauts? According to BMW board member Herbert Diess, it's that public charging is not an important piece of the puzzle of making EVs a success. The way those early EV drivers used their vehicles told BMW that, "public infrastructure is not really very important because most people are charging their cars at home," Diess recently told Wards Auto. It's a message we've heard before. Diess' personal experience fits with this conclusion, he said. After driving his company's new i3 city EV for over a year, "not once have I touched public charging." Of course, the i3 does let the driver search for public charging stations and BMW has a partnership with ChargePoint, and Diess is not hinting that BMW is totally against the idea of public charging. Still, Diess' comments are not likely to find a warm welcome with everyone in the EV scene. An August 2012 UCLA study titled "Financial Viability Of Non-Residential Electric Vehicle Charging Stations" (PDF) clearly states: Adoption by consumers will largely be a function of the electric vehicle charging options available. Studies show that most EV charging currently takes place in the home (Carr 2010). Even so, in order for EVs to gain widespread consumer adoption, it is critical for an infrastructure of electric vehicle supply equipment (EVSEs) to exist outside the home. Even BMW's own electric drivers have been sending mixed messages. In 2010, a study of Mini E drivers found that 87.5 percent said a public charging infrastructure is necessary, though 75 percent later said they could manage without such a network.

Land Rover Defender V8, next Range Rover, new BMW M3 share the Nurburgring

From open-track days to 24-hour races, so many events are held on Germany's Nurburgring track that carmakers need to share the tarmac with their rivals to put new models through their paces. Industry pool days are normally closed to the public, but a seven-minute video reveals what Land Rover, BMW, and several others are testing. Posted on YouTube by StatesideSupercars, the video shows prototypes racing around the track in the mid-summer heat. Land Rover's engineers are busy putting the final touches on the V8-powered variant of the new Defender, which our spies have previously spotted testing in its home country of England, and they're developing what looks like the high-performance, SVR-badged version of the next-generation Range Rover due out in 2020. As we reported earlier in 2020, the hot-rodded Defender packs a 5.0-liter V8 between its fenders, though its horsepower and torque outputs remain under wraps. Unverified rumors claim it will arrive as a limited-edition model to avoid sending Land Rover's fleet-wide CO2 emissions through the roof. And, the video confirms chassis engineers have made extensive modifications to the SUV's suspension, partly to keep body roll in check. Walking down the pits, members of BMW's testing team are getting up early to put track miles on an enigmatic variant of the face-lifted M5, and on the next-generation M3. We've already seen the M5 in the metal, so why is it still camouflaged? One possible answer is that we're looking at the rumored CS version, which should receive a 641-horsepower V8 thanks to software tweaks and a better cooling system. The simpler (and more boring) possibility is that BMW isn't quite done testing the M5, and it doesn't want to waste time removing the black and white wrap. Your author regularly spotted i8 prototypes in full camouflage regalia months after its debut. As for the M3, much has already been said about its mammoth grille, which seemingly mirrors the one worn by the new 4 Series. Autoblog drove a pre-production prototype in June and walked away impressed. It receives an evolution of the X3 M's 3.0-liter straight-six turbocharged to 473 horsepower, though selecting the optional Competition package will increase that figure to 503. And, fear not: The six-speed stick is coming back. Land Rover and BMW aren't the only companies playing on the 'Ring.
