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.

Mercedes-Benz C-Class named 2015 World Car of the Year

It's been a good morning for Mercedes-Benz, with three of the company's wares taking home awards today at the New York Auto Show. The 2015 World Car of the Year awards have just been announced, and the charming new C-Class sedan has taken top honors, beating both the new Volkswagen Passat and Ford Mustang. But Car of the Year isn't the only award Mercedes received this morning. Here are the other World Car announcements, where M-B was honored two more times. World Performance Car of the Year: Mercedes-AMG GT World Luxury Car of the Year: Mercedes-Benz S-Class Coupe World Green Car of the Year: BMW i8 World Car Design of the Year: Citroen C4 Cactus Congratulations, all around, to this fantastic group of cars.

2014 BMW M5 facelift shows up online

Is it that time already? Like its predecessors, the current BMW M5 has been endangering US licenses since it first went on sale here in 2012, but its design became a known quantity back at the 2011 Frankfurt Motor Show. Apparently that also means that the F10 generation has already grown tired enough to the "Must Have Latest Set" who can afford these sorts of super saloons that a facelift is in order.
If these leaked images sourced from Autocar are anything to go by, BMW stylists have used a predictably light hand to rework their hottest 5 Series, with a revised grille that echoes the M6 along with modestly resculpted headlamps. The rear end appears wholly unaltered. Interior changes gleaned from a look at the cabin photos include an updated touchpad-equipped iDrive controller and a new steering wheel cribbed from the M6.
No new word on changes to the 4.4-liter, twin-turbo V8 powertrain, but in late April, we heard that BMW was readying new competition packages for the M5 and M6. The packages are said to include 15 more horsepower, revised suspension and steering, along with new wheels and blackened exhaust tips. Given that BMW is known for habitually underrating its cars' horsepower outputs (particularly its M models) we can't help but wonder if its engineers will need to do anything other than wave a magic wand to corral those extra ponies underhood...
