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.

Elvis Presley's BMW 507 has never looked better

After two grueling years of work, BMW Classic is finally finished restoring the 507 roadster that once belonged to Elvis Presley. Now that it is restored to original condition, the vehicle will be on display at this year's Concours d'Elegance in Pebble Beach, CA, on August 18. The 507 will be in the exact same shape as when the King of Rock 'n' Roll took delivery of it on December 20, 1958. Not only did BMW Group Classic bring the 507 back from the scrapyard, it also went to great measures to ensure that the classic was restored in an authentic manner. The vehicle was painted once again in Feather White. But the primer coat, filler, and top coat were applied using methods that were used roughly 60 years ago, giving the 507 a truly original shine. The 150-horsepower 3.2-liter V8 was restored to its original spec, but utilizes a variety of old and new components. Other notable features include a black-and-white interior, center-lock rims, and a Becker Mexico radio. The 507 will be on display alongside numerous vintage BMWs as the company celebrates its centennial.

2014 BMW M6 Gran Coupe is ready for your favorite roads

We've known about the ins and outs of the lovely BMW M6 Gran Coupe for a while now, but that doesn't mean we weren't happy to see the thing in the metal for the first time, here in Detroit.
The M-tuned Gran Coupe utilizes the same 4.4-liter forced-induction V8 that powers both the BMW M6 and the M5, with an output of 560 horsepower and 500 pound-feet of torque. The fast four-door brings up 60 miles per hour in just 4.1-seconds - the same sprint time as the M6 coupe and a few tenths quicker than the M5 - and up to a limited top speed of 155 mph.
We love those performance figures - this is one new Bimmer that we're amped to get some seat time in - though we're not super crazy about the selection of chrome wheels on this particular show car. Tells us what you think about the hotted up Gran Coupe in comments, below.
