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.

Reveal of next-gen BMW 7 Series set for June 10

Executive vice presidents of the world, your next sedan is debuting in just a few days. BMW is finally taking the wraps off the next-gen 7 Series on June 10, and the Bavarian brand's teaser video provides a few early hints about the high-class model. Highlighting a 750Li, the camera in the teaser swoops around the sedan to show off its laser headlights. The badge for BMW's Carbon Core also gets some of the limelight here to proclaim the extensive use of carbon-fiber-reinforced plastic. This clip doesn't give much more away, though. However, BMW has already spilled the beans about some of the other futuristic features for the new 7 Series in an earlier tease. The sedan is essentially a rolling technological showcase and offers functions like remote-controlled parking that's run from the key fob. Inside, using the infotainment system is possible with three-dimensional gesture control by waving your hand in the air in the right area. The extensive amount of CFRP in the passenger cell also helps save 287 pounds over the previous generation. If buyers are really looking for opulence, they can also reportedly order a massive, panoramic glass roof and a leather-covered engine cover. Expect a full rundown of all of the 7 Series' lavish features when the sedan debuts.

Dinan S3-R BMW 1M Coupe

I nearly shed tears a few years ago upon learning that BMW was only planning to produce a very limited quantity of its then-new 2011 1 Series M Coupe. In simplest terms, the two-door was a 1 Series fitted with a modified version of the automaker's twin-turbocharged 3.0-liter inline-six, and the running gear (gearbox, driveshaft, axles) from contemporary M3 models. It was also a return to form for the brand. Aggressively short and stubby in stature but packing telltale flared wheel arches that hinted at its potential, the four-seater was a spiritual successor to the original (and much loved) E30 M3 from decades earlier.
After spending a day with the original high-performance 1 at New York's Monticello Motor Club, I declared, "The little coupe with the big flares is old-school retro cool and deliciously fun to drive ... the new BMW 1 Series M Coupe doesn't target boy-racers, it targets enthusiasts." Yet sadly - and despite strong demand - BMW limited the model's production to just one year. All told, only 740 units made it to the States, and each was gobbled up at a starting price of $46,135, a price tag history will show to be a bargain.
Since I had little hope of even driving one again, I deliberately pushed all memories of BMW's 1 Series M Coupe from my mind - until my phone rang recently. On the other end was a representative from Dinan Engineering who wanted to know if I would be interested in driving the company's new S3-R BMW 1M. A quick Google search revealed it to be a heavily modified version of the discontinued 1 Series M Coupe. As if they needed an answer...
