BMW 4 Series Gran Coupe spotted wearing minimal camo, M Sport pack

The new BMW 4 Series is essentially the coupe version of the latest 3 Series. So it would stand to reason that the four-door version of the 4 Series, in turn, would be the 3 Series - right? Well, yes and no.
Just as BMW offers both a 5 Series sedan and a four-door version of the 6 Series called the Gran Coupe, so, too, will its 4-Series family expand. So following the release of the new 4 Series Convertible, here we have the latest batch of spy shots showing the upcoming 4 Series Gran Coupe - which in turn should not be confused with the hunchbacked 3 Series Gran Turismo, which is more of a sporty wagon than a four-door coupe.
The nearly ready test vehicle pictured here is wearing only minimal camouflage to hide some last few details, but also appears to be wearing the M Sport package that will bridge the gap (at least, visually speaking) between the base models and the M4 Gran Coupe that is all but certain to follow.

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 M4 Concept bows, takes handoff from M3 Coupe

Remember how, when the first BMW M4 Concept images leaked earlier today, we told you the official information would be coming later this evening? Well, scratch that. The whole kit and caboodle is now online, meaning all the official details are below, as well as a full gallery of high-res images above.
The replacement for the M3 Coupe, the Concept M4 Coupe shares a number of styling similarities with its dearly departed forbearer. To us, it's kind of like a mishmash of greatest hits from the new 4 Series and the old M3. The 4 Series headlights have grown on us, and the side grilles, which are part of BMW's Air Curtain and Air Breather system, are functional.
The power dome in the hood is smaller than on the M3, but is of a similar shape, while the rear diffuser and exhaust treatment look like they're lifted straight from the old car, aside from being finished in carbon fiber. Speaking of which, the carbon fiber roof sports a new touch, a cool BMW M tri-color that runs the length of the roof on the driver's side. The 20-inch M alloy wheels come in a twin five-spoke design, which has sort of become a calling card of BMW's M cars in recent years. Hiding behind those meaty wheels are M's carbon-ceramic brakes.
