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.

Is the BMW i8 actually already sold out?

The other day we brought you a report from Reuters, which quoted BMW's global sales chief Ian Robertson as saying that the Bavarian automaker had already sold out the entire year's production run of its new i8. Impressive, sure, but perhaps not all that unusual for a groundbreaking new sportscar from a major automaker, of which only limited quantities are typically built. But is the i8 really sold out?
Our compatriots at Car and Driver chased down the story and report that Robertson's claims aren't exactly accurate. According to C/D, the numbers are based on sales projections, not actual orders taken. So while BMW may build upwards of 1,900 i8 coupes next year and over 5,000 in 2015, and while they're all expected to sell, that doesn't mean that it's too late to get your order in. That is, assuming you have the $135k on hand and don't mind getting just three cylinders back in return.

BMW makes the M4 extra special with a huge wing

BMW has all of the bases covered in its lineup, especially when it comes to its 4 Series models. Don't like going to the track? There's the BMW 430i and 440i, which are available as a coupe and gran coupe. Drivers looking for a track-friendly car that can also be used on the road will be steered toward the M4. BMW even built the hardcore M4 GTS for drivers that spend all of their time on a track. Now, it looks like BMW is trying to bridge the gap between the M4 and the M4 GTS with a special-edition model. Our photographers caught BMW testing an M4 with some extreme aerodynamic components around the Nurburgring. With its aggressive front end, massive wing, and sporty rear diffuser, the prototype M4 appears to be similar to the special-edition M4 Competition Sport that BMW released in Spain. The Spain-only special edition was marketed as a softer version of the M4 GTS with less power and usable rear seats. With a similar look and visible rear seats, this prototype indicates a similar track-focused special edition model. Since the M4 is only a few years old, it's unlikely that BMW is testing a new model, but the automaker could be testing aerodynamic components for a refreshed model down the road. A cheaper, more usable M4 GTS, though, would be the perfect car to round out BMW's current lineup. Related Video:
