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.

The importance of Angel Eyes, Ventiports and four round taillights

Just the other day, we told you about how Lincoln isn't really a luxury brand, according to Ford's head design man, J Mays. His argument was that Lincoln lacked the unique DNA to differentiate it from the rest of the market, although the arrival of the MKZ is beginning to change that. Now, we have this video from Autoline Detroit, where Jim Hall, an analyst for 2953 Analytics who was quoted in yesterday's Lincoln story, explains the influence of certain styling cues and how they impact the brands.
Using BMW (Angel Eyes) and Buick (Ventiports) as examples for small, simple touches that serve to distinguish the brand's vehicles on the road, Hall then points out how changing trademark styling features, as Chevrolet has done on the new Corvette Stingray, can hurt the vehicle's public perception. Take a look at the full video below for an interesting dive into what these styling features mean to their individual brands.

2015 BMW i8 Prototype

M Meets Edison
The real telling moment for the new BMW i division will be seeing how the recently tested 2014 i3 sells in its various markets, since that is the car that changes how we perceive our expectations of the brand. But this 2015 BMW i8 green supercar has all the earmarks of a slam-dunk project, we just needed to drive it and make sure for ourselves.
BMW has a spectacular test facility in southern France, called Miramas, and that's where we just had our first brief go behind the wheel of the i8. There were three cars for us there and they were dressed up in exactly the same paisley camo that we've all seen in the spy photos published everywhere for the past year. The interiors, though swathed in masking to hide all the details, varied in their color.
