BMW showcases M2, M4 with M Performance Parts at SEMA

The halls of the Las Vegas Convention Center may be filled this week primarily with customized automobiles from one side of the Pacific or another. But that's not to say that European automakers can't come out to play too. Take these two custom rides from BMW, for example. They're each based on Munich's latest performance coupes, but taken further with the addition of extra M Performance parts. The larger, more potent, and more thoroughly revised of the two is based on the M4. For the SEMA show, the Bavarian automaker has fitted it with a carbon aero kit including new front elements, diffuser, and spoiler, as well as wing mirror caps. The side sills are done in plastic, and the grilles have been blacked out. The whole thing rides on a lowered coilover suspension, and features a new two-mode stainless-steel exhaust system with titanium silencer and carbon tips. Meanwhile, the interior is trimmed out in carbon fiber and Alcantara with new a steering wheel, shifter, pedals, and LED door projectors. The SEMA show also presents BMW with the opportunity to present its first M Performance parts for the new M2 coupe. The smaller model has been decked out with new grilles, carbon rear spoiler and mirror caps, as well as new suspension components and exhaust. The interior has similarly been done up with new control surfaces, carbon accents and Alcantara trim.

The new products presented at SEMA to trade experts influence the entire scene and set trends. At this year's SEMA show from November 3rd to 6th 2015, BMW presents a selection of distinctively sports-oriented BMW M Performance Parts to the trade fair audience. Located on the lower level of South Hall (Stand 40247), trade fair visitors will see a BMW M Performance modified BMW M4 Coupe as well as the first BMW M Performance Parts for the new BMW M2 Coupe. What is more, the new "M Performance" inscription in dynamic technical design is to be seen on selected parts. The inscription reflects the increased dynamic flair of BMW M Performance as well as underscoring the essential functional orientation of all BMW M Performance Parts. Evidence of this is also to be seen in the new, extremely sporty parts and components with which BMW has fitted the demonstration vehicle.

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.
