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 1 Series GT morphs into production-spec 225i Active Tourer

Based on the effort - and money - BMW is spending to break off the coupes and convertibles in its lineup as even-numbered models (like the new 2 Series and 4 Series), we figured the production version of the 2012 Concept Active Tourer was a lock to wear the 1 Series GT name. These spy shots paint a different picture, however, as they show the car seemingly in full showroom-ready trim during a photo shoot, wearing the 225i name indicating that it will be in the 2 Series family.
While it's still very possible that this badging is the final bit of trickery for disguising the front-wheel-drive 1 Series GT, the hatchback itself appears to be the real deal. Aside from new fascias, a smaller grille and slightly different lights, the styling of this "225i" stayed pretty true to the Concept Active Tourer. Thanks to our long-lensed photographer, we also get a brief glimpse inside the hatchback, which reveals a two-tiered instrument panel layout including the free-standing navigation display that is similar to the concept car.
Regardless of what name this new model will wear, expect it to be unveiled at next year's Geneva Motor Show in March before arriving in the US sometime in 2015.

BMW M235i Racing restores our faith in 'M'

Based on the upcoming BMW 2 Series and aimed at amateur and semi-professional racers, the 2014 BMW M235i Racing is a stripped-down, race-spec coupe ready to take on the Nürburgring in the VLN Endurance Championship race series against cars from Audi, Porsche and Toyota.
Obvious in the image above (click to enlarge), BMW has given the M235i Racing the wide-body treatment with a track that has been stretched by 3.5 inches. Under the hood, the 3.0-liter turbocharged inline six-cylinder receives a power boost from a stock 322 horsepower up slightly to 333 hp, while other modifications include a full FIA roll cage, a racing fuel tank and a limited slip rear differential.
The M235i Racing replaces the M3 GT4 as BMW's factory racer, and it will be priced at 59,500 euros (close to $80,000), which is about as affordable as a factory-prepped racecar can get. The full press release is posted below, but we can't wait to see this car in action next year.
