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 looking to save billions with cost cuts

BMW is planning a fairly extensive overhaul in a bid to recoup some its annual costs, with CEO Norbert Reithofer (pictured above) aiming to save three to four billion euro ($4 to $5.4 billion) per year to help keep the company's profit margins between eight and 10 percent, while also maintaining investments in production expansion and new tech. BMW's profit margins sat at 9.4 percent in 2013.
According to Automotive News Europe, Reithofer is none too pleased about costs at Mini and on the 1 Series, although neither AN nor its source story, from Germany's Manager Magazin, elaborate on what steps could be taken to improve losses on either project. That makes it hard to figure out just where the fat will be trimmed from.
What may happen, though, is that BMW attempts to trim 100 million euros ($135 million) from its German labor costs each year; a solution hinted at a few weeks ago by Germany newspaper Muenchner Merkur. While a dramatic cost reduction, 100 million euros still doesn't begin to even approach the savings envisioned by Reithofer.

Motor Trend first to compare Jaguar XE and BMW 3 Series

How many automakers have loaded up how much ammo and taken how many shots at the BMW 3 Series? Yet here we are, decades on and at least a decade away from the 3 Series' halcyon days, waiting for someone to give the sport sedan something beyond a flesh wound. In this most recent episode of Head 2 Head, Johnny Lieberman goes to Spain to figure out if the Jaguar XE is the sedan to do it. Here the champion wears the guise of the 335i M Sport, powered by a 3.0-liter, turbocharged, inline-six with a square 300 horsepower and 300 pound-feet of torque run through a ZF eight-speed transmission. After a short time behind the wheel Lieberman quotes from a familiar hagiography, saying it's evident "just how great this car is and why it defines the segment." The all-aluminum challenger from Jaguar comes in XES trim, meaning a 3.0-liter, supercharged V6 with 340 hp and 332 lb-ft. It uses the same eight-speed transmission as the BMW, but with different programming. According to the specs in the video, some of which are manufacturer estimates, the Jaguar is heavier, more expensive, and much thirstier at the pump. Away from the spreadsheet, Lieberman holds that the XE looks better and feels more special inside. In case you're wondering, the comparo was done before MT could get its mitts on the 320-hp BMW 340i. Lieberman says the English company spent its money on the XE suspension and it shows, but there have been other efforts from other automakers with excellent dynamic chops that weren't enough to threaten the BMW. His final assessment is that one of the two cars is awesome, and one is quite a bit better. Watch the video to find out which is which.
