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.

2015 BMW 228i xDrive

Has BMW lost its edge? The answer to that depends on what vehicle you're discussing. The company's products, while still quick and agile, are softer and more forgiving than they've ever been. And while this change may be worrying if we're talking about an M3 or an M5, is it necessarily a bad thing for more mainstream models? That's our question after a week behind the wheel of the BMW 228i xDrive, a vehicle that succeeds the beloved, driver-focused BMW 1 Series. In some ways this new car is a let-down, but in many other areas the new 2 Series is just plain better. The latter is particularly true if we're talking about the new sheet metal. While the 1 Series was a great source of compact, rear-drive entertainment, it wasn't a pretty car. The new 2 still isn't a stunner, but it benefits from BMW's latest design language. It looks wider and more muscular than the squat 1 Series, although certain elements, like the daylight opening and rear taillights, look like they were plucked right from the old car. Overall, BMW has crafted a more premium aesthetic for the exterior of its entry-level coupe. A weak spot for the 1er, the 2 Series cabin sports a similarly upscale redo. Like the last-gen car, the top of the dash is home to a master display for the iDrive system (a neutered, non-navigation version on our test car), while the lower half of the center stack is dedicated to analog controls for the HVAC and audio. The dash layout is similar to the 1 Series, but the execution feels more upscale. The trim around the radio and climate controls includes aluminum and gloss accents. The passenger side dash and center console ditch soft-touch plastic for authentic materials – our car uses real brushed aluminum, although piano black and wood are also available. As with all recent BMWs, the combination of the automatic gear lever, the knob and buttons of the iDrive system, and the toggle switch for the Driving Dynamics Control system mean there's a lot of clutter where the driver's right hand falls. What hasn't changed with the 2 Series is the excellent relationship between the driver and the primary controls. Our test car wears the Sport Line package, which does without BMW's obnoxious, too-large-diameter M Sport steering wheel. Instead, there's a thick-rimmed wheel with textured leather and red contrast stitching. It feels more natural than the oversized M wheel, while this car's large paddle shifters have a solid, well-damped action.

2013 BMW M3 Coupe Lime Rock Park Edition

Sic Transit Gloria
I like difficult cars. I like turbo "moments," dramatic weight distribution, low-grip, peaky power delivery, and overly quick steering, along with ultra-short wheelbases and any number of other non-racecar-perfect dynamic foibles. I love the newest generation of BMW cars and engines - all turbo'd up with tons of torque and power everywhere in the rev range, too. But what I think the enthusiast community will miss when this 2013 M3 Coupe becomes the 2014 M4 Coupe - replacing its idiosyncratic, small-displacement, revvy V8 for something like a triple-turbo, directly injected, inline six-cylinder powerhouse in the process - is the work it takes to drive the car fast and perfectly. Sometimes small flaws just make things better; my mistress' eyes are nothing like the sun, and all that.
The idea of this E92 M3 going away then, magnified by the loss of the M3 badge for the coupe, is at best bittersweet for me. This generation of M car is already surpassed in terms of raw thrills by the better-than-ever Mercedes-Benz C63, a car that doesn't ask its driver to sacrifice low-end grunt or the very latest in amenities in return for stellar backroad performance. Yet any time I've been lucky enough to lap a track in the M3, it has quickly become clear that the Bimmer is the better on-edge tool. With the freedom to wring the neck of the 4.0-liter V8 and room to exercise the lovely balance of the car, the E92 is hard to match (even six years after its debut).
