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 i8 offers you a fast ride to the future for $135,700* [w/video]

BMW's long-form teasing and rollout of its incredibly cool i8 has put us in a unique position to report from its world debut here in Frankfurt. Typically, an auto show debut marks just the start of the information dump about a new vehicle. The i8, however, is a car that we've already driven and reviewed, so perhaps the biggest news from the show floor is the official price of the thing, as well as getting to see it live and in person, of course.
Arriving in US showrooms in the spring of 2014, the i8 performance plug-in hybrid will carry a price tag of $135,700 (*not including $925 for destination and handling charges). That kind of cash puts the i8 near the very top of the BMW range (slotting just under the top-trim 7-Series models), and will buy a massive amount of new technology.
The four-seat i8 has the look of a true supercar, and its new-tech drivetrain will offer up the performance of a stirring sports car, at least. A TwinPower Turbo, three-cylinder, 1.5-liter engine will make 231 horsepower and 236 pound-feet of torque that's gets sent to the rear wheels, while a 96-kilowatt electric motor doles out 131 hp and 184 lb-ft of maximum torque to the fronts. Total system output of 362 hp and 420 lb-ft allows the i8 to sprint to 62 miles per hour in 4.4 seconds with all-wheels-driven handling, and it still returns an astonishing 94 miles per gallon US.

BMW M4 to debut in Detroit, lose manual transmission

BMW took the wraps off its M4 Concept at Pebble Beach last weekend, and many speculated that the highly anticipated production version of the sleek new two-door sports coupe would debut at the Los Angeles Auto Show later this year. But a well-placed source tell Autoblog that the E92 M3's successor won't arrive in Southern California this November. Instead, the German automaker will wait until the Detroit Auto Show in January for its first official reveal.
An all-new 3.0-liter inline-six with twin turbochargers is expected under the hood, and it should provide about the same horsepower as the current 4.0-liter V8 (rated at 414 horsepower), but with much more torque that arrives lower on the tachometer. The lightweight engine is said to have an impressively high redline, which is unusual for a turbocharged engine.
Unfortunately, Save the Manuals members aren't going to like this next bit of news. After four generations of three-pedal M3 models, our source says the upcoming F82 M4 will arrive with a dual-clutch transmission (DCT) as standard equipment - with no manual option - just like the latest iteration of the track-ready Porsche GT3 (few have complained about the automaker's PDK after driving the latest sports car from Stuttgart). In exchange for some moans, groans and gripes from enthusiasts, BMW's DCT mounted aft of the M4's inline-six will provide quicker acceleration and improved fuel economy.
