BMW could expand 'i' lineup

Well, this isn't exactly a surprise. BMW CEO Harald Krueger (shown above) has hinted that the i3 electric car and the i8 plug-in supercar could soon be blessed with a bouncing brother, perhaps in the form of the oft-rumored i5. Specifically, Krueger told Frankfurter Allgemeine Sonntagszeitung (as reported by Automotive News) that there was certainly room in the middle of the i sub-brand's current two-model lineup "from the number point of view." The exec declined to offer any additional information. Unlike the i3 and i8, which are their own unique products independent of the rest of the BMW range, the i5 will allegedly be based on 5 Series sedan. It would also eschew the all-electric approach of the i3 in favor of a new and different version of the plug-in hybrid powertrain used in the i8. Rather than that car's turbocharged, three-cylinder gas engine, 129-horsepower electric motor, and 357 total system hp, the rumored i5 – according to our most recent report – would be significantly more powerful. There are rumblings that the new model would have anywhere from 544 hp to 640 hp, with at least two electric motors (one on each axle, making it effectively all-wheel drive). On top of the high performance, the i5 will have no issue running on EV power. According to one report, there'd be up to 78 miles of electric range, and would run purely on electricity up to 36 miles per hour. Even then, the gas engine would only join the party when under hard throttle. What do you think? Will BMW come out with a four-door PHV that could potentially outrun the current M5?

Behind the Scenes of BMW's 'Drift Mob,' Part 2 [w/video]

After spending four days practicing about a dozen drift stunt moves in a parking lot for an upcoming BMW "Drift Mob" internet mini-film, Rhys Millen, Sam Hübinette, Dai Yoshihara, Rich Rutherford, and Conrad Grunewald are finally ready for show time. We are brought to the huge urban traffic circle to see the stunts performed midway through the day to observe for a couple of hours.
The undertaking is massive, with multiple cameras set up, scores of crew members, a helicopter filming from above, a rigged pickup for car-to-car shots, sidewalks lined with security and plenty of curious onlookers, and oh, yeah, a major intersection of a top world city shut down for an entire weekend.
The five drifting legends are nestled in their identical red BMW M235i coupes, which have been modified with special handbrakes but essentially nothing else you can't get on a stock version, and are listening to direction from director Mic Rodgers and stunt coordinator Riley Harper. We're basically given free rein of the set, to shoot the cars, the drivers, and at one point, even hopping in with Yoshihara for one of the admittedly more tame stunts. Even then, the g-forces are so severe that they flip our cameraphone's video recording from landscape mode to portrait. Yes, this is a pretty cool day to be reporting on cars, and as we said during our first installment of our behind the scenes coverage of Drift Mob, we're honored to be the only US media outlet here to tell the tale.

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.
