BMW X4 M40i spotted testing in Germany

The stream of segment-busting BMW variants is showing no signs of letting up, and with the latest addition now upon us, questions have been circulating as to whether the Bavarian automaker would do an M version of the new X4 crossover. The jury may still be out on that proposition, but the latest intel suggests that, while a full-on X4 M may not be in the cards, a next-best-thing X4 M40i is in the works. And that appears to be what we're looking at in this fresh batch of spy shots.
Spotted for the first time undergoing testing in Germany, this X4 is tipped to be the next addition to the M Performance line that's already given us near-boiling models like the M135i and M235i on the one hand and the diesel-powered M550d, X5 M50d and X6 M50d on the other. Power in this case is tipped to come from the same 3.0-liter turbo six as the upcoming M2, producing between 360 and 380 horsepower.
Unlike the current top-of-that-specific-line X4 35i, which has two tailpipes on one side, this partially-camouflaged prototype has one pipe protruding from each corner of the rear bumper, but looks like it could easily accommodate twin pipes on both sides. Expect commensurate suspension, brake, rolling stock, aero and trim upgrades to come as part of the package, though they likely won't be quite as substantial as those applied to the X5 M and X6 M.

2014 BMW 328i xDrive Gran Turismo

"The Ultimate Driving Machine" has been BMW's tagline for nearly 40 years. Launched in the 1970s, the marketing campaign was a stroke of genius by ad firm Ammirati & Puris, as the phrase helped differentiate the imported Bavarian cars from their fellow European rivals by subtly pointing out that Mercedes-Benz and Audi were offering luxury models, while BMW was selling sporty and youthful driving dynamics. The campaign worked - some would argue that stands among the most effective ad campaigns ever - and countless Baby Boomers embraced the brand's fun-to-drive image by taking delivery of the company's new models.
BMW still boasts that its vehicles are "The Ultimate Driving Machine" four decades later, but the brand is very different today. It offered just a few model lines in the mid-1970s, and only a handful of vehicles within. In 2014, the automaker offers an exhaustive range comprised of nearly a dozen lines with almost 50 different models. To survive and thrive, BMW has decided it must massively broaden its appeal.
One of the latest arrivals to BMW's ever-growing stable is the 2014 3 Series Gran Turismo. The five-door hatchback is best thought of as a smaller version of the company's 5 Series Gran Turismo built on stretched 3 Series platform that, in the case of this test car, shares the running gear of the 328i xDrive sedan. On paper, the five-passenger vehicle checks all the proper boxes with regards to performance, utility and economy. But does this family-focused 3 Series still deliver driving dynamics that qualify it for the title of Ultimate Driving Machine?

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.
