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 and Roland Sands show off Concept 101 custom bagger

Though BMW may not be the first motorcycle manufacturer that comes to mind when you think of cruisers, that's precisely what the German marque has unveiled – in concept form at least – at the Concorso d'Eleganza Villa d'Este this year. Appearing alongside the 3.0 CSL Hommage concept, the BMW Concept 101 is a custom "bagger" created in California through a collaboration between BMW Motorrad, BMW Designworks, and legendary bike builder Roland Sands. Better suited towards cruising down the highway than carving up a racetrack or a dirt trail, the Concept 101 strikes a rather stunning (if uncharacteristic) form. The elongated shape is rendered in materials like brushed aluminum, carbon fiber, and wood trim, tapering towards the rear that encompasses two hard saddle bags characteristic of this style of cruiser. The top half of the bike is done up in lighter shades than the dark bottom, capped by a saddle crafted in fine-grain black leather, perforated black leather and a strip of brown leather. Power comes commandingly from an inline-six displacing 1.6 liters – or about 101 cubic inches, which along with Highway 101, gives the concept bike its name. The engine breaths out through a pair of tailpipes, each with three outlets to emphasize the six-cylinder and envision what it would look like if Munich opted to take on the Honda Gold Wing F6C Valkyrie. Of course this isn't the first time BMW has done a bike with Roland Sands, nor the first time it's displaying a bike concept at Villa d'Este. Last year the German marque displayed the Concept Roadster at the same show, and did the Concept Ninety with the same custom shop at the previous year's concours. BMW Motorrad "Concept 101" - The Spirit of the Open Road. Munich/Cernobbio. Every year, the most impressive representatives of the mobile past and future on both two and four wheels assemble at the Concorso d'Eleganza Villa d'Este for a very special get-together on the shores of Lake Como. Amid this extraordinary blend of the traditional and the contemporary, BMW Motorrad once again presents a breathtaking concept study: the BMW Motorrad "Concept 101". "The Concept 101 opens up a new chapter in the history of our concept bikes. It is the BMW Motorrad interpretation of endless highways and the dream of freedom and independence - the perfect embodiment of "American touring". Designing this big touring bike study was amazingly exciting for us because we haven't been involved with a motorcycle concept like this before.

Ward's announces 10 Best Engines 2015

Ward's Auto has named its 10 Best Engines for 2015, covering a range of powerplants from fuel-sippers to fire-breathers. As with past years, forced-induction reigns supreme, with seven of the ten engines featuring a turbo or supercharger. This year is slightly different, though, as two of the seven blown engines are turbocharged three-cylinder mills, from the Ford Fiesta and Mini Cooper. They're joined by the 2.0-liter turbo four from the Volvo S60, the 1.8-liter turbo four from the Volkswagen Jetta and the 2.0-liter boxer from the Subaru WRX. BMW and Chrysler were the only marques to be named to this year's list twice, with the electric motor from the i3 joining the Mini's three-pot, and the 3.0-liter turbodiesel V6 in the Ram 1500 and Jeep Grand Cherokee repping the diesel crowd, alongside a certain supercharged monster. Hyundai also took a prize with a zero-emissions powertrain, with the Tucson FCV's 100-kilowatt fuel cell making the list (apparently Ward's is quite generous with what it deems an "engine"). Rounding out the list are two Autoblog favorites, each displacing 6.2 liters, but producing their power very differently. On the one hand, Chevrolet's overhead-valve, 455-horsepower V8, found in the Corvette, makes its power the old fashioned way. And in the other corner, we have one of the most exciting engines of the year – the 707-hp, 6.2-liter, supercharged Hellcat V8, featured so prominently in the Dodge Challenger and Charger SRT Hellcat. "We spend a lot of time reading the powertrain tea leaves throughout the auto industry, and we're proud that this year's list is a microcosm of all the latest innovation coming from automakers," said Ward's Editor-in-Chief Drew Winter in a statement. "It's not just a list for enthusiasts or for environmentalists," he says. "There's something for every vehicle shopper and every budget. All the powertrains on this list deliver a first-rate driving experience," Winter added. Scroll down for the full list from Ward's, and let us know which engines you think belong and which should have been included in this year's rankings.
