BMW Motorad reveals Concept Stunt G 310 in Brazil

BMW has been on a bit of a concept motorcycle bent lately, and each has taken a decidedly different approach from one another. The Motorad division did the Path 22 scrambler concept in June, the Concept 101 custom bagger in May, the Concept Roadster last year, and the Concept 90 retro racer the year before. Now it's at it again with the Concept Stunt G 310. As you might have guessed, the G 310 is a stunt bike. Its compact form is built around a single-cylinder engine canted rearwards with a rotated cylinder head to help optimize the weight balance. The intake was moved forward and the exhaust towards the rear, mounted under the seat, to enable the rider's freedom of movement. It has long travel in the suspension, but still rides on a short wheelbase – perfect for impressing the crowds. To that end, it was designed with collaboration from four-time stunt riding champion Chris Pfeiffer. It's also got a lockable throttle so the rider can take his hands off the controls (not advisable for the rest of us). The beefed-up secondary rear brake can be actuated by a squeeze of the finger. Axle pegs allow for additional foot-placement options, red crash bars protect the mechanical elements, and a specially designed "stunt tail" is milled from solid aluminum and provides an additional foot-hold. The shape is adorned with an eye-catching neon livery designed to give the impression of movement, even when it's sitting still. The bike will be unveiled in Sao Paulo, Brazil, at South America's preeminent motorcycle show. BMW Concept Stunt G 310 – Street. Style. Stunt. 06.10.2015 Munich/Sao Paulo. With the world premiere of the BMW Concept Stunt G 310 at South America's largest motorcycle show, BMW Motorrad is presenting a completely new side: the uncompromising interpretation of an aggressive and agile stunt bike based on a single cylinder study. Thanks to his experience as a four-times World and European stunt riding champion, Chris Pfeiffer, contributed to the realisation of the BMW Concept Stunt 310. "Stunt riding is a demanding and multi-faceted sport. Ideally you need a compact, agile bike which is also stable and robust at the same time. You have to achieve the ideal balance between aggressiveness and control", explains Chris Pfeiffer. Compact proportions, highest-level agility.

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.

Mazda CX-5 named Japan's Car of The Year, Subaru BR-Z wins "Special Award"

The Mazda CX-5 stamped its Kodo design and SkyActiv technology authority all over the Japan Car of the Year awards, taking the top prize ahead of the Subaru BRZ/Toyota GT 86. It is Mazda's second victory in the last ten years, the 2005 MX-5 claiming the same trophy, and the fourth time the Hiroshima company has won.
The award is decided by 60 local "automotive experts and journalists," and open to any passenger car released in Japan from November 1, 2011 to October 31, 2012 that has sold more than 500 units. Each judge gets 25 votes, his or her top vote getting 10 points, the rest of the points being spread among the judge's choice for the next best four cars.
The second-place getters were the Toyobaru twins with 318 votes, the surprise being they didn't beat or get any closer to the crossover. The Subaru BRZ did claw some mojo back, earning the Special Award given to cars that have made "an exceptional impact." The BMW 3 Series was third overall and won the Import Car of the Year award with plenty of room between it and the second place Range Rover Evoque.
