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 i8 recalled over possible fuel leak

Some 223 examples of the 2014 BMW i8, built between May 16, 2014 and September 16, 2014, are being recalled over a potential fuel leak. A bolt used to secure a ground cable from the chassis structure to the fuel tank could have been welded improperly; if so, gas might leak from the tank. The recall began in November, so if any of you owner types aren't aware by now, you can take your i8 to the dealer for replacement of the fuel tank if necessary. A bulletin from the National Highway Transportation Administration below has more details. Related Video: Report Receipt Date: OCT 27, 2014 NHTSA Campaign Number: 14V674000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 223 Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America, LLC (BMW) is recalling certain model year 2014 i8 vehicles manufactured from May 16, 2014, to September 16, 2014. A bolt used to attach a ground cable between the tank and the vehicle chassis may not have been properly welded during manufacturing. CONSEQUENCE: An inadequate weld of the bolt to the fuel tank could cause a fuel leak. In the presence of an ignition source, a fuel leak could lead to a fire. REMEDY: BMW will notify owners, and dealers will inspect and replace the fuel tank if necessary, free of charge. The recall began in November 2014. Owners may contact BMW customer service at 1-800-525-7417 or CustomerRelations@bmwusa.com.

2016 Pebble Beach Concours d'Elegance: It's all in the details

It's no secret that Pebble Beach is an ode to gorgeous, and mostly, classic cars. The car show may be a place for automakers to showcase extremely expensive cars to wealthy buyers, but it's also one of the go-to places for enthusiasts that love automobiles and culture. While it's easy to be overwhelmed by the overall beauty of a car, the real magic often needs closer inspection to be realized. Every car at Pebble Beach is a work of art, but the true beauty of the vehicles lies in the details. And Autoblog's photographer, Drew Phillips, managed to capture the details on some gorgeous cars. From the Lamborghini Miura's exquisite steering wheel to Rolls-Royce's Spirit of Ecstasy, it's all at Pebble Beach. We think the details on some of the cars are prettier than the cars themselves, but don't take our word for it. Check out the beautiful gallery above and enjoy the tiny bits and pieces behind some of the prettiest cars in the world.
