This BMW i8 gains Alpina V8 power thanks to tuner

German engineering firm Gabura Racing Technologies will strip out everything that makes a BMW i8 green in an effort to create a much wilder machine. Rather than a plug-in hybrid with a turbocharged three-cylinder, the company will cram in a twin-turbo V8. The firm even intends to produce a limited run of these insane conversions for customers. Gabura hasn't actually built one of these beasts yet, but it provided several glimpses of how it would work at the 2015 Professional MotorSport World Expo in Cologne, Germany. The company stuffs the engine under the front end in what looks like a quite snug fit. In several of the photos, the top of the valve covers even appears to be above the base of the windshield. According to BBC Autos, this mill is the S63 4.4-liter turbocharged V8 from the M5 and M6. Additional tuning with some help from Alpina allegedly pushes output to around 760 horsepower – more than double the i8's stock figure. One of Gabura's own six-speed sequential gearboxes reportedly transfers the power to the wheels. Gabura recently posted on Facebook that the engineers are now ready for the first conversion. They promised to "completely rebuild it inside-out, fueled with racing technology." We're very curious to see how an i8 looks and sounds after such a significant transformation.

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.

Feds greenlight BMW X5 diesel sales for 2016 [UPDATE]

Update: The EPA also confirmed that the 2016 X5 diesel passed the tests in a statement: "EPA and the California Air Resources Board certified BMW's 2016 diesel X5. EPA is performing additional screening when it conducts confirmatory emissions tests before issuing a certificate. Our screening tests found no evidence of a defeat device in the 2016 BMW X5, concluding our certification review." The 2016 BMW X5 xDrive35d is the latest diesel model to pass rigorous emissions tests by the Environmental Protection Agency and prove that it doesn't circumvent regulations with a defeat device. The luxury SUV can now go on sale to customers, and BMW spokesman Hector Arellano-Belloc confirms to Autoblog the first of them should arrive at dealers around late January. The automaker previously delayed production of the new model at the Spartanburg plant until the EPA completed certification. Following Volkswagen's emissions cheating, the EPA, California Air Resources Board, and Environment Canada began stricter testing for diesel vehicles to ensure that they met regulations. The first models to get the additional scrutiny were the 2016 Chevrolet Colorado and GMC Canyon with the Duramax engine, and they passed with no problems. According to Reuters, the X5 diesel was the only other non-VW from the 2016 model year that the agencies needed to certify with this more rigorous evaluation. The 2016 X5 xDrive 35d starts at $58,695 after the $995 destination charge. A 3.0-liter six-cylinder engine sends 255 horsepower and 413 pound-feet of torque through an eight-speed automatic to the all-wheel drive system. BMW claims that the vehicle can reach 60 miles per hour in 6.5 seconds, and the 2015 model carries an EPA fuel economy rating of 24 miles per gallon city, 31 mpg highway, and 27 mpg combined.
