Jay Leno puts focus on some retro-inspired BMW bikes

Jay Leno puts eight wheels on display this week for Jay Leno's Garage from a quartet of retro-inspired BMW motorcycles. They are the creations of husband and wife team Larry and Carol Romestant, who build each one in their home garage.
Larry is a former aerospace engineer who loves BMW bikes, especially the K models. Now, he's combining his passion with a real talent for fabrication to build his own cycles with his wife. With Larry and Carol the only ones working on these projects, it takes them six to nine months to build each one. In addition to the old-school looks, the motorcycles are supposed to be a bit more user friendly than stock. For example, one of them ditches the standard five-speed gearbox in favor of a six-speed unit to be a little more comfy when cruising at high speeds.
Since there isn't enough time to take all four of them for a ride, Jay picks his favorite to test out on the open road. Scroll down to see which one he chooses.

2015 BMW X3 arrives with tweaked styling, diesel option

The luxury crossover market has been a huge success for BMW, having sold over a million X3 models worldwide since the CUV first went on sale in 2003, not to mention all of the momentum its had with the larger X5. At the Chicago Auto Show, BMW is unveiling the refreshed 2015 X3, featuring an improved design, a new diesel engine option, and a rear-wheel drive variant.
The X3 is getting some handsome upgrades to the exterior. The twin, circular headlights now extend to touch the slightly widened, chrome kidney grille, to bring the styling in line with the 3 Series and 4 Series. (LED headlights are now optional, as well.) The front bumper gets reshaped brake cooling ducts, and the rear bumper gets a touch of additional metal trim at the bottom. BMW has also added standard LED turn signals in the side mirrors.
BMW has enhanced the interior with added chrome trim, high-gloss black trim around the center console, sliding covers for the cup holders and new interior upholstery designs. The X3 is also getting a major boost in optional technology - there's a new Parking Assistant, as well as an Active Driving Assistant with adaptive cruise control, Lane Departure Warning, Frontal Collision Warning, Pedestrian Warning, and City Collision Mitigation.

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.
