BMW i3 takes to the track, circles it in a way you don't expect

So, who wants to see a BMW i3 race around a track. That's what we thought. It's not a long video, but it is entertaining, and the way the urban EV does a 'loop' at second 25 certainly caught out eye. The i3 is scheduled to go on sale in the US later this year and will start at $41,350. The diminutive electric vehicle has a top speed of 93 miles per hour and can hit 62 mph in 7.2 seconds. We found it a hoot to drive, but we're not sure if hardcore BMW performance fans will totally 'get' this car's performance. The i3 is great at what it does, but it wasn't born to hit the race track. After seeing this video, though, we want a crack at it, skinny wheels and all. You can get a behind-the-scenes glimpse here, where Chris Neff writes, "The i3 basically turns in on itself. This is one sharp turning radius, take a look at 24 seconds into the video. We were actually trying to get the i3 to do doughnuts, but the computer would not let the rear brake loose, still, you can see how it held and how sharp we were turning....about 27 times in a row." Watch all 49 seconds below. And wonder with us if whatever aerial device was used to get the shot that ends at four seconds in was destroyed just after the video cuts away.

2015 BMW S 1000 RR looks to retain sportbike supremacy

The BMW S 1000 RR is already a pretty potent member of the superbike ranks, but BMW is revealing a host of upgrades for this two-wheeled lightning bolt at the Intermot 2014 motorcycle show that should make it even faster.
The biggest additions to the latest 1000 RR are its new cylinder head, lighter valves and different intake cam to tweak even more power from the bike's 1.0-liter, four-cylinder engine, and BMW now rates it at a claimed 196 horsepower (or 199 horses if you go with the European measurement, converted from 146 kilowatts), a boost over the first-gen's 193 ponies, and 83 pound-feet of torque through a six-speed gearbox. Those adjustments would probably be enough to make the cycle a tick faster alone, but the Bavarian engineers also cut 8.82 pounds (4 kg) to bring the motorcycle's weight with a full tank of fuel to a feather-light 450 pounds. Much of that diet comes from the redesigned exhaust that cuts about 6.6 pounds off the scales.
Cradling that tweaked engine is a redesigned, lighter frame with fully adjustable springs. The bike also comes standard with Race ABS, stability control, seven-step variable traction control and three riding modes. In terms of styling, all of these changes are communicated through an updated fairing with repositioned, though still asymmetric, headlights.

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.
