Popular Mechanics Breakthrough Awards honors GM Super Cruise, BMW i3

Our friends at Popular Mechanics have announced the winners of their 2013 Breakthrough Awards, which honor innovations and new technologies in a variety of fields, ranging from medicine to electronics to space travel. Among the winners were a pair of automakers.
The BMW i3 was named one of PM's product breakthroughs, and while the diminutive city car has a range comparable to other electrics, Popular Mechanics was impressed the i3's use of carbon-fiber-reinforced plastic, which allows the i3 to tip the scales at just 2,800 pounds. But the i3's space-age materials wouldn't have been such a smash if it were priced beyond what the general public could afford. BMW's ability to offer a vehicle with such an advanced construction for around $42,000 (nearly half the price of the Cadillac ELR and only about $7,000 more than a Chevrolet Volt or Ford Focus Electric) is wildly impressive and speaks volumes about the future of ultra-light composites in the auto industry.
The other big winner comes from General Motors, which was named an Innovator this year for its semi-autonomous Super Cruise technology that's currently being tested on a Cadillac SRX. The technology, which we've reported on before, combines adaptive cruise control and lane centering into a super system that will allow hands-free driving under certain conditions.

Next-gen BMW 5 Series sedan spotted with production body, possible PHEV

The current BMW 5 Series is just a few years old since its 2009 debut, but the Bavarians are already preparing to put the model out to pasture. Here's our first glimpse at the production bodywork for the next-gen sedan after spotting the wagon version during testing – twice. While the cladding and swirling camouflage make specific details difficult to discern, it doesn't look like we should expect any massive changes in design language from the new model. The nose appears to dip a bit more at the tip of the front end, but otherwise there's no way to mistake this as anything other than a 5 Series. Squint hard enough at the front left fender and you can notice what seems to be a small door. Our spies think that this might be hiding the charging port for a plug-in hybrid version. While the styling doesn't appear to be changing much, the next 5er reportedly has a new platform underneath the skin that supposedly will help it shed around 220 pounds. The debut for this lighter but likely similar looking BMW is expected sometime in 2016.

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.
