There are many unusual things about the BMW i3 Concept electric minicar revealed last month, including its glass doors and roof, not to mention BMW's first production battery-electric powertrain. But the BMW i3 is also at the leading edge of another efficiency trend: tall, narrow tires that reduce the vehicle's wind resistance compared to the usual short, wide tires fitted to cars today. Fitting low-rolling-resistance tires to a line's most efficient models is now de rigeur. Over the years, these harder, lower-friction tires have gone through several generations, so that's today's versions...

Hyundai Developing 10-Speed Automatic For Future Luxury CarsEngines might be getting smaller in the pursuit of saving fuel but transmissions are going the opposite direction. Over the last few years different carmakers have rapidly increased the number of ratios available to drivers, with Mercedes-Benz giving us 7-speed autos, Lexus developing an 8-speed...

Solid State Electric Car Batteries Still 10 Years AwaySolid state batteries could be seen as everything we're looking for from an electric car battery, improving on all the fundamental characteristics needed for electric mobility. Unfortunately, we probably won't be seeing them any time soon. The latest estimations reported by Automotive News...

How Does Your New Car Get Better MPG Than Your Old One?Almost every day we hear of a shiny new car that gets a certain number of miles to the gallon, a number often greater than its predecessor. It sometimes seems like witchcraft - until significant steps towards high-tech materials are taken, rarely do cars lose weight from one model to the next (with...

Audi Urban Future Initiative: Smaller, Smarter, Autonomous, Linked CarsPut a group of urban planners, architects, and sociologists on a panel to discuss transportation in the cities of the future, and you may find they don’t spend much time talking about cars. Instead, you get statements like, “The megacity of the future desires to be a generous knowledge...

Txchnologist: Thorium lasers: Thoroughly plausible for nuclear carsSome proposed technological innovations seem so far out that they are easy to reject out of hand. But sometimes, a new idea has a kernel of plausibility. Such is the case with a new project to develop a thorium laser power generation system that its creator says could provide electricity for the...

With the 2011 Frankfurt Auto Show less than two weeks away the German auto industry is starting to really crank out the concept cars. Latest in the onslaught of new German metal is the Audi A2 concept. If you think the name sounds familiar then you aren't wrong. Audi launched a production A2 subcompact back in 1999. It was never sold in the U.S. and sales were slow in Europe thanks to a relatively high price, but technologically it was far ahead of its competitors and in many respects, still is today. With a lightweight and incredibly aerodynamic aluminum body and small, economical engines...

BMW Turns Heat Energy To Electricity To Boost Fuel EfficiencyTo increase gas mileage, carmakers can use smaller engines that produce the same power from less fuel. But they can also work to recapture part of the 70 percent of fuel's energy content that internal combustion engines waste in producing heat, noise, and momentum that has to be halted via braking...

NASCAR Stars Go Green In Chevy Volts... Off Track, At LeastFour-time NASCAR Sprint Cup champion Jeff Gordon and five-time champ Jimmie Johnson might earn their living in gas-guzzling V8 Chevy Impalas, but on the roads it's a different story. In contrast to the champions' high-octane lifestyles, on a day off you're more likely to see them cruising around...

Brewing Hybrid Battle: Is One Electric Motor Better Than Two?The word "hybrid" means many things. It can be interpreted as "high gas mileage," or "annoying leftie smugmobile," or--by engineers--an automotive powertrain that uses two different sources to generate the torque that moves the car. But among "full hybrids"--those powertrains that can move the car...

Remember GM's Autonomous Pod Cars? GPS Has To Catch Up FirstWe've always been intrigued by the EN-V autonomous pod cars proposed by General Motors. Maybe they harken back to the happy futurism of the Fifties, or maybe it's just that they're the first total reinvention of wheeled personal transit in quite a while that makes inherent sense. Prototyped more...

Electric Cars In "No Benefit For Poor Communities" ShockerPresumably following studies on whether bears really do defecate in the woods and to which religion the Pope actually pertains, The Greenling Institute in California has released a new report suggesting that expensive electric vehicles aren't benefitting communities of low income. The new study...

F1 television rights boss Bernie Ecclestone has never been one to mince his words, and now his ire has turned towards the 2014 Formula One rules that will require pitlane travel to be entirely electric. Adding to comments made about the lack of sound produced by regular electric vehicles, Mr Ecclestone commented: “There’s no way that it will be electric in the pit lane... People could be killed because they won’t hear the cars coming.” The 2014 rules will bring about a downsize from the current screaming 2.4-liter V8s to a more environmentally friendly 1.6-liter V6...

Should Detroit Dial Down The Doom & Gloom Over High-Mileage Rules?We've heard this script before. Some agency of the Federal Government proposes a new rule that will affect the design and performance of cars in some way, sometime in the future. Instinctively, reflexively, automatically, viscerally, the industry lashes out. Horror, catastrophe, misery, bankruptcy!...

'Flow Cells' May Let Electric Cars Recharge With Liquid RefillsJust two months ago, we published an April Fool's piece about a fictional new BP cell research project that would allow battery packs to be refilled at fuel station pumps. Truth is stranger than fiction, truly. Yesterday, the Massachusetts Institute of Technology described a nascent research...

New Chrysler Engine To Burn Gas And Diesel--At The Same TimeYou probably drive a gasoline car. And surely you've heard of cars with diesel engines. But how about a car with an engine that burns both fuels, at the same time? That's what Chrysler is working on, it turns out, funded in part with research dollars from the U.S. Department of Energy. Author Mike...

You may have other plans for Sunday than attending the Conference on Lasers and Electro-Optics in Baltimore. But if you were to sit in, you would hear a paper by a research team in Japan and Romania that offers a fascinating new avenue for increasing engine efficiency and reducing gas consumption: Ditch the spark plugs, and use lasers to ignite the fuel-air mixture. Previously, lasers that could deliver sufficient power to ignite a fuel-air mixture were so large as to be impractical for use in an automotive engine--and also relatively fragile. The team will report that it has developed new...

Does The Future Of Electric Cars Lie In Capacitors?Back to the Future may have been right: The cars of tomorrow will be powered by capacitors (they will not, presumably, be able to time-travel). At least, that’s what Tesla CEO Elon Musk said at yesterday’s Cleantech Forum in San Francisco, unleashing a torrent of speculation that the...
