Audi's 'tron' program has been, well, a little confusing over recent years. Back in the early days it was oh so simple--one concept car, known simply as the Audi e-tron, represented Audi's foray into future mobility. Since then it seems a dozen models have come and gone, but after presentations...

Is KERS an energy-saving technology we'll be seeing in production cars any time soon, or is it just a way to help increase performance? We've been to Sweden to find out at Volvo's Gothenburg test track.

The dispersal of automobiles is quite an uneven one. For every three or four-car household in the developed world, there are huge swathes of land in developing countries without access to any sort of motorized transport however badly they may need it. One British entrepreneur hopes to change that...

Not all hybrids are created equal. In fact, several different types are sold throughout the automotive industry, all offering varying economical benefits and priced at varying levels. Technology and innovation firm Johnson Controls Inc. suggests there's room for even more, and the next big thing in...

Drivers of the Tesla Model S are generally pretty happy with their cars, but as with any new product there are always a few ways it could be improved. Tesla Motors [NSDQ:TSLA] is one of few companies that can execute those improvements without you having to lift a finger, as software updates can be...

The Chevrolet Spark, the smallest Chevy sold in the U.S., will get some mechanical changes next year, according to Christi Landy, the brand's small-car marketing director. The 2014 Chevrolet Spark, which will go on sale late this year, will offer a continuously-variable transmission (CVT) in place...

When automakers test prototypes and new technologies, it's often done under the skin of an existing vehicle--partly to save costs, partly to avoid the gaze of prying spy photographers. That's why the Ford Fiesta you see here looks nothing special, save for some basic wheels and its not-for-U.S...

Volkswagen chairman Prof. Dr. Martin Winterkorn covered virtually every area of green technology in his talk at the recent Vienna Motor Symposium. Plug-in cars, natural gas vehicles, diesels and a new ten-speed dual-clutch transmission were all discussed, pointing to a bright future for...

If you follow Formula One racing, you'll have heard of KERS, or Kinetic Energy Recovery System. There are several techologies being used, but among them is flywheel KERS, using a spinning flywheel to capture energy which can then be used at a later time. Volvo has been trialing such a system for...

It should be fairly obvious, but apparently it isn't: Plug-in electric cars are not going to sweep the marketplace overnight. Their sales will grow slowly and steadily from a low base. U.S. plug-in sales in 2012 tripled over the previous year, and most projections are that they'll double again this...

The benefits for dedicating an electric motor to each wheel of a vehicle were clear to see in Drive's recent video of the Mercedes-Benz SLS AMG Electric Drive. Make those motors in-wheel units, and in theory you get even more benefits. It's a design that in-wheel motor company Protean has been...

The modern automotive business is a funny thing, making bedfellows of the unlikeliest of couples. Ford and General Motors don't collaborate often, but when they do it's usually on a transmission. This tradition continues as both companies announce an agreement to co-develop new 9- and 10-speed...

Many people imagine that fuel efficiency stops and starts with engine technology and driving technique, but there's a little more to it than that. Making a fuel-efficient vehicle involves a holistic approach that examines every aspect of a car's design and tries to reduce its impact on fuel...

History makes fools of us all sometimes, none more so than when we dismiss certain ideas out of hand, only for them to come back years later and eat our words. That's why we're always intrigued by companies claiming to reinvent the engine. One of them might well do so, given the right resources...

Volvo doesn't sell any diesel vehicles in the U.S, but if and when it decides to change that it'll certainly have some of the more advanced units on sale. The company's new diesel engine family, launched this fall in Europe, features what Volvo calls 'i-ART' technology to help cut fuel consumption...

The 2013 Formula One racing season is already underway--and already causing controversy--but from an engineering standpoint much of the focus is already on 2014. That's because from the start of next season, new engine regulations are set to significantly improve the cars' fuel efficiency, and...

The rate at which technology develops makes predicting the future incredibly difficult, but people get it right sometimes. They get it wrong sometimes too, and you'd have found a mixture of both in the April 3, 1988 issue of the Los Angeles Times Magazine, which peered 25 years into the future--to...

Most people give them little thought, but tires are one of the most important components on a car. They are, of course, your only point of contact with the road. So ultimately, tires are responsible for everything from performance, through cornering, to efficiency and noise. Tires of the future...

It's both exciting and frustrating living in the current automotive age. Exciting, because we're truly seeing an eclectic mix of powertrain technologies being developed, the fruits of which we're increasingly able to drive. And frustrating, because there's still no surefire way of knowing what...

As the Geneva Motor Show finally closes its doors to the public, many will go home lusting after the LaFerrari or McLaren's P1 hypercars. For others though, the show's indisputed star was the production Volkswagen XL1--as thoroughly engineered to be economical as the others are to be fast. While VW...
