Volkswagen will eliminate the last of its naturally-aspirated engines as models are refreshed or redesigned.

KLD Energy Technologies says its redesigned motor and battery pack will improve efficiency.

Nissan announced Tuesday that it will build an autonomous car by 2020. It is not the first carmaker to make that promise, but Nissan is hoping that a car that doesn't rely on connectivity could be what makes autonomous driving a reality.

Electronic sensors don't occupy a huge amount of space in electric car battery packs, but conversely, making sensors smaller could make the packs themselves much more compact. According to the MIT Technology Review, the U.S. government’s Advanced Research Projects Agency for Energy (ARPA-E)...

It takes customers a little while to get used to any new vehicle, but for new vehicles like the BMW i3 and upcoming BMW i8 sports car it could take a little longer than most. As electric vehicles, and uniquely-styled and equipped ones at that, there's plenty to learn. Just how do the cars work?...

Sometimes, you just can't make them up. A small Chinese electric car firm is currently seeking permission to name its new electric car technology 'Snowden'--named for the former U.S. intelligence contractor now in political asylum in Russia, after leaking top-secret mass surveillance details to the...

It seems strange that Audi has so far failed to capitalize on the huge success of its R18 e-tron quattro endurance racing cars. They're without doubt some of the most technologically-advanced race cars of the modern age, yet the Ingolstadt automaker has made only token references to the R18 with...

Companies that convert regular gasoline cars to electric, or add a plug-in option to regular hybrids, are nothing new. The same can't be said for companies taking electric cars and turning them into range-extended electric vehicles with small gasoline engines--but that's exactly what Hyperdrive...

Some of the most exciting hybrid technology isn't coming from Japan or the U.S. these days, but France. The PSA group, comprising Peugeot and Citroen, has already attracted plenty of attention for its hybrid-air technology. Now, it's looking for ways of improving the batteries in "micro hybrid"...

The humble automatic transmission has come along in leaps and bounds over the year, and modern systems are often more efficient than their manual equivalents. For the manual gearbox itself, economy is still very much down to "the nut behind the wheel", so anything that optimizes a driver's shift...

Among the many advocacy and lobbying groups that weigh in on automotive and energy policy matters in our nation's capital, Secure America's Future Energy (SAFE) isn't necessarily among the most high-profile. But now the group is offering something that should make civilians sit up and take notice...

Fuel cells are often considered a significant part of the future energy mix, though that future always seems to be a few decades away. That's partly down to the inefficient and rarely particularly green methods used to produce hydrogen, but it's as much about the cost of developing fuel cell...

The puzzle is almost complete: General Motors and Honda have signed an agreement to work on the future of fuel cell technology. They're the latest large automakers to announce a fuel cell technology share agreement, as car companies continue to explore the future of alternative propulsion. GM and...

There's a fairly good chance that, over the next decade or so, an increasing proportion of cars will use micro and mild hybrid technology. That means sourcing batteries with good energy density, lifespan and potential for recycling will become ever more important--and a battery consortium aims to...

Noticed engines getting smaller recently? You're not alone. "Downsizing", as it's called, involves using a smaller engine to do the work of a larger alternative--usually through turbocharging--while enjoying the fuel efficiency benefits associated with its size. Engineering firm Ricardo thinks this...

Visit any European city, and you'll be struck by an unfamiliar sound: That of engines, previously silent, re-starting on every green light. A large number of cars in Europe now feature stop-start technology as standard, and while EPA mileage figures aren't favorable to its effects, they're starting...

Smaller, more efficient engines better matched to more complex transmissions will have some of the biggest effects in making tomorrow's cars more fuel-efficient. The 2025 corporate average fuel economy (CAFE) level of 54.5 mpg translates to about 42 mpg on the EPA window sticker. And while Toyota...

No, we won't all be driving golf carts. In fact, as cars change over the next 12 years to meet much tougher fuel-economy rules, automakers will likely do their best to keep the changes invisible. Your next vehicles will deliver better gas mileage than ever before, no matter how large or small they...

It's pretty easy to take regenerative braking for granted, these days--virtually every electric and hybrid car on sale uses it to some extent. Maybe we should be a little more appreciative of its benefits, as Ford estimates owners of its vehicles have saved 100 million gallons of gasoline over the...

If it wasn't so important for the future of electric cars, it could almost get tiresome: Just how do you improve batteries for longer life, quicker charging and a greater range? It's a question being investigated by great minds all around the world, and has turned up some surprising and exciting...
