Tesla Motors CEO Elon Musk confirmed that a press event to be held this Thursday evening will demonstrate battery-swapping for the Tesla Model S. The mode of communication was his favorite medium: a tweet. "Seeing is believing," wrote Musk, saying that the company will do a live demonstration of...

Hybrids and plug-in electric cars probably get more press than they deserve, given how small their numbers are in the vehicle fleet. The U.S. has roughly 250 million vehicles on the roads, of which less than 2 percent are hybrids and plug-ins of all kinds. Nonetheless, both technologies are...

Tesla Motors announced this morning that it will conduct a partial recall of Model S electric sedans manufactured between May 10 and June 8 of this year to fix a potentially weakened left-rear seat attachment striker bracket. According to a post on the company's website and signed by CEO Elon Musk...

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...

We'll start with the bad news: No, Audi definitely won't be producing any more examples of its R8 e-tron electric supercar. And even if it did, it'd be well beyond the reach of mere mortals--rumor has it that each of the ten e-trons currently in existence have set Audi back around $1.3 million. All...

The Toyota Corolla has been the most popular compact car in the U.S. for more years than we can count. But this year's model is the oldest model in a category that has seen every one of its competitors refreshed in the last three years. The new 2014 Toyota Corolla, the 11th generation of a...

Paul Scott may be one of the most dedicated electric-car advocates around. He sells Nissan Leafs for a living, and helped found advocacy group Plug-In America. A few weeks ago, he had a brilliant idea. Scott used a significant chunk of his life savings for a ticket to a pricey Barack Obama...

Plug-in car sales continued at a steady pace in May, with early estimates of perhaps 6,500 to 7,000 sold overall. As always, precise figures are impossible because Tesla Motors [NSDQ:TSLA] does not report monthly sales as every other carmaker does. We'll refine our totals as more reports come in...

Does the supposedly clean, green Tesla Model S really pollute more than a gas-guzzling Jeep Grand Cherokee sport-utility vehicle? That's what one analyst has claimed. In an exhaustive 6,500-word article on the financial website Seeking Alpha, analyst Nathan Weiss lays out a case that the Model S...

If you’re still smitten with the design and styling of the Smart Fortwo, you’re probably going to be happier with the version that never needs a gas station. That’s the conclusion we emerged even more confident about, after the hour earlier this month we spent with the Smart...

It’s not every day Chevrolet executives talk about launching at car that competes directly with … a Volkswagen. The new 2014 Chevy Cruze Diesel, however, aims directly at the only affordable compact four-door sedan with a diesel engine sold in the U.S. until now: the Volkswagen Jetta...

The new 2014 Chevrolet Impala is a big five-passenger family sedan, the largest one Chevy sells. While it was launched earlier this year with a 303-horsepower 3.6-liter V-6 engine, it can now also be ordered with a 196-hp, 2.5-liter four-cylinder Ecotec engine that produces 186 lb-ft of torque...

Many things can signify summer--the weather finally being warm enough to ditch those outer layers of clothing; TV ads taking a distinctly more cheery tone; maybe simply hunting around for your sunshades for the first time in six months. It's now possible to have fun in the sun and get good gas...

Today marks my first anniversary driving a Better Place Renault Fluence ZE battery-electric car. So it seemed appropriate to summarize my experience to date with the Better Place service, which has had some challenges but is still very much in operation. I paid around $45,000 upfront for my car and...

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.

I've been leasing a 2011 Chevrolet Volt for almost two years now. And about three months ago, I took delivery of a 2013 Tesla Model S, the 60-kWh version. So I've gotten an extended first-hand look at arguably the two most technically advanced production cars in the U.S.--and the two best-selling...

It often takes awhile to get gas-mileage ratings onto the EPA's official website, and it's no different with electric-car efficiency numbers. Now we have the final ratings for the 2013 Nissan Leaf compact hatchback: It's rated at 115 MPGe, up from the 99 MPGe for 2011 and 2012 models. MPGe stands...

After our quick drive of a 2013 Nissan Leaf before the New York Auto Show in late March, we were finally able to spend some extended time with the updated electric car outside Nashville. Our initial impressions remain the same: The Leaf is a perfectly normal, competent compact five-door hatchback...

Your mileage may vary. We've heard it for years, we all know it's true, and yet we put our trust in the EPA's fuel-efficiency ratings as a guide to what kind of gas mileage a car will really get. Now, two cars--the 2013 Ford C-Max Hybrid and the 2013 Ford Fusion Hybrid--have brought the failings of...
