Range-Extended Electric Vehicle

Mazda has revealed its first "mass production" EV at the Tokyo Motor Show; more on a rotary range-extended version is to come later.

The first electric car from Mazda is mere months away, although a U.S. timeline hasn't yet been confirmed.

The Wankel rotary, the peculiar pistonless internal combustion engine design that Mazda built so much of its heritage around, may see a resurgence after all. Earlier reports and remarks from Mazda executives have suggested that while the rotary will make a comeback, it will be relegated to...

Electric trucks are getting more attention now than they did eight years ago, as the world prepared for the launch of the first modern electric cars to be sold in volume. The Tesla Semi tends to draw enormous amounts of attention, while less glamorous fleet buyers are ever more favorable toward...

As more battery-electric cars are sold and more drivers become aware of them, the question of battery life recurs among pretty much every potential buyer. How long will the battery last? Will I have to replace it every 18 months as I do in my smartphone? Data on the liquid-cooled battery packs of...

While the 2018 BMW i3 will formally debut next week at the Frankfurt auto show, the company has released details ahead of time on the updates to the lineup of its compact electric car. While battery range stays the same as last year, a new i3s model (for Sport) has been added, with revised...

The 2018 Karma Revero remains as much of a head-turner today as the low, sleek four-door sedan was when it debuted a decade ago under another name.

Recent patent filings suggest Mazda’s next Wankel engine will equip a battery-powered car, not a rear-wheel drive heir to emblematic sports coupes like its RX-7 and RX-8. Mazda has invested more time and money into the rotary engine than any other automaker, so executives are reluctant to let...

Unlike conventional hybrids and many plug-in hybrids, the first-generation Chevrolet Volt makes extensive use of both electric and gasoline power. With a fully-charged battery pack, it will drive on electric power alone until the charge is depleted, at which point the onboard gasoline engine...

Advocates of battery-electric and hydrogen fuel-cell cars are often at odds over which powertrain technology is the more practical solution to reducing emissions. But French firm Symbio continues to experiment with ways to combine the two. It fits hydrogen fuel cells as range extenders for...

The 2017 Karma Revero (nee Fisker Karma) was formally unveiled to the public and to Fisker owners tonight at an event in the canyons of Laguna Beach, south of Los Angeles. Executives of the company formed from the bankrupt wreckage of Fisker Automotive pledged that they've fixed the car's 2012...

The BMW i3 electric car may be the most ambitious small car of recent years, bristling with new technology and innovation. Its carbon-fiber reinforced plastic body shell rides on an aluminum platform, and its all-electric powertrain may include an optional small engine. The battery-electric i3 also...

The 2017 BMW i3 may be offered with two battery-pack options.

The BMW i3 is the only electric car in the world sold with an optional range-extending engine to increase driving capability beyond the range provided by the battery. The "REx" option adds a small, 34-horsepower 650cc two-cylinder engine, derived from one used in BMW motorcycles, that powers a...
