It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power electric cars can be quite complex to fabricate. So, what is there to know about rare-earth...

The Smart Vision EQ Fortwo wants to be a self-driving electric matchmaker. Ahead of its global unveiling at the 2017 Frankfurt Motor Show, Smart on Wednesday took the wraps off of an urban-oriented, self-driving electric concept car that can supply power back to the grid when it's not in use and...

Alkaline batteries have been a staple energy source for decades, but their potential has been capped by their chemical properties. Notably, alkaline batteries cannot be recharged, which means their application is often limited to single uses in small devices such as flashlights and remote controls...

Continental, a major supplier for automakers around the world, has come out with a bold prediction: internal-combustion engine development by German automakers will essentially end by the year 2025. The supplier, which makes exhaust-gas-cleaning systems for diesel cars and nitrogen oxide-measuring...

It's a technology that's been a sort of Holy Grail in the auto industry for at least a couple of decades. Now Mazda, one of the smallest global automakers, plans to introduce it in a radical new engine to be used in a future Mazda vehicle in 2019. It's called homogeneous charge compression...

One of the greatest challenges faced by modern electric cars is the vehicle's range, which is largely proportional to the energy capacity of the battery. Range anxiety often keeps buyers out of electric cars and in their fossil-fuel powered counterparts. Most of the attention given to solving the...

Six years ago, we wrote that a number of single-motor hybrid systems were about to enter the market. They represented a new approach to a technology pioneered in 1997, when the first-generation Toyota Prius was launched in Japan. Through 2010, all the full-hybrid vehicles introduced by Ford and...

It seems every other day Tesla CEO Elon Musk has news about the next big project for the electric-car maker. This time, the news is about a project that seems relatively achievable, but one that produces as many questions as it answers. According to reports, Tesla is looking into starting its own...

While many drivers generally understand the concept of an electric car, understanding generally stops there. It's a car, and you plug it in to get power to run it. That's fine as far as it goes. Beyond that, things get hazy pretty quickly, we've found. DON'T MISS: Plug-in hybrid problem: buyers...

The challenge of reducing the energy used by traditional heating systems in battery-electric and plug-in hybrid cars is one automakers still grapple with today. Reduced battery range in cold temperatures, combined with batteries working overtime to heat the cabin, can produce drastic declines in...

Electric vehicles aren't always associated with speed and performance, but researchers at North Carolina State University may have discovered a breakthrough to change those qualities inside their batteries. Of all things, water may hold the key to faster electric-car battery technology. Researchers...

Last year, techies, auto journalists, and Apple fans spent a great deal of time debating the existence, technology, and potential prospects of an "Apple car" project that the company never officially acknowledged. The idea that Apple would move from fast-turn, high-volume, very profitable consumer...

Large auto companies are likely aircraft carriers: it takes a long time for them to change direction, and far longer yet to get them aligned on a new course. To various degrees, the world's carmakers have started to produce and sell vehicles that plug-in, whether for some or all of their travels...

Some are almost unnoticeable, others make the car shudder each time they activate—but start-stop systems are here to stay. First rolled out in Europe and Asia, where crowded city driving requires cars to spend more time at a standstill, they switch off the engine when the car's not moving...

It's been a vision of the future for decades now: self-driving cars that let you get in, specify your destination, and then curl up for a bit more sleep, waking when you arrive. That kind of anywhere-any-time autonomy remains some years in the future, most engineers suggest. Automakers are already...

Could a full-size pickup truck ever get a fuel-economy rating of 37 mpg? California-based Achates Power believes it can, and its novel engine uses a design that dates back to the earliest days of internal combustion to do so. The company announced its two-stroke, opposed-piston diesel engine for...

The differences between gasoline and diesel engines lie not only in their fuels, but in how those fuels are ignited. Gasoline engines use spark plugs, while diesels simply use compression. But it is possible to ignite gasoline in an internal-combustion engine with compression, as in a diesel. DON'T...

With news stories literally every day about autonomous vehicle tests, and the growing number of plug-in electric vehicles on sale, the future is ... well, up in the air. Readers of this site tend to be more future-oriented than many car buyers, so we polled our Twitter followers about their views...

Over the past six months, Toyota has made some remarkable decisions about its present and future car technologies. After years of staunch opposition to battery-electric vehicles, it committed to launching one by 2020. Now, the company has decided to offer its proprietary hybrid technology in volume...

The cost of electric cars and diesels will equalize around 2025, says one Volkswagen Group of America executive.
