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...

It's long been an inspiring futuristic concept: electric cars that can recharge continuously at speed, driving along roadways with built-in inductive charging. Think a modern-day version of slot cars, but at 1:1 scale. Now French automaker Renault has demonstrated a prototype of just such a system...

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...

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...

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...

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

Tesla may have taken capabilities out of the Model S and Model X because of a supplier switch.

A Tesla video shows what self-driving cars "see."

Exxon researched hybrid cars in the 1970s, then ignored them.

Apple may be eyeing a new configuration of lithium-ion battery cell for its rumored electric car.

Apple and Google are both experiencing setbacks in their plans to build autonomous cars.

Elon Musk says the reconfigured Autopilot system announced over the weekend could have prevented the fatal crash that took place in May.

NASA research may be relevant to the Tesla Autopilot debate.

Infiniti is likely the first carmaker to put a variable-compression engine into production.

The Audi eROT system recovers energy from the movement of a car's suspension.
