Range-Extended Electric Vehicle

The 2011 Chevrolet Volt is a remarkable achievement for General Motors, but it does have a few features and behaviors that make us scratch our heads. After living with the car for five days and more than 700 miles, here are five questions we'd love to get answers to. (GM PR: You know where we live...

We're going to have a lot of 2011 Chevrolet Volt coverage this week, as we round up our impressions on the five days and hundreds of miles we've racked up on GM's first extended-range electric vehicle. We'll do a full drive report later on, but first, a few quick hits about the things we like in...

It all started when General Motors CEO Dan Akerson said the company wanted to "double" production of the 2011 Chevrolet Volt, its range-extended electric car. Various media outlets reported the news with varying degrees of accuracy. So far, GM has not officially said it will make more Volts...

If Consumer Reports didn't exist, someone would have to invent it. It may be the most trusted brand in evaluating cars, and it offered reliability ratings well before J.D. Power became a household name. A bad rating can send auto execs crawling to its doors to learn what they need to change to get...

A few months ago we asked the question, what exactly do you have to service on a 2011 Nissan LEAF? After all, the LEAF doesn't even contain many of the items that require regular attention on a regular car, such as oil changes, spark plugs, filters, transmission fluid and muffler parts. Brakes...

Soon you will be able to do away with those pesky charging cables for all your portable devices when driving as Powermat, a pioneer in wireless charging technology, is developing new technology that will essentially turn your car into a charging port for your mobile phone, MP3 player or handheld...

General Motors announced today that it has licensed lithium-ion battery technology developed at Argonne National Laboratories, the research institution that's funded largely by the U.S. Department of Energy. The agreement allows GM to use the technology throughout its supply chain, and covers a...

Much of 2010 was spent learning more and more details about Chevrolet's exciting new range-extended electric car, the Volt. Towards the end of the year our colleagues at GreenCarReports finally got to drive the vehicle, and more recently the first owners have taken delivery. So what do owners...

If the idea of measuring the efficiency of an electric car, which burns no gasoline, in miles per gallon still irks you, spare a thought for our green car expert John Voelcker who goes to some length in this previous article to try and explain why the EPA deems it fit to do so. While that previous...

We've loved the concept of the Audi A1 e-Tron concept since its launch at the 2010 Geneva Motor Show last March. It's a range-extended electric vehicle (like the 2011 Chevy Volt) that uses a tiny Wankel rotary engine to run a generator that produces electricity to power the car once its lithium-ion...

The 2011 Fisker Karma is still on track to reach U.S. dealers in March or April, according to the company. But there's one new piece of info: The price of the extended-range electric sports sedan has gone up. Again. Originally announced in 2008 at a price of $80,000, the Karma fairly quickly went...

With the handful of new production intent concept cars Lotus showed off at the recent 2010 Paris Auto Show, it’s evident the automaker, typically focused with lightweight sports cars, is trying new things. What’s interesting to see is that Lotus is expanding towards both ends of the new...

For next month's Detroit Auto Show, we're making our list and checking it twice. But it turns out that one notable name in green cars is giving the country's largest auto show a miss. Fisker Automotive confirmed to GreenCarReports yesterday that it won't be present at the 2011 Detroit Auto Show...

Production of the world's first range-extended electric car is now a reality. Today, the first shipment of 2011 Chevrolet Volt electric cars left the Detroit-Hamtramck assembly plant. The cars are bound for dealers and buyers in the initial launch markets: California, Texas, New York, and...

We don't hear much about the 2011 Chevrolet Volt's half-brother, the Opel/Vauxhall Ampera, here in the States. But in the U.K., the president of GM Europe laid out that group's plans for future generations of Ampera--and they're significant for what they say about upcoming models in an expanding...

The shenanigans continue. Just this week the Nissan LEAF was rated at 99 mpg-equivalent by the EPA, raising the ire of our own John Voelcker--and justifiably so. Today, the Volt gets similar treatment and a similar rating, but only in EV mode. Add in the gas-only mode's 37 mpg rating and the...

If you're familiar with the 2011 Chevrolet Volt range-extended EV, then you're already familar with the Opel Ampera, since it's essentially the same car. The Ampera will be sold under General Motors' other brands, the Germany-based Opel and in the U.K. as the Vauxhall Ampera. It's not uncommon for...

As we noted yesterday, we'll be giving one brand-new 2011 model the GreenCarReports 2011 Best Car To Buy Award in conjunction with the Los Angeles Auto Show next week. We'll summarize each of our five nominees, one per day, between now and then. To avoid any bias, we're doing the list in strict...

For the next few years, the 2011 Chevrolet Volt range-extended electric car will be the sole focus of GM's advanced powertrain efforts for U.S. car buyers. But that hasn't stopped it from putting battery electric cars into production elsewhere in the world. Electric minicars in China Last week, in...

Internal-combustion engines typically convert only one-third of the energy stored in gasoline or diesel fuel into usable power. The rest is wasted as heat, noise, or even goes unburnt. So the question for designers of range-extended electric vehicles becomes: How can onboard liquid fuel most...
