If you're driving into rural areas to spend time with nature, there's nothing more noticeable than a bright yellow New York City taxi cab to do it in. A couple of months ago, we had a chance to test out Nissan's new "Taxi of Tomorrow" for New York City, based on its NV200 small commercial van--but...

Dozens of companies around the world will sell you devices claiming to improve your gas mileage. For what seems like a nominal amount, the magic devices can apparently increase your fuel economy by double-digit percentage figures. It seems too good to be true. And all too frequently, as Jalopnik...

The 2014 Ram 1500 EcoDiesel is already getting plenty of attention from truck buyers.

This year, the big hurdle for pickup-truck gas mileage was 20 miles per gallon combined--and two trucks made it.

The Obama Administration wants stricter truck fuel-economy rules to replace the current standards, which expire in 2018.

It's long been known that aluminum is an effective way of reducing the weight of vehicles, but Ford's adoption of the metal for its 2015 F-150 truck has finally spurred others into action in the pickup class too. General Motors has recently secured contracts with aluminum suppliers Alcoa and...

India's Bureau of Energy Efficiency has proposed increasing fleet-average fuel economy 14 percent in 2016.

You've read the reviews, and it's finally time: You're off to the dealer to replace your old car with a new, much more fuel-efficient vehicle. But then you get to the dealer, and during your test drive, you notice that the gas mileage shown on the car's display is nowhere near the EPA rating...

It's been expected for some time that the next generation Chevrolet Volt could use a smaller, more efficient and likely three-cylinder power unit as its range-extending engine. Now, we may be getting our first glimpse of that engine, in a more conventional installation than last year's Opel Monza...

For the first time in over 15 years, increased engine and transmission problems in 2011 model year cars have contributed to a decline in vehicle dependability in J.D. Power's annual Vehicle Dependability Study. Ordinarily you might put this down to the luck of the draw--an occasional drop is almost...

After several years of keeping quiet, Volvo is finally starting to roll out new and updated products--especially in its core mid-size segment. We've now driven three of them, all 2015 models: the XC60 crossover utility, the S60 sport sedan, and the new V60 wagon, the first actual Volvo wagon to be...

The third-generation MINI has only just been launched, but that hasn't stopped parent company BMW commenting on what the next generation might hold.

Citroen hasn't been seen on U.S. shores for many years now, but if its latest production vehicle is anything to go by, that's something of a pity. Called the C4 Cactus, it's Citroen's latest take on the compact crossover hatchback. Most comment will go to its unusual name and even more unusual...

Car sharing is more popular than many have previously estimated, the study's authors say.

Hybrid SUVs and crossover utility vehicles remain rare compared to the growing array of hybrid passenger sedans and hatchbacks. So we've been eager to test the new 2014 Nissan Pathfinder Hybrid, one of only four hybrid crossovers. MORE: 2014 Nissan Pathfinder Hybrid: Is It Hybrid Enough To Matter?...

Five years ago today, Green Car Reports began a daily publishing schedule. At first one a day, and then more, we wrote articles on fuel efficiency, hybrids, diesel vehicles, and the plug-in electric cars that were then still two years away from the market. Think back to February 2009, when the...

The first Volkswagen Beetle was imported to the U.S. in January 1949.

It's winter in the Northeast, and last week's Polar Vortex luckily came along just as our weekend test car was a 2014 Jeep Cherokee. This is the all-new compact crossover that replaces the old truck-like Jeep Liberty, going head-to-head with popular compact crossover utilities like the Chevy...

Yep, Big Oil is definitely scheming and plotting to destroy the electric car. Everyone knows that. Right? [sigh] Time for more mythbusting, it seems. The surprising success of our first debunking of five green-car myths led us to look at five more relatively common ideas and explain ... well, as...

MINI USA has announced pricing for the third generation of its BMW-produced hatchback, which will be priced from $20,745 when it arrives in the spring.
