Gas Mileage

The 2015 Fiat 500 gains new technology features, and an automatic transmission for Turbo and Abarth models.

Auto writers tend to like Mazdas; they generally perform and handle well, and are far more fun to drive than the anodyne Fords, Hondas, and Toyotas that outsell them in the compact and mid-size categories. The newest crop of Mazda cars and crossovers, built around the company's highly...

Smart ForTwo city cars are apparently quite easy to tip over.

Ever since the first Honda Insight and Toyota Prius arrived on U.S. shores, hybrid vehicles have been among the most efficient vehicles on the road. The latest Toyota Prius is rated at 50 mpg combined by the EPA, a figure that only plug-in vehicles currently top. But in other countries, the Prius...

The trend of increasing average fuel economy continues.

With highway economy of 36 mpg, the 2015 Chrysler 200 isn't the most fuel-efficient vehicle we've written about recently, but it has an important job to do. The old model, despite being widely loathed by anyone forced to rent one at airport desks around the country, sold in large numbers in the...

Is it possible to make a gasoline engine so efficient that it would emit less carbon dioxide per mile than is created by generating electricity to run an electric car over that same mile? Small Japanese carmaker Mazda says yes. In an interview published last week with the British magazine Autocar...

If ever any car brand should have offered a hybrid before now, it would be Subaru. Now we've driven the 2014 Subaru XV Crosstrek Hybrid, its very first hybrid offering. It's a much better car than the Crosstrek on which it's based, but little of that improvement has anything to do with the hybrid...

How do you measure your gas mileage? Do you take mileage readings after each tank, refill to the brim, calculate how much you've used...and repeat at each fill-up? Or do you press the trip computer button a few times to bring up your tank average? If you're doing the latter, there's always the risk...

The 2014 Mitsubishi Mirage is unusual among the latest breed of gas-sipping small cars. There are no fancy tricks employed to hit its 37-40 mpg combined EPA ratings, no turbochargers or hybrid systems. It's simply small, light, aerodynamic and uncomplicated. Those qualities are also allowing...

U.S. mass transit usage continues to grow, while car usage remains stagnant.

Taking the average passenger car and making it more efficient is the combination of dozens of factors from engine technology to aerodynamics to more extreme measures like hybridization. But some factors you just can't control, like traffic, weather and the changing of traffic signals. ALSO SEE: Is...

The 2015 Ford Mustang has a tricky job to do. Not only must it impress fans of previous Mustangs, but as sales expand into Europe it must become more efficient too. To that end Ford has installed a four-cylinder engine for the first time in many years, but it's also worked on aerodynamics--such as...

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...

Honda will end sales of the CR-Z and Insight hybrids in Europe.

The 2015 Ford Expedition full-size SUV will be offered exclusively with a 3.5-liter EcoBoost V-6.

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...

The Toyota Corolla has long been the best-selling compact sedan in the U.S., and the all-new 2014 Corolla is a considerable advance over the aged, grim, unexciting model it replaced. We recently tested the most fuel-efficient model, the Corolla Eco, over our usual test route of about two-thirds...

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...
