Gas Mileage

As long as the internal combustion engine has existed, engineers have been trying to find better ways of igniting the highly combustable mixture of air and gasoline that powers cars. Everything from higher voltage coils through to electronically-timed ignition and making spark plug tips from metals...

The Ford Escape Hybrid was not only the first U.S.-built hybrid electric vehicle, it was also the first hybrid sport-utility vehicle--or crossover, if you prefer. It's had a good run, starting in the fall of 2004 and continuing through the 2012 model year. As of the end of September, Ford has sold...

The 2013 Ford Escape, the first entirely new design in more than a decade for its popular compact crossover, will be officially unveiled next month at the Los Angeles Auto Show.

The 2012 Buick Lacrosse with eAssist is now beginning to roll into dealerships across the country, and we've been curious to see how GM would market the car. On our preview drive this spring of a prototype Lacrosse with eAssist, we noticed that the dreaded H-word (hybrid) had been virtually...

Engines might be getting smaller in the pursuit of saving fuel but transmissions are going the opposite direction. Over the last few years different carmakers have rapidly increased the number of ratios available to drivers, with Mercedes-Benz giving us 7-speed autos, Lexus developing an 8-speed...

You’re probably already familiar with the effect that a hybrid drivetrain has on fuel economy, but now one of the key concepts of a hybrid drivetrain -- the ability for the engine to turn off and on automatically at stoplights -- is being introduced in conventional gasoline-engined cars...

Kia has priced its 2012 Rio Hatchback, which gets 40 mpg on the highway and comes standard with start-stop, to start at a base price of $14,350.

Remember $4 gasoline? It was just last May that gasoline soared to an average price of $4 per gallon across all U.S. markets, with even the cheapest pumps showing prices of $3.50 or more. What a difference a few months makes. Gasoline has now fallen below $3 a gallon in a handful of areas...

Almost every day we hear of a shiny new car that gets a certain number of miles to the gallon, a number often greater than its predecessor.

Yesterday, auto dealers met with their members of Congress to try to delay new rules that would stiffen the gas-mileage requirements for cars sold in model years 2017 to 2025. The National Auto Dealers Association made the rounds to pitch a proposal that would amend spending legislation for the...

For many people, the purchase of a fuel efficient car is usually made to save money on driving, as the cost of being a car owner rises further and further. That being the case, why buy an expensive car in the first place, potentially taking years longer to pay off the fuel savings? The good news is...

Reading eBay auction listings, it's important to look at the disclaimers. Such as ...

OK, so now that...

There are many ways of making a vehicle more fuel efficient. Improvements in engine technology, materials, rolling resistance and aerodynamics can all contribute towards making a car easier on gas than its predecessor. How about making it quieter? You may think making a car quieter at speed might...

It's not always true that the smallest cars get the best gas mileage. In many cases, compact cars get mileage equal to or better mileage than their shorter, stubbier subcompact brethren. The new 2012 Chevrolet Sonic subcompact has managed to crack the magic 40-mpg highway mark, though. Estimates...

While Toyota is still struggling to get itself entirely back to normal after the devastating March 11 earthquake and resulting tsunami, the company has a number of new green cars coming along this autumn. It is pulling forward the launch for the redesigned 2012 version of its best-selling Camry...

The...

The 2011 Mazda2 is already one of the most fun small cars on the market, sharing its platform with Ford's Fiesta. It's pretty economical too, but with Mazda's next generation of gasoline engine, it'll become very efficient indeed. The 1.3-liter Skyactiv-G unit soon to be found in the Mazda2 gets 30...

Volvo isn’t the largest automaker in the world -- but it is one of the safest thanks to a long-standing passion about passenger and pedestrian safety dating back to when the company was founed nearly 85 years ago. But recently Volvo has developed a new passion to put alongside its aim to have...

It's one thing Honda not sending its new Brio minicar over to the United States, so economy car fans are unable to sample its 52 mpg delights. That would all be okay if we found out it was a terrible car, but unfortunately for us, the first reviews coming from overseas are singing its praises. One...
