Gas Mileage

Smaller, more efficient engines better matched to more complex transmissions will have some of the biggest effects in making tomorrow's cars more fuel-efficient. The 2025 corporate average fuel economy (CAFE) level of 54.5 mpg translates to about 42 mpg on the EPA window sticker. And while Toyota...

No, we won't all be driving golf carts. In fact, as cars change over the next 12 years to meet much tougher fuel-economy rules, automakers will likely do their best to keep the changes invisible. Your next vehicles will deliver better gas mileage than ever before, no matter how large or small they...

Your mileage may vary--but these days, it appears, your mileage may vary more than it used to. According to a new report, the gap between rated fuel efficiency and the real-world gas mileage achieved by actual drivers is increasing. In 2001, it notes, the average difference between rated gas...

Remind us in future to avoid drive routes confined almost exclusively to Manhattan. While they're great for showing off hybrid cars--including the 2013 Lincoln MKZ Hybrid we briefly tested on Tuesday--they take years off your life. We had a chance to put about 10 miles on the new hybrid MKZ, the...

Ford's updated Fiesta SFE is offering even better fuel efficiency for the 2014 model year. The Fiesta uses a 1.6-liter gasoline engine, developing around 120 horsepower. It's a fun little car to drive, but the main focus here is economy. With EPA-rated mileage figures of 30 mpg city, 41 highway and...

While the assembled hoardes drooled over Ferraris, Porsches and McLarens at March's Geneva Motor Show, those of a greener disposition were more interested in another vehicle. Launched alongside the hybrid hypercars was a true hybrid supercar in its own right--the plug-in diesel hybrid Volkswagen...

You want a four-seat car with the highest EPA combined gas-mileage rating you can get--but you've decided you don't want a hybrid. For 2014, two new competitors are joining the fray--and they seem likely to offer considerably better fuel efficiency than today's best-of-the-pack. This year, your...

The Toyota Corolla has been the most popular compact car in the U.S. for more years than we can count. But this year's model is the oldest model in a category that has seen every one of its competitors refreshed in the last three years. The new 2014 Toyota Corolla, the 11th generation of a...

Name one car convenience feature you absolutely couldn't live without, and it'd probably be air conditioning. Whether you live in a hot or cold climate its cooling and demisting benefits can't be understated--it has safety benefits as much as comfort and convenience ones. It also has an effect on...

It just keeps rising: Average gas mileage for new cars has once again hit a new high in the U.S. Statistics kept by the University of Michigan's Transport Research Institute (UMTRI) show sales-weighted MPG of 24.8 mpg in May. That contrasts with 24.6 mpg in March, and a rise from 24.5 mpg in...

Slowly, the economic recession is winding down and consumer moods are improving. Plus, today's new cars get better gas mileage than they did just a few years ago. Is this year the best time to buy a new car? According to several industry analysts quoted in The Detroit News, the answer is...

Every now and then, EPA gas-mileage ratings--and cars that notably fail to achieve them in real-world use--burst into public awareness. Hyundai and Kia had to agree to reduced ratings and send refunds to buyers after admitting to testing-procedure errors following an EPA investigation. But do...

Chevrolet has released details of its latest 2014 Malibu, set to go on sale this fall. Among the changes, the biggest news is that all Malibu models will get stop-start technology on the standard model--shutting down the engine when stopped to conserve fuel. Fitted to a new 2.5-liter gasoline...

From our earlier first drive of the 2014 Ford Fiesta ST over at Motor Authority, we already knew that Ford has put together not only one lean pocket rocket that's a hoot to drive, but one of the most compelling small cars from a value standpoint. With its 1.6-liter turbocharged EcoBoost...

The rate at which we use fuel even on an individual basis can be pretty surprising. If you do just 10,000 miles per year at 30 mpg, you'll use 333.3 gallons in a year. That's around 2,800 pounds, or the weight of a small compact car--the sort of car that'd do around 30 mpg in the first place. On a...

Many things can signify summer--the weather finally being warm enough to ditch those outer layers of clothing; TV ads taking a distinctly more cheery tone; maybe simply hunting around for your sunshades for the first time in six months. It's now possible to have fun in the sun and get good gas...

Is KERS an energy-saving technology we'll be seeing in production cars any time soon, or is it just a way to help increase performance? We've been to Sweden to find out at Volvo's Gothenburg test track.

It's an exciting time for diesel fans in the U.S, with automakers finally waking up to that section of the market that longs for great highway MPG and lots of torque. Most people already know the benefits of modern diesels, but there are a few general things that people may have missed. So in the...

Remember Elio Motors? If you're one of their 17,000 or so Facebook fans it'll be hard to forget, as the company's little green three-wheeled vehicle will be a regular fixture on your timeline. As The Detroit News reports, Elio has just released a new prototype of the tiny gasoline-powered vehicle...

Chevy's Cruze diesel is one of the more significant cars arriving this year. It's not just economical by Chevy's own standards, but at 46 mpg highway it comfortably takes the fight to the class-leading Volkswagen Jetta TDI too, With a 15.6 gallon gas tank, that 46 mpg should be enough to get you...
