If you put us in charge of Porsche Boxster development, we'd have demanded more power, less weight and improved fuel efficiency. We now know that the new 265-horsepower, 2.7-liter boxer six is capable of producing 10 more ponies than the outgoing model, and overall tonnage was slashed by 55 ...

When Audi announced the 2013 A8 with the 3.0T V6, it didn't mention fuel economy numbers but did tout the 333-horsepower engine's "great efficiency." According to the United States Environmental Protection Agency, the V6 efficiency exactly matches that of the more powerful 372-horsepower, ...

As predicted and expected, the Environmental Protection Agency today approved the first applications to make E15, a blend of gasoline with 15 percent ethanol in it. This means that E15 is now a "significant step" closer to production and sale in America. For decades, gasoline in the U.S. has had ...

Small, rear-wheel drive, manually shifted coupes can be exciting, no? Fun and zippy to drive, and because of their tighter dimensions and lower weight, they tend to be easy on the gas, right? Well, in the case of the Subaru BRZ and the Scion FR-S, maybe not as much as we'd have hoped. Sure, they ...

Remember that new 36-mpg 2012 BMW 3 Series we were so excited about, the 328i that got better fuel economy in EPA testing than even the old 335d diesel model? Well, those early estimates haven't held up. BMW has confirmed to Autoblog that the EPA has issued revised numbers for the eight-speed ...

Police forces didn't care much about fuel economy back in the early days of the Ford Crown Victoria, but these days, efficiency is front and center for cash-strapped municipalities. The cost of fuel keeps rising and cities continue to cut their budgets, so one or two miles per gallon might make ...

If there's one thing we've learned from the Barrett-Jackson hype machine, it's that if you want to sell an old car for ungodly sums of money, it helps to have a good yarn to tell about it. Which is why we're somewhat shocked to see this Superbird fail to attract enough interest from bidders at ...

Coming soon to select Ford dealers, at least those on the coasts, is the most efficient five-passenger car in America, the 2012 Ford Focus Electric, which the EPA has certified gets 105 miles per gallon equivalent, combined. This is better than what the Blue Oval was estimating publicly in ...

The Science Committee in the House of Representatives has a approved a bill that would prevent the Environmental Protection Agency from allowing the use of gasoline with a higher ethanol content without additional study. According to The Detroit News, the bill was sponsored by Rep. James ...

All automakers are under pressure to hit more stringent Corporate Average Fuel Economy (CAFE) regulations, figures set by the National Highway Traffic Safety Administration (NHTSA). In 1978, the CAFE standards were just 18 miles per gallon, but they have increased gradually each year. This ...
