Gas Mileage

We've spent some time behind the wheel of the 2013 Mercedes-Benz SL 63 AMG and brought you our thoughts. Hint: it's luxurious, and it's fast. Read the review for the details. Ever wondered what the backstory to a one-off version of an already incredibly rare hypercar might be? Find out with this...

Lexus is rumored to be working on a car that's twice the LFA: twice the price, twice the power/performance, and twice as exclusive. But does that make any sense? Lotus went a little off-kilter yesterday, finally folding under the strain of what it calls widespread mis-reporting of the company's...

The Acura NSX isn't even real yet--it's just a concept made of hopes and dreams--but already the Roadster version is getting some mileage on the set of the Avengers. Travis Pastrana may have set aside his more extreme forms of work, but he's still ripping it up on four wheels, including a first...

We take an inside look at Porsche's near-term future in a roundtable discussion with some of the company's top brass, including CEO Matthias Mueller. Can you say plug-in hybrids, four-cylinders, and a new supercar? MINI might name the production version of the Paceman concept the Countryman Coupe...

With BMW's new four-cylinder turbocharged engine progressing steadily through the lineup, the X3's adoption of the small but punchy powerplant is far from unexpected. Nonetheless, it's a welcome addition, as we've come to love it in its other implementations. The 2013 X3 xDrive28i uses the same...

Today we have some unfortunate news: the first of the new F10-generation BMW M5s has been crashed in the Netherlands. It's not that bad a crash, but it's a sign of things to come, we expect. Transitioning from bad to interesting is Chris Bangle's new book, and the design contest built around it...

Today we all continue our preparations for the Detroit Auto Show, with perhaps the most impressive detail yet revealed being the 2013 Dodge Dart's claim of 40 mpg combined. That's a significant number for a non-hybrid, and not just for the Fiat-Chrysler merger. In non-show news, we just got back...

Yesterday we learned that McLaren solved a software glitch that had plagued several of its MP4-12C cars delivered to customers overseas. Today we have news that McLaren’s first road-going car since the legendary F1 won’t attract a gas guzzler tax when it hits the U.S. market. Despite...

Perhaps the biggest indication yet that Jaguar may finally be readying its ultra-frugal XF 2.2 Diesel for sale in the U.S. has come this week, with the British luxury brand announcing that one of the oil-burning sedans has embarked on a cross country tour. This white, British-registered and...

The upcoming Maserati SUV may not be named Kubang after all--a new report gives the nod to the much more melodious name "Cinqueporte." Buick is working on a Verano Hybrid, due by 2015, but before that, the WRC-inspired Prodrive-developed MINI Countryman should hit the streets. We also have BMW...

Stop-start technology is an easy way of improving a car's fuel economy by a few MPG and lowering emissions - especially if you regularly commute in heavy traffic. However, its use is contentious for many carmakers as the U.S. EPA official fuel economy figures are completely unaffected, even if...

Volvo is abandoning its traditional five and six cylinder engines in favor of more advanced and fuel-efficient three and four cylinder power plants.

Improving fuel economy and reducing noise can occasionally be mutually compatible - the smooth aerodynamics of a 2011 Toyota Prius making it a refined highway cruiser, for example. However, GM is trialling a technology in the Chevrolet Equinox that makes quietness an outright necessity for...

While most automakers are happy with the new standards, some aren’t due to an exemption for full-size trucks and some SUV models.

Ford isn’t going to let its rivals forget about the prowess of its new 2011 Mustang when it comes to fuel efficiency, which in V-6 guise is currently the only production vehicle on the planet with more than 300 horsepower and 30+ mpg fuel economy. Earlier this year the 305 horsepower 2011 Ford...
