Fuel Efficiency

Michelin has introduced a prototype airless tire that will soon be tested on a Chevrolet Bolt EV fleet in Michigan.

If the federal government revokes California's waiver allowing it the authority to regulate emissions, the state's agency is making clear it will find a way to keep the polluters out.

With electric pickup trucks from Ford, GM, and others—including newcomers like Rivian—looking likely to arrive in the next few years, the truck field could be on the verge of a clean, quiet, tailpipe-emissions-free shakeup. That said, you wouldn’t know this segment as being poised...

If more power, a 226-mile range, and a $39,405 base price—before considering the full $7,500 federal EV tax credit you can still get—collectively seems like the sweet spot for the Leaf, you probably have GM to thank. Nissan has admitted that it never planned to push the Leaf above a...

Given the daily churn of electric-car announcements, major manufacturing investments, and battery supply-chain news, it could be a little hard to understand one reality-check projection: that even in 2030, a solid majority of vehicles sold could still burn fossil fuel. Last week, LMC Automotive, a...

In just one model year, Kia has more than doubled the rated driving range for the Soul EV. The 2020 Kia Soul EV, which is expected to reach dealerships this spring, will go 243 miles on a charge—four more miles than the Kia Niro EV—according to the EPA, in ratings that were released...

It turns out there's more than one way for automakers to meet fuel-economy targets. One is to develop and sell more fuel-efficient cars and trucks. The other—as demonstrated over the years by quite a few automakers—is to pay fuel economy fines to the U.S. Treasury as a course of doing...

Last week the U.S. EPA released final fuel economy numbers for the 2020 Toyota Corolla lineup. They include a confirmation of what Toyota had claimed when it introduced the lineup last fall: that the Corolla Hybrid will carry an EPA combined rating of more than 50 mpg. The 2020 Toyota Corolla...

Ten years ago this week, in February 2009, Green Car Reports published its first story—one packed with insight regarding the Chevrolet Volt, which was then still nearly two years away. Despite all that could have happened to the Volt in GM’s bankruptcy, it arrived on time and was...

A look under the hood of Mazda’s future includes a patchwork of “what if” possibilities and a series of juggled timelines. Mazda is in a tough spot right now with regulators and in finding its place across many global markets. Part of the issue is that Mazda is considered an...

Former Porsche AG CEO Wendelin Wiedeking, who waged a failed takeover of the Volkswagen Group ten years ago, is reportedly one of the backers of a new venture that, at face value, is making claims that sound very much like those made of what was then the favored tech for VW and Audi: TDI diesel...

Mazda has revealed its 2019 Mazda 3 compact car, in new-generation form, at the 2018 LA Auto Show. It’s not surprising, given the brand’s go-it-alone strategy this decade, that the new ‘3’ appears to take a different path than key global compact-car rivals in nearly every...

Yesterday, when we brought you our 2019 Toyota RAV4 Hybrid first drive review, we missed one very important point. At 39 mpg, the RAV4 Hybrid is now the highest-mileage sport-utility vehicle (as the EPA lists them) without a charge port. All the more impressive is that it’s not a low...

As solar cells get more efficient, powerful panels can fit on smaller areas. For those looking to use renewable energy for transportation, that means solar panels can now move from home rooftops used to power car chargers to cars themselves. In Korea on Wednesday, Hyundai and Kia revealed some...

Less than a week after speaking out in favor of a national electric vehicle mandate, and in the shadow of Tesla reporting a profitable quarter, General Motors might be on the verge of announcing a radical change to its plans for future electric vehicles and plug-in hybrids in the U.S. The automaker...

It’s been less than five years since Volkswagen produced its limited run of just 250 XL1 plug-in diesel hybrid coupes, of which only 200 were sold to retail buyers. The Volkswagen XL1 has all the makings of an instant collectible, with its combination of low production volume, advanced...

The term “hail Mary” might be appropriate for what General Motors, led by chief executive officer Mary Barra, is attempting at this stage of the federal government’s dialog on fuel efficiency and electric vehicles. GM is launching an effort to propose a 50-state solution for...

Although Tesla may still sometimes be finding its way in terms of how to build cars themselves, it retains a distinct advantage over pretty much every other automaker in one respect: superb power management. Buried in the company’s third-quarter 2018 financial results—hailing a...

Readers who want to make their voices heard in objection to (or support of) the EPA proposal to freeze fuel economy standards have until tomorrow to get their comments in. The EPA proposed in early August to undo Obama-era rules requiring cars to reach increasingly stringent fuel-economy targets...

Drivers are not helpless in the face of government plans to roll back fuel economy standards. A joint August proposal from the EPA and NHTSA to freeze planned increases in fuel economy standards is out for public comments until Oct. 23. Public comments can make a difference. DON'T MISS: Trump...
