These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Stellantis recalls heavy duty diesel Rams to fix fuel pumps

DETROIT — Stellantis is recalling more than 240,000 diesel heavy-duty trucks, mainly in North America, to fix fuel pumps that can fail and cause engine stalls. The recall covers certain 2019 and 2020 heavy-duty pickups and chassis cab trucks equipped with 6.7-liter Cummins diesel engines. The recall comes about a month after the National Highway Traffic Safety Administration opened an investigation into the pump failures. But Stellantis says the company started its recall determination process before the probe was announced. The safety agency said that in November of 2019, Fiat Chrysler (now Stellantis), maker of the trucks, issued a warranty bulletin to dealers telling them to collect fuel pumps on the trucks. Stellantis says some of the pumps can wear and contaminate their mechanisms with metal shavings, causing engines to stall or fail to start. Dealers will replace the pumps at no cost to owners, who will be notified by letters starting next month. Federal safety investigators opened the probe after getting 22 complaints and two field reports of engines stalling. There were no reports of crashes or injuries.

Ram 1500 TRX spied with remote-reservoir shocks and supercharger whine

The highly anticipated Ram 1500 TRX, Ram's Ford F-150 Raptor rival, has been spied again. And the big news is all in the suspension. Compared with the last prototype we saw, this truck sits much higher, and it now has fender flares to cover the wider track. It looks like some of the extra width may be from slightly bigger tires and higher offset wheels. But those might not be the only factors. Looking closely, the rear wheels have eight lug nuts versus six on the front. The previous prototype had six lugs on the rear. So this version may have a beefier rear axle, maybe from the Ram 2500. That axle may be a bit wider. The suspension itself is clearly farther along, too. Up front, there are some burly looking lower control arms. But in the back, any suspension reinforcements are long gone, and the axle seems to be supported by equally beefy trailing arms. Most exciting are what appear to be fancy remote reservoir off-road shocks tucked in the rear wheel arches. They're covered by little black sacks to hide them. The Rebel TRX concept from a few years ago featured internal-bypass shocks, and the Ford F-150 Raptor features the same kind of shocks. That Ram TRX concept also had 13 inches of suspension travel at each corner. Besides the updated suspension, we're pleased to report that the TRX is still rocking Hellcat power. Our spy photographer tells us that there's very audible supercharger whine. He also caught the truck on video, and it sounds gravelly and angry. We're very much looking forward to the truck's launch, which should be sometime before 2022.
