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.

1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.

Opel's own ad shows Ampera-e beating Opels in drag race

The Opel Ampera-e isn't expected to set any world records on a quarter-mile drag strip. But when it comes to crossing a major boulevard, though, the European version of the Chevrolet Bolt electric vehicle will more than hold its own, potentially scaring inattentive pedestrians everywhere. According to a 35-second video posted by General Motors' Opel division, at least. Opel set up the Ampera-e against four other small-and-sporty vehicles, including racing versions of the Opel Adam and Opel Astra as well as stock versions of the Opel Insignia and Corsa (what, you expected a Corvette to be in there?). With the EV's off-the-line torque as a selling point, Opel showed the Ampera-e beating the other vehicles in a 30-meter (100-foot) drag race. Of course, the video also shows the EV getting passed by some of the others soon after, but the point was made. Opel doubled down by adding the tagline "Fun to Drive" at the end of the video. While Opel hasn't revealed the single-charge range of the Ampera-e, it should be roughly the same as the Chevrolet Bolt, which will be about 200 miles. In addition, the Ampera-e, like the Bolt in the US, will get 200 horsepower from its electric motor, and will be able to go from 0 to 60 miles per hour in less than seven seconds. The Ampera-e will debut at the 2016 Paris Motor Show later this month. General Motors said in February that Europe would get the Ampera-e by next year. Opel had previously used the Ampera name with the Euro version of the Chevrolet Volt extended-range plug-in.
