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.

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.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
