ACEEE strips away VW's green car scores

The American Council for an Energy-Efficient Economy (ACEEE) is confirming that the Volkswagen diesel-emissions scandal has put a black mark on its green ratings. As a result, the group is pulling VW diesel vehicles off of its "Green Scores" list because it was recently revealed that VW diesels might be emitting as much as 40 times the nitrogen oxide (NOx) emissions during normal driving as the official test results show. The ACEEE added that other German makers of diesel vehicles' "Green Scores" are safe, for now. Diesels from VW and the company's Audi division didn't exacatly top the ACEEE's list of greenest vehicles for 2015. That honor went to electric vehicles like the Smart ForTwo ED, Chevrolet Spark EV and Fiat 500E. The Toyota Prius C hybrid snuck in at number 4, while the Nissan Leaf battery-electric took the fifth spot. That said, the VW diesels did perform pretty well, according to the group. "These scores are no longer reasonable estimations of the environmental impact of the Volkswagen diesels. Volkswagen's diesel cars have performed well on ACEEE's annual rankings since 2009, hovering just below our list of the top twelve "Greenest" vehicles with Green Scores in the high 40s," wrote Shruti Vaidyanathan, senior transportation researcher at the ACEEE. "However, a 40-fold increase in on-road NOx would mean that these vehicles did not deserve those high Green Scores." For those curious, the Ram 2500 pickup topped the ACEEE's "Meanest" vehicle of 2015, followed by the Chevrolet G2500 Express/GMC Savana. No diesels showed up on that list of environmentally-damaging vehicles. You can read the ACEEE's statement on VW below. Why we are suspending Volkswagen diesel Green Scores on greenercars.org by Shruti Vaidyanathan, Senior Transportation Researcher On September 18th, the Environmental Protection Agency (EPA) slapped the Volkswagen Group with a notice of violation (link is external) of the Clean Air Act for circumventing EPA emission standards for nitrogen oxides (NOx). Volkswagen has now acknowledged using so-called "defeat devices" on its diesel cars that turn on full emissions control technologies while in testing mode but allow the vehicles to emit nitrogen oxide levels up to 40 times the certified level during normal operation.

Tanner Foust and Scott Speed get VW internships

Tanner Foust and Scott Speed both already have quite impressive motorsport resumes. The former is a rallycross and drifting champ, and the latter counts two years in Formula One with Toro Rosso among his accomplishments. Still, it's never too late for a career change. In a humorous new ad for Volkswagen, the professional racers take on the duties of summer interns at a dealership. The commercial is timed with the kickoff of the 2015 Global Rallycross Championship season in Fort Lauderdale, FL, on May 30 and 31. Speed and Foust are both racing in Beetle GRCs for the Volkswagen Andretti Rallycross team. This year's Bug is even more potent than last year, though. It now packs a 2.0-liter turbocharged four-cylinder engine to produce 553 horsepower and 465 pound-feet of torque, versus the previous 1.6-liter turbo four with to 544 hp and 387 lb-ft. The racer can reportedly hit 60 miles per hour in just two seconds thanks in part to low gearing and all-wheel drive. One of the Andretti team Beetles might look a little different, too. Foust is sticking with his Rockstar Energy Drink sponsorship, but Speed gets an animalistic livery for Shark Week to celebrate the annual event from the Discovery Channel. Check out both of the cars in the gallery below or the ad in the video above. SCOTT SPEED TO RACE SHARK WEEK THEMED BEETLE GRC IN RED BULL GLOBAL RALLYCROSS SEASON OPENER Scott Speed and Tanner Foust will contest the Red Bull Global Rallycross Championship in Beetle GRCs, starting this weekend in Fort Lauderdale Herndon, VA — The Volkswagen Andretti Rallycross team begins its second full season of racing this weekend in Ft. Lauderdale. The team will again be battling with two Beetle GRC race cars, which debuted in the closing races of 2014. As Volkswagen enters its fourth consecutive year as a presenting sponsor of Discovery Channel's SHARK WEEK, Scott Speed will concurrently begin the Red Bull Global Rallycross season behind the wheel of the No. 41 SHARK WEEK Volkswagen Beetle GRC, wrapped for SHARK WEEK, which begins on July 5th. "My father raced with No. 41 in karts when I was younger so it's pretty special to me," said Speed. "I have only had the option to choose the No. 41 twice in my career and was able to win championships each time. Hopefully it continues to bring me luck in 2015!" New this year, the team has chosen to change the engine specification from the Beetle GRC race cars that ran in 2014.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.
