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.

VW Jetta TDI dyno shows HP loss trying to recreate cheat mode

Volkswagen is working on a fix for diesel-engined vehicles that are out of compliance with emissions regulations in the US and other countries. We're told that engineers will be presenting a solution internally sometime this month, but that doesn't mean we'll actually see it in the wild this month. One big question we have about the coming fix is, will it affect the car's performance? That question relates to another we have about the engine as it is: How much performance would the 2.0-liter diesel lose right now if it were turned down to pass US emissions? The Fast Lane Car tried to sketch some answers by going to a shop in Denver, Colorado to run a 2011 Jetta TDI with a six-speed DSG transmission on an all-wheel-drive dyno. The thinking was that if you ran all four wheels the car would think it was on the road, whereas if you ran only two the car might think it's being tested. We'll get straight to the numbers: the stock sedan is quoted at 140 horsepower and 236 pound-feet of torque. When run with all four wheels turning it produced an uncorrected 114 hp and 214 lb-ft at the wheels. When run with just two wheels in motion the Jetta got 113 hp and 188 lb-ft at the wheels. Reading the graph, we're told that power differences between the two runs were as much as 15 hp and 32 lb-ft. You'll need to take some salt with these numbers, though, because the dyno and test protocol in the video are nothing like those used by the EPA. The shop attempts to trick the Jetta into 'emissions testing mode' by using the front wheels only for the two-wheel-drive run, but we have a feeling the software code at issue is far more sophisticated than that, since the ICCT, UVA, the EPA, and CARB investigated the situation for more than a year and couldn't figure out. Also, the technician adjusts for being a mile above sea level with a correction factor of 1.2 applied to horsepower and torque, which inflates the disparity in the final power differences over the two runs.

Last VW bus ever made arrives at final destination

A Brazilian politician tried to save it, unsuccessfully, so the final Last Edition Volkswagen Type 2 Kombi was produced on December 20, 2013 and now resides in a vintage museum at Volkswagen's Commercial Vehicles HQ in Hanover, Germany.
The Volkswagen Microbus was built for 56 years, starting in September 1957. Brazil was the last country still assembling it, but new safety regulations in the country requiring airbags and ABS on all cars spelled the end. When that politician introduced a bill that would pardon only the 'Bus from a death sentence, it couldn't garner the required number of votes for passage. The South American country takes the Kombi production title, though, with 1.5 million of the 3.5 million total made in the home of Copacabana beach and the girl from Ipanema.
The VW Bus is dead. Now perhaps we can turn our attentions to the still-not-totally-settled matter of the Bulli...
