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.

Volkswagen poised to enter F1 with Red Bull

The Volkswagen Group could finally be preparing to enter Formula One, and enter it in a big way. That is, at least, if the latest reports prove accurate. And given the source, we're taking notice. The word around the paddock this weekend in Singapore has it that VW is entering into a partnership with Red Bull Racing that would see the German auto giant not only supply the team with engines, but buy the team altogether. The move would come as a welcome development for Red Bull, which took four consecutive world championships between 2010 and 2013, but has fallen off pace over the past couple of seasons due in large part to the under-performance of its Renault engines. The deal, which according to the report is currently being finalized, would see VW develop an all-new engine for Red Bull (and potentially for Toro Rosso and other customer teams), but the new power unit wouldn't be ready before 2018. In the interim, Red Bull would break off its current deal with Renault a year early and switch to another customer engine arrangement, with Ferrari currently rumored to be the favorite. The energy drink company that currently owns the team, in turn, would revert to a (prominent) sponsorship role - similar, it bears noting, to the role it plays with VW's World Rally Championship team. The termination of the relationship with Red Bull could spell the end of Renault's current F1 program, unless the French manufacturer carries through with plans to reacquire its stake in the Lotus team that was once its own. The VW deal would also ostensibly put to rest the mooted arrangement that would have seen Red Bull switch from Infiniti sponsorship and Renault engines to a similar deal with Aston Martin and Mercedes. What isn't clear at this moment is which brand Volkswagen would choose to promote with the new F1 program. Audi is speculated to be the favorite, which would likely spell the end of its Le Mans prototype endurance racing program – leaving that realm to Porsche after a solid decade and a half of dominance. The board in Stuttgart could, however, opt to hand the opportunity to one of its other brands, including Bugatti, Bentley, Lamborghini, Seat, Skoda, or the Volkswagen brand itself. The news comes from not only from the BBC, but from its analyst Eddie Jordan – a man who knows a thing or two about running an F1 team... and selling one. Jordan ran his eponymous grand prix team from 1991 through 2005.

VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.
