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. Go to YouTube and read the lengthy comments on the video left by Andrew Price for a more thorough dissection of what could explain TFL's disparities. You can watch the video above, and feel free to try and dissect the results yourselves in the comments below. Related Video:

Winterkorn remains CEO of Volkswagen's majority shareholder

Martin Winterkorn may have stepped down as the chief executive of Volkswagen in the wake of the diesel emissions scandal, but he's not out from under the company's large umbrella just yet. In fact, according to a report from Reuters, he still holds four top-level positions not only within the industrial giant's bureaucracy, but at the top of it. And one of those is as CEO of the company's largest shareholder. That holding company is Porsche SE, the investment arm of the Piech and Porsche families (Ferdinand Porsche's descendants) which holds over 50 percent of VW's shares. In 2008, Porsche SE acquired majority interest in the Volkswagen Group which in turn acquired Porsche the automaker – and placed VW's Winterkorn at the head of the executive board of the holding company. Though Winterkorn has resigned from his position as chairman of VW's management board, he has apparently yet to step down from running Porsche SE. That's not the only job that Winterkorn still retains in VW's senior management. He also continues to serve as chairman of Audi, as well as truck manufacturer Scania, and the new Truck & Bus GmbH into which Scania has been grouped together with Man. It remains unclear if or when Winterkorn might resign from those positions as well, or how his tenure in those posts might affect the company's effort to start over in the aftermath of the scandal in which it is currently embroiled. Also unclear, Reuters reports, is how much, exactly, Winterkorn will receive in compensation after having stepped down from his chair at the head of the VW executive board. His pension is reported at over $30 million, but he could be awarded a large severance package as well amounting to as much as two years' worth of his annual compensation, which amounted to around $18 million last year. Whether he receives the severance pay or not is expected to depend on whether his resignation is considered by the supervisory board to have been the result of his own missteps or independent of the situation that resulted in his resignation. One way or another, he's not likely to go poor anytime soon.

Recharge Wrap-up: VW Golf TDI wins green car award, DC buses might go electric

The 2015 Volkswagen Golf TDI has won the award for 2014 Northwest Green Car or the Year. The distinction comes from the Northwest Automotive Press Association during its Drive Revolution event in Portland. Co-chairman of the event, Jeff Zurschmeide, says, "Volkswagen has led the diesel passenger car market for years, and the Golf TDI proves that they're likely to stay on top for a while." The 2015 Golf TDI has 10 more horsepower than the outgoing model, while improving fuel economy thanks to a new engine. It also has a base price $3,000 lower than the 2014 Golf TDI.

The laser lights use half the energy of their LED counterparts, according to BMW, which is important when one is trying to get every last bit of range out of the car's battery. The laser high beams can also reach about twice as far as LED lighting. Because of their brightness, they won't be available on cars sold in the US. In laser-equipped i8s, the laser high beams will not work below 60 kilometers per hour, nor when other lights are detected in front of the vehicle. Head to Automotive News Europe to read more. Renault has delivered a fleet of 30 Kangoo ZEs to Uruguay's government-owned power company, UTE. The electric fleet will allow the company to reduce its CO2 emissions by 36 metric tons, says Renault. 84 percent of Uruguay's electricity comes from renewable sources, with a goal of 90 percent on the horizon. Uruguay aims to get a third of its electricity from wind farms by 2016, meaning these Kangoo ZEs will be powered in no small part by renewable energy. For Renault, "This order is a further sign of the interest in the region for electric vehicles," according to Denis Barbier, Renault's senior vice president, citing previous deliveries in Brazil, Mexico, Argentina and Colombia.

Some of the diesel buses, which were first put to work in 2003, are nearing the end of their life cycle, and DC sees an opportunity to make the switch to something a little greener. "Electric has not been a viable option in previous procurements, but now it is," says Will Handsfield, Georgetown Business Improvement District's transportation director. Handsfield is concerned about air quality, and says he also appreciates the long-term stability of electric rates compared to diesel.
