Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

Will VW's rumored 186-mile EV battery be enough?

Just as there continues to be a horsepower war in the realm of performance cars, there's an ongoing battle over driving range among electric vehicles. Both the Tesla Model 3 and Chevrolet Bolt are promising around 200 miles for a relatively affordable price in or around 2017. Plus, Nissan is reportedly nearing a 250-mile Leaf for about the same time and Ford might be joining the game, too. Volkswagen might be the latest potential challenger with some extra distance possible from its future EVs. According to Hybrid Cars, Volkswagen Chairman Martin Winterkorn tells Bild in Germany that the company is developing a new generation of battery tech with major gains, and it could reportedly provide a range of around 186 miles. That's more than double the current 83-mile EPA certified range for the e-Golf but falls short of the projections from competitors. Winterkorn didn't indicate exactly when this innovation would be ready for production, though. Especially in recent months, the German automaker is making serious moves towards big advancements in battery tech, and the company's platforms are largely already prepped to become EVs. The entire VW Group is reportedly considering moving to a single, unified lithium-ion cell design, and that switch could cut component costs by as much as 66 percent. In late 2014, the German automotive giant also bought five percent of the US-based startup QuantumScape. That business has claimed a staggering 430-mile range from its fireproof, solid-state lithium batteries, but the proof will need to be seen on the road – and in whatever the competition is able to accomplish whenever a car is finally available.

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.
