Ex-Fiat exec: VW diesel scandal will hurt plug-in hybrids

It doesn't sound right at first blush, but former Fiat executive and noted diesel-powertrain expert Rinaldo Rinolfi thinks that plug-in hybrid sales may be more impacted by the VW diesel-emissions scandal than diesel sales. Rinolfi, who worked for Fiat for 40 years, told Automotive News Europe, said that the Euro 6 emissions rules that went into effect in 2015 have already increased diesel-engine production costs enough to raise prices and ultimately flatten demand. By the end of the decade, diesel-vehicle sales will settle in at a 40-percent market share of new European vehicles, and that was going to happen with or without the scandal. "Every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions." - Rinaldo Rinolfi Makers of plug-in hybrids have more to lose, though, because every PHEV maker has figured out a way to keep emissions figures artificially low, Rinolfi said. Under New European Driving Cycle (NEDC) standards, PHEVs can be tested part of the time with the electric motor in action, meaning emissions get driven down to 30 percent to 40 percent less than real-world figures. With the VW scandal pushing regulators to use real-world figures, those PHEV emissions numbers are expected to rise substantially. To a lesser extent, hybrid emissions figures are also tested as artificially low. "Over the years, even without defeat devices, every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions the customer experiences," Rinolfi said in the Automotive News Europe interview. Rinolfi is a little sunnier about compressed natural gas (CNG) vehicles, estimating that CNG emissions are as much as 25 percent lower compared to conventional vehicles. As for battery-electrics, he's not so optimistic, estimating that there needs to be at least a tenfold improvement in energy efficiency for EVs to be truly competitive with conventional vehicles. "I've been waiting for a true breakthrough for the past 25 years, but I've not seen it yet," Rinolfi said about EVs in the Automotive News Europe interview.

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:

VW to unveil diesel-electric Twin-Up! in Tokyo

We've received multiple reports that Volkswagen will be bringing a diesel-electric concept to the 2013 Tokyo Motor Show, set to take place later this month. The car, called the Twin-Up!, is based on the Up! city car, with some sources claiming this is a thinly veiled concept that will eventually enter production.
According to Automotive News Europe, the Twin-Up! will reportedly return 214 miles per gallon on the US cycle by combining an 800-cc, two-cylinder diesel and an electric motor. It will also boast plug-in capabilities, and will be able to cover 30 miles on electric power alone.
Autocar has a more complete picture of the Twin-Up!'s powertrain, though, claiming it's a modified version of the hybrid system found in the Volkswagen XL1. The Twin-Up! will get a more potent, 47-horsepower electric motor to the XL1's 27-hp unit, but will retain that car's 47-hp turbodiesel. The battery pack will also grow, from 5.5 kilowatt hours to 8.6 kWh. Both of these increases are necessary due to the increased weight of the Twin-Up! - it's some 900 pounds heavier than an XL1.
