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.

The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.

Dealers, owners feel betrayed by VW scandal

Bob Rand bought his Volkswagen Passat last year for its clean emissions and high gas mileage. He liked the car so much he convinced his son and a friend to buy one, too. Now, as Volkswagen comes clean about rigging diesel emissions to pass US tests, Rand is desperately trying to sell the fully loaded model with white leather seats for $10,000 below what he paid. His sole bite has been from a man who offered $7,500 on speculation that he could resell it in Mexico. "Volkswagen was somebody that you could rely on for cutting-edge products and quality and all those things and now you find out that they're not above lying just flat out," said Rand, who plans to join a class-action lawsuit against VW. "That's probably about as bad a thing as a company can do is lie to your face when you're buying a $35,000 car." Rand's anger at the world's top-selling car company was echoed Wednesday by private dealers, auto wholesalers and owners across the US as fallout from the smog test trickery mounted. The US Environmental Protection Agency first disclosed Friday that stealth software makes VW's 2009-2015 model cars powered by 2.0-liter diesel engines run cleaner during emissions tests than in actual driving. On Wednesday, CEO Martin Winterkorn resigned and took responsibility for the "irregularities" found by US inspectors - a scandal that has wiped out billions in the company's market value and raised the possibility of criminal investigations and billions more in fines. The revelations left dealers sitting on hundreds of diesel cars they could not sell. Many also dealt with a flood of angry calls, emails and tweets from Volkswagen owners who felt betrayed because they believed they had bought a car that polluted less without sacrificing the good gas mileage and performance that comes with a diesel engine. "I think their feet should be held to the fire." - Joe DeCarolis "I think their feet should be held to the fire. I think apologies don't mean anything when something is so premeditated," said Joe DeCarolis, of Cary, NC, who owns a 2012 TDI Jetta Sport Wagon — a car he bought after careful comparison shopping for its clean emissions and good gas mileage. Dealers can't give customers good answers because Volkswagen hasn't said a whole lot, said AutoNation CEO Mike Jackson, the leader of the largest auto dealership chain in the US.
