Elon Musk says VW scandal proves limits of fossil fuel cars

Tesla Motors chief Elon Musk didn't appear to mince words when commenting on Volkswagen's diesel-emissions scandal when making comments at the Federal Ministry for Economic Affairs and Energy conference in Berlin this week, according to Bloomberg News. Musk called the news of scandal "obviously bad." He also used the opportunity to note that he thought the German automotive industry may be lacking when it came to getting its powertrains to cut emissions. Pretty tough talk in Berlin. Musk did note that, when it came to clean electricity generation, Germany was ahead of many countries. But he also used the occasion to note that global industries could do a better job addressing "the chemical constituency" of the world's air and oceans. Musk also spoke to the Belgian press about the VW scandal this week. Asked if people might lose their faith in green technology, Musk said that what the scandal shows is that "we've reached the limit of what's possible with diesel and gasoline. And so, the time, I think, has come to move to a new generation of technology." You can see his comments in the video above, starting at 1:12. Musk made these comments as the automotive industry reacts to news that Volkswagen tried to game the system by manipulating its diesel-powered vehicles to meet worldwide emissions regulations. VW has set aside $7.3 billion to address the issue, and has estimated that at least 11 million vehicles may have been programmed to cheat emissions mandates. As a result of the scandal, VW CEO Martin Winterkorn has stepped down and Porsche chief executive officer Matthias Muller has taken over. For those keeping track, VW sold almost 51,000 diesel vehicles in the US through the first eight months of the year. That is about eight percent less than a year earlier but is probably about three times the number of Tesla Model S electric vehicles Musk sold in the US (we say probably because Tesla discloses neither monthly nor country-specific sales). So, while this may not be a case of diesel envy, Musk did have a pretty wide-open shot to tweak VW and its reliance on diesel technology.

Bosch fuel pumps spark recall of 2015 Golf, GTI and Audi A3

A few weeks ago, BMW and Nissan both issued recalls for some of their vehicles to replace Bosch-supplied fuel pumps. The pumps had nickel plating that could flake off and cause a failure. Volkswagen Group is the latest automaker to be affected by the problem and has a campaign for the 2015 Audi A3, VW Golf and GTI. In total, 6,204 units of these models are in need of repair. The problem with the VW Group vehicles is identical to the previous recalls. It's possible for the pump's nickel plating to come off and cause increased friction. Eventually, this can result in the component's failure. According to documents from the National Highway Traffic Safety Administration (as a PDF, here), there are no reports of accidents or injuries from this issue in the VW Group models. Bosch spokesperson Linda Beckmeyer tells Autoblog that these vehicles don't all necessary share an identical fuel pump, but the parts all use the same plating process. The problem also prompted repairs of the 2014 Ford Escape several months ago, she indicated. When asked if the issue could prompt more campaigns, Beckmeyer said that she "can't speak to that" because automakers decide on the recalls. Owners should receive notice of the problem soon, but according to the NHTSA documentation, there currently aren't enough pumps to fix all of these vehicles. "Bosch is working closely with automakers regarding replacement parts," Beckmeyer said. When available, dealers will replace the components free of charge for affected customers.

SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2015 Volkswagen Golf, GTI, and Audi A3 vehicles. Improper nickel plating of components within the fuel pump may result in the fuel pump failing. CONSEQUENCE: If the fuel pump fails, the vehicle will not start, or if the engine is running, it will stop and the vehicle will stall, increasing the risk of a crash. REMEDY: Volkswagen will notify owners, and dealers will inspect the vehicles and replace any affected fuel pumps, free of charge.

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.
