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.

2015 VW e-Golf coming to ZEV states for $35,445* this November

Is $6,465 too much to get someone thinking about buying a Nissan Leaf to opt for the Volkswagen e-Golf instead? That's the price difference between the current EV sales champion, which now starts at $28,980, and the just-announced price for the e-Golf, which will sell for $35,445 in the US when it arrives in about ten states (basically, the ZEV states that follow California's lead in zero-emission vehicle rules) this November and will qualify for the federal tax credit of up to $7,500. VW says that the extra money will get you "the most versatile electric vehicle in its class." There is only one trim line, the SEL Premium, which will be the first VW in the US with all-LED headlights. The car's powertrain numbers pretty much match the Nissan Leaf, though. The e-Golf has a 24.2-kWh lithium-ion battery (the Leaf has a 24-kWh pack) and a 115-hp, 199-pound foot electric motor (107 hp,187 lb-ft in the Leaf). The e-Golf's official EPA numbers are not yet available, but VW says it will have an "average range between 70 and 90 miles." The Leaf has an official EPA range of 84 miles. The e-Golf has a better onboard charger – 7.2 kW vs. 3.6 or 6.6, depending on your Leaf's options – and has SAE Combo fast charging capability as standard. VW is also working with 3Degrees to offset all of the emissions "created from production, distribution and charging of the e-Golf for up to approximately 36,000 miles of driving." VW also announced prices for its lightly facelifted 2015 Jetta today. The base model, the 2.0-liter S with a manual transmission, starts at $17,325 while the top-of-the-line model, the Hybrid SEL Premium, will set you back at least $31,670. The lowest-cost TDI is the S manual, which starts at $21,640 and features VW's new 2.0-liter diesel four. A new limited-edition 1.8 Sport model with a firmer suspension, tinted taillamps and rear spoiler starts at $20,895. All VW prices listed exclude VW's *$820 destination charge and you can find all the details on trim lines in the press releases below.

Bentley considering diesel engine for new SUV

Turns out, in case you didn't know, the rich are just like regular people. They too are concerned about the environment, even when tooling around town in their super-luxurious Bentleys. So the automaker is weighing the idea of offering a diesel engine in its SUV offering, which could help satisfy customers' demands for more fuel-efficient engines.
Chairman and CEO Wolfgang Schreiber told Autoblog in a roundtable interview at the Geneva Auto Show that the automaker is researching whether or not a diesel engine makes sense for the brand. Bentley, owned by the Volkswagen Group, could in theory use a diesel engine from anywhere in the Volkswagen Group family. We at Autoblog have hopes they'll revive the V10 TDI used in the VW Touareg until 2010, but ever-stricter emissions laws would likely make that problematic.
But rich people aren't so much like us that they'll be worried about petty things like pricing. Schreiber admitted the diesel engine could be a $15,000 option, which he said customers would probably find "acceptable." Given that the cheapest Bentley today starts at $177,000, typical customers probably won't be diddling around worrying about an extra 15 grand.
