Audi RS3 and Volkswagen Golf R face off in Evo test

Typically when an automotive publication pits two rivals against each other, they come from different companies. After all, why would one automaker – even one parent company – develop two distinct models to compete against each other? Well, the Volkswagen Group isn't like most. It pits Porsches against Lamborghinis, Audis against Bentleys, Seats against Skodas... all under the same roof. In the high-powered hot hatch market, it offers both the VW Golf R and the Audi RS3. The question is, which is the better drive? Evo put them both on track for a quick bout of sibling rivalry to find out. On paper it would seem like an unfair fight. Sure, both are based on the same platform and channel their power to the tarmac through all four wheels. But the Audi's five-cylinder engine packs considerably more muscle than the Golf's four: 362 horsepower and 343 pound-feet of torque trump 296 hp and 280 lb-ft. There's just no way around that – at least until the Golf R 400 comes along. The Audi, as you might have guessed, also costs substantially more than the Volkswagen. But that's not Evo's concern here. This is a cost-no-object, bare-knuckle throw-down. Watch the ten-minute video above to find out if the cheaper, less powerful Golf R can keep pace with its more upscale and brawnier brother.

VW air rule violation allegations 'stunning,' $18B fine unlikely

The big automotive news today was the US federal allegations that VW quietly and illegally installed software on approximately 482,000 diesel vehicles sold in the United States so that they would not return substandard results on government emissions tests. To say the least, this is potentially a very big deal. You can read the details of the government's allegations here. The problem seems to be with the NOx trap. Sam Abuelsamid, a former AutoblogGreen editor who is now a senior research analyst at Navigant Research's Transportation Efficiencies program, told me that there were some hints that VW's diesel emissions strategy had issues a while back. The vehicles affected by today's announcement are all equipped with the 2-liter, 4-cylinder TDI, he said. They all have the lean NOx (nitrogen oxides) trap, whereas all other current modern diesels use urea to treat NOx emissions. "When VW launched those vehicles, I went to the TDI launch program in Santa Monica and asked them if they were going to put the diesel engine into the Tiguan because that would be an ideal application," he said. "They said no, because it would be too heavy. Turns out, the NOx trap was enough to meet the emissions standards in the smaller cars, but not the Tiguan. That seems to be where the problem is, in the NOx trap. All the other big VW and Audi diesels, they use urea, just like BMW and Mercedes do." Abuelsamid added that, in California, to do an emissions test, testers don't stick a probe up the exhaust, as you would suspect. Instead, they just do a visual test to make sure nothing was tampered with and then plug a scanner into the OBD-II port to read the codes. The news today basically says that the cars were programmed to send out false codes, giving readings that testers are looking for instead of what's actually going on. "That's the background, as far as I know at this point," he said. This could be "a black eye on the auto industry." - John O'Dell Speaking at the AltCar Expo in Santa Monica just hours after the news first broke this morning, Edmunds.com's John O'Dell said the Fed's allegations were "stunning." The idea that VW might have gamed the system, he said, "underscores how important EPA clean air numbers are, that a company would allegedly stoop to this to try and meet them. Obviously, people are paying attention to that sort of thing.

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.
