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.

Toyota GR GT3 Concept: a long, lean racer with road aspirations

Toyota and Lexus trundled into the 2022 Tokyo Auto Salon with a bundle of modded gear. There are two especially racy bits — one, the GRMN Yaris we've already covered, and this, the Gazoo Racing GT3 Concept that is philosophically, if not aesthetically, related to the Yaris. Toyota believes it can provide more enjoyment for customers by commercializing race cars than by making customer cars racy. So instead of turning one of its road cars into a GT3-class competitor (Toyota does sell a Supra GT4), the GT3 Concept could be a customer potential race car that, as required by GT3 homologation rules, would become a road car.   Toyota Gazoo Racing President Koji Sato said the competition division will make a prototype GR GT3 at some point this year. That doesn't mean the exercise will go beyond this one-off, but Gazoo did also say, "TGR intends to use feedback and technologies refined through participation in various motorsports activities to develop both GT3 and mass-production cars and further promote making ever-better motorsports-bred cars," so its seems we will feel the effects of this somewhere. Based on the form factor of long, low hood and truncated, sloping rear, we could draw a line from the GR GT3 Concept to the Lexus Electrified Sport concept the luxury arm showed in December. Inspired by the LFA, that road car concept was claimed to hit 60 mph in the low 2-second range and be able to run about 435 miles on a charge. But we think it makes a lot more sense to draw a line from the GR GT3 Concept to Mazda's RX Vision GT3 concept from March 2020. We're not accusing GR of copying, but Toyota and Mazda are tight, and these two concepts could be confused for different skins on the same chassis in a video game. We'd be happy to see both make it to GT3 competition as it means there'd be street-legal versions, and frankly, this is probably a better path from circuit to street than the LMDh endurance racing hypercar that Gazoo Racing has toyed with turning into a street-going customer option. Elsewhere on the carmaker's Tokyo Auto Show stand, there was a racy on-road concept from Toyota and two off-road focused concepts from Lexus. The Toyota bZ4X GR Sport Concept turns the battery-electric crossover into a Friday L.A. nightclub hopper with a matte black exterior on big wheels in low-profile tires, and sport seats inside.

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.
