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.

The techie choice | 2017 Toyota Prius Prime Quick Spin

The Prius nameplate has been inexorably tied to the green car scene for a long time now. When Toyota unleashed the Prius Prime upon the world, we said it was the best Prius yet. But this is no longer a world where Toyota's hybrids are automatically crowned king. Our recent time with the Hyundai Ioniq trio was a stark reminder that the economical, eco-conscious competition is getting stiffer. We put some miles on a Prius Prime to see how our recent Ioniq Plug-In Hybrid test colors our view of Toyota's prime contender. Our first impression: the Prius design is very clean and inorganic. As sterile as it feels, the design appears to have a lot of actual thought behind it. Our Advanced trim tester is spiritually in touch with the mobile gadget culture, with a huge touchscreen, digitization of seemingly everything, and white and black glossy plastic aesthetic. It's a tech-heavy design that will likely seem familiar to those of us who have been interfacing with Apple designs for the past 10 or so years. The Ioniq Plug-In Hybrid, on the other hand, remains truer to the look and feel most drivers expect from their commuters. It's less about user interface, modes, and drive data, and more about just getting behind the wheel and driving. The Ioniq Plug-In Hybrid hardly even distinguishes itself from its plugless counterparts, opting to go green under cover rather than the in-your-face futurism the Prius projects. It retains the traditional instrument cluster in front of the driver, too, which the Prius Prime lacks. In the Toyota, you'll have to look around the car for the right display with the information you're looking for – there's the huge central touchscreen with all its menus, as well as smaller displays above it on the dash – or you can find your speed on the HUD. The Prius is composed in its handling, but doesn't provide much of the sensory feedback that makes one feel connected to the chassis. The steering feels super artificial, but the car stays fairly flat in the corners without providing too much feedback through the seat of your pants. Hyundai's offering, though, proved to be a surprisingly willing dance partner in the corners. While feeling equally as capable as the Prius, the Ioniq's sense of connection through steering and suspension made the act of stitching one turn after another together enough to get our blood pumping. Sport mode makes the Prius Prime slightly livelier, though.

Jay Leno gets behind the curtain on the design of the Toyota FT-1 concept

Hinting at the future of Toyota performance vehicles, the FT-1 concept was one of the stars of the Detroit Auto Show this year. It even nabbed fourth place in our Editors' Choice list. While he's a few months behind the car's official reveal, Jay Leno managed to get the only existing concept of the sports coupe wheeled into his garage to take a closer look, and he's pretty impressed.
Leno speaks with Alex Shen and William Chergosky, the exterior and interior chief designers of the FT-1 respectively, to get a better idea of the inspirations behind the concept. Jay heaps high praise on it for mixing Italian and Japanese design and says he likes the look even more than the Lexus LFA. The coupe isn't a product of either country, though. It was penned at Toyota's CALTY Design Research center in Newport Beach, CA.
The designers go into the entire history of the FT-1, and Shen even admits that Toyota design lacks an emotional factor at the moment. It's a fascinating interview behind some of the little touches you might miss at first glance. Unfortunately, the model doesn't have the green light for production yet and may never get made. In any case, scroll down to watch Leno swoon over the coupe.
