New Toyota semiconductors could increase hybrid fuel efficiency by 10%

Toyota may have an ace up its sleeve in the fuel economy wars, as it's developed a new type of semiconductor that will allegedly help the company's hybrids net a ten-percent improvement in fuel economy.
The tech is still in development, although Toyota is already reporting five-percent gains during testing, six years before it plans to implement the new semiconductor in production vehicles, meaning the ten-percent improvement doesn't seem like an untenable goal. That is, until you hear from Kimimori Hamada, the project general manager of Toyota's electronics division.
"We are aiming for great improvement in fuel economy and miniaturization," Hamada told Automotive News. "This is a very challenging target."

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.

Lexus takes aim at electric vehicles, again

Lexus is once again taking aim at plug-in vehicles by emphasizing the perceived challenges of recharging batteries, rather than simply filling up with gas or hydrogen. Only this time, Toyota's luxury division appears to be zigging while everyone else is zagging. Of course, the nameplate can use all the help it can get when it comes to hybrid sales. First highlighted by Green Car Reports, Lexus has added a banner to the website of its hybrid vehicles that says "Always Charged. Always Ready." That's a not-so-veiled shot at plug-in vehicles, a sector where Toyota has minimal exposure. Lexus also notes of its hybrid vehicles that there's "nothing to plug in." Of course, there may be sour grapes at play. Through September, sales of its five hybrid models in the US dropped 17 percent from a year earlier to about 21,500 units, and September was particularly tough as hybrid sales plunged 34 percent to almost 1,800 units. Even so, the third quarter likely represented a record when it came to plug-in vehicle sales. We say "likely" because Tesla doesn't break out its US sales, and not all automakers disclose sales of their plug-ins. We calculate that sales for the quarter were at about 36,000 vehicles, up 38 percent from a year earlier. For now, Lexus doesn't sell a fuel-cell model, though it may sell a fuel-cell version of the Lexus LS full-size sedan. Toyota, of course, offers the Mirai, which has moved about 710 units this year. Lexus has gone down this proverbial road before. In 2014, the brand unveiled a similar campaign that highlighted how long it took to recharge EVs, and was ultimately taken to task by electric-vehicle advocates Plug-In America. Lexus apologized for offending anyone and said it'd review content related to hybrid advertising. Doesn't seem like an apology is in order this time out, but that doesn't mean that it's a good strategy.
