Mazda3 Skyactiv-CNG Concept

Last week,  Mazda CEO Masamichi Kogai said that the company had no plans for a production Wankel rotary anytime in the near future, though the company most identified with the engine that goes “hmmmm” will continue to do research on rotaries. Now, at the Tokyo Motor Show, Mazda is showing that its future powertrain plans include diesel, natural gas and hybrid drives.

Honda FCX Clarity

Remember this piece from the Honda Summer 2008 Hydrogen Collection? It was supposed to point the way to future of green fuel technology before the Tesla brought plug-in sex appeal down the ramp with their Roadster and, later on, the S, as well as the trend of compliance EVs from Chevrolet, Volkswagen and Kia.

But with sales of plug-in hybrids advancing far slower than originally expected regulators are taking another look at alternative ZEV powertrains.

Dirty-and-Clean-Air-Filter

The contrarian in me loves it when conventional wisdom is proven to be not so wise. For decades, even before the first oil crisis of the 1970s, motorists have been told that making sure that your air filter is clean is one of the ways that you can improve  your fuel economy. It’s intuitive to think that a clogged air filter will affect the way an engine “breathes”, how efficiently it can get gases in and out of the combustion chamber and how that might decrease fuel economy. That may have made sense decades ago, however it turns out that two different studies, one on gasoline engines and the other on diesels, performed by a team at the Oak Ridge National Laboratory, show that the fuel economy of modern, digitally controlled fuel injected engines isn’t significantly affected by the state of their air cleaners’ cleanliness. What made sense in the era or carburetors may no longer be applicable today. Apparently the engines’ ECUs working to keep emissions in spec are capable of leaning out the fuel mixture to account for a dirty air filter restricting airflow into the engine, resulting in insignificant drops in fuel economy. Though dirty air filters didn’t materially affect fuel economy in the modern cars, they did experience a decrease in acceleration performance so it’s still a good idea to replace a dirty air filter.

V6-diesel-426x350

Fiat is now the proud owner of VM Motori after acquiring the remaining 50 percent of the diesel engine maker from General Motors for $47.1 million.

The first half of VM Motori was purchased by Fiat in 2010, with GM exercising a put option to purchase the remaining half. VM Motori now supplies diesel engines for the forthcoming Jeep Grand Cherokee and Ram 1500 EcoDiesel – an engine originally developed for the European Cadillac CTS.

Chevrolet-Tavera-Neo-3-Engine

The Times of India and the Hindustan Times are reporting that a panel appointed by the Indian government to look into General Motors’ recall last summer of 114,000 Chevrolet Tavera multiple use vehicles says that the company violated testing regulations, according to a government official who has seen the report. The recall came after a surprise check by the Automotive Research Association of India, an industry group that works with India’s Ministry of Transportation, found that the Tavera’s production diesel engines were not consistent with those that GM had supplied for testing.

Chevrolet will not be the sole brand in GM’s stable to offer a diesel passenger car. According to reports, Buick is next up for a diesel engine. It’s not known which Buick would get an oil burner but the likely candidate is the Verano, which shares a platform with Chevy’s Cruze, which is now available with a four cylinder turbo diesel in the U.S. The Opel Astra, even more closely related to the Verano, already offers a 1.9 liter CTDI diesel in Europe.

Hackenberg talks to reporters from SAE Magazine and Fortune …

“It is good for the future of diesel in the USA that  a domestic producer also uses a diesel engine,” said Volkswagen’s R&D Chief Dr. Ulrich Hackenberg today.  “If the volume of diesel engines is increasing, then it makes sense to produce diesel engines in the U.S.A. That would be great for us and the customer,” Hackenberg said. Read More >

My TDI in Japan

The engine quit with a sudden un-dramatic snap, and the little Golf TDI began to slough off speed. Reflexively, I bumped the gearshift lever into neutral, flicked on my signal and began moving towards the left edge of the expressway. My exit was less than a mile away and, rather than stop alongside the highway, I used my momentum to coast up the off-ramp and over the small knoll that stood between the expressway and the toll plaza. I stopped there, on the back side of the hill where the road widened on the approach to the toll booths, to avoid blocking traffic and dug out my cell phone to call for a tow truck. I didn’t know it then, but it was the last time that I would ever sit behind the wheel of the little car, never mind the fact that it would follow me again around half of the globe. Read More >
