Toyota Mirai officially first hydrogen-powered pace car

In addition to the chance to see bumper-to-bumper racing in a unique atmosphere, the roar of V8 engines is one of the things that compel people to attend NASCAR events, rather than watching them from the couch on TV. The front end of the Toyota Owners 400 at Richmond International Raceway was a whole lot quieter, though, because the 2016 Toyota Mirai made its debut as a pace car there. Outfitted with a light bar and a special livery, the Mirai became the first hydrogen fuel cell vehicle to ever pace a NASCAR race and led the cars to the green flag for Saturday night's Sprint Cup round. The sedan was tested prior to the event to prove it had the performance required to lead the 43-car field. "Bringing the Mirai to Richmond to pace this important race is another way for Toyota to showcase our innovation and environmental leadership," Ed Laukes, company vice president of marketing, performance, and guest experience, said. There's some precedent for Toyota to show off its green credentials to the NASCAR audience. In 2009, a Camry Hybrid paced the Coca-Cola 600. The automaker's fuel cell tech already had a maiden motorsport outing, too. Late last year, the FCV Concept, which previewed the Mirai, was the zero car to check the roads for the Shinshiro Rally in Japan. TOYOTA MIRAI TAKES TO THE TRACK 23/04/15 Mirai Will Pace Toyota Owners 400 at Richmond Mirai Is First Hydrogen Fuel Cell Electric Vehicle to Pace a NASCAR Race RICHMOND, VA. (April 23, 2015) – Toyota today announced the 2016 Toyota Mirai, a hydrogen fuel cell electric vehicle, will pace the Toyota Owners 400 NASCAR Sprint Cup Series race at Richmond International Raceway on Saturday night, April 25. Today's approval allows the Mirai to serve as the first hydrogen-fueled vehicle to pace a NASCAR race. It will lead the Sprint Cup Series field to the green flag at Richmond on Saturday night and emit only water out of its tailpipe along the way. "Having a hydrogen fuel cell vehicle pace the Toyota Owners 400 is a historic moment for both Toyota and NASCAR and we're proud it's the Toyota Mirai," said Ed Laukes, vice president of marketing, performance and guest experience, Toyota Motor Sales, U.S.A.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

Toyota to drop regular-cab Tacoma as small pickups take another hit

Even as General Motors prepares to redesign its midsize pickups, the market for sub-fullsize trucks continues to shrink. The remaining competitors in the segment are the well-aged Nissan Frontier, Honda Ridgeline and Toyota Tacoma, and now Truck Trend is reporting that the latter will be dropping its regular cab model due to poor sales.
According to the article, the available configurations for the Tacoma lineup will be whittled down in 2015, which apparently spells the end for the two-door Taco. The Tacoma is currently the last truck in its class to be offered in a regular cab configuration, with the Frontier no longer offering a standard cab model and spy shots of the next-gen Chevrolet Colorado not revealing any glimpse of a short cab, either.
