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.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.

Toyota FT-86 Open Concept leaves us feeling flushed

When last we checked in on our topless would-be hero, the Toyota FT-86 convertible had been reportedly placed on "indefinite hold." That was back in early October, not long after Toyota had trotted out the rear-wheel-drive canvasback to Scion dealers as a possible future product carrot if they decided not to turn in their franchises. And yet, we're here at the Tokyo Motor Show, where Toyota has taken the time to at least repaint the FT-86 Open Concept in "Flash Red," if not build a whole other car (the original Geneva showcar was white). It's enough to make our heads spin like a teenager on the verge of a breakup. Will they? Won't they?
At this point, we still don't know any more than you do - the last word we heard out of Toyota was not encouraging, although the story was that the program could still be fast-tracked if management had a change of heart. As the car has never been seen before in Japan, perhaps Toyota is merely extending its domestic audience a courtesy view before it lines this showcar in mothballs, or maybe they're still trying to make a decision on its fate and gauging public reaction on the homefront.
Interestingly, in a new story published today, Automotive News quotes Subaru brand boss Yasuyuki Yoshinaga downplaying the likelihood of a production model, saying flatly "We make the car, so if we don't make it, it can't happen." The executive went on to note, "Our engineering department told me that losing the entire roof requires a complete redesign of the structure. It would need a big change." Given that such a car would probably trade in rather small volumes, that sounds like a significant hurtle.
