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's Copen GR Sport is a tiny, racy roadster

In its home market, Toyota has a designated sport brand called GR, which is meant to invoke Toyota's Gazoo Racing division. It has three tiers of sportiness: the entry-level GR Sport, GR, and all-out range-topping GRMN. Ahead of the Tokyo Motor Show, Toyota announced it is adding to its GR Sport lineup a new mini convertible called the Copen GR Sport. Toyota pulled the Copen from Daihatsu's bank of cool minicars. Diahatsu announced its own Copen GR Sport at the Tokyo Auto Salon in early 2019. Now Toyota will sell its own hotted-up version of the tiny roadster. Toyota Gazoo Racing tweaked the new model and gave it sportier equipment and a visual update inside and out. First, let's talk basic stats. The Copen GR Sport weighs roughly 2,000 pounds and has a 0.66-liter turbocharged engine that makes 63 horsepower at 6,400 rpm and 68 lb-ft of torque at 3,200 rpm. It's front-wheel drive and is available with a five-speed manual or a continuously variable transmission (CVT) with seven-speed Super Active Shift and paddle shifters. Toyota left the powertrain alone and chose to focus on body rigidity and suspension tuning. The Copen GR Sport has specific shock absorbers, updated spring rates, retuned power steering, a new front brace, and a redesigned center brace.  Toyota made the Copen a bit more visually aggressive as well. It has a unique front bumper with side air intakes, a larger front grille, and a rear bumper with a new diffuser look. It also comes with matte gray BBS forged-aluminum wheels, LED headlights, LED fog lights, and LED taillights. GR Sport emblems on the front, side, and rear assure passers-by this is not a regular Copen. In total, eight exterior colors are available, as are multiple color options for the roof. The black interior was spruced up with Recaro sport seats with GR embroidery, a MOMO leather-wrapped steering wheel with the GR emblem, piano black accents, and a new GR instrument cluster with red accents. Unfortunately, the pint-sized roadster is only available in Japan.

Anti-EV messaging alive and well at Toyota, sort of

The folks at Toyota in Japan can be pretty blunt about electric-vehicle technology prospects as a viable transportation alternative to the internal combustion engine. Here in the states? Slightly more sanguine. Toyota global head of research and development Mitsuhisa Kato, according to Automotive News, discounts the potential of substantial EV sales in the near future because the appropriate technology that provides comparable driving distances and fill-up times relative to conventional vehicles doesn't yet exist. While Toyota has been conducting testing programs with shorter-commute-distance EVs in countries such as Japan and France, its only production EV in the US is the RAV4 EV, and Toyota sold just 546 of those in the States during the first half of the year. Toyota is much more excited about the debut of its first hydrogen fuel-cell production vehicle, in both Japan and the US, next year. Toyota Motor North America spokeswoman Jana Hartline was a little more charitable when discussing the EV's prospects in an interview with AutoblogGreen. "For shorter range, EVs serve a really great purpose, but as far as having equal mile range to an internal combustion engine, there's going to need to be some serious breakthroughs," Hartline said. "And that where the fuel cell comes in." Last month, Toyota said its fuel-cell sedan that will debut in Japan next April will be priced at about $69,000, though the company emphasized that it shouldn't be assumed it will be priced similarly in the US and Europe. Toyota hasn't released many performance details, though the sedan is expected to have a full (hydrogen) tank range of about 435 miles, or about five times that of a Nissan Leaf.
