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.

TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!

Next Toyota Prius coming in 60-mpg 'Eco Grade' version?

There's some mystery surrounding the fuel economy level of the next-generation Toyota Prius. The closest we've had to an official number is 55 miles per gallon, which was hinted at by Toyota Motor Corporation's managing officer, Satoshi Ogiso, last year. That number wasn't an official target, but the company even provided a graphic (above) showing how each next generation Prius beat the previous one by four or five mpg. Since the current, third-gen model gets 50, well, we have been left to guess that 55 is the next logical target. But, according to a new report in Automotive News, the new, fourth-generation Prius that's due next year will come in two versions, with one having a bigger ego – sorry, eco – than the other. AN says that the model will arrive with a standard nickel-metal hydride battery pack in a version that gets "about 55 mpg" and then a new "eco grade" version with a li-ion battery that "will be rated at more than 60 mpg." AN says this information came from company executives who were speaking at an August meeting with Toyota dealers. Our sources within Toyota say that they haven't heard anything about two high-efficiency models, so we'll take this with the requisite grain of salt. The current version of the Prius Plug-In Hybrid does use lithium-ion batteries, but this is the non-plug model the dealers are talking about. We think. The dual-battery strategy is certainly a rumor we've heard before. We had thought that the li-ion pack would be for an extended EV range (the current Prius has a barely noticeable EV-only range), but such a pack would be lighter and could boost efficiency, too. In other words, we look forward to hearing more during the upcoming auto show season.
