MotorWeek remembers retro icons, Supra and NSX

It's easy to poke a joke here and there about John Davis, the long-time host of MotorWeek. His voice is so monotonous that, from time to time, if you closed your eyes, you may think it's generated via a computer. But you have to give him and the rest of the show a lot of credit. The program has been on the air for decades, giving people direct, straight-down-the middle automotive reviews.
MotorWeek's massive back catalog of reviews are slowly making their way onto YouTube, and they provide a fascinating chance to look back on how performance cars rank against their contemporaries from back in the day. Two recent additions include the show's old looks at the 1986 Toyota Supra, the dawn of the third-generation model, and the now-iconic 1991 Acura NSX.
Both reviews are interesting in their own way. These days you hear nary a negative word about the original NSX, but MotorWeek isn't afraid to point out a few flaws. And the Supra really shows the progress of suspension tuning in the intervening decades because it has some serious body roll in the corners. Scroll down to check out both videos and get a blast from the automotive past.

Toyota recalling 20k 2014 and 2015 cars and CUVs with 3.5L engines

Toyota has announced a recall of roughly 20,000 vehicles covering the 2014 Avalon, Camry, Highlander (pictured) and Sienna, as well as the 2015 Lexus RX luxury crossover. The affected vehicles are all powered the 2GR-FE engine, which in layman's terms, is Toyota's well-regarded 3.5-liter V6.
According to Toyota's statement, a parts supplier might not have welded "the end cap on the right-hand fuel delivery pipe in the engine compartment" correctly, meaning fuel could leak. Leaking fuel, of course, increases the chance of an engine fire. That said, no fires, crashes or injuries have been reported due to the issue.
Owners will be notified to report to dealers, where techs will check the fuel delivery pipe and fit a replacement part as necessary.

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.
