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.

Honda, Nissan and Mazda recalling 3 million vehicles for airbag inflators

Three million more vehicles can be added to the worldwide tally to be repaired for the faulty airbag inflators supplied by Takata. Honda, Nissan, and Mazda have all issued recalls to replace the bad part, including about 1.2 million of them in North America. NHTSA has been investigating all three companies, plus Chrysler and Toyota, for potentially affected vehicles.
Honda is recalling roughly 1.02 million Civic, CR-V, Odyssey and Element models In North America, built between April 2000 and October 2002. Mazda needs to repair 14,794 units of the RX-8 and Mazda6, and Nissan has 228,000 vehicles in North America to be fixed.
Chrysler is also starting what it calls a "regional field action" to replace the inflators in the 2006 Dodge Charger, according to a company spokesperson. The company says that it has not yet found the problem in any of its vehicles, but it's being done "out of an abundance of caution." The final number of Chargers affected will be announced later this week.

24 Hours of Le Mans live update part one

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice with a profanity-laden stream-of-consciousness writing style. Parker lives in Hawaii and spends far more time spearfishing than behind the wheel of a car. Jump ahead to Part Two here, and Part Three here. Big Money and billionaire hobbyists and rockets on wheels. Jets belching French color smoke overhead. Balance of power fuckery. Plenty of water on the ground this morning. Absurdly expensive motorcars lined up in the pissing rain. Fast twitch lunatics behind the wheel. Chomping at the bit. Let's go let's go let's go! Race hasn't even started, Ford #67 maybe dealing with clutch issues. Karma? That beautiful bastard Brad Pitt's out on the track, waving the tricolor flag. It's a standing start in "Noah's Ark" weather and the 2016 24 hours of Le Mans is go! First lap takes place behind the safety car, finished in a record setting 8 minutes 27 seconds. Wrong kind of record maybe, but this is the first time I've set my mind to watching the whole damn race. Feel like I'm part of history. 3:00 AM on Kauai, a little too early for life. Sucking down coffee like a maniac. Don't fall back asleep. Got my hands on four hours of rest, how much more can I need? Better be enough for the next twenty four hours. Gonna get kinda punchy toward the end. Jason Statham on the scene. Four feet of solid muscle, non-existent hairline. Lovely wife peanut gallery sitting next to me calls him the "best race car drive in the world." Not sure if she's serious. Toss up, could go either way. Statham's a funny guy. Heir to the Bruce Willis comedy action crown. Really good in the movie where the fat comedy lady plays a spy. Ford's on the road. Problems with gearbox pressure, apparently. Nearing a half hour in and the safety car is still on the track. Hellish amounts of water on the ground, in the air. Visibility is garbage. Getting better. Twitter wags, "Not with a bang but a whimper." Just building suspense. Mother Nature felt like killing some people today, race officials need to dial back the drivers until it dries a tad. Normal inclination would've seen 'em flying, guaranteed early lap wrecks. Sad news for that bloodthirsty part of my lizard brain I try and keep suppressed. Good news for humanity. #12 in the pit for a bit.
