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.

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.

Cosworth teases upgrades for Subaru BRZ

Subaru may or may not produce an STI version of the BRZ. Things seem to go back and forth on the subject. But Subaru Tecnica International isn't the only company with a history of tuning Subies. So does Cosworth, and now the British racing firm appears to be turning its attention to the BRZ and its Toyota- and Scion-badged siblings.
For those unacquainted, Cosworth is more than your average tuning company. It's a racing firm first and foremost, having made F1 engines under its own name as well as Ford's (chief among them the all-conquering DFV 3.0-liter V8 of 1960s and 70s fame), not to mention engines for Indy, rally and even high-performance, road-going versions of the Ford Sierra, Chevy Vega and Mercedes 190E. The list goes on and on, but you get the point.
Now withdrawing from Formula One, Cosworth is focusing its attention on tuning road cars again with the launch of the Cosworth Power Package line, the first of which will focus on the Toyota GT86 (aka Scion FR-S) and Subaru BRZ. We don't know just yet what will be included in the packaged dubbed FA-20, but from the video teaser below, it seems there'll be upgrades to the exhaust, suspension, aero and - if we're lucky - maybe a super- or turbocharger for the 2.0-liter flat-four engine. We'll have to wait and see, but we get the feeling that with Cosworth on the job, it'll be worth the wait. Check out the minute-long video below in the meantime.
