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.

Brand new cars are being sold with defective Takata airbags

If you just bought a 2016 Audi TT, 2017 Audi R8, 2016–17 Mitsubishi i-MiEV, or 2016 Volkswagen CC, we have some unsettling news for you. A report provided to a US Senate committee that oversees the US National Highway Traffic Safety Administration (NHTSA) and reported on by Automotive News claims these vehicles were sold with defective Takata airbags. And it gets worse. Toyota and FCA are called out in the report for continuing to build vehicles that will need to be recalled down the line for the same issue. That's not all. The report also states that of the airbags that have been replaced already in the Takata recall campaign, 2.1 million will need to eventually be replaced again. They don't have the drying agent that prevents the degradation of the ammonium nitrate, which can lead to explosions that can destroy the airbag housing and propel metal fragments at occupants. So these airbags are out there already. We're not done yet. There's also a stockpile of about 580,000 airbags waiting to be installed in cars coming in to have their defective airbags replaced. These 580k airbags also don't have the drying agent. They'll need to be replaced down the road, too. A new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time. If all this has you spinning around in a frustrated, agitated mess, there's a silver lining that is better than it sounds. So take a breath, run your fingers through your hair, and read on. Our best evidence right now demonstrates that defective Takata airbags – those without the drying agent that prevents humidity from degrading the ammonium nitrate propellant – aren't dangerous yet. It takes a long period of time combined with high humidity for them to reach the point where they can rupture their housing and cause serious injury. It's a matter of years, not days. So a new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time – and six years seems to be about as early as the degradation happens in the worst possible scenario. All this is small comfort for the millions of people who just realized their brand-new car has a time bomb installed in the wheel or dashboard, or the owners who waited patiently to have their airbags replaced only to discover that the new airbag is probably defective in the same way (although newer and safer!) as the old one.

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.
