Scion reveals iM concept ahead of LA debut

After dropping a teaser image on us a few weeks ago, Scion has revealed in full the new iM Concept it's bringing to the Los Angeles Auto Show next week. As expected, the concept is clearly a rebadged version of the Euro-market Toyota Auris, only with some "European Racing Circuit Styling" upgrades to make it look more aggressive.
Along with the Scion logos, the five-door hatch is treated to a deeper air dam flanked by angular vents with stacked fog lamps, beefed-up wheel arches linked by widened side sills and filled with 19-inch, anthracite-finish alloys on low-profile rubber. Vented brake discs and four-piston calipers join an adjustable suspension as show-worthy equipment upgrades.
The sporty treatment continues around back with a similarly aggressive rear bumper and roof spoiler. Even the wing mirrors are replaced with narrower units. Little wonder it's all done up in a shade Scion calls "incrediblue" that looks rather similar to what sister-brand Lexus would put on one of its F-branded performance models - or for that matter what corporate ally Subaru would put on an STI hot hatches like the WRX.

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:

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.
