Does Scion's LA concept presage a US Auris?

When the doors open at the LA Auto Show in a few weeks, Scion will be on hand to showcase its new iM Concept. But considering what little Toyota's youthful brand has revealed about the concept so far, it's led to rampant speculation. And the prevailing wisdom seems to point towards a production iM arriving as a Scion-badged version of the Toyota Auris.
For those unfamiliar, the Auris is to European (and other) markets essentially what the Matrix is (was?) to ours: a hatchback version of the Corolla. The model line was first introduced in 2006, looking in its first iteration like an overgrown version of the contemporary second-gen Yaris, and was replaced with the current model in 2012. It's available as a five-door hatch or wagon, with a range of gasoline, diesel and hybrid powertrains available.
If the rumors - spurred by the similarity of the iM concept's nose depicted in the teasers - prove accurate, and public reception to the idea ends up spurring Toyota to put it into action, it wouldn't be the first overseas Toyota brought over as a Scion. The Scion iQ was sold as the Toyota iQ overseas years before it arrived here.

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.

Toyota asking NHTSA for fuel cell car safety exemption regarding electric shocks

Toyota is requesting an exemption from federal safety regulations that govern electric cars as it prepares to launch a small-scale hydrogen fuel-cell vehicle fleet.
The Japanese automaker is targeting Federal Motor Vehicle Safety Standard 305, which covers the packaging of high-voltage parts in electric cars. According to Uncle Sam, these systems need to be isolated so that passengers and first responders aren't electrocuted in the event of a crash. That seems pretty smart, but it's become a problem for Toyota's upcoming production fuel cell vehicle, as the mechanism that prevents electric shocks in low-speed crashes will apparently simply keep Toyota's car from even functioning.
Instead of the federally approved system, Bloomberg reports that Toyota plans to insulate the high-voltage wires and cables in the car, along with shielding electrical components like the fuel cells, electric motor and batteries with (presumably non-conductive) metal barriers.
