Expedition drives from Russia to Canada over North Pole...

No, a Ford Expedition did not drive from Russia to Canada via the North Pole, but that's exactly what a team of intrepid explorers accomplished recently. Using specially-modified buses with massive tires, the group slowly drove 2,485 miles in 70 days over drifting ice, occasionally using a pickaxe to clear a path and staying on guard for chasms that could open up and plunge the team into the frigid arctic waters. Average speeds were about 6 mph, "at the speed of a (farm) tractor." While the big tires technically allowed the buses to float if the need arose, the team preferred to stay out of the water to keep the suspension from getting coated in thick, hard ice. Falling in on foot would mean almost certain death.
According to Phys.org, the buses were powered by Toyota diesel engines, but were built with prototype parts from a previous driving expedition to the North Pole. Right now, the machines are parked in a garage in Canada's Resolute Bay while the the team rests up with family back home. They plan to continue their trek to back across the Bering Straight to Russia. If successful, the team may eventually offer a version of their buses for commercial sale.

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 prices fuel cell sedan $70K in Japan, coming to US and Europe next summer [w/video]

Toyota has finally unveiled its FCV hydrogen fuel cell sedan and its Japanese price. We won't have to wait too long to see the first of these revolutionary vehicles on the roads. It will go on sale in Japan in April 2015 and will come to the US and Europe later that summer.
In Japan, the FCV will be priced at roughly 7 million yen before taxes ($68,810 at current exchange rates). However, Toyota makes it clear in the press release that we shouldn't try to extrapolate US MSRP from that figure, saying that official pricing for the US and Europe has not yet been determined. As will be the case in the US, sales in Japan will be limited to parts of the country that already have a hydrogen refueling infrastructure (that means you, California).
The production version of the FCV looks almost identical to the concept from last year's Tokyo Motor Show. There is a new vertical strip of LEDs at each corner of the front air intake and real sideview windows, instead of the nubs on the prototype. The weird squiggles from the rear trim are also gone in favor of a more production-ready look, but the taillights survive the changes mostly intact.
