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 develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

Toyota highlights JDM Mark X with special Yellow Label edition

Never heard of the Toyota Mark X? That's because the Japanese automaker only sells it in its home market (and in China as the Reiz). It's a rear-drive (or all-wheel-drive) sports sedan about the size of a Lexus IS, whose existence is probably why Toyota will never bring the Mark X to North America. The current model has been on the market since 2009, but Toyota is rolling out a series of updates - including the new Yellow Label model pictured here.
Available on the 250G, 250G Four and 250G S trim levels, the Yellow Label gets a special shade of Awaken Yellow paint (though it can be had in black, white or silver as well), with an interior decked out in either yellow or black. It also gets piano lacquer trim, yellow stitching, pink gold accents, special tread plates and other interior equipment upgrades, as well as a unique set of alloys. All of which makes the Toyota Mark X Yellow Label perfect for recreating scenes from Kill Bill without the need to squeeze into yellow leathers. (In fact we wouldn't be surprised to see Toyota doing just that for a promo clip.)
Power comes from a 2.5-liter V6 (and not the larger 3.5 available on the 350S model) channeled through a six-speed automatic to either the rear wheels or all four. Pricing ranges between 2.8 and 3.1 million yen (~$26-30k), representing a premium of about 106k yen ($1k) over non-yellow models. Toyota operates four distinct dealer networks in Japan, and the Mark X is sold through Toyopet stores.
