General Motors and Segway unveiled a prototype two-seat electric scooter today, intended to ease urban congestion and pollution and help GM recast itself as environmentally progressive and technologically innovative. The vehicle, named Puma (for Personal Urban Mobility and Accessibility), is the product of an unlikely collaboration between an ailing American industrial behemoth known for manufacturing gas-guzzlers and a privately held company founded on technological wizardry.

A Hummer H1 converted to use biofuels - it can run on either vegetable oil or biodiesel. You'll still burn tons of gas, but at least you can make it yourself if you want to.

Jim Taylor has left his position as a CEO at Cadillac to become CEO of HUMMER as GM is still in the process of selling the SUV brand. We don’t know if that’s a smart move by Taylor or a dumb move - but that all depends on the future of the General.

You may have seen our In the Autoblog Garage report from earlier today about a very unique car: the KITT Shelby GT500 KR. When someone offers you the keys to what is essentially a supercharged V8-powered prop, you make the most of your time together.

Well, that didn't take long. A company by the name of Auto Tech Plastics has gone and done what seemed inevitable and many a blogger feared would happen: endow the new Ford Flex's slab-sidedness with fake woodgrain. Make no mistake, we have absolutely no problem whatsoever with the classic woody wagons from a bygone era. Sure, they may take a bit more upkeep than normal, but the classic models with their real wood paneling are just fine by us.

Following the closure of his Sprint Cup ride last month, Dario Franchitti will run several races in the second-tier Nationwide Series before the end of the season. The Scottish driver was reportedly offered several options by Chip Ganassi, and chose to concentrate on NASCAR rather than move back to open wheels or elsewhere.

To say that HUMMER's launch timing for the H3T sport-utility-truck couldn't be worse seems like an understatement. Trucks which had been flying out of showrooms just a few short years ago are now languishing on dealer lots. What's more, the entire HUMMER brand could get the axe any day now from (current) parent company General Motors. Still, the H3T is coming to a dealer near you in September, and there's nothing that the General can do but price it competitively and hope for the best.

Not to mention any names or anything (*cough* Baja *cough*), but there have been some downright ugly trucks to go from the concept stage straight through to production. Usually, though, consumer reaction is properly gaged and the most egregious styling mistakes are usually swept quietly under the rug. Until, that is, somebody starts digging around for the most grossly misshapen models they can find...

It sure ain't pretty, though beauty, in this case, is likely in the eye of the beholder. A few years back, a new take on the taxi was provided by Standard Taxi, a company based in Troy, Michigan. The design for the purpose-built people hauler uses GM running gear and is able to haul four passengers in relative comfort. We hadn't heard a peep from the company until today when we learned that Standard is now working on negotiations with AM General to build the vehicle in its plant in Mishawaka, Indiana, where AM General builds the Hummer H2 SUV and SUT.

There's no official obituary for GM's HUMMER brand yet, but haters are lacing up their dancing shoes while lovers wring their hands. Dealers with HUMMER franchises have a lot of skin in the game, so the uncertain future is bound to give business officers ulcers. Not willing to wait around to the bitter end, Milwaukee's Bergstrom HUMMER is planning to move into the same space as the group's Chevrolet store. The HUMMER-specific Quonset hut style dealership building will be toned down and pressed into service as an outlet for Certified used GM vehicles.

This is a very interesting scenario. SUVs powered by big gasoline engines are becoming unpopular in the U.S, thanks to sky-rocketing crude oil prices that threaten to destroy the conventional car itself. GM has been posting record losses on a regular basis and to stop the bleeding to some extent, it planned to push off the Hummer brand, one of the main culprits.

We did the pre-run, now it was time for Autoblog to race the Baja 500 with driver Chad Hall and Team HUMMER. Our race day start time wasn't until 10:30, but we got to the start line at 8:30. And then we signed autographs and kissed babies. Well, Chad didn't, but people kept asking us for our autograph, so we obliged. Kids also constantly asked for "steeckers," but we didn't have any of those... Follow the jump to see how Autoblog fared as racing co-pilot, and be sure to check out the gallery of hi-res images below and the insane in-truck video after the jump.

Has Hummer had its day? Sales of the all-American company’s models have slumped by nearly one-third, as US buyers lose their appetites for supersized cars. And bosses at owner General Motors have now officially confirmed Hummer’s future hangs in the balance.

The scholars over at Automobile magazine have handed out their "Funky Ergonomics Awards" this year. As expected, BMW's iDrive and 7 Series interior (shown above) remains their favorite pincushion. Rightly so. Their list includes convenience keys that are downright inconvenient, window switches that are out of reach, touchscreens that are dangerously slow to respond, all center-of-the-dashboard mounted instrument clusters, complicated navigation systems, reverse-action manu-matic transmissions, and dimly lit interiors.
