I test drove a TRD Sport 6MT the other day. VERY nice driving experience.
It looks like they got rid of that accumulator thingy from the 3rd gen Tacoma. I had a 3rd gen MT briefly and really didn't like that MT at all as it seemed impossible to get into gears smoothly no matter how you tried to feather out the clutch after a gear shift. The clutch in this truck was easy, the shifts aren't too long, and I don't see the rev hang to be a problem. You may think differently if you're trying for performance and are trying to accelerate and shift as fast as possible. Engine had plenty of power (it makes its peak torque at 1700rpm), and I think Toyota fixed the undriveability of the 3rd gen where the engine and the transmission hated each other in the automatics. I had the windows down slightly, and while some won't be able to get over the sound of a turbo I4 (the Colorado engine sound wasn't good as well, IMO), you could definitely hear that turbo under normal loads, which I thought was cool. Bottom line was I didn't want to take the truck back to the dealership. I would buy one based on that test drive, although I know the price point is going to turn many people off. But that seems to be the story with all new vehicles these days...
