I'm not a big fan of the new 6 speed TL, though I have never driven the CL-S 6 speed, so I really don't have any base line to comparing it. I hate the shifter, I would like it to be a little bit more direct feel. The clutch... both my dad and me had the problem to get used to that, could be the car I test droved didn't have enough break-in. I'm also very disappointed with the Brembo brakes too. Torque Steer is quite a problem for this generation and those so called performance Michellin doesn't help either. (I test drove the A-spec.)
Then we took the Automatic TL out without the A spec package, it's obviously slower but it's a lot more balanced, in wet cornering, I was able to "hauling" all four tires with 5 people in the car, and it poses a mind understeer while even a little bit of backing the throttle up will bring the rear end out and tighten the line... I'm impressed.
Well, I guessed I'm biased since I was driving my X there to test drive... Heck, I didn't even like the Evo8 for a bit... oh well.
