The Toyota MR2 has a opitionl 6 speed sequential AT. I think that is kind of neet. I know the Acura TL S-type has that. I Think it the 6 had this option this is what I would go with because I do a lot of stop and go traffic.
What does it mean by sequential automatic transmission? I have read about it in a few places but I dont really know what it means. At first I thought, it was an automatic with the option to shift manually...like the sportshift of the 6.
In a true sequential automatic (aka automanual, Semi-manual gearbox, etc.) you have a manual gearbox that requires a clutch (just like in a manual car). The clutch is electronically controlled. When you press the buttons (or paddles) the clutch is activated and changes the gear for you. This system is derived from the ones used in high end racing events (read NOT NASCAR).
A sportshift automatic (aka tiptronic, manumatic, etc.) is an automatic transmission with a torque converter (aka torque robber) that has an electronic control that allows you to manually choose which gear is robbing you of torque at any given time.
The MR2 has the electronic clutch, it's a toned down, Toyota developed system like the BMW M3 has. As you shift, the computer engages the clutch for you. Unfortunately, when I read the review on it, they praised the BMW version for having 6 different "feels", like sport, cruising, ect, while the toyota has one setting. Said it wasn't as fun as the BMW version, but it's also $30000 less for the car.
