SH handling?
I was watching this thing on the Honda site about their SH-AWD handling, which is on the RL right now, and possible the next NSX replacement. But they said they put the first generation SH technology on the 98 Preludes. Anyone know if the CL's have this "SH" system?

It hasn't been confirmed but many people have assumed that the automatic CL-S has something a little different than your run of the mill open differential. Mainly because you can lay down two streaks of rubber (something you can't do with a true open differential and the way the car handles in the corners (it doesn't smoke the inside wheel). Not a true LSD like you find in the 6 speed but basically a similar idea. It worked quite well too at reducing understeer.
The new RL has the same system as the Prelude SH but the system is found at the rear as well as the front.

The CL's never had the SH system. On the 97-00 Preludes, they had what was called the ATTS (Active Torque Transfer System). That model was called the Prelude Type-SH (for Super Handling).
Bascially it transferred the torque from the inner wheel to the outer wheel in a turn in order to make the FWD car turn quicker, and negotiate twisties like a RWD vehicle.
Always wanted one, but at the time $25K was too much...
edit: However as mrsteve mentions above, the 6MT CL did come with an LSD which is not the same thing as the ATTS system.

^ The time limit expired, so I'll just attach this post highlighting the differences that another member for the TL forums mentioned.

Correct. I didn't say it was a true LSD (and I know you weren't disputing the information I gave) but I'd be willing to bet the automatic CL-S has a similar system. In fact when different companies were opening up the transmissions to beef up the internals they said it didn't need an LSD because it already had more than your run of the mill open differential.

The good thing about the SH-AWD is that the display shows the amount of power going to each wheel ~ simply awesome.
It also allows for slight oversteer which made me laugh my ass off since it was a surprise! I then proceeded to keep pushing the limits & let me tall ya... it works really really well. Impressive to say the least.

Yeah from what I was told the new RL really shines when you push it hard. In day to day driving you can't tell it's even there.

simple question.... simple answer..
the 1st nor 2nd generation CL-S does NOT have the SH system.maybe the 3rd Gen... if we ever see it..

From Edmunds.com
Reeling in all that power is a helical limited-slip differential that is essentially the latest version of Honda's Automatic Torque Transfer System, or ATTS, that was first seen on the 1997 Prelude Type SH. Although ATTS was never the sales and marketing hit Honda had hoped for (as seen by the low sales numbers and eventual termination of the Prelude model), anyone who experienced this subtle technology on a twisty road, or under racetrack conditions, quickly came to appreciate Honda's high-tech efforts. It works by sensing and reducing wheel slip of the inside tire while simultaneously sending additional torque to the outside tire during cornering maneuvers. This allows the driver to accelerate sooner when exiting a turn, and the "pulling" effect of applying additional torque to the outside front tire can almost make you forget which wheels are propelling the CL Type-S. In other words, the car feels strangely similar to a certain rear-wheel-drive sport coupe known for its "driving passion."
