About ATTS on Honda Prelude
The Active Torque Transfer System (ATTS) was a feature in the fifth generation Honda Prelude, specifically in the Type SH (Super Handling) models in the US and VTI-S models in Europe. The system was designed to neutralize the notorious front-wheel drive (FWD) understeer, and it achieved this by using computer-controlled clutches to distribute torque to the outside drive wheel during cornering. In addition to the ATTS unit, Honda also made changes to the shocks, springs, front lower arms, and sway bars of the Type SH/VTI-S Preludes, resulting in noticeably better handling than the base model. The ATTS system was especially helpful and apparent in long sweeping corners. The system ceased production along with the Prelude in 2001, but its legacy remains, as the praised SH-AWD system has found its way into various Acura and Honda vehicles in recent years.
The ATTS system was not without its issues, as some users reported problems such as the ATTS light coming on without any stored codes, which could indicate common problems with the system. Additionally, there were discussions about the compatibility of the JDM ECU with the US ATTS ECU, and the system’s interaction with other components like the LSD (limited-slip differential) ,,.
The ATTS system was particularly notable for its contribution to the handling of the Prelude, providing enhanced rear-wheel-drive-like cornering ability while retaining the traditional benefits of front-wheel drive. It was a pioneering technology that previewed modern systems like Acura’s Super Handling All-Wheel Drive and generated numerous patents for Honda.
In summary, the ATTS was a significant feature in the Honda Prelude Type SH and VTI-S models, designed to improve handling by addressing front-wheel drive understeer through the use of computer-controlled clutches to distribute torque during cornering. Despite its discontinuation, the system’s legacy continues to influence modern vehicle technologies ,.
