The Lexus IS F features an 8-speed Sport Direct Shift (SPDS) automatic transmission with sequential shift which can lock-up the torque converter from 2nd through 8th gears (see also: Lexus IS transmission specifications). The SPDS is derived from the unit introduced in the 2007 Lexus LS, which was the first vehicle to carry an 8-speed transmission. [34] The SPDS allows for shifts to occur in 0.1 s (100 ms), [35] compared to 0.05 s (50 ms) of F1 race cars. [36] The wheel-mounted paddle shifters allow for gear shifting while steering, and a manual mode can be selected for added control. The 8-speed transmission also improves fuel economy, [37] with lower overall consumption than BMW, Mercedes, and Audi rivals, [35][37] and avoidance of the U.S. Gas Guzzler Tax. [38] |
