The unit‘s gear ratios have been carefully selected for enhanced power delivery as well as optimal fuel efficiency, with the mid-range gears utilizing close ratios to improve passing power. The new gearbox also includes a torque converter that offers a wider range of lock-up (when compared to the previous 6-speed automatic transmission) for a more direct driving feel while contributing to improved fuel efficiency through suppressed engine revving. Other impressive features engineered into this 8-speed automatic transmission include new control logic, for more precise matching of engine torque, and smoother transitions when downshifting.
Building on the Camry‘s undisputed reputation as an extremely smooth and quiet car in its class, Toyota engineers incorporated a variety of new noise, vibration and harshness (NVH) countermeasures that were previously found exclusively on luxury models. These include sound absorbing/insulation through the fitment of a hood insulator and upper and lower fender separator. The passenger compartment is further insulated from the engine and road noise using foam/vibration dampening materials throughout the vehicle along with a thicker dash silencer mat across the entire interior firewall section. Furthermore, a special vibration-damping coating has been applied over a wider area of the underfloor, joined by noise-proofing material encompassing more surface area of the interior‘s ceiling. Wind noise has been suppressed through a newly-designed rain gutter molding and a reduction in the step at the bottom of the windshield.
The V-6’s VVT-iW variable valve timing system has been engineered to ensure high torque production at all engine speeds. It utilizes the Atkinson cycle to enhance fuel economy without sacrificing performance or engine start ability at extremely low temperatures as well as in wide-open throttle (WOT) engine operation. Fuel efficiency is further enhanced by decreasing pumping losses from the delayed closing of the intake valves. Both the 2.5-liter 4-cylinder Dynamic Force Engine and the 3.5-liter V-6 are equipped with the new Direct Shift 8-speed automatic transmission that allows the driver to freely experience the direct and impressive acceleration capability of the engines, along with the satisfyingly crisp-yet-smooth, quick-shifting capability of a performance-oriented gearbox. What‘s more, not only does this transmission deliver outstanding fuel economy, it also always operates within a calm and refined manner.
