Like the 2.5-liter inline 4-cylinder Dynamic Force Engine, the Camry’s newly-developed 3.5-liter V-6 is equipped with the highly-advanced D-4S direct injection system, along with a specially-developed new VVT-iW (Variable Valve Timing-intelligent Wide) variable valve timing system. Thanks to the addition of these highly efficient engine technologies, it delivers higher power output, and class-leading fuel efficiency.
The 24-valve DOHC 3.5-liter V-6 engine employs the VVT-iW system for the intake, with VVT-i (Variable Valve Timing - Intelligent) on the exhaust, an efficient 11.8:1 compression ratio and a more squared bore and stroke of 3.70 inches and 3.27 inches, respectively, in comparison to the longer stroke of the Camry’s new 2.5-liter inline 4-cylinder power plant.
Power output is rated at 301 horsepower at 6,600 rpm an impressive torque rating of 267 ft.-lb. at 4,700 rpm. Despite its exceptional power output, the new 3.5-liter V-6 engine achieves exemplary fuel efficiency with an EPA-estimated rating of 22 mpg city/33 mpg highway/26 mpg combined, an increase of eight percent for combined mpg over the previous V6.
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.
Direct Shift Eight-Speed Automatic Transmission
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.
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.
