2017 Toyota Highlander – footage. The Toyota Highlander V6 has steadily made strides in performance over its lifespan, but for 2017, the powertrain upgrade is perhaps the most dramatic. The new 3.5-liter D-4S Injection V6 pushes output to 295 horsepower and 263 lb.-ft. of torque, which represent increases of 25 hp and 15 lb.-ft., respectively, over the 2016 Highlander V6. The new V6 also becomes the base engine for the Highlander Hybrid and features Dual VVT-i.
Making best use of the engine’s upgraded performance and efficiency, the V6 Highlander now employs a new Direct Shift – 8AT 8-speed automatic transmission. The eight ratios, compared to six in the 2016 V6 model, benefit the Highlander’s acceleration and passing abilities. Both the engine and transmission incorporate new advances in friction reduction, while the transmission delivers a more direct driving feel and higher level of efficiency by expanding the torque converter lock-up range. Fuel economy for all-wheel drive models improves to an EPA-estimated 20 mpg city/27 mpg highway, versus 18/24 for the 2016 model.
