The engine features VVT-iE on the intake side while utilizing VVT-i (Variable Valve Timing with intelligence) for the exhaust, a highly efficient compression ratio of 13:1 (14:1 for the hybrid version) for increased thermal efficiency and fuel efficiency and a bore and stroke measuring 3.44 inches and 4.07 inches, respectively; the stroke has been increased from the previous 3.86 inches to achieve the higher compression ratio. Peak horsepower is estimated at 206 at 6,600 rpm (176 horsepower at 5,700 rpm in the hybrid configuration) with torque estimated at 186 lb.-ft. at 5,000 rpm (163 lb.-ft. at 3,600-5,200 rpm for the hybrid). Fuel economy is rated at an EPA-estimate of 29 mpg city/41 mpg highway/34 mpg combined), a 26 percent improvement for combined mpg over the previous model.
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.
The new Toyota Camry utilizes TNGA (Toyota New Global Architecture), which represents a completely new strategy to the way the company designs, engineers, and packages its vehicles. TNGA retains all of Toyota‘s traditional values of superlative build quality and safety while injecting a fun driving experience that plays on all the senses. The physical manifestation is the usage of a new engine, transmission and GA-K platform. "With an exhilarating design, refined interior, stirring driving performance, cutting-edge safety and technology, and class-leading fuel efficiency, the all-new Camry retains its excellent value while raising its level of fun and excitement to new heights," said Bill Fay, Toyota senior vice president of automotive operations. "It is, quite simply, the best Camry ever and the benchmark in the mid-size sedan segment."
Along with the traditional Camry Hybrid system drive modes of NORMAL, ECO and EV, a new SPORT drive mode setting has been added that allows for an increase in power from the hybrid system for improved acceleration response relative to pedal input. The NORMAL, ECO, and SPORT modes can each be used while EV mode is activated. The Toyota Camry Hybrid also features the new Auto Glide Control (AGC), which helps to improve fuel efficiency by calculating an efficient coasting logic. When driving normally, engine braking will slow the vehicle down when the driver lifts off from the accelerator pedal. However, to avoid aggressive engine braking, AGC limits the loss of vehicle speed through an automatic drive setting that acts more like a neutral gear, allowing the vehicle to coast to the stoplight.
