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.
Dynamic performance is assured thanks to optimal control of the engine working in concert with the electric motor (MG2), while exemplary energy efficiency is achieved by using both electric motors (MG1 and MG2) for hybrid battery charging. Driving characteristics and trunk room are improved through the implementation of the new TNGA packaging as it allows for the hybrid system’s battery pack to be moved from the trunk area to beneath the rear seat, positioning the battery weight at a lower center of gravity axis. The updated Power Control Unit (PCU) of the new hybrid system plays a key role in improving the operational efficiency of this eco-sensitive powertrain. Thanks to improvements in the conversion efficiency of the PCU and the transaxle/electric motor, they combine to reduce energy loss by a total of approximately 20 percent. Additionally, improvements to cooling system efficiency has reduced energy loss by about 10 percent.
The new front seats have improved ergonomics, providing maximum comfort with a newfound level of ease and engagement to match the Camry’s elevated performance and athleticism. Rear-seat accommodations are more refined than ever too, with improved comfort and ergonomics. Exquisite stitching on the front- and rear-seat surfaces is but one example of the high level of craftsmanship found throughout the vehicle. Development of the all-new Camry has been advanced by Toyota‘s company-wide implementation of Toyota New Global Architecture (TNGA). TNGA builds upon Toyota‘s engineering and design strengths to make every new vehicle even better, with the all-new Toyota Camry being the first vehicle to take full advantage of the new architecture for creating fun-to-drive vehicles.
The all-new Camry’s TNGA-based body/platform has created a new dimension of design freedom that includes an extended wheelbase and a wider vehicle stance, realizing a stylish and sporty new design aesthetic. Along with the new platform, an all-new 2.5-liter four-cylinder Dynamic Force Engine, new Direct Shift-8AT eight-speed automatic transmission and a new double wishbone rear suspension design are all representative technologies that have evolved through TNGA. The most noticeable change for the driver will be that TNGA will deliver an unprecedented level of driving enjoyment through dynamic and spirited handling capability.
