2018 Toyota Camry - TNGA-Inspired 2.5-Liter 4-Cylinder Dynamic Force Engine


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.   

Through TNGA, the Camry now has an ideal driving position for the driver—allowing for better concentration on the road ahead while helping to reduce driver fatigue—along with improving the overall seating position for all the vehicle’s occupants. Thanks to these changes, plus the reconfigured lower beltline height and the more integrated design of the instrument panel, the driver and front passenger will experience more expansive outward visibility. Lateral visibility for the driver is enhanced, thanks to a repositioning of the A-pillars and side view mirrors; this design reconfiguration further aids the sense of openness for both the driver and the front passenger.

More Power With Class-leading MPG 
Three new powertrains will be available on the new 2018 Camry: They include an all-new 2.5-liter inline-four-cylinder D-4S gasoline engine and a new 3.5-liter V6 with D-4S Fuel Injection, both of which are paired to a new eight-speed Direct-Shift automatic transmission (8AT); and a next-generation Toyota Hybrid System (THS II).
 
TNGA-Inspired 2.5-Liter 4-Cylinder Dynamic Force Engine
Providing high power output with smooth and highly refined operation, the Camry’s new 2.5-liter four-cylinder Dynamic Force Engine has outstanding combustion efficiency. This new powerplant incorporates an array of Toyota’s most advanced technologies including Dual VVT-i with VVT-iE (Variable Valve Timing intelligent system by Electric motor), D-4S (Direct injection 4-stroke gasoline engine Superior version) direct injection and laser-clad valve seats for optimal power production, emissions performance and fuel efficiency.  With its long-stroke and high compression ratio, multi-hole direct fuel injectors, variable cooling system and VVT-iE, this high-output powerplant takes the gasoline-powered internal combustion engine to an increased level of thermal efficiency.

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 innovative Dual VVT-i with VVT-iE variable valve timing system uses an electric motor instead of oil pressure to control variable valve timing, helping the system enhance fuel efficiency with cleaner exhaust emissions—even when operating in cold temperatures or at low RPMs.

Utilizing a combination of both higher-pressure direct fuel injection (DI) and lower-pressure port fuel injection (PFI) - - controlling the appropriate fuel injection method in accordance with certain driving/operational conditions - - and new multi-hole (six per injector) nozzle direct injectors further elevate both fuel economy and power production.

Other important new technological innovations for the 2.5-liter 4-cylinder Dynamic Force Engine include a variable cooling system, full variable oil pump and a cooled Exhaust Gas Recirculation (EGR) system.
