If you want a turbocharged Toyota, get a Lexus.
The general trend in automotive powertrains is to reduce the displacement and add forced induction, such as a turbocharger. Toyota doesn’t see a necessity in following this tendency for all of its products. While Lexus models are now packing turbos, the Toyota brand intends to maximize the efficiency of naturally-aspirated powerplants for vehicles in the United States and Canada.
Ben Schlimme, Toyota Motor North America’s powertrain boss, said during the CAR Management Briefing Seminars that the company would apply the tech from the new 2.5-litre four-cylinder in the 2018 Camry to other engines, according to Automotive News.
Toyota refers to the mill as the Dynamic Force engine. While it displaces the same 2.5 litres as the 2017 Camry, the new powerplant makes 201 horsepower and 184 pound-feet of torque in standard form, and 206 hp and 186 lb-ft of torque in the XSE trim. It’s an increase of 25 hp and 14 lb-ft of torque from last year. An eight-speed automatic routes power to the front wheels rather than the earlier six speed. Fuel economy sees a major boost to 8.4 litres per 100 kilometres city, 6.0 L/100 km highway, and 7.3 L/100 km combined versus 9.8/7.8/8.6 L/100 km respectively from last year’s four cylinder.
The gains come from the use of both direct and port fuel injection. Plus, a revised intake layout swirls the air as it enters the cylinder, which results in more power and lower emissions, according to Automotive News.
“Dynamic Force is not solely aimed at the 2.5-litre engine,” Schlimme said, according to Automotive News. “We are working to bring it to other segments.” In addition, V6 and V8 versions are under development.
Sticking with naturally aspirated engines makes the Camry an outlier in its class. Turbocharged mills are available or even standard on vehicles like the Honda Accord, Ford Fusion, Chevrolet Malibu, and Volkswagen Passat. The Subaru Legacy, Nissan Altima, and Dodge Charger aren’t moving to forced induction quite yet, though.
