Toyota isn’t relying on turbochargers to boost fuel efficiency, instead focusing on its “Dynamic Force” engine tech.
Most automakers are turning to smaller, turbocharged four-cylinder engines to balance fuel economy and performance, but Toyota has no plans of doing the same. The Japanese automaker is instead finding ways to improve fuel efficiency while cutting emissions and increasing performance without having to turn to forced induction. Under the hood of the new Camry is a 2.5-liter four-cylinder engine called Dynamic Force, which offers 206 horsepower while returning up to 41 mpg on the highway.
Unlike other automakers’ new engines, Toyota didn’t downsize the Camry’s engine, but rather engineers worked to improve engine efficiency through four main areas: friction reduction, exhaust flow, cooling, and in the intake system. The result is an increase of thermal efficiency to 40 percent, something few engines ever reach.
Speaking at the CAR Management Briefing Seminars, Toyota Motor North America’s powertrain executive program manager for advanced planning and research, Ben Schlimme confirmed Dynamic Force isn’t just reserved for the 2.5-liter engine. The company is working on bringing it to other segments, adding Dynamic Force for V6 and V8 engines are currently in “concept” form.
That means Toyota’s trucks and SUVs will likely benefit from the technology, but that also means Toyota won’t be using turbochargers anytime soon. We are of course, hoping the upcoming Supra successor will be an exception.
