Toyota Reveals New Family Of Downsized Turbo Engines

Citing carbon as the enemy, Toyota has vowed to continue developing the internal combustion engine; a stance it shares with two other Japanese automakers: Subaru and Mazda.

The three Japanese carmakers are doubling down on next-generation internal combustion as a key technology for cutting carbon, even as the auto industry increasingly goes electric. By developing cleaner, more compact power plants that can run on carbon neutral fuels and combine with hybrid systems, Toyota will breathe new life into the internal combustion engine.

The new engines will be smaller and more compact than current engines. The packaging will enable Toyota to use an EV platform as the starting point. From there, it’ll be re-engineered to fit either a hybrid or plug-in hybrid layout. As a result, the carmaker says, will be bolder designs with lower hood lines, roomier cabins, and airy greenhouses.

Among Toyota’s new engines is a 1.5-liter engine with a high thermal efficiency resulting in big fuel efficiency gains. This engine, to be outfitted in their smaller vehicles, have a 10 percent reduction in both volume and height compared to current 1.5-liter engines.

A turbocharged version of the same engine will replace the current 2.5-liter 4-cylinder. As a result, it has a 20 percent volume reduction and 15 percent height reduction. It will also have a 30 percent increase in fuel efficiency.

Also on tap is a 2.0-liter turbocharged engine generating much higher power than today's standard 2.4-liter turbo while delivering better fuel economy—up to 30 percent better.

Toyota did not give specific timelines on when the new engines will arrive, but they’re expected to be launched when the new emissions come effect as early as 2027.


  1. So basically its what manufacturers like Ford and Honda and other chinese cars are doing now?

  2. Maybe the engines should be 3 cylinder and not displacement

  3. To work as a motor generator like the Nissan Kicks e-Power?
