While European automakers have gone the engine downsizing and forced induction route for an entire generation of cars now, Asian automakers such as Toyota, Honda and Mazda have not fully embraced the idea yet.

The only Asian carmaker that has announced a small displacement downsized engine that I can remember in the past year is Nissan with their MR16DDT 1.6 litre and H4Jt 1.4 litre inline-4 turbocharged engines, and i suspect even that is because of Renault influence. Honda dabbled with a turbocharged 2.3 litre i-VTEC turbo 4-potter for the US market but they’ve not announced a new internal combustion engine in a very long time, which is a little disappointing for a car company who used to be known for their engines. Their last major announcement was AVTEC and then nothing!

But with the latest round of Euro emission standards coming around we are starting to see this change as Toyota have just announced that it intends to increase the Toyota fleet’s fuel efficiency via turbochargers and direct fuel injection in smaller vehicles. According to Toyota executive vice president in charge of R&D Takeshi Uchiyamada, turbochargers and direct injection will soon be a regular feature in the entire Toyota line-up, including bread and butter models like the Corolla and the Camry.

The new 1.33 litre 1NR-FE featured in cars like the Euro market Auris, Yaris, iQ could be a prime candidate to receive this technology. It’s Toyota’s newest 4 cylinder engine family and features Dual VVT-i and auto start-stop technology. The high compression ratio of 11.5:1 would have to be brought down to something like 9.5:1 to 10.5:1 of course.

From the normally aspirated 101hp and 132Nm at a lowish 3,800rpm, we could see it brought up to something like 130hp-150hp and 180Nm-200Nm to replace the bigger engines in the Corolla.
