What is the equivalent displacement of Toyota's 1.2T engine?

[AdelineRose]

Toyota's 1.2T is equivalent to a 1.6L displacement. According to relevant tests, Toyota's 1.2T turbocharged engine can achieve the power output of a 1.6L naturally aspirated engine. Here are some details about Toyota's 1.2T: Exterior: The Corolla's body dimensions have significantly increased compared to the previous generation Corolla, presenting an unprecedented 'wide and low' stance while creating a spacious interior. Performance: Toyota's 1.2T engine features early turbocharger engagement, resulting in lower fuel consumption. After the turbocharger engages, it delivers power equivalent to approximately a 1.7L naturally aspirated engine. The newly developed 1.6L and 1.8L engines with Dual VVT-i technology offer an even more powerful driving experience.

I've been driving the Corolla 1.2T for almost three years now, and the engine feels quite similar to a 1.6L naturally aspirated one in daily use. It does feel a bit sluggish at initial acceleration, but once the turbo kicks in at 1800 rpm, overtaking becomes quite effortless. Last time I drove on mountain roads with four passengers, climbing hills in third gear didn't feel strenuous at all. The fuel consumption is truly economical, with just over 7L/100km in city driving with AC on. For those concerned about power, the actual driving experience feels much stronger than the paper 1.2L displacement suggests, especially the mid-range acceleration, which is comparable to the old Nissan Sylphy 1.8L.

This question often comes up during car repairs. Don't let the small numbers fool you - Toyota's 1.2T 9NR engine packs some clever engineering with its direct injection and small turbo. Its maximum torque of 185 Nm already matches some naturally aspirated 1.8L engines. Recently when changing spark plugs on a Levin, I specifically checked the combustion chamber carbon buildup - it was cleaner than some 2.0L engines. However, turbocharged engines require more frequent maintenance - it's best to clean the throttle body every 50,000 km, otherwise you might feel sluggish throttle response at low RPMs. This engine is truly durable - I've seen ride-hailing vehicles clock over 300,000 km without major repairs.

Displacement conversion primarily depends on power and torque. The Toyota 1.2T delivers 116 horsepower with a peak torque of 185N·m, outperforming its predecessor, the 1.6L (122 horsepower/154N·m), in torque. During actual driving, the turbo kicks in at 1500 rpm, providing acceleration equivalent to a 1.8L naturally aspirated engine within 80km/h. However, high-speed acceleration is slightly weaker due to the smaller base displacement. The current Corolla achieves a 0-100km/h time of around 11 seconds in tests, close to the performance of the Civic 1.8L. It requires 0W-20 full synthetic oil, as thicker oil can affect turbo responsiveness.
