What displacement is equivalent to a 1.3t engine?
1 Answers
A 1.3t engine is essentially a 1.3L naturally aspirated engine equipped with a turbocharger to enhance its power output and torque. Therefore, the actual displacement remains 1.3L, but in terms of power, a 1.3t engine is comparable to a 1.8L naturally aspirated engine. Different manufacturers have varying engine tuning approaches, but generally, a turbocharged engine of the same displacement delivers about 40% more power than a naturally aspirated one. In Western countries, the displacement of a turbocharged engine is often calculated by multiplying its actual displacement by 1.4. However, in China, only the direct numerical value is considered—both 1.3t and 1.3L engines are taxed based on the 1.3L displacement for vehicle purchase. Turbocharging not only provides stronger power than natural aspiration but also improves fuel efficiency, which is why many automakers have introduced small-displacement turbocharged engines. Generally, a larger displacement results in higher power output, but it also leads to higher fuel consumption. This is why off-road vehicles and sports cars typically have larger displacements. Smaller-displacement cars, on the other hand, offer more modest performance but better fuel economy. However, even with a small displacement, proper turbocharger tuning can enable these engines to outperform larger naturally aspirated engines in terms of power output.
