Which is More Fuel-Efficient, Cars with T or Without T?

[MacAna]

Cars with T naturally represent better fuel efficiency. Here are some measures to improve fuel efficiency: 1. Control RPM: While driving, the optimal engine RPM for most fuel-injected cars is around 2200–2500. Regardless of the gear, maintain the engine RPM within this range. Too low RPM will make the car sluggish, consume fuel without moving, and damage the engine; too high RPM increases unnecessary fuel consumption and also harms the engine. 2. Maintain Speed: The most fuel-efficient driving condition is maintaining a constant speed in a straight line. The most fuel-efficient speed for small-displacement cars is 60–80 km/h, while for medium-displacement cars, it is 80–100 km/h. Driving at the economic speed ensures the best fuel efficiency.
