What is the difference between models with 't' and without 't'?

[LaSara]

The differences between cars with 't' and without 't' are as follows: 1. Different engines: Cars with 't' are equipped with turbocharged or supercharged engines; cars without 't' are equipped with naturally aspirated engines. 2. Different power: With the same displacement, cars with 't' have stronger power than cars without 't', approximately 40% stronger. 3. Different maintenance costs: The repair and maintenance costs for cars with 't' are much higher than those for cars without 't'. 4. Different fuel consumption: For long-distance driving, cars with 't' are more fuel-efficient because the turbocharger intervenes, allowing fuel to burn more completely; for urban driving, cars without 't' are more fuel-efficient because it's difficult for vehicles to reach speeds where the turbocharger can intervene in city driving.
