Is the engine of a large truck (bus) the same as that of a regular sedan?

Not the same, big cars are all diesel engines that focus on torque, with a maximum displacement of over ten liters. Generally, the horsepower of buses is not high, with few exceeding 200 horsepower (Volkswagen 2.0T has a minimum of 180 horsepower and a maximum of 300 horsepower), but the torque is close to or exceeds 1000Nm. Due to the need to drive at high speeds, the trailer head has a higher horsepower. In Europe, it is generally considered very high if it exceeds 400 horsepower. In rare cases, a few abnormal models can be equipped with 600 horsepower, with a torque exceeding 2000Nm. It's not suitable for a sports car. Firstly, it's too big and heavy to fit, and secondly, the horsepower is not very high, which is not worth it. Diesel engines are not specifically designed for horsepower. Now the entry-level supercar Ferrari has 458 570 horsepower and the Lamborghini Huracan has 610 horsepower, both surpassing the vast majority of large cars.
