Diesels have poor accelleration?
Diesel engines tend to be heavy per horsepower, even in “lightweight” auto applications. That alone limits the power/weight ratio of the car. In addition, engines tend to get substituted on a pound-for-pound basis in order to avoid redesigning the front end of the car, so that further limits the peak engine power and thus power/weight ratio. With diesel cars is when you want to go you floor it and leave it there for a while. Essentially all heavy vehicles are diesel, rather than gasoline, and essentially all heavy vehicles have low power-to-weight ratios compared to cars. Brakes? Almost all heavy vehicles have air brakes, while lighter vehicles usually have hydraulic brakes. Air brakes operate using an air pressure regulator at your foot, and air-filled pistons at the wheels. The harder you push on the pedal, the higher the pressure in the air lines, the wheel cylinders, and the stronger the brake application. All systems can fail; brakes are especially critical because if the brakes f
