The text states that, in a normal car, a lot of work goes into making the engine work quietly and last a long time. However for a race car’s engine, the focus is on
A) keeping the engine fuel efficient.
B) making the engine lightweight and powerful.
C) building an engine that is as heavy as possible.
D) designing an engine that can collapse in a crash.
The correct answer is B) making the engine lightweight and powerful.
In a race car, the primary focus is on maximizing performance, which includes creating an engine that has high power output while also being lightweight. This allows for better acceleration and speed, which are crucial for racing, rather than prioritizing quiet operation or fuel efficiency as in standard cars.
