- Radial tyres (I), streamlined body (II), and multipoint fuel injection (III) all contribute to improved fuel efficiency. - Catalytic converters (IV) are for emission control and do not improve fuel efficiency. - Option B includes II and III, two significant features for fuel efficiency in newer cars.
Consider the following features of newer models of motor cars: I. Radial tyres II. Streamlined body III. Multipoint fuel injection IV. Catalytic converter with exhaust Which of these features make the newer models of motor cars more fuel efficient?
