A car manufacturer notices that customers are increasingly buying its most fuel-efficient models. At the same time, its top two luxury models also make up significant sales. What might the marketing department recommend for the next year's line-up?

a. a larger luxury car
b. a fuel-efficient luxury car
c. a strict focus on fuel-efficient cars
d. a truck that will attract different customers

b. a fuel-efficient luxury car

The marketing department might recommend introducing a fuel-efficient luxury car for the next year's line-up. This is because the manufacturer has observed an increasing demand for fuel-efficient models, as well as significant sales in the luxury segment. By combining these two trends, the marketing department can capitalize on the customer preference for fuel efficiency while also targeting the luxury car market. This approach allows the manufacturer to cater to the changing preferences of its customers and potentially gain a competitive advantage in both segments.
