Final answer:
The correct answer is option c) gear ratios. Auxiliary sections are used to multiply the number of available gear ratios from a transmission.
Step-by-step explanation:
The correct answer is option c) gear ratios. Auxiliary sections are used to multiply the number of available gear ratios from a transmission. Transmission technologies like 7+ speeds, dual clutch transmissions (DCTs), and continuously variable transmissions (CVTs) improve fuel economy and reduce CO₂ emissions.
The correct answer is option c) gear ratios. Auxiliary sections are used to multiply the number of available gear ratios from a transmission. This allows for better performance and efficiency in vehicles.
Modern transmission technologies like 7+ speeds, dual clutch transmissions (DCTs), and continuously variable transmissions (CVTs) significantly improve fuel economy and reduce CO₂ emissions as they allow the engine to operate more efficiently by staying within the optimal power range.
These advancements in transmission technology have led to transmissions that are capable of more gear ratios, which provides smoother acceleration, better fuel efficiency, and overall improved vehicle performance.
This is vital as vehicles must meet stricter fuel economy and emissions regulations.
