Which of the following effects is associated with an axle ratio between 3.0 and 3.4?

An axle ratio between 3.0 and 3.4 typically indicates a balance in performance characteristics, particularly related to acceleration and fuel economy. This range is often suited for vehicles that need a compromise between power delivery and efficiency.

When the axle ratio is on the lower side, such as within the 3.0 to 3.4 range, it’s designed for improved fuel economy because it allows the engine to operate at lower RPMs during highway cruising speeds. This results in a more efficient use of fuel. However, this can also lead to more sluggish acceleration since the vehicle isn’t geared for aggressive power delivery. The tradeoff here is that while fuel economy improves, the vehicle might not feel as responsive during initial acceleration when compared to higher axle ratios, which are typically tuned for higher performance and quicker starts.

Thus, the chosen answer reflects the typical characteristics of vehicles within this axle ratio range, presenting a realistic expectation of vehicle performance in everyday use.
