This improved the aerodynamic performance of the car.

The improvements would have little impact on overall vehicle shape or aerodynamic performance.

"There has been very little improvement in the aerodynamic performance of golf balls in the last 8, 9, 10 years."

So for 1987, the body shell and interior were altered for improved aerodynamic performance.

More recent design techniques allow for stealthy designs such as the F-22 without compromising aerodynamic performance.

All of these changes were carried out with the aim of improving each car's aerodynamic performance.

Any specific part of the car influencing its aerodynamic performance:

The front and rear bumpers were reshaped for improved aerodynamic performance.

This also improves aerodynamic performance and increases the payload which can be carried.

The above result in a 4% improvement in aerodynamic performance.
