Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 4 Series Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A5 doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the 4 Series Coupe’s wheelbase is 1.8 inches longer than on the A5 Coupe (110.6 inches vs. 108.8 inches).

The 430i Coupe handles at .90 G’s, while the A5 Prestige Coupe pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the 4 Series Coupe’s turning circle is .6 feet tighter than the A5’s (37.1 feet vs. 37.7 feet).

Chassis

The design of the BMW 4 Series Coupe amounts to more than styling. The 4 Series Coupe has an aerodynamic coefficient of drag of .29 Cd. That is lower than the A5 (.29 to .3). A more efficient exterior helps the 4 Series Coupe go faster and keeps the interior quieter. It also helps the 4 Series Coupe get better fuel mileage.

Passenger Space

The 4 Series Coupe has a much larger trunk than the A5 Coupe (15.7 vs. 11.6 cubic feet).

Ergonomics

If the windows are left open on the 4 Series Coupe w/Comfort Access the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the A5 can’t use the remote to operate the windows.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 4 Series Coupe offers available headlight washers to keep headlight output high. The A5 doesn’t offer headlight washers.

To help drivers see further while navigating curves, the 4 Series Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The A5 doesn’t offer cornering lights.

A power rear sunshade is optional in the 4 Series Coupe to help block heat and glare for the rear passengers. The A5 doesn’t offer a rear sunshade.

Model Availability

The 4 Series Coupe is available in both rear-wheel drive and all-wheel drive configurations. The A5 doesn’t offer a two-wheel drive configuration.

Economic Advantages
