The 4 Series Gran Coupe’s corrosion warranty is 6 years longer than the CTS’ (12 vs. 6 years).

Regenerative brakes improve the 4 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The CTS doesn’t offer a regenerative braking system.

Regardless of its engine, the 4 Series Gran Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CTS V-Sport doesn’t offer an automatic engine start/stop system.

Tires and Wheels

For better ride, handling and brake cooling the 4 Series Gran Coupe has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CTS.

Suspension and Handling

The 430i Gran Coupe handles at .89 G’s, while the CTS Premium pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The 4 Series Gran Coupe is 1 foot shorter than the CTS, making the 4 Series Gran Coupe easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver, the interior of the 430i Gran Coupe xDrive is quieter than the CTS V-Sport Premium Luxury:

Cargo Capacity

The 4 Series Gran Coupe has a larger trunk with its rear seat up than the CTS (17 vs. 13.7 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the 4 Series Gran Coupe’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The CTS doesn’t offer a power or hands-free opening trunk.

Ergonomics

The 4 Series Gran Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The CTS’ standard manually variable intermittent wipers have to be constantly adjusted.

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 Gran Coupe offers available headlight washers to keep headlight output high. The CTS doesn’t offer headlight washers.

Model Availability

The BMW 4 Series comes in coupe, convertible and four door hatchback bodystyles; the Cadillac CTS isn’t available as a coupe or convertible.

Economic Advantages

Insurance will cost less for the 4 Series Gran Coupe owner. The Car Book by Jack Gillis rates the 4 Series Gran Coupe with a number “1” insurance rate while the CTS is rated higher at a number “10” rate.

The 4 Series Gran Coupe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the 4 Series Gran Coupe will retain 44.99% to 47.5% of its original price after five years, while the CTS only retains 37.28% to 38.81%.

According to The Car Book by Jack Gillis, the 4 Series Gran Coupe is less expensive to operate than the CTS because it costs $234 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the 4 Series Gran Coupe than the CTS, including $399 less for a muffler, $28 less for front brake pads, $23 less for fuel injection, $411 less for a fuel pump and $33 less for front struts.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW 4 Series Gran Coupe will be $6901 to $21599 less than for the Cadillac CTS.

Recommendations

J.D. Power and Associates rated the 4 Series Gran Coupe third among compact premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The CTS isn’t in the top three.

The BMW 4 Series outsold the Cadillac CTS by almost four to one during 2017.
