Tires and Wheels

For better ride, handling and brake cooling the i3 has standard 19-inch wheels. Only 18-inch wheels are available on the CT6 Plug-In. The i3 offers optional 20-inch wheels.

Suspension and Handling

For better maneuverability, the i3’s turning circle is 7.6 feet tighter than the CT6 Plug-In’s (32.4 feet vs. 40 feet). The i3s’ turning circle is 6.2 feet tighter than the CT6 Plug-In’s (33.8 feet vs. 40 feet).

Chassis

The BMW i3 may be more efficient, handle and accelerate better because it weighs about 1250 to 1600 pounds less than the Cadillac CT6 Plug-In.

The i3s is 3 feet, 10 inches shorter than the CT6 Plug-In, making the i3 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The i3’s standard rear seats fold to accommodate long and bulky cargo. The CT6 Plug-In doesn’t offer folding rear seats.

Ergonomics

The i3’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 CT6 Plug-In’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To improve rear visibility by keeping the rear window clear, the i3 has a standard rear wiper. The CT6 Plug-In doesn’t offer a rear wiper.

The CT6 Plug-In’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The i3’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

Recommendations

Consumer Reports® recommends the BMW i3, based on reliability, safety and performance.

J.D. Power and Associates rated the i3 third among small premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The CT6 Plug-In isn’t in the top three.
