Compare the2023 BMW 2 SeriesVS 2022 Cadillac CT4-V

The 2 Series has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CT4-V doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The 2 Series’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CT4-V doesn’t offer a driver alert monitor.

Both the 2 Series and the CT4-V have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

The 2 Series’ corrosion warranty is 6 years longer than the CT4-V’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the 2 Series for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Cadillac only pays for the first scheduled maintenance visit on the CT4-V.

J.D. Power and Associates rated the 2 Series first among small premium cars in their 2022 Initial Quality Study. The CT4-V isn’t in the top three in its category.

Regardless of its engine, the 2 Series’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CT4-V Blackwing doesn’t offer an automatic engine start/stop system.

For better stopping power the 2 Series’ standard brake rotors are larger than those on the CT4-V:

The 2 Series stops shorter than the CT4-V:

For better traction, the M240i Coupe’s optional front tires are larger than the largest tires available on the CT4-V (245/35R19 vs. 235/35R18).

For better handling and stability, the average track (width between the wheels) on the 2 Series is 1.9 inches wider in the front and 1.7 inches wider in the rear than the average track on the CT4-V.

The M240i Coupe xDrive handles at .98 G’s, while the CT4-V pulls only .93 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 230i’s turning circle is .7 feet tighter than the CT4-V’s (36.4 feet vs. 37.1 feet). The M240i’s turning circle is .6 feet tighter than the CT4-V Blackwing’s (38.2 feet vs. 38.8 feet).

The 230i is 8.2 inches shorter than the CT4-V, making the 2 Series easier to handle, maneuver and park in tight spaces.

The front grille of the 2 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The CT4-V doesn’t offer active grille shutters.

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the 2 Series offers cargo security. The CT4-V’s non-lockable folding seat defeats cargo security.

If the front windows are left open on the 2 Series w/Comfort Access the driver can close them 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 CT4-V can only close the windows from inside the vehicle, with the ignition on.

The CT4-V’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The 2 Series’ optional 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.

The 2 Series’ optional Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The CT4-V doesn’t offer an automated parking system.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW 2 Series will be $17915 to $25202 less than for the Cadillac CT4-V.
