Compare the2024 BMW 2 Series Gran CoupeVS 2023 Cadillac CT4-V

The 2 Series Gran Coupe 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 Gran Coupe’s 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 Gran Coupe 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 and available all wheel drive.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the 2 Series Gran Coupe the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS.

The 2 Series Gran Coupe has a standard space-saver spare (not available on M235i) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the CT4-V; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the CT4-V don’t have a run-flat feature, either.

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

To make loading groceries and cargo easier when your hands are full, the 2 Series Gran Coupe’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The CT4-V doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The 2 Series Gran Coupe’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car.

If the windows are left open on the 2 Series Gran Coupe the driver can close them all at the outside door handle or from a distance using the remote. 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.
