Compare the2025 Cadillac CT5-VVS 2025 BMW M5

For enhanced safety, the front seat shoulder belts of the Cadillac CT5-V are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M5 doesn’t offer height-adjustable seat belts.

Both the CT5-V and M5 have rear cross-traffic warning, but the CT5-V (except Manual) has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The M5’s Cross Traffic Warning doesn’t automatically brake.

Both the CT5-V and the M5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 driver alert monitors.

Cadillac’s powertrain warranty covers the CT5-V 2 years and 20,000 miles longer than BMW covers the M5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the M5 ends after only 4 years or 50,000 miles.

There are over 62 percent more Cadillac dealers than there are BMW dealers, which makes it much easier should you ever need service under the CT5-V’s warranty.

An engine control system that can shut down some of the engine’s cylinders helps improve the CT5-V Blackwing’s fuel efficiency. The M5 doesn’t offer a system that can shut down part of the engine.

The CT5-V has 1.6 gallons more fuel capacity than the M5 (17.5 vs. 15.9 gallons), for longer range between fill-ups.

The CT5-V has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The M5 doesn’t offer a cap-less fueling system.

The CT5-V offers a manual transmission for better acceleration, control and sportiness. The M5 doesn’t offer a manual transmission.

A 10-speed automatic is standard on the Cadillac CT5-V, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the M5.

The CT5-V stops shorter than the M5:

The CT5-V Blackwing’s 275/35R19 front and 305/30R19 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the M5’s 40 series front and 35 series rear tires.

The CT5-V has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The M5 doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CT5-V can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The M5 doesn’t offer run-flat tires.

The CT5-V Blackwing handles at 1.02 G’s, while the M5 Sedan pulls only .98 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the CT5-V’s turning circle is 2.3 feet tighter than the M5’s (39 feet vs. 41.3 feet).

The Cadillac CT5-V may be more efficient, handle and accelerate better because it weighs about 1250 to 1350 pounds less than the BMW M5.

The CT5-V is 6.8 inches shorter than the M5, making the CT5-V easier to handle, maneuver and park in tight spaces.

The CT5-V has 1.1 inches more front legroom and 1.7 inches more rear legroom than the M5.

The CT5-V’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The M5 does not have an oil pressure gauge.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the CT5-V has standard extendable sun visors. The M5 doesn’t offer extendable visors.

The CT5-V is available in both rear-wheel drive and all-wheel drive configurations. The M5 doesn’t offer a two-wheel drive configuration.

Consumer Reports® recommends the Cadillac CT5-V, based on reliability, safety and performance.
