For enhanced safety, the front seat shoulder belts of the Cadillac CT5 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 5 Series doesn’t offer height-adjustable seat belts.

Both the CT5 and the 5 Series 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, driver alert monitors and available all wheel drive.

Cadillac’s powertrain warranty covers the CT5 2 years and 20,000 miles longer than BMW covers the 5 Series. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 5 Series 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’s warranty.

The battery on the CT5 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the CT5’s battery 20 to 30 degrees cooler, its life is increased by years. The 5 Series’ battery is in the hot engine compartment.

The CT5’s optional 3.0 turbo V6 produces 7 lbs.-ft. more torque (405 vs. 398) than the 540i xDrive’s standard 3.0 turbo 6-cylinder hybrid.

As tested in Car and Driver the Cadillac CT5 turbo V6 is faster than the 530i 2.0 turbo 4-cylinder hybrid:

An engine control system that can shut down some of the engine’s cylinders helps improve the CT5’s fuel efficiency. The 5 Series doesn’t offer a system that can shut down part of the engine.

The CT5 has 1.5 gallons more fuel capacity than the 5 Series (17.4 vs. 15.9 gallons), for longer range between fill-ups.

The CT5 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 5 Series doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Cadillac CT5, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 5 Series.

For better traction, the CT5’s optional tires are larger than the largest tires available on the 5 Series (255/35R20 vs. 245/40R20).

The CT5 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 5 Series doesn’t offer vehicle monitored tire inflation.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the CT5 can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The 5 Series doesn’t offer self-sealing tires.

For better maneuverability, the CT5’s turning circle is 1.4 feet tighter than the 5 Series’ (39 feet vs. 40.4 feet).

The Cadillac CT5 may be more efficient, handle and accelerate better because it weighs about 400 to 550 pounds less than the BMW 5 Series.

The CT5’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 5 Series 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 has standard extendable sun visors. The 5 Series doesn’t offer extendable visors.

The CT5 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the 5 Series.
