For enhanced safety, the front seat shoulder belts of the Infiniti Q70 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 Sedan doesn’t offer height-adjustable seat belts.

The Q70 has standard Active Head Restraints (AHR), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the AHR system moves the headrests forward to prevent neck and spine injuries. The 5 Series Sedan doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The Q70 offers optional Backup Collision Intervention which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 5 Series Sedan doesn’t offer backup collision prevention brakes.

To help make backing safer, the Q70’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 5 Series Sedan doesn’t offer a cross-path warning system.

Both the Q70 and the 5 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems and blind spot warning systems.


The Q70 comes with a full 4-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The 5 Series Sedan’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the Q70 2 years and 20,000 miles longer than BMW covers the 5 Series Sedan. 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 Sedan ends after only 4 years or 50,000 miles.


A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Q70’s reliability 16 points higher than the 5 Series Sedan.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than BMW vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 7 more problems per 100 vehicles, BMW is ranked 8th.
