Safety

For enhanced safety, the front and rear seat shoulder belts of the Genesis G90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 6 Series Gran Turismo doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Genesis G90 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 6 Series Gran Turismo doesn’t offer height-adjustable seat belts.

Both the G90 and the 6 Series Gran Turismo have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G90 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The 6 Series Gran Turismo has not been tested, yet.

Warranty

The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The 6 Series Gran Turismo’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 6 years and 50,000 miles longer than BMW covers the 6 Series Gran Turismo. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the 6 Series Gran Turismo ends after only 4 years or 50,000 miles.

Reliability

To reliably start during all conditions and help handle large electrical loads, the G90 has a standard 950-amp battery. The 6 Series Gran Turismo’s 900-amp battery isn’t as powerful.

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The 6 Series Gran Turismo isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 19 more problems per 100 vehicles, BMW is ranked 11th.

Engine

The G90 3.3T’s standard 3.3 turbo V6 produces 30 more horsepower (365 vs. 335) and 46 lbs.-ft. more torque (376 vs. 330) than the 6 Series Gran Turismo’s 3.0 turbo 6 cyl. The G90 5.0’s standard 5.0 DOHC V8 produces 85 more horsepower (420 vs. 335) and 53 lbs.-ft. more torque (383 vs. 330) than the 6 Series Gran Turismo’s 3.0 turbo 6 cyl.

Fuel Economy and Range

The G90 has 3.9 gallons more fuel capacity than the 6 Series Gran Turismo (21.9 vs. 18 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the G90’s front brake rotors are larger than those on the 6 Series Gran Turismo:

14.2 inches

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the 6 Series Gran Turismo (275/40R19 vs. 245/45R19).

The G90’s 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 6 Series Gran Turismo’s standard 45 series tires.

The G90 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 6 Series Gran Turismo; 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.

Suspension and Handling

For a smoother ride and more stable handling, the G90’s wheelbase is 3.5 inches longer than on the 6 Series Gran Turismo (124.4 inches vs. 120.9 inches).

For better handling and stability, the track (width between the wheels) on the G90 is 1.3 inches wider in the front than on the 6 Series Gran Turismo.

For better maneuverability, the G90’s turning circle is 1.8 feet tighter than the 6 Series Gran Turismo’s (39.2 feet vs. 41 feet).

Chassis

The design of the Genesis G90 amounts to more than styling. The G90 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the 6 Series Gran Turismo (.29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G90 get better fuel mileage.

Passenger Space

The G90 has 1.7 inches more front headroom, 5.2 inches more front legroom and .8 inches more rear shoulder room than the 6 Series Gran Turismo.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the G90 offers cargo security. The 6 Series Gran Turismo’s hatchback body style defeats cargo security.

Ergonomics

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the G90 has standard extendable sun visors. The 6 Series Gran Turismo doesn’t offer extendable visors.

A power rear sunshade is standard in the G90 to help block heat and glare for the rear passengers. The 6 Series Gran Turismo doesn’t offer a rear sunshade.

The G90 has standard front air-conditioned seats and the G90 5.0 also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The 6 Series Gran Turismo doesn’t offer air-conditioned seats in the rear.

The G90 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 6 Series Gran Turismo.

Model Availability

The G90 is available in both rear-wheel drive and all-wheel drive configurations. The 6 Series Gran Turismo doesn’t offer a two-wheel drive configuration.
