The G70’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 Q50 doesn’t offer a driver alert monitor.

Both the G70 and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive and around view monitors.

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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G70 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The Q50 has not been fully tested, yet.

The G70’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q50’s standard 55 series tires.

For better ride, handling and brake cooling the G70 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Q50.

The G70 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 Q50; 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.

The G70’s front to rear weight distribution is more even (51% to 49%) than the Q50’s (55.8% to 44.2%). This gives the G70 more stable handling and braking.

The G70 handles at .95 G’s, while the Q50 Red Sport 400 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The G70’s headlights were rated “Good” by the IIHS, while the Q50’s headlights are rated “Acceptable” to “Marginal.”

Both the G70 and the Q50 offer available heated front seats. The G70 Prestige/Sport also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q50.

Standard air-conditioned seats in the G70 3.3T/2.0T Manual/Prestige/Sport keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q50 doesn’t offer air-conditioned seats.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Genesis G70 3.3T Elite/Prestige/Sport has a standard wireless phone charging system (Qi) in the center console. The Q50 doesn’t offer wireless personal charging.
