Safety

The G80’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 3 Series Sedan doesn’t offer pre-crash pretensioners.

The G80’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 3 Series Sedan doesn’t offer a driver alert monitor.

Both the G80 and the 3 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, available all wheel drive and rear parking sensors.

The Genesis G80 weighs 431 to 1134 pounds more than the BMW 3 Series Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 36 vehicles tested by the IIHS. The 3 Series Sedan has not been tested, yet.

Warranty

The G80 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The 3 Series Sedan’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G80 6 years and 50,000 miles longer than BMW covers the 3 Series Sedan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the 3 Series Sedan ends after only 4 years or 50,000 miles.
