The BMW 3 Series Sedan has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G80 doesn’t offer a front passenger side knee airbag.

The 3 Series Sedan has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Compared to metal, the 3 Series Sedan’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the 3 Series Sedan and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the BMW 3 Series Sedan is safer than the Genesis G80:

	3 Series Sedan	G80
	Driver
STARS	5 Stars	4 Stars
HIC	145	202
Neck Injury Risk	23%	28%
Neck Stress	207 lbs.	227 lbs.
Leg Forces (l/r)	201/230 lbs.	296/772 lbs.
	Passenger
STARS	5 Stars	5 Stars
Chest Compression	.6 inches	.7 inches
Neck Injury Risk	33%	34%
Neck Stress	170 lbs.	238 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the BMW 3 Series Sedan is safer than the Genesis G80:

	3 Series Sedan	G80
	Front Seat
STARS	5 Stars	5 Stars
Hip Force	252 lbs.	290 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	13 inches	13 inches
Hip Force	544 lbs.	676 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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 3 Series Sedan its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 122 vehicles tested by the IIHS. The G80 is only a standard “Top Safety Pick” for 2019.

Warranty

The 3 Series Sedan’s corrosion warranty is 5 years longer than the G80’s (12 vs. 7 years).

There are over 14 percent more BMW dealers than there are Genesis dealers, which makes it easier should you ever need service under the 3 Series Sedan’s warranty.

Reliability

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 3 Series Sedan’s reliability 28 points higher than the G80.

Engine

The M340i’s standard 3.0 turbo 6-cylinder hybrid produces 7 more horsepower (382 vs. 375) than the G80’s optional 3.5 turbo V6.

As tested in Car and Driver the 330i 2.0 turbo 4-cylinder is faster than the Genesis G80 turbo 4 cyl.:

	3 Series Sedan	G80
Zero to 60 MPH	5.1 sec	5.7 sec
Zero to 100 MPH	13.8 sec	14.1 sec
5 to 60 MPH Rolling Start	6.5 sec	6.6 sec
Passing 30 to 50 MPH	3.2 sec	3.4 sec
Passing 50 to 70 MPH	3.9 sec	4.3 sec
Quarter Mile	13.8 sec	14.1 sec
Top Speed	155 MPH	145 MPH

As tested in Motor Trend the M340i 3.0 turbo 6-cylinder hybrid is faster than the Genesis G80 3.5:

	3 Series Sedan	G80
Zero to 60 MPH	4.2 sec	5.2 sec
Quarter Mile	12.7 sec	13.7 sec
Speed in 1/4 Mile	110.4 MPH	103.8 MPH

Fuel Economy and Range

On the EPA test cycle the 3 Series Sedan gets better mileage than the G80:

			MPG
3 Series Sedan
	RWD	2.0 turbo 4-cyl.	25 city/34 hwy
	AWD	2.0 turbo 4-cyl.	24 city/33 hwy
		3.0 turbo 6-cyl. Hybrid	23 city/32 hwy
G80
	RWD	2.5 turbo 4-cyl.	23 city/32 hwy
	AWD	2.5 turbo 4-cyl.	22 city/30 hwy
		3.5 turbo V6	17 city/26 hwy

Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

Brakes and Stopping

The 3 Series Sedan’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 2.5T are solid, not vented.

The 3 Series Sedan stops much shorter than the G80:

	3 Series Sedan	G80
70 to 0 MPH	151 feet	174 feet	Car and Driver
60 to 0 MPH	103 feet	124 feet	Motor Trend

Tires and Wheels

The 330i’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 G80’s standard 50 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 3 Series Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G80 doesn’t offer run-flat tires.

Suspension and Handling

The 330i handles at .99 G’s, while the G80 pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

The M340i executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the G80 AWD (25 seconds @ .77 average G’s vs. 26.2 seconds @ .68 average G’s).

Chassis

The BMW 3 Series Sedan may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Genesis G80.

The 3 Series Sedan is 10.8 inches shorter than the G80, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.

The front grille of the 3 Series Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The G80 doesn’t offer active grille shutters.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the 3 Series Sedan easier. The 3 Series Sedan’s trunk lift-over height is 26.7 inches, while the G80’s liftover is 28.8 inches.

The 3 Series Sedan’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Genesis. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 30% lower rating, Genesis is ranked 23rd.

Ergonomics

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 3 Series Sedan’s available headlights were rated “Good” by the IIHS, while the G80’s headlights are rated “Acceptable.”

To help drivers avoid possible obstacles, the 3 Series Sedan has standard cornering lights to illuminate around corners when the turn signals are activated. The G80 doesn’t offer cornering lights. The 3 Series Sedan also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Economic Advantages

The 3 Series Sedan will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the 3 Series Sedan will retain 44.47% to 45.8% of its original price after five years, while the G80 only retains 43.88% to 43.95%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW 3 Series Sedan will be $5597 to $7473 less than for the Genesis G80.

Recommendations

Consumer Reports® recommends the BMW 3 Series Sedan, based on reliability, safety and performance. The Genesis G80 isn't recommended.

The BMW 3 Series outsold the Genesis G80 by over 9 to one during the 2021 model year.
