Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi A4 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 Genesis G70 doesn’t offer pretensioners for the rear seat belts.

The A4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The G70 doesn’t offer pre-crash pretensioners.

The A4 has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G70 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.

Both the A4 and the G70 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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 lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the A4 the rating of “Top Pick” for 2018, a rating granted to only 85 vehicles tested by the IIHS. The G70 has not been tested, yet.

Warranty

The A4’s corrosion warranty is 5 years longer than the G70’s (12 vs. 7 years).

Reliability

The Audi A4’s engines use a cast iron block for durability, while the G70’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Audi 5 places higher in reliability than Genesis.

Regardless of its engine, the A4’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Genesis only offers an automatic engine start/stop system on the G70 2.0T Automatic.

Transmission

The A4 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The G70 doesn’t offer an SMG.

Brakes and Stopping

The A4 stops shorter than the G70:

Tires and Wheels

For better traction, the A4’s optional tires are larger than the largest tires available on the G70 (245/40R18 vs. 225/40R19).

The A4’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the G70 3.3T/Dynamic/Sport’s 40 series front tires.

Suspension and Handling

The A4 has standard front and rear gas-charged shocks for better control over choppy roads. The G70’s suspension doesn’t offer rear gas-charged shocks.

The A4 Premium Plus Quattro handles at .92 G’s, while the G70 Sport pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The A4 Premium Plus Quattro executes Motor Trend’s “Figure Eight” maneuver quicker than the G70 Sport (25.3 seconds @ .74 average G’s vs. 26 seconds @ .68 average G’s).

Chassis

As tested by Car and Driver, the interior of the A4 Prestige Quattro is quieter than the G70 Dynamic:

Passenger Space

The A4 has .5 inches more rear headroom and .9 inches more rear legroom than the G70.

Cargo Capacity

The A4 has a much larger trunk than the G70 (13 vs. 10.5 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the A4 offers cargo security. The G70’s non-lockable folding seat and non-lockable remote release defeat cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the A4 has a standard power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The G70 doesn’t offer a power trunk.

Ergonomics

If the windows are left open on the A4 the driver can close them all at the outside door handle. The driver of the G70 can only operate the windows from inside the vehicle, with the ignition on.

The A4’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The G70’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G70 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A4 has standard headlight washers to keep headlight output high. The G70 doesn’t offer headlight washers.

Recommendations

Consumer Reports® chose the Audi A4 as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.
