Safety

To help make backing safer, the G70’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A-Class doesn’t offer a cross-path warning system.

Both the G70 and the A-Class 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 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 36 vehicles tested by the IIHS. The A-Class has not been tested, yet.

Warranty

The G70 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The A-Class’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G70 6 years and 50,000 miles longer than Mercedes covers the A-Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A-Class ends after only 4 years or 50,000 miles.

The G70’s corrosion warranty is 2 years longer than the A-Class’ (7 vs. 5 years).

Genesis pays for scheduled maintenance on the G70 for 3 years and 36,000 miles. Genesis will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the A-Class.

Reliability

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 Mercedes vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 24 more problems per 100 vehicles, Mercedes is ranked 14th.

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

Engine

The G70 2.0T’s standard 2.0 turbo 4 cyl. produces 64 more horsepower (252 vs. 188) and 39 lbs.-ft. more torque (260 vs. 221) than the A-Class’ 2.0 turbo 4 cyl. The G70 2.0T Sport’s optional 2.0 turbo 4 cyl. produces 67 more horsepower (255 vs. 188) and 39 lbs.-ft. more torque (260 vs. 221) than the A-Class’ 2.0 turbo 4 cyl. The G70 3.3T’s standard 3.3 turbo V6 produces 177 more horsepower (365 vs. 188) and 155 lbs.-ft. more torque (376 vs. 221) than the A-Class’ 2.0 turbo 4 cyl.

As tested in Car and Driver the G70 3.3T is faster than the Mercedes A 220 (automatics tested):

Fuel Economy and Range

The G70 has 2.3 gallons more fuel capacity than the A-Class (15.8 vs. 13.5 gallons), for longer range between fill-ups.

Transmission

An eight-speed automatic is standard on the Genesis G70, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A-Class.

The G70’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The A-Class doesn’t offer launch control.

Brakes and Stopping

For better stopping power the G70 3.3T/6-speed’s brake rotors are larger than those on the A-Class:

A-Class

Front Rotors

13.8 inches

12.6 inches

Rear Rotors

13.4 inches

11.6 inches

The G70’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the A-Class are solid, not vented.

Tires and Wheels

For better traction, the G70 has larger standard tires than the A-Class (225/45R18 vs. 205/55R17). The G70 3.3T/Dynamic/Sport’s tires are larger than the largest tires available on the A-Class (F:225/40R19 & R:255/35R19 vs. 205/55R17).

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 A-Class’ standard 55 series tires. The G70 3.3T/Dynamic/Sport’s 225/40R19 front and 255/35R19 rear tires have a lower 40 series front and 35 series rear profile than the A-Class’ 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 A-Class.

Suspension and Handling

For a smoother ride and more stable handling, the G70’s wheelbase is 4.2 inches longer than on the A-Class (111.6 inches vs. 107.4 inches).

Passenger Space

The G70 has .8 inches more front legroom, 1.2 inches more front shoulder room, .9 inches more rear legroom and .6 inches more rear shoulder room than the A-Class.

Cargo Capacity

The G70 has a much larger trunk than the A-Class (10.5 vs. 8.6 cubic feet).

Servicing Ease

The engine in the G70 is mounted longitudinally (North-South), instead of sideways, as in the A-Class. This makes it easier to service and maintain, because the accessory belts are in front.

Recommendations

The G70 was chosen as one of Car and Driver’s “Top Ten” in 2019. The A-Class has never been a Car and Driver “Top Ten” pick.

Motor Trend selected the G70 as their 2019 Car of the Year. The A-Class has never been chosen.
