2017 Mercedes S-Class

Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes S-Class has only front height-adjustable seat belts.

To help make backing safer, the G80’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 S-Class doesn’t offer a cross-path warning system.

Both the G80 and the S-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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 rear parking sensors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Pick Plus” for 2017, a rating granted to only 53 vehicles tested by the IIHS. The S-Class has not been tested, yet.

Warranty Comparison

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 S-Class’ 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 Mercedes covers the S-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 S-Class ends after only 4 years or 50,000 miles.

The G80’s corrosion warranty is 2 years longer than the S-Class’ (7 vs. 5 years).

Genesis pays for scheduled maintenance on the G80 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 S-Class.

Reliability Comparison

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 G80’s reliability 24 points higher than the S-Class.

J.D. Power and Associates rated the G80 third among midsize premium cars in their 2016 Initial Quality Study. The S-Class isn’t in the top three in its category.

Fuel Economy and Range Comparison

To lower fuel costs and make buying fuel easier, the Genesis G80 uses regular unleaded gasoline (premium recommended on G80 5.0 for maximum performance). The S-Class requires premium, which can cost 20 to 55 cents more per gallon.

The G80 has 3.7 gallons more fuel capacity than the S-Class 550e Hybrid’s standard fuel tank (20.3 vs. 16.6 gallons), for longer range between fill-ups.

Consumer Reports

Suspension and Handling Comparison

For better handling and stability, the average track (width between the wheels) on the G80 is .9 inches wider in the front and 1.6 inches wider in the rear than the track on the S-Class.

The G80 5.0 handles at .86 G’s, while the S550e pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the G80’s turning circle is 1.9 feet tighter than the S65 AMG’s (36.2 feet vs. 38.1 feet). The G80’s turning circle is 3.8 feet tighter than the S550’s (36.2 feet vs. 40 feet).

Chassis Comparison

The Genesis G80 may be more efficient, handle and accelerate better because it weighs about 350 to 750 pounds less than the Mercedes S-Class.

The G80 is 10 inches shorter than the S-Class, making the G80 easier to handle, maneuver and park in tight spaces.

The design of the Genesis G80 amounts to more than styling. The G80 has an aerodynamic coefficient of drag of .26 Cd. That is lower than the S-Class (.27 to .28) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G80 get better fuel mileage.

As tested by Car and Driver while at idle, the interior of the G80 5.0 is quieter than the S550 (39 vs. 40 dB).

Passenger Space Comparison

The G80 has 1.4 inches more front headroom, 4.3 inches more front legroom and .8 inches more rear headroom than the S-Class.

According to The Car Book by Jack Gillis, the G80 is less expensive to operate than the S-Class because typical repairs cost much less on the G80 than the S-Class, including $580 less for a water pump, $900 less for an alternator, $65 less for front brake pads, $289 less for a starter, $227 less for fuel injection, $87 less for a fuel pump, $2618 less for front struts and $883 less for a power steering pump.
