Compare the2023 Porsche 911VS 2022 Mercedes AMG E-Class Coupe

A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The AMG E-Class Coupe doesn’t offer a night vision system.

Both the 911 and the AMG E-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The 911’s corrosion warranty is 7 years longer than the AMG E-Class Coupe’s (12 vs. 5 years).

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Porsche above average in long-term dependability. With 30 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

The 911 S’ standard 3.0 turbo 6-cylinder produces 14 more horsepower (443 vs. 429) and 6 lbs.-ft. more torque (390 vs. 384) than the AMG E-Class Coupe’s 3.0 turbo 6-cylinder hybrid. The 911 GTS/Dakar’s standard 3.0 turbo 6-cylinder produces 44 more horsepower (473 vs. 429) and 36 lbs.-ft. more torque (420 vs. 384) than the AMG E-Class Coupe’s 3.0 turbo 6-cylinder hybrid. The 911 GT3’s standard 4.0 DOHC 6-cylinder produces 73 more horsepower (502 vs. 429) than the AMG E-Class Coupe’s 3.0 turbo 6-cylinder hybrid. The 911 Turbo S’ standard 3.7 turbo 6-cylinder produces 211 more horsepower (640 vs. 429) and 206 lbs.-ft. more torque (590 vs. 384) than the AMG E-Class Coupe’s 3.0 turbo 6-cylinder hybrid.

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The AMG E-Class Coupe doesn’t offer a boxer engine configuration.

The 911’s optional fuel tank has 6.3 gallons more fuel capacity than the AMG E-Class Coupe (23.7 vs. 17.4 gallons).

The 911 offers a manual transmission for better acceleration, control and fuel economy. The AMG E-Class Coupe doesn’t offer a manual transmission.

The 911 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 AMG E-Class Coupe doesn’t offer an SMG.

The 911’s optional 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 AMG E-Class Coupe doesn’t offer launch control.

For better stopping power the 911 Turbo S/Sport Classic’s front brake rotors are larger than those on the AMG E-Class Coupe:

The 911 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The AMG E-Class Coupe doesn’t offer ceramic brake rotors.

The 911 stops much shorter than the AMG E-Class Coupe:

For better traction, the 911 Turbo S/GT3/Sport Classic’s tires are larger than the largest tires available on the AMG E-Class Coupe (F:255/35R20 & R:315/30R21 vs. F:245/40R19 & R:275/35R19).

For better ride, handling and brake cooling the 911 has standard 20-inch rear wheels. Smaller 19-inch wheels are standard on the AMG E-Class Coupe. The 911’s optional 21-inch rear wheels are larger than the 20-inch wheels optional on the AMG E-Class Coupe.

The 911 (except Base/GT3) offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The AMG E-Class Coupe doesn’t offer an active sway bar system.

The 911 GT3 handles at 1.15 G’s, while the AMG E 53 Coupe pulls only .91 G’s of cornering force in a Motor Trend skidpad test.

The 911 GT3 executes Motor Trend’s “Figure Eight” maneuver 3 seconds quicker than the AMG E 53 Coupe (22.3 seconds @ .95 average G’s vs. 25.3 seconds @ .74 average G’s).

For better maneuverability, the 911 GT3’s turning circle is 5.6 feet tighter than the AMG E-Class Coupe’s (34.1 feet vs. 39.7 feet). The 911’s turning circle is 2.9 feet tighter than the AMG E-Class Coupe’s (36.8 feet vs. 39.7 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 650 to 1300 pounds less than the Mercedes AMG E-Class Coupe.

The 911 is 1 foot shorter than the AMG E-Class Coupe, making the 911 easier to handle, maneuver and park in tight spaces.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The AMG E-Class Coupe doesn’t offer active grille shutters.

The 911 has .2 inches more front headroom and .3 inches more front legroom than the AMG E-Class Coupe.

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Mercedes. J.D. Power ranks Porsche third in service department satisfaction. With a 30% lower rating, Mercedes is ranked 18th.

To improve rear visibility by keeping the rear window clear, the 911 (except Cabriolet/GT3) offers an optional rear wiper. The AMG E-Class Coupe doesn’t offer a rear wiper.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The AMG E-Class Coupe’s automatic parking system does not offer parking by remote control.

The 911 is available in both rear-wheel drive and all-wheel drive configurations. The AMG E-Class Coupe doesn’t offer a two-wheel drive configuration.

J.D. Power and Associates rated the 911 first among premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The AMG E-Class Coupe isn’t in the top three.
