Safety

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

For enhanced safety, the front seat shoulder belts of the Mercedes E-Class Coupe 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 Lexus LC Series doesn’t offer height-adjustable seat belts.

The E-Class Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The LC Series doesn’t offer all-wheel drive.

The E-Class Coupe offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The LC Series only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The E-Class Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The LC Series doesn’t offer a driver alert monitor.

Both the E-Class Coupe and the LC Series have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and rear cross-path warning.

Warranty

There are over 59 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the E-Class Coupe’s warranty.

Engine

The E 450 Coupe’s standard 3.0 turbo V6 produces 8 more horsepower (362 vs. 354) than the LC 500h’s standard 3.5 DOHC V6 hybrid.

Fuel Economy and Range

On the EPA test cycle the E 450 Coupe RWD gets better fuel mileage than the LC 500 (20 city/28 hwy vs. 16 city/26 hwy).

Regardless of its engine, the E-Class Coupe’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.) Lexus only offers an automatic engine start/stop system on the LC Series Hybrid.

Drivetrain

All wheel drive, available in the E-Class Coupe, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Lexus LC Series is not available with all wheel drive.

Brakes and Stopping

The E-Class Coupe stops shorter than the LC Series:

Tires and Wheels

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

Suspension and Handling

The E-Class Coupe offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The LC Series’ suspension doesn’t offer adjustable shock absorbers.

The E-Class Coupe has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The E-Class Coupe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The LC Series doesn’t offer a load leveling suspension.

The E-Class Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The LC Series doesn’t offer drift compensation steering.

Chassis

The Mercedes E-Class Coupe may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Lexus LC Series.

To almost totally eliminate engine vibration in the passenger area, the E-Class Coupe has an electronically controlled liquid-filled main engine mount. A computer controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The LC Series uses conventional solid rubber engine mounts.

Passenger Space

The E-Class Coupe has standard seating for 5 passengers; the LC Series can only carry 4.

The E-Class Coupe has 3.1 cubic feet more passenger volume than the LC Series (89 vs. 85.9).

The E-Class Coupe has 3.7 inches more front headroom, 4.2 inches more rear headroom, 1.6 inches more rear legroom and 1.4 inches more rear shoulder room than the LC Series.

Cargo Capacity

The E-Class Coupe has a much larger trunk than the LC Series (10 vs. 5.4 cubic feet).

The E-Class Coupe’s standard rear seats fold to accommodate long and bulky cargo. The LC Series doesn’t offer folding rear seats.

To make loading and unloading groceries and cargo easier when your hands are full, the E-Class Coupe’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The LC Series doesn’t offer a power or hands-free opening trunk.

Ergonomics

Unlike the driver-only memory system in the LC Series, the E-Class Coupe has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

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

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the E-Class Coupe has standard extendable sun visors. The LC Series doesn’t offer extendable visors.

A power rear sunshade is optional in the E-Class Coupe to help block heat and glare for the rear passengers. The LC Series doesn’t offer a rear sunshade.

When the E-Class Coupe is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The LC Series’ mirror doesn’t automatically adjust for backing.

For greater rear passenger comfort, the E-Class Coupe has standard rear a/c vents to keep rear occupants more comfortable. The LC Series doesn’t offer rear vents.

The E-Class Coupe offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The LC Series doesn’t offer a house-current electrical outlet.

The E-Class Coupe’s optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The LC Series doesn’t offer an automated parking system.

Model Availability

The Mercedes E-Class comes in coupe, convertible, sedan and station wagon bodystyles; the Lexus LC Series isn’t available as a convertible, sedan or station wagon.

Economic Advantages

Insurance will cost less for the E-Class Coupe owner. The Complete Car Cost Guide estimates that insurance for the E-Class Coupe will cost $5230 to $5855 less than the LC Series over a five-year period.

The E-Class Coupe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the E-Class Coupe will retain 45.37% to 46.28% of its original price after five years, while the LC Series only retains 39.92% to 41.34%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mercedes E-Class Coupe will be $31979 to $33335 less than for the Lexus LC Series.

Recommendations

The E-Class was chosen as one of Car and Driver’s “Top Ten” in 2018. The LC Series has never been a Car and Driver “Top Ten” pick.

The Mercedes E-Class outsold the Lexus LC Series by almost 20 to one during the 2018 model year.
