Safety

The AMG C 63 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.

Using vehicle speed sensors, smart airbags in the AMG C 63 Coupe deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The AMG C 63 Coupe’s side airbags will shut off if a child is leaning against the door. The LC Series’ airbags don’t have smart features and will always deploy full force.

The AMG C 63 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 AMG C 63 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 AMG C 63 Coupe and the LC Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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 and available lane departure warning systems.

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 AMG C 63 Coupe’s warranty.

Engine

The AMG C 63 Coupe’s standard 4.0 turbo V8 produces 115 more horsepower (469 vs. 354) than the LC 500h’s standard 3.5 DOHC V6 hybrid. The AMG C 63 Coupe’s 4.0 turbo V8 produces 81 lbs.-ft. more torque (479 vs. 398) than the LC 500’s standard 5.0 DOHC V8. The AMG C 63 S Coupe’s standard 4.0 turbo V8 produces 32 more horsepower (503 vs. 471) and 118 lbs.-ft. more torque (516 vs. 398) than the LC 500’s standard 5.0 DOHC V8.

Fuel Economy and Range

On the EPA test cycle the AMG C 63 Coupe gets better fuel mileage than the LC 500 (17 city/26 hwy vs. 16 city/26 hwy).

Regardless of its engine, the AMG C 63 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.

Transmission

The AMG C 63 Coupe 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 LC Series doesn’t offer an SMG or a conventional manual transmission.

The AMG C 63 Coupe’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 LC Series doesn’t offer launch control.

Brakes and Stopping

The AMG C 63 Coupe S 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 LC Series doesn’t offer ceramic brake rotors.

The AMG C 63 Coupe stops much shorter than the LC Series:

Car and Driver

Tires and Wheels

For better traction, the AMG C 63 Coupe’s tires are larger than the largest tires available on the LC Series (F:255/40R18 & R:285/35R18 vs. F:245/45R20 & R:275/40R20).

The AMG C 63 Coupe’s standard 255/40R18 front and 285/35R18 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the LC Series’ standard 45 series front and 40 series rear tires. The AMG C 63 S Coupe’s optional 255/35R19 front and 285/30R20 rear tires have a lower 35 series front and 30 series rear profile than the LC Series’ optional 40 series front and 35 series rear tires.

Suspension and Handling

The AMG C 63 Coupe has a standard 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 AMG C 63 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.

The AMG C 63 S Coupe handles at .98 G’s, while the LC 500h pulls only .91 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The AMG C 63 Coupe has 1.6 inches more front headroom, 3.4 inches more rear headroom and 2.8 inches more rear shoulder room than the LC Series.

Cargo Capacity

The AMG C 63 Coupe has a much larger trunk than the LC Series (10.5 vs. 5.4 cubic feet).

The AMG C 63 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 AMG C 63 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 AMG C 63 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 see further while navigating curves, the AMG C 63 Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The LC Series doesn’t offer cornering lights.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG C 63 Coupe has standard extendable sun visors. The LC Series doesn’t offer extendable visors.

When the AMG C 63 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 AMG C 63 Coupe has standard rear a/c vents to keep rear occupants more comfortable. The LC Series doesn’t offer rear vents.

The AMG C 63 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 AMG C 63 comes in coupe, convertible and sedan bodystyles; the Lexus LC Series isn’t available as a convertible or sedan.
