Safety

The LC Series has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The AMG C 63 Coupe doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the LC Series and the AMG C 63 Coupe 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, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

Fuel Economy and Range

On the EPA test cycle the LC 500h gets better fuel mileage than the AMG C 63 Coupe (26 city/35 hwy vs. 17 city/26 hwy).

Transmission

A 10-speed automatic is standard on the Lexus LC Series, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the AMG C 63 Coupe.

The LC 500h has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The AMG C 63 Coupe doesn’t offer a CVT.
