The LC Series has a standard Pre-Collision System, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Dawn doesn't offer collision warning or crash mitigation brakes.

The LC Series’ blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Dawn doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the LC Series’ 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 Dawn doesn’t offer a cross-path warning system.

Both the LC Series and the Dawn have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, daytime running lights, rearview cameras, driver alert monitors and available rear parking sensors.

Lexus’ powertrain warranty covers the LC Series 2 years longer than Rolls-Royce covers the Dawn. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Dawn ends after only 4 years.

The LC Series’ corrosion warranty is 2 years longer than the Dawn’s (6 vs. 4 years).

There are almost 7 times as many Lexus dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the LC Series’ warranty.

On the EPA test cycle the LC 500 Convertible gets better fuel mileage than the Dawn with its standard engine (15 city/25 hwy vs. 12 city/18 hwy).

Regenerative brakes improve the LC Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Dawn doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the LC Series Hybrid’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Dawn doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus LC Series higher (5 to 7 out of 10) than the Rolls-Royce Dawn (3). This means the LC Series produces up to 24.5 pounds less smog-producing pollutants than the Dawn every 15,000 miles.

A 10-speed automatic is standard on the Lexus LC Series, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Dawn.

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 Dawn doesn’t offer a CVT.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LC Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the Dawn.

The Lexus LC Series may be more efficient, handle and accelerate better because it weighs about 650 to 850 pounds less than the Rolls-Royce Dawn.

The LC Series is 1 foot, 8.7 inches shorter than the Dawn, making the LC Series easier to handle, maneuver and park in tight spaces.

For excellent aerodynamics, the LC Series has standard flush composite headlights. The Dawn has recessed headlights that spoil its aerodynamic shape and create extra drag.

The LC Series Convertible uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Dawn doesn’t offer active noise cancellation.

The LC Series has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Dawn doesn’t offer a remote starting system.

On extremely cold winter days, the LC Series’ optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Dawn doesn’t offer a heated steering wheel.
