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 R8 doesn't offer collision warning or crash mitigation brakes.
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 R8 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.
The LC Series’ lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The R8 doesn’t offer a lane departure warning system.
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 R8 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 R8 doesn’t offer a cross-path warning system.
The LC Series’ 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 R8 doesn’t offer a driver alert monitor.
Both the LC Series and the R8 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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 and available rear parking sensors.
The Lexus LC Series weighs 620 to 919 pounds more than the Audi R8. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
Lexus’ powertrain warranty covers the LC Series 2 years and 20,000 miles longer than Audi covers the R8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the R8 ends after only 4 years or 50,000 miles.
The R8’s redline is at 8700 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The LC Series has a 6600 to 7300 RPM redline.
J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Lexus 8th in initial quality, above the industry average. With 16 more problems per 100 vehicles, Audi is ranked 22nd, below the industry average.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Audi vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 18 more problems per 100 vehicles, Audi is ranked 8th.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Lexus vehicles are more reliable than Audi vehicles. Consumer Reports ranks Lexus first in reliability. Audi is ranked 14th.
On the EPA test cycle the LC 500h Auto gets better fuel mileage than the R8 V10 SMG (27 city/35 hwy vs. 13 city/20 hwy).
On the EPA test cycle the LC 500 gets better fuel mileage than the R8 V10 Auto (16 city/25 hwy vs. 13 city/20 hwy).
Regenerative brakes improve the LC Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The R8 doesn’t offer a regenerative braking system.
The LC Series’ standard fuel tank has 2.4 gallons more fuel capacity than the R8 V10 Performance’s standard fuel tank (21.7 vs. 19.3 gallons), for longer range between fill-ups.
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 Audi R8 (1). This means the LC Series produces up to 47 pounds less smog-producing pollutants than the R8 every 15,000 miles.
A ten-speed automatic is standard on the Lexus LC Series, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the R8.
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 R8 doesn’t offer a CVT.
For better stopping power the LC Series’ brake rotors are larger than those on the R8:
For better ride, handling and brake cooling the LC Series has standard 20-inch wheels. Smaller 19-inch wheels are standard on the R8. The LC Series’ optional 21-inch wheels are larger than the 20-inch wheels optional on the R8.
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. The R8 doesn’t offer run-flat tires.
For a smoother ride and more stable handling, the LC Series’ wheelbase is 8.7 inches longer than on the R8 (113 inches vs. 104.3 inches).
For better handling and stability, the track (width between the wheels) on the LC Series is 1.4 inches wider in the rear than on the R8.
For better maneuverability, the LC Series’ turning circle is 1.3 feet tighter than the R8’s (35.4 feet vs. 36.7 feet).
The design of the Lexus LC Series amounts to more than styling. The LC Series has an aerodynamic coefficient of drag of .33 Cd. That is lower than the R8 (.35). A more efficient exterior helps the LC Series go faster and keeps the interior quieter. It also helps the LC Series get better fuel mileage.
The LC Series has standard seating for 4 passengers; the R8 can only carry 2.
The LC Series has 35.9 cubic feet more passenger volume than the R8 (85.9 vs. 50).
The LC Series has 1.1 inches more front legroom and 1.4 inches more front shoulder room than the R8.
The LC Series has a much larger trunk than the R8 Coupe (5.4 vs. 4 cubic feet).
With its coupe body style, valet key and remote trunk release lockout, the LC Series offers cargo security. The R8’s non-lockable remote release defeats cargo security.
J.D. Power and Associates surveys of service recipients show that Lexus service is better than Audi. J.D. Power ranks Lexus second in service department satisfaction. With a 24% lower rating, Audi is ranked 8th.
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 R8 doesn’t offer a remote starting system.
The LC Series offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The R8 doesn’t offer a heads-up display.
The LC Series’ standard power windows have a locking feature to keep children from operating them, but the driver can still raise and lower both of them with the lock engaged. Audi does not offer a locking feature on the R8’s power windows.
The LC Series’ sun-visors swivel front-to-side to block glare from the side windows. The R8’s visors are fixed into the windshield header.
Standard air-conditioned seats in the LC Series keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The R8 doesn’t offer air-conditioned seats.
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 R8 doesn’t offer a heated steering wheel.
To keep a safe, consistent following distance, the LC Series has a standard Dynamic Radar Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The R8 doesn’t offer an adaptive cruise control.
The LC Series was chosen as one of Automobile Magazine’s “All Stars” in 2018. The R8 has never been an “All Star.”
