The S5’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.

The S5 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The LC Series doesn’t offer all-wheel drive.

The S5 Prestige has a standard Top and Corner View Cameras 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.

Both the S5 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, post-collision automatic braking systems, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the S5 the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The LC Series has not been tested, yet.


The S5’s corrosion warranty is 6 years longer than the LC Series’ (12 vs. 6 years).

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the S5’s warranty.

All-wheel drive, available in the S5, 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.

The S5 stops much shorter than the LC Series:

Car and Driver

Tires and Wheels

For better traction, the S5’s optional tires are larger than the largest tires available on the LC Series (265/30R20 vs. 245/45R20).

The S5’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the LC Series’ standard 45 series front tires. The S5’s optional tires have a lower 30 series profile than the LC Series’ optional 40 series front and 35 series rear tires.

Suspension and Handling

The S5 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 S5 Prestige Coupe handles at .94 G’s, while the LC 500h pulls only .91 G’s of cornering force in a Car and Driver skidpad test.


The Audi S5 may be more efficient, handle and accelerate better because it weighs about 200 to 450 pounds less than the Lexus LC Series.

As tested by Car and Driver, the interior of the S5 Prestige Coupe is quieter than the LC 500h:

42 dB

Passenger Space

The S5 Coupe has 1.8 inches more front headroom, 3.9 inches more rear headroom, .2 inches more rear legroom and 1.8 inches more rear shoulder room than the LC Series.

Cargo Capacity

The S5 Coupe has a much larger trunk than the LC Series (11.6 vs. 5.4 cubic feet).

The S5’s standard rear seats fold to accommodate long and bulky cargo. The LC Series doesn’t offer folding rear seats.

To make loading groceries and cargo easier when your hands are full, the S5’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The LC Series doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.


Heated windshield washer nozzles are standard on the S5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The LC Series doesn’t offer heated windshield washer nozzles.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the S5 has standard extendable sun visors. The LC Series doesn’t offer extendable visors.

When the S5 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 S5 has standard rear a/c vents to keep rear occupants more comfortable. The LC Series doesn’t offer rear vents.

The S5 Prestige’s Park Steering 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 Audi S5 comes in coupe, convertible and four-door hatchback bodystyles; the Lexus LC Series isn’t available as a convertible or four-door.

Economic Advantages

Insurance will cost less for the S5 owner. The Complete Car Cost Guide estimates that insurance for the S5 will cost $1165 to $3015 less than the LC Series over a five-year period.

The S5 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S5 will retain 48.53% to 51.66% 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 Audi S5 will be $25678 to $34118 less than for the Lexus LC Series.


The Audi A5/S5/RS 5 outsold the Lexus LC Series by over twelve to one during the 2018 model year.
