Safety

The RX Series has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Q8 doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The RX Series offers optional Auto Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Q8 doesn’t offer backup collision prevention brakes.

Both the RX Series and the Q8 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the RX Series the rating of “Top Pick” for 2018, a rating granted to only 100 vehicles tested by the IIHS. The Q8 has not been tested, yet.

Warranty

Lexus’ powertrain warranty covers the RX Series 2 years and 20,000 miles longer than Audi covers the Q8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q8 ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates rated the RX Series second among midsize premium SUVs in their 2018 Initial Quality Study. The Q8 isn’t in the top three in its category.

J.D. Power and Associates’ 2018 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 21 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

J.D. Power and Associates’ 2018 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 42 more problems per 100 vehicles, Audi is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Audi vehicles. Consumer Reports ranks Lexus first in reliability. Audi is ranked 7th.

Transmission

The RX 450h 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 Q8 doesn’t offer a CVT.

Suspension and Handling

For better maneuverability, the RX Series’ turning circle is 4.7 feet tighter than the Q8’s (38.8 feet vs. 43.5 feet).

For greater off-road capability the RX Series has a 2.4 inches greater minimum ground clearance than the Q8 (8.2 vs. 5.8 inches), allowing the RX Series to travel over rougher terrain without being stopped or damaged.

Chassis

The Lexus RX Series may be more efficient, handle and accelerate better because it weighs about 250 to 800 pounds less than the Audi Q8.

The RX Series is 3.8 inches shorter than the Q8, making the RX Series easier to handle, maneuver and park in tight spaces.

The design of the Lexus RX Series amounts to more than styling. The RX Series has an aerodynamic coefficient of drag of .33 Cd. That is lower than the Q8 (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the RX Series get better fuel mileage.

Passenger Space

The RX Series has 1.2 inches more front headroom, 2.4 inches more front legroom and 1 inch more rear headroom than the Q8.

Cargo Capacity

Pressing a switch automatically lowers or raises the RX Series’ optional rear seats, to make changing between cargo and passengers easier. The Q8 doesn’t offer automatic folding seats.

Ergonomics

To improve rear visibility by keeping the rear window clear, the RX Series has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q8 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Model Availability

The RX Series is available in both front-wheel drive and four-wheel drive configurations. The Q8 doesn’t offer a two-wheel drive configuration.

Recommendations

Consumer Reports® recommends the Lexus RX Series, based on reliability, safety and performance.

The Lexus RX Series outsold the Audi Q8 by over 41 to one during 2018.
