Safety

The Q5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RXL doesn’t offer pre-crash pretensioners.

Both the Q5 and RXL have child safety locks to prevent children from opening the rear doors. The Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The RXL’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Q5 has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RXL 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q5. But it costs extra on the RXL.

Both the Q5 and the RXL have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The Q5’s corrosion warranty is 6 years longer than the RXL’s (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 Q5’s warranty.

Reliability

The Audi Q5’s engine uses a cast iron block for durability, while the RXL’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

Engine

The Q5’s 2.0 turbo 4 cyl. produces 10 lbs.-ft. more torque (273 vs. 263) than the RX 350L’s standard 3.5 DOHC V6.

As tested in Motor Trend the Audi Q5 is faster than the RX 350L 3.5 DOHC V6:

Fuel Economy and Range

On the EPA test cycle the Q5 Auto gets better fuel mileage than the RX 350L AWD (22 city/27 hwy vs. 18 city/25 hwy).

To lower fuel costs and make buying fuel easier, the Audi Q5 uses regular unleaded gasoline (premium recommended for maximum performance). The RX 450hL requires premium, which can cost 20 to 55 cents more per gallon.

The Q5 has 1.3 gallons more fuel capacity than the RXL Hybrid’s standard fuel tank (18.5 vs. 17.2 gallons), for longer range between fill-ups.

Transmission

The Q5 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The RXL doesn’t offer an SMG or a conventional manual transmission.

The Q5’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The RXL doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Q5’s front brake rotors are larger than those on the RXL:

Consumer Reports

Tires and Wheels

For better traction, the Q5’s optional tires are larger than the largest tires available on the RXL (255/45R20 vs. 235/65R18).

The Q5’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the RXL’s standard 65 series tires. The Q5’s optional tires have a lower 45 series profile than the RXL’s optional 55 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the Q5’s wheelbase is 1.2 inches longer than on the RXL (111 inches vs. 109.8 inches).

The Q5 Prestige handles at .79 G’s, while the RX 350L AWD pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The Q5 Prestige executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the RX 350L (27.2 seconds @ .65 average G’s vs. 28.5 seconds @ .6 average G’s).

Chassis

The Audi Q5 may be more efficient, handle and accelerate better because it weighs about 400 to 850 pounds less than the Lexus RXL.

The Q5 is 1 foot, 1.3 inches shorter than the RXL, making the Q5 easier to handle, maneuver and park in tight spaces.

Passenger Space

The Q5 has 1.9 inches more front headroom, .8 inches more rear headroom and 6.9 inches more rear legroom than the RXL.

Cargo Capacity

The Q5 has a much larger cargo volume than the RXL with its rear seat up (25.1 vs. 16.3 cubic feet).

Towing

The Q5’s standard towing capacity is much higher than the RXL’s (4400 vs. 0 pounds).

Servicing Ease

The engine in the Q5 is mounted longitudinally (North-South), instead of sideways, as in the RXL. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Heated windshield washer nozzles are standard on the Q5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The RXL doesn’t offer heated windshield washer nozzles.

The Q5 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 RXL doesn’t offer an automated parking system.

Economic Advantages

According to The Car Book by Jack Gillis, the Q5 is less expensive to operate than the RXL because typical repairs cost much less on the Q5 than the RXL, including $424 less for a water pump, $1208 less for a timing belt/chain and $1629 less for a power steering pump.

Recommendations

Consumer Reports® recommends both the Audi Q5 and the Lexus RXL, based on reliability, safety and performance.
