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 XT4 doesn’t offer pre-crash pretensioners.

Both the Q5 and XT4 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 XT4’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 a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The XT4 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 XT4.

Both the Q5 and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Q5 the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The XT4 has not been fully tested, yet.

Warranty

The Q5’s corrosion warranty is 6 years longer than the XT4’s (12 vs. 6 years).

Reliability

The Audi Q5’s engines use a cast iron block for durability, while the XT4’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

Engine

The Q5 45 TFSI’s standard 2.0 turbo 4-cylinder hybrid produces 26 more horsepower (261 vs. 235) and 15 lbs.-ft. more torque (273 vs. 258) than the XT4’s 2.0 turbo 4-cylinder. The Q5 55 TFSI e’s standard 2.0 turbo 4-cylinder hybrid produces 127 more horsepower (362 vs. 235) and 111 lbs.-ft. more torque (369 vs. 258) than the XT4’s 2.0 turbo 4-cylinder.

As tested in Car and Driver the Q5 55 TFSI e is faster than the Cadillac XT4:

	Q5	XT4
Zero to 60 MPH	4.5 sec	7.8 sec
Zero to 100 MPH	12.2 sec	23 sec
5 to 60 MPH Rolling Start	4.9 sec	8.2 sec
Passing 30 to 50 MPH	3 sec	4.2 sec
Passing 50 to 70 MPH	3.9 sec	5.4 sec
Quarter Mile	13.2 sec	16.1 sec
Speed in 1/4 Mile	104 MPH	87 MPH

Fuel Economy and Range

On the EPA test cycle the Q5 running on electricity gets better mileage than the XT4:

			MPGe
Q5
	AWD	55 TFSI e Electric Motor	60 city/61 hwy
XT4
			MPG
	FWD	2.0 turbo 4-cyl.	24 city/29 hwy
	AWD	2.0 turbo 4-cyl.	23 city/28 hwy

On the EPA test cycle the Q5 running its gasoline engine gets better mileage than the XT4:

			MPG
Q5
	AWD	55 TFSI e 2.0 turbo 4-cyl. Hybrid	25 city/27 hwy
		40 TFSI 2.0 turbo 4-cyl. Hybrid	23 city/29 hwy
XT4
	AWD	2.0 turbo 4-cyl.	23 city/28 hwy

The Q5 55 TFSI e can travel with zero emissions for 22 miles. The XT4 can’t move without running its internal combustion engine.

Regenerative brakes improve the Q5’s fuel efficiency by converting inertia back into energy instead of wasting it. The XT4 doesn’t offer a regenerative braking system.

The Q5’s standard fuel tank has 2.2 gallons more fuel capacity than the XT4 AWD’s standard fuel tank (18.5 vs. 16.3 gallons).

The Q5 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the XT4. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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 XT4 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 XT4 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Q5’s brake rotors are larger than those on the XT4:

	Q5 40/45 TFSI	Q5 55 TFSI e	XT4
Front Rotors	13.3 inches	13.8 inches	12.6 inches
Rear Rotors	13 inches	13 inches	12.4 inches

The Q5 stops much shorter than the XT4:

	Q5	XT4
70 to 0 MPH	161 feet	172 feet	Car and Driver

Tires and Wheels

For better traction, the Q5’s optional tires are larger than the largest tires available on the XT4 (255/45R20 vs. 245/45R20).

Suspension and Handling

The Q5 55 TFSI e has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q5’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The XT4 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Q5’s wheelbase is 1.6 inches longer than on the XT4 (111 inches vs. 109.4 inches).

The Q5 45 TFSI Prestige executes Motor Trend’s “Figure Eight” maneuver quicker than the XT4 Sport AWD (27.2 seconds @ .65 average G’s vs. 27.6 seconds @ .61 average G’s).

For greater off-road capability the Q5 55 TFSI e has a 1.3 inches greater minimum ground clearance than the XT4 (8 vs. 6.7 inches), allowing the Q5 to travel over rougher terrain without being stopped or damaged. The Q5 45 TFSI’s minimum ground clearance is 1.5 inches higher than on the XT4 (8.2 vs. 6.7 inches).

Passenger Space

The Q5 has .2 inches more front headroom, .7 inches more front shoulder room, 1 inch more rear headroom and 1.4 inches more rear shoulder room than the XT4.

For enhanced passenger comfort on long trips the Q5’s rear seats recline. The XT4’s rear seats don’t recline.

Cargo Capacity

The Q5 has a much larger cargo volume with its rear seat up than the XT4 with its rear seat up (25.9 vs. 22.5 cubic feet). The Q5 has a much larger cargo volume with its rear seat folded than the XT4 with its rear seat folded (54.1 vs. 48.9 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the Q5 easier. The Q5’s cargo hatch lift-over height is 29 inches, while the XT4’s liftover is 30.5 inches.

The Q5’s cargo area is larger than the XT4’s in almost every dimension:

	Q5	XT4
Length to seat (2nd/1st)	36”/69”	37.5”/67.4”
Max Width	48.5”	50”
Min Width	41”	38.7”
Height	29.7”	26.6”

Pulling a handle automatically lowers the Q5’s rear seats, to make changing between passengers and cargo easier. The XT4 doesn’t offer automatic folding seats.

Towing

The Q5’s standard towing capacity is much higher than the XT4’s (4400 vs. 2000 pounds).

Servicing Ease

The engine in the Q5 is mounted longitudinally (North-South), instead of sideways, as in the XT4. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The Q5’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The XT4’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the Q5 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the XT4 can only close the windows from inside the vehicle, with the ignition on.

The Q5’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The XT4’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 XT4 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q5 Prestige has standard headlight washers to keep headlight output high. The XT4 doesn’t offer headlight washers.

Manual rear side window sunshades are available in the Q5 to help block heat and glare for the rear passengers. The XT4 doesn’t offer rear side window sunshades.

The Q5 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the XT4.

Economic Advantages

Insurance will cost less for the Q5 owner. The Car Book by Jack Gillis rates the Q5 with a number “5” insurance rate while the XT4 is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the Q5 is less expensive to operate than the XT4 because it costs $282 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q5 than the XT4, including $44 less for a muffler, $271 less for a timing belt/chain and $320 less for a power steering pump.

Recommendations

The Audi Q5/SQ5 outsold the Cadillac XT4 by almost three to one during 2022.
