Safety

The XT5’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Q3 doesn’t offer pre-crash pretensioners.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT5 are reminded to check the back seat if they opened the rear door before starting out. The Q3 doesn’t offer a back seat reminder.

The XT5 offers optional Forward Automatic Braking, which use 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 Q3 doesn't offer collision warning or crash mitigation brakes.

Over 200 people are killed each year when backed over by motor vehicles. The XT5 offers optional Reverse Automatic Braking which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Q3 doesn’t offer backup collision prevention brakes.

The XT5’s optional 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 Q3 doesn’t offer a lane departure warning system.

The XT5 Platinum has a standard Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Q3 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.

To help make backing safer, the XT5’s optional 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 Q3 doesn’t offer a cross-path warning system.

The XT5 has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Q3 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the XT5 and the Q3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive and blind spot warning systems.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the XT5 the rating of “Top Pick” for 2017, a rating granted to only 149 vehicles tested by the IIHS. The Q3 was not even a “Top Pick” for 2016.

Warranty

Cadillac’s powertrain warranty covers the XT5 2 years and 20,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

There are over 3 times as many Cadillac dealers as there are Audi dealers, which makes it much easier should you ever need service under the XT5’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the XT5 has a standard 155-amp alternator (170-amp - XT5 optional). The Q3’s 140-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Cadillac 12th in initial quality, above the industry average. With 15 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

Engine

The XT5’s 3.6 DOHC V6 produces 110 more horsepower (310 vs. 200) and 64 lbs.-ft. more torque (271 vs. 207) than the Q3’s 2.0 turbo 4 cyl.

As tested in Car and Driver the Cadillac XT5 is faster than the Audi Q3:

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the XT5’s fuel efficiency. The Q3 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the XT5’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Q3 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Cadillac XT5 uses regular unleaded gasoline. The Q3 requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The XT5 FWD’s standard fuel tank has 2.5 gallons more fuel capacity than the Q3 (19.4 vs. 16.9 gallons), for longer range between fill-ups. The XT5 AWD’s standard fuel tank has 4.8 gallons more fuel capacity than the Q3 (21.7 vs. 16.9 gallons).

The XT5 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Q3 doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT5 higher (5 out of 10) than the Audi Q3 (3). This means the XT5 produces up to 16.5 pounds less smog-producing pollutants than the Q3 every 15,000 miles.

Transmission

An eight-speed automatic is standard on the Cadillac XT5, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Q3.

Brakes and Stopping

For better stopping power the XT5’s brake rotors are larger than those on the Q3:

 

XT5

Q3

Front Rotors

13.6 inches

12.3 inches

Rear Rotors

12.4 inches

11.1 inches

The XT5’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Q3 are solid, not vented.

Tires and Wheels

For better traction, the XT5 has larger tires than the Q3 (235/65R18 vs. 225/40R19).

For better ride, handling and brake cooling the XT5 offers optional 20-inch wheels. The Q3’s largest wheels are only 19-inches.

The Cadillac XT5’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi Q3 only has 5 wheel lugs per wheel.

Suspension and Handling

The XT5 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 or off-road. The Q3’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the XT5’s wheelbase is 10 inches longer than on the Q3 (112.5 inches vs. 102.5 inches).

For better handling and stability, the track (width between the wheels) on the XT5 is 3.3 inches wider in the front and 3.2 inches wider in the rear than on the Q3.

For greater off-road capability the XT5 has a 1.1 inches greater minimum ground clearance than the Q3 (7.8 vs. 6.7 inches), allowing the XT5 to travel over rougher terrain without being stopped or damaged.

Chassis

As tested by Car and Driver while cruising at 70 MPH, the interior of the XT5 4x4 is quieter than the Q3 Prestige Quattro (68 vs. 71 dB).

Passenger Space

The XT5 has 1.4 inches more front headroom, 1.2 inches more front legroom, 2.5 inches more front shoulder room, 8.4 inches more rear legroom and 2.6 inches more rear shoulder room than the Q3.

For enhanced passenger comfort on long trips the XT5’s rear seats recline. The Q3’s rear seats don’t recline.

Cargo Capacity

The XT5 has a much larger cargo area with its rear seat up than the Q3 with its rear seat up (30 vs. 16.7 cubic feet). The XT5 has a much larger cargo area with its rear seat folded than the Q3 with its rear seat folded (63 vs. 50.3 cubic feet).

Pressing a switch automatically lowers the XT5’s rear seats, to make changing between passengers and cargo easier. The Q3 doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the XT5 Platinum’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Q3 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

Maximum trailer towing in the Audi Q3 is limited to 2200 pounds. The XT5 offers up to a 3500 lbs. towing capacity.

Servicing Ease

The XT5 has a maintenance free battery for long life without checking the battery’s water level. The Q3 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Ergonomics

The XT5 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 Q3 doesn’t offer a remote starting system.

When two different drivers share the XT5, the optional memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position and outside mirror angle. The Q3 doesn’t offer a memory system.

The XT5’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q3 doesn’t offer an easy entry system.

The XT5’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Q3 does not have an oil pressure gauge.

The XT5 Platinum has a standard 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 Q3 doesn’t offer a heads-up display.

On a hot day the XT5’s driver can lower all the windows from a distance using the keyless remote. The driver of the Q3 can’t use the remote to operate the windows.

To improve rear visibility by keeping the rear window clear, the XT5 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

While driving with high beams on, sensitive light sensors available for the XT5 detect other vehicles which could be blinded and automatically switch to low beams. The Q3 doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the XT5 offers optional cornering lights to illuminate around corners when the turn signals are activated. The Q3 doesn’t offer cornering lights.

When the XT5 with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Q3’s mirrors don’t automatically adjust for backing.

The XT5 offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Q3 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the XT5 and the Q3 offer optional heated front seats. The XT5 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q3.

Standard air-conditioned seats in the XT5 Premium/Platinum keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q3 doesn’t offer air-conditioned seats.

On extremely cold winter days, the XT5’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Q3 doesn’t offer a heated steering wheel.

To keep a safe, consistent following distance, the XT5 offers an optional Adaptive 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 Q3 doesn’t offer an adaptive cruise control.

The XT5’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Q3 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the XT5 owner. The Car Book by Jack Gillis rates the XT5 with a number “8” insurance rate while the Q3 is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the XT5 is less expensive to operate than the Q3 because typical repairs cost much less on the XT5 than the Q3, including $125 less for a water pump, $301 less for a starter, $492 less for front struts and $292 less for a power steering pump.

Recommendations

The Cadillac XT5 outsold the Audi Q3 by over three to one during 2017.
