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 UX Series doesn’t offer pre-crash pretensioners.
For enhanced safety, the front shoulder belts of the Cadillac XT5 are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Lexus UX Series has only front height-adjustable seat belts.
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 UX Series doesn’t offer a back seat reminder.
The XT5 Platinum has a standard Surround Vision to allow the driver to see objects all around the vehicle on a screen. The UX 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 XT5 and the UX Series have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, crash mitigating brakes, 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 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 154 vehicles tested by the IIHS. The UX Series has not been tested, yet.
There are almost 4 times as many Cadillac dealers as there are Lexus dealers, which makes it much easier should you ever need service under the XT5’s warranty.
The XT5’s 3.6 DOHC V6 produces 141 more horsepower (310 vs. 169) and 120 lbs.-ft. more torque (271 vs. 151) than the UX 200’s standard 2.0 DOHC 4 cyl. The XT5’s 3.6 DOHC V6 produces 129 more horsepower (310 vs. 181) than the UX 250h’s standard 2.0 DOHC 4 cyl. hybrid.
An engine control system that can shut down half of the engine’s cylinders helps improve the XT5’s fuel efficiency. The UX Series doesn’t offer a system that can shut down part of the engine.
The XT5 FWD’s standard fuel tank has 8.8 gallons more fuel capacity than the UX Series Hybrid’s standard fuel tank (19.4 vs. 10.6 gallons), for longer range between fill-ups. The XT5 AWD’s standard fuel tank has 9.3 gallons more fuel capacity than the UX Series’ standard fuel tank (21.7 vs. 12.4 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 UX Series doesn’t offer a cap-less fueling system.
For better stopping power the XT5’s brake rotors are larger than those on the UX Series:
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 UX Series are solid, not vented.
For better traction, the XT5 has larger tires than the UX Series (235/65R18 vs. 225/50R18).
For better ride, handling and brake cooling the XT5 offers optional 20-inch wheels. The UX Series’ largest wheels are only 18-inches.
The Cadillac XT5’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Lexus UX Series only has 5 wheel lugs per wheel.
The XT5 offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the UX Series; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
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 UX Series’ suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the XT5’s wheelbase is 8.6 inches longer than on the UX Series (112.5 inches vs. 103.9 inches).
For better handling and stability, the track (width between the wheels) on the XT5 is 3.4 inches wider in the front and 3.4 inches wider in the rear than on the UX Series.
The XT5 has 1.2 inches more front headroom, 2.2 inches more front hip room, 3.2 inches more front shoulder room, 6.4 inches more rear legroom, 2.4 inches more rear hip room and 3.3 inches more rear shoulder room than the UX Series.
For enhanced passenger comfort on long trips the XT5’s rear seats recline. The UX Series’ rear seats don’t recline.
The XT5 has a much larger cargo volume with its rear seat up than the UX Series (30 vs. 21.7 cubic feet).
Pressing a switch automatically lowers the XT5’s rear seats, to make changing between passengers and cargo easier. The UX Series doesn’t offer automatic folding seats.
The XT5 has a 1000 lbs. towing capacity. The UX Series has no towing capacity.
The XT5 uses gas struts to support the hood for easier service access. The UX Series uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.
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 UX Series does not have an oil pressure gauge.
The power windows standard on both the XT5 and the UX Series have locks to prevent small children from operating them. When the lock on the XT5 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The UX Series prevents the driver from operating the other windows just as it does the other passengers.
Both the XT5 and the UX Series 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 UX Series.
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 UX Series doesn’t offer an automated parking system.
