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 Soul are reminded to check the back seat if they opened the rear door before starting out. The Trax doesn’t offer a back seat reminder.

The Soul has standard Forward Collision Avoidance Assist, 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 Trax doesn't offer collision warning or crash mitigation brakes.

The Soul’s 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 Trax doesn’t offer a lane departure warning system.

Both the Soul and Trax offer rear cross-traffic warning, but the Soul with Rear Cross-Traffic Collision Warning also has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Trax’s Rear Cross Traffic Alert doesn’t automatically brake.

The Soul’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Trax doesn’t offer a driver alert monitor.

Both the Soul and the Trax 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 and available blind spot warning systems.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Kia Soul is safer than the Chevrolet Trax:

	Soul	Trax
	Driver
STARS	5 Stars	5 Stars
Neck Injury Risk	26%	26%
Neck Stress	168 lbs.	298 lbs.
Leg Forces (l/r)	49/286 lbs.	363/313 lbs.

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

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Kia Soul is safer than the Chevrolet Trax:

	Soul	Trax
	Rear Seat
STARS	5 Stars	5 Stars
Hip Force	611 lbs.	672 lbs.

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

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Soul is 3.2% to 5.1% less likely to roll over than the Trax.

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 Soul the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The Trax has not been fully tested, yet.

Warranty

The Soul comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Trax’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the Soul 5 years and 40,000 miles longer than Chevrolet covers the Trax. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Trax ends after only 5 years or 60,000 miles.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the Soul has a standard 150-amp alternator. The Trax’s 130-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Soul has a standard 760-amp battery. The Trax’s 525-amp battery isn’t as powerful.

J.D. Power and Associates rated the Soul second among small suvs in their 2023 Initial Quality Study. The Trax isn’t in the top three.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Kia vehicles are more reliable than Chevrolet vehicles. J.D. Power ranks Kia first in reliability, above the industry average. With 26 more problems per 100 vehicles, Chevrolet is ranked 10th.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Kia vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Kia 11 places higher in reliability than Chevrolet.

Fuel Economy and Range

On the EPA test cycle the Soul gets better mileage than the Trax:

			MPG
Soul
	FWD	EX 2.0 DOHC 4-cyl.	29 city/35 hwy
		2.0 DOHC 4-cyl.	27 city/33 hwy
Trax
	FWD	1.4 turbo 4-cyl.	24 city/32 hwy
	AWD	1.4 turbo 4-cyl.	23 city/30 hwy

In heavy traffic or at stoplights the Soul’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Trax doesn’t offer an automatic engine start/stop system.

The Soul has a standard locking fuel door. The fuel filler door is not lockable on the Trax. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Transmission

The Soul 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 Trax doesn’t offer a CVT.

Brakes and Stopping

The Kia Soul has standard four-wheel disc brakes for better stopping power and improved directional control in poor weather. Rear drums are standard on the Trax. Drums can heat up and make stops longer, especially with antilock brakes that work much harder than conventional brakes.

The Soul stops much shorter than the Trax:

	Soul	Trax
70 to 0 MPH	161 feet	169 feet	Car and Driver
60 to 0 MPH	120 feet	130 feet	Consumer Reports
60 to 0 MPH (Wet)	130 feet	141 feet	Consumer Reports

Tires and Wheels

For better traction, the Soul GT-Line’s tires are larger than the largest tires available on the Trax (235/45R18 vs. 215/55R18).

The Soul LX/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 Trax’s standard 70 series tires. The Soul GT-Line’s tires have a lower 45 series profile than the Trax LT’s optional 55 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the Soul’s wheelbase is 1.8 inches longer than on the Trax (102.4 inches vs. 100.6 inches).

For better handling and stability, the track (width between the wheels) on the Soul is 1.4 inches wider in the front and 1.8 inches wider in the rear than on the Trax.

The Soul handles at .91 G’s, while the Trax LT AWD pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

The Soul executes Motor Trend’s “Figure Eight” maneuver 2.4 seconds quicker than the Trax LT AWD (26.8 seconds @ .66 average G’s vs. 29.2 seconds @ .56 average G’s).

For better maneuverability, the Soul’s turning circle is .6 feet tighter than the Trax LS’ (34.8 feet vs. 35.4 feet). The Soul’s turning circle is 1.9 feet tighter than the Trax LT’s (34.8 feet vs. 36.7 feet).

Chassis

The Kia Soul may be more efficient, handle and accelerate better because it weighs about 250 to 300 pounds less than the Chevrolet Trax.

Passenger Space

The Soul has 9.4 cubic feet more passenger volume than the Trax (102.2 vs. 92.8).

The Soul has .3 inches more front headroom, .3 inches more front legroom, 1.8 inches more front hip room, 1.4 inches more front shoulder room, .7 inches more rear headroom, 3.1 inches more rear legroom, 2.1 inches more rear hip room and 1.9 inches more rear shoulder room than the Trax.

Cargo Capacity

The Soul has a much larger cargo volume with its rear seat up than the Trax with its rear seat up (24.2 vs. 18.7 cubic feet). The Soul has a much larger cargo volume with its rear seat folded than the Trax with its rear seat folded (62.1 vs. 48.4 cubic feet).

The Soul’s cargo area is larger than the Trax’s in almost every dimension:

	Soul	Trax
Length to seat (2nd/1st)	26”/59”	29.3”/57”
Max Width	45.6”	39.5”
Min Width	41.5”	36”
Height	33”	31.8”

Servicing Ease

The Soul uses gas struts to support the hood for easier service access. The Trax 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.

Ergonomics

The Soul Turbo has a standard heads-up display that projects speed in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Trax doesn’t offer a heads-up display.

The Soul GT-Line’s optional LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Trax LT’s projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen.

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

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Soul has standard extendable sun visors. The Trax doesn’t offer extendable visors.

The Soul’s optional rear view mirror has an automatic dimming feature. This mirror can be set to automatically darken quickly when headlights shine on it, keeping following vehicles from blinding or distracting the driver. The Trax doesn’t offer the luxury of an automatic dimming rear view mirror.

The Soul S/EX/GT-Line’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Trax doesn’t offer dual zone air conditioning.

The Soul S/EX/GT-Line’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Trax doesn’t offer automatic air conditioning.

To keep a safe, consistent following distance, the Soul GT-Line offers an optional Smart 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 Trax doesn’t offer an adaptive cruise control.

The Soul S/EX/GT-Line’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Trax’s available navigation system doesn’t offer real-time traffic updates.

With standard voice command, the Soul S/EX/GT-Line offers the driver hands free control of the radio and the navigation computer by simply speaking. The Trax doesn’t offer a voice control system.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Kia Soul S/EX/GT-Line has a standard wireless phone charging system (Qi) on the dashboard. The Trax doesn’t offer wireless personal charging.

Economic Advantages

Insurance will cost less for the Soul owner. The Car Book by Jack Gillis rates the Soul with a number “1” insurance rate while the Trax is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Soul is less expensive to operate than the Trax because typical repairs cost much less on the Soul than the Trax, including $174 less for a water pump, $383 less for a muffler, $17 less for front brake pads, $273 less for a fuel pump, $60 less for front struts, $454 less for a timing belt/chain and $6 less for a power steering pump.
