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 Blazer are reminded to check the back seat if they opened the rear door before starting out. The Sorento doesn’t offer a back seat reminder.
The Blazer 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 Sorento 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 Blazer and the Sorento have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Blazer’s corrosion warranty is 1 year longer than the Sorento’s (6/100,000 vs. 5/100,000).
Chevrolet pays for scheduled maintenance on the Blazer for 2 years and 24,000 miles. Chevrolet will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Kia doesn’t pay scheduled maintenance for the Sorento.
There are almost 4 times as many Chevrolet dealers as there are Kia dealers, which makes it much easier should you ever need service under the Blazer’s warranty.
The Blazer’s standard 2.5 DOHC 4 cyl. produces 8 more horsepower (193 vs. 185) and 10 lbs.-ft. more torque (188 vs. 178) than the Sorento’s standard 2.4 DOHC 4 cyl. The Blazer’s optional 3.6 DOHC V6 produces 15 more horsepower (305 vs. 290) and 17 lbs.-ft. more torque (269 vs. 252) than the Sorento’s optional 3.3 DOHC V6.
On the EPA test cycle the Blazer FWD V6 gets better fuel mileage than the Sorento FWD V6 (20 city/26 hwy vs. 19 city/26 hwy).
An engine control system that can shut down half of the engine’s cylinders helps improve the Blazer V6’s fuel efficiency. The Sorento doesn’t offer a system that can shut down part of the engine.
In heavy traffic or at stoplights the Blazer’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 Sorento doesn’t offer an automatic engine start/stop system.
The Blazer AWD’s standard fuel tank has 2.9 gallons more fuel capacity than the Sorento (21.7 vs. 18.8 gallons).
The Blazer 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 Sorento doesn’t offer a cap-less fueling system.
A nine-speed automatic is standard on the Chevrolet Blazer, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Sorento.
For better traction, the Blazer RS/Premier’s optional tires are larger than the largest tires available on the Sorento (265/45R21 vs. 235/65R17).
The Blazer RS/Premier’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Sorento SX/SXL’s 55 series tires.
For better ride, handling and brake cooling the Blazer has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Sorento L/LX. The Blazer RS/Premier’s optional 21-inch wheels are larger than the 19-inch wheels on the Sorento SX/SXL.
The Chevrolet Blazer’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Kia Sorento only has 5 wheel lugs per wheel.
The Blazer has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Sorento doesn’t offer vehicle monitored tire inflation.
For a smoother ride and more stable handling, the Blazer’s wheelbase is 3.3 inches longer than on the Sorento (112.7 inches vs. 109.4 inches).
For better handling and stability, the track (width between the wheels) on the Blazer is 2.2 inches wider in the front and 1.6 inches wider in the rear than the average track on the Sorento.
The front grille of the Blazer uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Sorento doesn’t offer active grille shutters.
The Blazer uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Sorento doesn’t offer active noise cancellation.
The Blazer has .3 inches more front headroom, .2 inches more rear legroom and .6 inches more rear shoulder room than the Sorento.
The Blazer has a much larger cargo volume than the Sorento with its rear seat up (30.5 vs. 11.3 cubic feet).
The Blazer’s front and rear power windows all lower 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 Sorento’s standard power windows’ passenger windows don’t open automatically.
On a hot day the Blazer’s driver can lower all the windows from a distance using the keyless remote. The driver of the Sorento can only operate the windows from inside the vehicle, with the ignition on.
The Blazer’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Sorento doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.
The Blazer 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 Sorento offers an automatic rear view mirror, but its side mirrors don’t dim.
The Blazer has a 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. Dual zone air conditioning costs extra on the Sorento and isn’t available on the Sorento L.
The Blazer’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Sorento L doesn’t offer automatic air conditioning.
The Blazer (except L)’s available 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 Sorento’s navigation system doesn’t offer real-time traffic updates.
