Safety

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 RDX doesn’t offer a back seat reminder.

Both the Blazer and the RDX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The Blazer’s corrosion warranty is 1 year longer than the RDX’s (6 vs. 5 years).

Chevrolet pays for the first scheduled maintenance on the Blazer. Chevrolet will pay for the first oil change, lubrication and any other required maintenance in the first year. Acura doesn’t pay scheduled maintenance for the RDX.

There are over 11 times as many Chevrolet dealers as there are Acura dealers, which makes it much easier should you ever need service under the Blazer’s warranty.

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Acura vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 17 more problems per 100 vehicles, Acura is ranked 20th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than Acura vehicles. J.D. Power ranks Chevrolet 6th in reliability, above the industry average. With 35 more problems per 100 vehicles, Acura is ranked 20th.

Engine

The Blazer’s optional 3.6 DOHC V6 produces 33 more horsepower (305 vs. 272) than the RDX’s 2.0 turbo 4 cyl.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Blazer V6’s fuel efficiency. The RDX doesn’t offer a system that can shut down part of the engine.

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

The Blazer FWD’s standard fuel tank has 2.3 gallons more fuel capacity than the RDX (19.4 vs. 17.1 gallons), for longer range between fill-ups. The Blazer AWD’s standard fuel tank has 4.6 gallons more fuel capacity than the RDX (21.7 vs. 17.1 gallons).

Brakes and Stopping

For better stopping power the Blazer’s brake rotors are larger than those on the RDX:

Tires and Wheels

For better traction, the Blazer RS/Premier’s optional tires are larger than the largest tires available on the RDX (265/45R21 vs. 255/40R20).

For better ride, handling and brake cooling the Blazer RS/Premier offers optional 21-inch wheels. The RDX’s largest wheels are only 20-inches.

The Chevrolet Blazer’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Acura RDX only has 5 wheel lugs per wheel.

Suspension and Handling

For a smoother ride and more stable handling, the Blazer’s wheelbase is 4.4 inches longer than on the RDX (112.7 inches vs. 108.3 inches).

For better handling and stability, the track (width between the wheels) on the Blazer is 2.2 inches wider in the front and 1.5 inches wider in the rear than on the RDX.

Chassis

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 RDX doesn’t offer active grille shutters.

Passenger Space

The Blazer has 3.8 cubic feet more passenger volume than the RDX (107.8 vs. 104).

The Blazer has .2 inches more front headroom, .6 inches more front hip room, .3 inches more rear headroom, 1.2 inches more rear legroom, 4.3 inches more rear hip room and 2 inches more rear shoulder room than the RDX.

Towing

Maximum trailer towing in the Acura RDX is limited to 1500 pounds. The Blazer offers up to a 4500 lbs. towing capacity.

Ergonomics

The Blazer (except L) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The RDX doesn’t offer a house-current electrical outlet.
