Safety

Both the RDX and the Blazer 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 all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Pick Plus” for 2019, a rating granted to only 36 vehicles tested by the IIHS. The Blazer has not been tested, yet.

Warranty

The RDX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Blazer’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Acura’s powertrain warranty covers the RDX 1 year and 10,000 miles longer than Chevrolet covers the Blazer. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Blazer ends after only 5 years or 60,000 miles.

The RDX’s corrosion warranty is unlimited miles longer than the Blazer’s (unlimited vs. 100,000 miles).

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Acura vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Acura 10 places higher in reliability than Chevrolet.

The RDX’s 2.0 turbo 4 cyl. produces 79 more horsepower (272 vs. 193) and 92 lbs.-ft. more torque (280 vs. 188) than the Blazer’s standard 2.5 DOHC 4 cyl. The RDX’s 2.0 turbo 4 cyl. produces 11 lbs.-ft. more torque (280 vs. 269) than the Blazer’s optional 3.6 DOHC V6.

Transmission

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the Blazer.

Tires and Wheels

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Blazer’s standard 65 series tires. The RDX A-Spec’s tires have a lower 40 series profile than the Blazer RS/Premier’s optional 45 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Blazer.

Suspension and Handling

The RDX offers an optional 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 Blazer’s suspension doesn’t offer adjustable shock absorbers.

Chassis

The RDX is 4.6 inches shorter than the Blazer, making the RDX easier to handle, maneuver and park in tight spaces.

Passenger Space

The RDX has .6 inches more front legroom and .6 inches more front shoulder room than the Blazer.

Cargo Capacity

The RDX has a larger cargo volume with its rear seat up than the Blazer with its rear seat up (31.1 vs. 30.5 cubic feet). The RDX has a larger cargo volume with its rear seat folded than the Blazer with its rear seat folded (79.8 vs. 64.2 cubic feet).

Ergonomics

The RDX Advance has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Blazer doesn’t offer a heads-up display.

The RDX’s front and rear power windows all open or close 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 Blazer’s passenger windows don’t close automatically.

If the windows are left open on the RDX the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Blazer can only close the windows from inside the vehicle, with the ignition on.

The RDX’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Blazer’s manually variable intermittent wipers have to be constantly adjusted. The RDX Advance’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

When the RDX 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 Blazer’s mirrors don’t automatically adjust for backing.

Recommendations

The Car Book by Jack Gillis recommends the Acura RDX, based on economy, maintenance, safety and complaint levels.
