To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-70. But it costs extra on the RX.

When descending a steep, off-road slope, the CX-70’s standard Hill Descent Control allows you to creep down safely. The RX doesn’t offer Hill Descent Control.

Both the CX-70 and the RX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

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 and into a post at 20 MPH, results indicate that the Mazda CX-70 is safer than the Lexus RX:

	CX-70	RX
	Front Seat

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 CX-70 is 1.4% to 2.8% less likely to roll over than the RX.

The Mazda CX-70 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The RX is not even a standard “Top Safety Pick” for 2025.

Warranty

There are over 2 times as many Mazda dealers as there are Lexus dealers, which makes it much easier should you ever need service under the CX-70’s warranty.

Engine

The CX-70 has more powerful engines than the RX:

	Horsepower	Torque
CX-70 3.3 turbo 6-cylinder hybrid	280 HP	332 lbs.-ft.
CX-70 PHEV 2.5 DOHC 4-cylinder hybrid	323 HP	369 lbs.-ft.
CX-70 Turbo S 3.3 turbo 6-cylinder hybrid	340 HP	369 lbs.-ft.
RX 350h 2.5 DOHC 4-cylinder hybrid	246 HP	233 lbs.-ft.
RX 350 2.4 turbo 4-cylinder	275 HP	317 lbs.-ft.
RX 450h+ Luxury 2.5 DOHC 4-cylinder hybrid	304 HP

As tested in Motor Trend the CX-70 PHEV 2.5 DOHC 4-cylinder hybrid is faster than the RX 350 2.4 turbo 4-cylinder:

	CX-70	RX
Zero to 60 MPH	6 sec	7.6 sec
Quarter Mile	14.4 sec	15.8 sec
Speed in 1/4 Mile	97.1 MPH	89.9 MPH

Fuel Economy and Range

On the EPA test cycle the CX-70 running its gasoline engine gets better mileage than the RX running its gasoline engine:

			MPG
CX-70
	AWD	3.3 turbo 6-cyl. Hybrid	24 city/28 hwy
		Turbo S 3.3 turbo 6-cyl. Hybrid	23 city/28 hwy
		2.5 4-cyl. Hybrid	24 city/27 hwy
RX
	FWD	350 2.4 turbo 4-cyl.	22 city/29 hwy
	AWD	350 2.4 turbo 4-cyl.	21 city/28 hwy

Both the CX-70 and the RX have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All CX-70s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The RX 350h/500h doesn’t offer a way to disable start/stop.

To lower fuel costs and make buying fuel easier, the Mazda CX-70 uses regular unleaded gasoline (premium recommended on CX-70 PHEV for maximum performance). The RX 350 requires premium, which can cost on average about 84.9 cents more per gallon.

The CX-70’s standard fuel tank has 4 gallons more fuel capacity than the RX 450+’s standard fuel tank (18.5 vs. 14.5 gallons), for longer range between fill-ups. The CX-70’s standard fuel tank has 1.3 gallons more fuel capacity than the RX 350h/500h’s standard fuel tank (18.5 vs. 17.2 gallons). The CX-70 Turbo S’ standard fuel tank has 1.8 gallons more fuel capacity than the RX 350’s standard fuel tank (19.6 vs. 17.8 gallons).

Brakes and Stopping

The CX-70 stops much shorter than the RX:

	CX-70	RX
70 to 0 MPH	171 feet	195 feet	Car and Driver
60 to 0 MPH	111 feet	139 feet	Motor Trend

Tires and Wheels

For better traction, the CX-70 has larger standard tires than the RX (265/55R19 vs. 235/60R19). The CX-70 Premium’s tires are larger than the largest tires available on the RX (275/45R21 vs. 235/60R19).

The CX-70’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 RX’s standard 60 series tires. The CX-70 Premium’s tires have a lower 45 series profile than the RX’s optional 50 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the CX-70’s wheelbase is 10.6 inches longer than on the RX (122.8 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the CX-70 is 1.9 inches wider in the front and .7 inches wider in the rear than on the RX.

The CX-70 Turbo S Premium handles at .86 G’s, while the RX 500h F Sport Performance pulls only .80 G’s of cornering force in a Car and Driver skidpad test.

The CX-70 PHEV Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the RX 350h (26.9 seconds @ .66 average G’s vs. 28.6 seconds @ .57 average G’s).

Passenger Space

The CX-70 has .2 inches more front headroom, .6 inches more front legroom, 1.1 inches more front shoulder room, .7 inches more rear headroom, 2 inches more rear legroom and 1.6 inches more rear shoulder room than the RX.

Cargo Capacity

The CX-70 has a much larger cargo volume with its rear seat up than the RX with its rear seat up (39.6 vs. 29.6 cubic feet). The CX-70 has a much larger cargo volume with its rear seat folded than the RX with its rear seat folded (75.3 vs. 46.2 cubic feet).

The CX-70’s cargo area is larger than the RX’s in almost every dimension:

	CX-70	RX
Length to seat (2nd/1st)	50.1”/97.5”	40”/76.2”
Max Width	49.8”	55.5”
Min Width	43.7”	42”
Height	31.6”	30”

Towing

The CX-70’s standard towing capacity is much higher than the RX’s (3500 vs. 0 pounds). Maximum trailer towing in the Lexus RX is only 3500 pounds. The CX-70 offers up to a 5000 lbs. towing capacity.

Servicing Ease

The engine in the CX-70 is mounted longitudinally (North-South), instead of sideways, as in the RX. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

Manual rear side window sunshades are available in the CX-70 to help block heat and glare for the rear passengers. The RX doesn’t offer rear side window sunshades.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mazda CX-70 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the RX.
