The Mazda CX-70 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Envision doesn’t offer a front passenger side knee airbag.

The CX-70 Premium has a standard Secondary Collision Reduction System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Envision doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The CX-70’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 Envision doesn’t offer a driver alert monitor.

Both the CX-70 and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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 and available around view monitors.

The Mazda CX-70 weighs 778 to 1294 pounds more than the Buick Envision. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

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 Buick Envision:

	CX-70	Envision
	Front Seat
STARS	5 Stars	5 Stars
HIC	53	128
Chest Movement	.6 inches	.7 inches
Abdominal Force	137 lbs.	139 lbs.
Hip Force	174 lbs.	261 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	21	311
Spine Acceleration	27 G’s	52 G’s
Hip Force	416 lbs.	572 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	15 inches
Spine Acceleration	31 G’s	36 G’s

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% less likely to roll over than the Envision.

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 Envision has not yet been evaluated by the IIHS for 2025.

Warranty

The CX-70’s corrosion warranty is unlimited miles longer than the Envision’s (unlimited vs. 100,000 miles).

Reliability

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Mazda vehicles are more reliable than Buick vehicles. Consumer Reports ranks Mazda 5 places higher in reliability than Buick.

Engine

The CX-70’s standard 3.3 turbo 6-cylinder hybrid produces 52 more horsepower (280 vs. 228) and 74 lbs.-ft. more torque (332 vs. 258) than the Envision’s 2.0 turbo 4-cylinder. The CX-70 PHEV’s standard 2.5 DOHC 4-cylinder hybrid produces 95 more horsepower (323 vs. 228) and 111 lbs.-ft. more torque (369 vs. 258) than the Envision’s 2.0 turbo 4-cylinder. The CX-70 Turbo S’ standard 3.3 turbo 6-cylinder hybrid produces 112 more horsepower (340 vs. 228) and 111 lbs.-ft. more torque (369 vs. 258) than the Envision’s 2.0 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the CX-70 PHEV running on electricity gets better mileage than the Envision (53 city/61 hwy MPGe vs. 22 city/28 hwy).

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

			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
Envision
	AWD	2.0 turbo 4-cyl.	22 city/28 hwy

The CX-70 PHEV can travel with zero emissions for 26 miles. The Envision can’t move without running its internal combustion engine.

Regenerative brakes improve the CX-70’s fuel efficiency by converting inertia back into energy instead of wasting it. The Envision doesn’t offer a regenerative braking system.

The CX-70’s standard fuel tank has 2.4 gallons more fuel capacity than the Envision (18.5 vs. 16.1 gallons), for longer range between fill-ups. The CX-70 Turbo S’ standard fuel tank has 3.5 gallons more fuel capacity than the Envision (19.6 vs. 16.1 gallons).

The CX-70 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Envision. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

For better stopping power the CX-70’s brake rotors are larger than those on the Envision:

	CX-70	CX-70 Turbo S/PHEV	Envision
Front Rotors	12.9 inches	13.7 inches	12.6 inches
Rear Rotors	13.8 inches	13.8 inches	12.4 inches

Tires and Wheels

For better traction, the CX-70 has larger standard tires than the Envision (265/55R19 vs. 235/60R18). The CX-70 Premium’s tires are larger than the largest tires available on the Envision (275/45R21 vs. 245/45R20).

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 Envision Preferred’s standard 60 series tires.

For better ride, handling and brake cooling the CX-70 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Envision Preferred. The CX-70 Premium’s 21-inch wheels are larger than the 20-inch wheels on the Envision Sport Touring/Avenir.

Suspension and Handling

The CX-70 has variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Envision doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the CX-70’s wheelbase is 13.4 inches longer than on the Envision (122.8 inches vs. 109.4 inches).

For better handling and stability, the track (width between the wheels) on the CX-70 is 3.8 inches wider in the front and 3.9 inches wider in the rear than on the Envision.

Passenger Space

The CX-70 has 41.2 cubic feet more passenger volume than the Envision (141.6 vs. 100.4).

The CX-70 has .1 inches more front headroom, 1.3 inches more front legroom, 1.1 inches more front hip room, 2.5 inches more front shoulder room, .4 inches more rear headroom, .1 inches more rear legroom, 8.1 inches more rear hip room and 2.2 inches more rear shoulder room than the Envision.

For enhanced passenger comfort on long trips the CX-70’s rear seats recline. The Envision’s rear seats don’t recline.

Cargo Capacity

The CX-70 has a much larger cargo volume with its rear seat up than the Envision with its rear seat up (39.6 vs. 25.2 cubic feet). The CX-70 has a much larger cargo volume with its rear seat folded than the Envision with its rear seat folded (75.3 vs. 52.7 cubic feet).

Pressing a button automatically lowers the CX-70’s rear seats, to make changing between passengers and cargo easier. The Envision doesn’t offer automatic folding seats.

Towing

The CX-70’s standard towing capacity is much higher than the Envision’s (3500 vs. 1500 pounds). Maximum trailer towing in the Buick Envision is only 1500 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 Envision. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The CX-70’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 Envision’s rear power window switches have to be held the entire time to close them fully.

The CX-70’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Envision’s standard manually variable intermittent wipers have to be constantly adjusted.

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

Both the Mazda CX-70 and Buick Envision offer exterior mirrors that can be folded to provide convenience. The CX-70 offers available power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Envision’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The CX-70 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 Envision.
