Compare the2023 Ford Mustang Mach-EVS 2022 Rivian R1S

The Mustang Mach-E has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R1S 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.

Over 200 people are killed each year when backed over by motor vehicles. The Mustang Mach-E has a standard Reverse Brake Assist that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The R1S doesn’t offer backup collision prevention brakes.

Both the Mustang Mach-E and the R1S have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

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 vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Mustang Mach-E the rating of “Top Safety Pick” for 2022, a rating granted to only 175 vehicles tested by the IIHS. The R1S has not been tested, yet.

On the EPA test cycle the Mustang Mach-E gets better mileage than the R1S:

The Mustang Mach-E ER RWD can travel longer on a full charge than the R1S Dual Motor Standard (310 miles vs. 260 miles).

For better stopping power the Mustang Mach-E’s front brake rotors are larger than those on the R1S:

The Mustang Mach-E stops much shorter than the R1S:

The Mustang Mach-E GT handles at .92 G’s, while the R1S 4dr Sport Utility pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The Ford Mustang Mach-E may be more efficient, handle and accelerate better because it weighs about 1450 to 2000 pounds less than the Rivian R1S.

The Mustang Mach-E is 1 foot, 3.2 inches shorter than the R1S, making the Mustang Mach-E easier to handle, maneuver and park in tight spaces.

The Mustang Mach-E is 7.7 inches narrower than the R1S, making the Mustang Mach-E easier to handle and maneuver in traffic.

The Mustang Mach-E is 13.9 inches shorter in height than the R1S, making the Mustang Mach-E much easier to wash and garage and drive (lower center of gravity).

The Mustang Mach-E has a much larger cargo volume than the R1S 4dr Sport Utility with its rear seat up (34.4 vs. 17.6 cubic feet).

The Mustang Mach-E’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The R1S’ tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

To make loading groceries and cargo easier when your hands are full, the Mustang Mach-E’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The R1S doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

The Mustang Mach-E has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The R1S doesn’t offer a remote starting system.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Mustang Mach-E’s exterior PIN entry system. The R1S doesn’t offer an exterior PIN entry system.

The Mustang Mach-E’s standard 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 R1S’ available navigation system doesn’t offer real-time traffic updates.

The Mustang Mach-E’s optional Active Park Assist 2.0 can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The R1S doesn’t offer an automated parking system.

The Mustang Mach-E is available in both rear-wheel drive and four-wheel drive configurations. The R1S doesn’t offer a two-wheel drive configuration.

A group of representative automotive journalists from North America selected the Mustang Mach-E as the 2021 North American Utility Vehicle of the Year. The R1S has never been chosen.
