Best EV Cargo Accessories 2026: Trunk Organizers, Roof Racks & Frunk Mats

EVs have unique cargo spaces — flat trunk floors (no spare tire hump), front trunks (frunks), and in the case of SUVs like the Model Y and Rivian R1S, cavernous hatch areas. The right cargo accessories keep everything organized and protected.

Trunk Organizers

Best for Tesla Model Y/3: [Tesmanian Rear Trunk Organizer](#affiliate) (~$40)

Collapsible organizer with multiple compartments that fits perfectly in the Tesla trunk. Folds flat when not in use, which is important because EV trunks are not huge.

Best for Rivian R1T: [Rivian Gear Tunnel Crossbars + Bag](#affiliate) (~$350)

The R1T's gear tunnel is unique to Rivian and requires Rivian-specific accessories. The crossbar and bag system turns the gear tunnel into organized storage for camping gear, tools, and equipment.

Best Universal: [Drive Auto Trunk Organizer](#affiliate) (~$25)

If you want a simple, affordable organizer that works in any EV trunk, this collapsible box gets the job done. Multiple compartments, anti-slip bottom, folds flat when empty.

Frunk Mats

Most EVs have a front trunk (frunk) that collects dirt, leaves, and moisture. A dedicated frunk mat protects the cargo area and makes cleaning easy.

Tesla Model 3/Y: Tesmanian Frunk Mat (~$30) — custom-fit TPE mat with raised edges.

Tesla Model S/X: 3D MAXpider Frunk Mat (~$50) — premium fit for the larger frunk.

Rivian R1T/R1S: Rivian Shop Frunk Mat (~$45) — official Rivian accessory with perfect fit.

Ford Mustang Mach-E: WeatherTech Frunk Liner (~$55) — deep channels for the Mach-E's sizable frunk.

Roof Racks and Cargo Carriers

EVs with glass roofs (Tesla, Rivian) require roof rack systems designed specifically for their attachment points. Do not use universal clamp-on racks — they can damage the glass roof.

Best for Tesla: [Yakima BaseLine System](#affiliate) (~$350)

Clips to Tesla's factory mounting points without drilling or adhesive. Compatible with Yakima's full range of bike racks, ski carriers, and cargo boxes.

Best for Rivian: [Rivian Crossbars](#affiliate) (~$450)

Official Rivian crossbars mount to the factory roof rail tracks. Compatible with most aftermarket T-slot accessories.

Cargo Nets and Straps

A simple cargo net or strap system prevents groceries and gear from sliding around during driving. EVs have strong regenerative braking that can send unsecured items flying forward.

Our pick: Spidy Gear Trunk Cargo Net (~$15) — attaches to the trunk walls and holds items securely.

Buying Guide

EV-Specific vs Universal

Always prefer EV model-specific accessories when available. Universal organizers fit but leave gaps, and universal roof racks may not be compatible with glass roofs.

Weight Considerations

EVs are already heavy. Adding a loaded roof rack increases weight and decreases aerodynamic efficiency, reducing range by 5-15%. Use roof cargo only when needed.

FAQ

Do roof racks affect EV range? Yes. A roof rack alone reduces range by about 2-3%. Adding a cargo box or bikes can reduce range by 10-20% depending on speed and load.

Can I use the Tesla frunk for groceries? Absolutely. The frunk is perfect for groceries — it is separated from the cabin so smells do not transfer, and items stay cool in winter. A frunk mat makes cleanup easy.

What is the Rivian gear tunnel? The Rivian R1T has a pass-through storage compartment between the cab and truck bed. It is about 65 inches long and holds camping gear, fishing rods, or a small cooler. It is unique to the R1T and one of its best features.
