Can you put a roof rack on an electric car?
Yes, you can mount a roof rack on most electric vehicles, but the setup depends on your model's roof design, mounting points, and the type of rack you choose. Some EVs come with factory rails, others have smooth roofs that require clamps or adapters. Always consult the owner's manual and follow manufacturer guidance.
Electric cars share the same cargo needs as gasoline cars — roof racks can expand storage for bikes, kayaks, luggage, and outdoor gear. However, adding a roof rack changes aerodynamics and can affect driving range, noise, and handling. This article explains how roof rack options apply to EVs, what to consider before buying, and how to install safely and efficiently.
Assessing your EV’s roof for a rack
Before choosing a rack, determine what your car provides on the roof and what it can support.
How roof design varies by model
Some electric cars come with factory roof rails or integrated crossbars, while others have a smooth, railless surface or a glass roof that complicates mounting. Checking the manual or with a dealership can clarify compatibility and weight limits.
- Factory-installed roof rails with crossbars
- Flush-mounted rails or integrated roof rails (no visible crossbars)
- Bare-roof with clamp-on crossbars that grip the door jambs or roof edge
- Roof-mounted cargo solutions that attach to existing structural points or mounting kits
Knowing your roof configuration helps you pick a rack system that fits securely and minimizes wind noise and drag.
Choosing the right rack for your EV
Consider these factors when selecting a roof rack system:
- Compatibility with your roof: rails, no-rail bare roof, sunroof interference
- Weight rating: ensure the rack and cargo stay within the vehicle’s roof loading limits
- Aerodynamics: low-profile crossbars reduce drag and noise
- Ease of installation and removal: quick-attach systems save time
- Warranty and vehicle compatibility: some EVs warn against certain aftermarket racks
Choosing the right combination helps maintain safety, efficiency, and warranty coverage while meeting your cargo needs.
Safety and installation tips
Follow these best practices to install a roof rack safely on an electric car:
- Consult the owner's manual for maximum roof weight and approved rack types.
- Measure crossbar width to fit your car’s roof and any sunroof or antennas.
- Distribute weight evenly across the roof and keep heavy items low and centered.
- Secure all gear firmly and check ties and clamps after driving a short distance.
- Avoid overtightening; check and re-torque as required by the rack instructions.
- Be mindful of parking clearances and garage doors to prevent damage.
- Remove the rack when not in use if it is not needed, to reduce drag and noise.
Always recheck fasteners after long trips or weather events and follow the rack manufacturer’s maintenance guidelines.
Impact on range and performance
Attaching a roof rack increases aerodynamic drag, which can reduce efficient energy use and driving range, particularly at highway speeds or with a fully loaded cargo box. The exact impact varies by vehicle, rack type, speed, and weather; many EV drivers notice a handful of percentage points drop in range when driving with a roof box at typical highway speeds, with smaller crossbars having a smaller effect. If range is critical, plan routes with charging stops and consider removing the rack when not in use.
Summary
In short, you can put a roof rack on most electric cars, but you should choose a system that matches your roof configuration, respects weight limits, and minimizes aerodynamic drag. With careful selection and proper installation, a roof rack can expand your EV’s carrying capacity without compromising safety or warranty.
