How to Choose the Best Tonneau Cover for Gas Mileage Improvement
Hard vs. Soft Covers for Aerodynamics
Hard tonneau covers generally provide better aerodynamic performance than soft covers because they create a smoother, more rigid surface. The solid construction prevents the cover from flapping or billowing at high speeds, which maintains consistent airflow.
Soft covers can still improve fuel efficiency by 3-5%, but hard covers typically deliver 5-10% improvements. If maximum fuel savings is your priority, invest in a hard cover with a low-profile design.
Consider your budget and how often you need bed access when choosing between hard and soft options. Hard covers cost more but last longer and provide better long-term fuel savings.
Cover Profile and Design
Low-profile covers that sit flush with your truck’s cab create the best aerodynamic performance. These designs minimize the air gap between the cab and cover, reducing turbulence and drag.
Look for covers with smooth, continuous surfaces rather than bulky designs with protruding hardware. The sleeker the profile, the better your fuel efficiency improvements will be.
Tri-fold and roll-up designs both work well, but ensure the cover lays completely flat when closed. Any wrinkles, gaps, or raised sections will increase wind resistance and reduce fuel savings.
Material Quality and Weight
Lightweight materials like fiberglass reinforced polymer (FRP) or marine-grade vinyl provide good aerodynamics without adding excessive weight to your truck. Heavy covers can actually hurt fuel efficiency by increasing your vehicle’s overall weight.
Choose materials that resist weathering and maintain their shape over time. Covers that sag or warp will lose their aerodynamic benefits and may actually increase drag.
Aluminum frames and honeycomb internal structures offer the best strength-to-weight ratio for hard covers. For soft covers, look for heavy-duty vinyl (24oz or higher) with sturdy crossbars.
Weather Sealing and Fit
Proper weather sealing prevents air from getting under your cover, which maintains aerodynamic efficiency. Look for covers with quality seals along all edges and at the tailgate.
A custom-fit cover designed specifically for your truck model will always perform better than universal-fit options. The tighter the fit, the less air turbulence you’ll create.
Check that the cover sits flush against your truck bed rails without gaps. Even small openings can create air pockets that increase drag and reduce your fuel savings.
Installation and Adjustability
No-drill installations are convenient and won’t void your truck’s warranty, but make sure the clamp system holds the cover securely. Loose covers that shift or vibrate will hurt aerodynamics and create noise.
Look for covers with tension adjustment systems that let you keep the surface tight in all weather conditions. Soft covers especially need proper tensioning to maintain their aerodynamic profile.
Consider how often you’ll need to remove or fold back the cover. Some designs offer better cargo access while maintaining fuel efficiency when closed.
Frequently Asked Questions
How much can a tonneau cover actually improve gas mileage?
Most tonneau covers improve fuel efficiency by 3-10% depending on the cover type and your driving conditions. Hard covers with low-profile designs typically deliver the best results, especially at highway speeds above 55 mph.
Do soft or hard tonneau covers save more gas?
Hard tonneau covers generally save more gas because they create a smoother, more rigid aerodynamic surface. Soft covers still help by reducing wind drag, but they can’t match the consistent performance of hard covers at high speeds.
Will a tonneau cover pay for itself in fuel savings?
A tonneau cover can pay for itself in 1-3 years depending on how much you drive and current gas prices. If you drive 15,000 miles annually with a 5% fuel efficiency improvement, you could save $200-400 per year on gas.
Does tonneau cover style matter for fuel efficiency?
Yes, cover style significantly impacts fuel efficiency. Low-profile hard covers that sit flush with the cab provide the best aerodynamics, while bulky or poorly-fitted covers may actually increase drag and hurt fuel economy.
Can I improve gas mileage with a roll-up tonneau cover?
Roll-up tonneau covers can improve gas mileage by 3-7% when properly tensioned and closed. Hard roll-up covers with aluminum slats perform better aerodynamically than soft vinyl roll-ups because they maintain a flatter, smoother surface.
Final Thoughts
The Tono King FRP Hard Folding Cover offers the best overall value for fuel efficiency at $399.99, while budget-conscious buyers should consider the Aurorasters Soft Tri-Fold at $199.99.
Choose a hard cover with a low profile if maximum fuel savings is your priority, but soft covers still deliver noticeable improvements at lower price points. Make sure the cover fits your specific truck model properly for the best aerodynamic performance.
Any quality tonneau cover will pay for itself through fuel savings over time, so pick one that matches your budget and cargo access needs.
