Add or Delete These Simple Parts to Help Customers Save Money

Looking for an easy way to win over your customers that they’ll enjoy every time they drive? Look at their vehicles from a hypermiler’s perspective.

In case you haven’t heard the term before, the hypermiling community is obsessed with optimizing their vehicles’ fuel economy. This world of homemade streamliners may not be mainstream, but the primary goal of minimizing fuel/charge consumption is appealing to any customer dropping a daily driver off at your shop.

Look at this this way: If your drive to work could cost three to five percent less for a small price or maybe none at all, why wouldn’t you make those changes? Many of your customers might not have the skills or ability to improve their vehicle’s efficiency. They might not even realize that small modifications or missing parts can have a profound impact on fuel economy. Best of all, they don’t have to take your word for it. A simple before/after comparison of the vehicle’s fuel economy average should be plenty to really impress your customers.

Note: Fuel economy and efficiency gains/losses vary wildly from one vehicle to another, as do the driving habits of “the nut behind the wheel.”

Parts to remove or delete for better fuel economy

When building a hypermiler, the first steps include dropping unnecessary weight, removing aerodynamic obstacles, and repairing or improving existing aerodynamic features. Let’s use the same approach here.

Remove: roof racks, cargo cages, and accessories

Roof racks are one of the best examples. Is it a roof rack on a work truck that’s absolutely beat from hauling ladders, or a scraped-up kayak hauler on a muddy SUV? Those roof racks are earning their keep and can stay. A mint factory rack on a grocery getter is another story. Inform your customers that roof racks can reduce a car or truck’s fuel economy by ten percent or more, and the cost gets even worse if accessories like cargo cages or bicycle carriers are left installed all the time. Offer to remove the unused rack, and both you and your customer should feel like you’ve made the smart move.

Remove: light bars

Another popular accessory for SUVs, trucks, and outdoorsy types, the thin LED light bars seen on many vehicles today have a lower profile than the KC Daylighter-style auxiliary lights of old. Light bars can still introduce a lot of drag, however, especially when mounted above the windshield or up on the hood. If a customer isn’t using their light bar for much, changing to smaller and better-integrated LED lights, such as a pair of flush-mounts in the bumper, can help both fuel economy and cabin noise without too much time or cost.

Add or repair: Missing or damaged factory aero parts

It’s not uncommon for parts like splash guards and front splitters to break or fall off. They don’t make a big visual impact, and in some cases, your customer might not even realize that they are missing. So why worry?

Missing or damaged panels and trim, especially undercar shields, aren’t just for keeping splashes and debris out of the engine bay and undercarriage. Today’s vehicles are designed with careful aerodynamic testing, and removing any component from the original system can affect fuel economy. A missing or broken panel can also reduce airflow across critical heat exchangers, like condensers, radiators, and transmission coolers. Often, a few fresh body fasteners are all you’ll need to tidy up a sagging shield.

Add or repair: Broken or missing tailgates

At this point, I think every mechanic has heard about how a pickup truck is significantly more aerodynamic with its tailgate up, not down. But have your customers heard this? When a truck is missing its tailgate, or the latch mechanism has failed so that the gate won’t stay secured upright, point this out to your customer. A busted gate isn’t just inconvenient. It’s adding unnecessary cost to every mile driven, and repairs are typically straightforward and inexpensive.

Add or repair: Wheel covers

For hybrids and EVs in particular, the factory wheel covers aren’t just there for looks. A set of four missing wheel covers can reduce range per charge by up to ten miles on a modern EV. Unless the covers have been removed intentionally, reinstalling a set of original pattern wheel covers is an affordable way to combat range anxiety.

Any one of these changes will help, but keep in mind that the effect is cumulative. More importantly, your customers will leave with the confidence that you are looking out for their vehicles … and their wallets.
