While the general public might have its issues with modern electric vehicles–range anxiety, charging infrastructure, and the mining of lithium for the batteries among them – gearheads who aren’t blind to the potential of all that torque right off the line seem to have one concern above all of those: Can EVs be hot-rodded and made to perform better? As with any vehicle, regardless of the energy source that turns the wheels, of course they can, but it’s the tradeoffs to watch out for.
As the Specialty Equipment Market Association recently noted, the EV aftermarket has steadily grown over the last few years, to the point where SEMA Electrified, a sort of show-within-a-show at the annual SEMA Show in Las Vegas, now features several dozen exhibitors across 21,000 square feet of the convention center floor. “Many folks who were new to the electric market were both surprised and excited to see how far this segment of the industry had progressed,” said Luis Morales, SEMA’s director of vehicle technology.
One SEMA Electrified exhibitor, Neil Tjin, likened the growing EV aftermarket to an earlier scene that rapidly took off. “I feel like where we were in the Nineties with Hondas and four-bangers and all that,” he said. “It’s all still so new that I heard so many questions about batteries, wiring, and what the EV motors will fit in.”
He noted that when he took a customized Ford Mustang Mach-E to SEMA in 2021, EVs still felt too new for the aftermarket crowd, but that changed last year when he displayed his customized Ford Lightning. “People are getting more used to EVs there,” he said.
How are EVs being modded?
If the exhibitors in the SEMA Electrified display are any indication of overall trends in the EV aftermarket scene, then a significant portion of that scene is dedicated to electromodding older vehicles either via individual components such as motors and controllers, conversion kits, or conversion services offering turnkey vehicles. One exhibitor, Switch Vehicles, even built an entire EV kit car from the ground up during the weeklong SEMA show.
For newer EVs, however, exhibitors focused more on charging solutions, service equipment, testing equipment, safety tools, and accessories. Tjin’s Lightning is a good example of the focus on accessories: The brand-new truck with less than 100 miles on it was painted green and fitted with a Ford accessory electronic bed cover, a custom grille and headlamps, Air Design roof and bed spoilers, a Thule bike rack and awning, Recaro seats, ARB air compressor, PowerTank air compressor, an electric grill, and even an ARB refrigerator and freezer. Underneath, Tjin had Baer six-piston front and rear brakes installed along with a Custom Air Lift suspension to drop the pickup over its 24-inch Vossen wheels and 295/45-24 Nitto Recon Grappler AT tires. The idea, Tjin said, was to build “the ultimate EV vehicle that does it all.”
Similarly, a scan of the leading Tesla aftermarket parts sources shows that hard parts for Teslas – beyond carbon-fiber trim pieces and other dress-up or utility accessories – are largely relegated to brake kits and suspension packages. The Nissan Leaf – at one point the all-time top-selling electric vehicle and a car that benefits from parts-bin sharing with other Nissan vehicles – sees little aftermarket support beyond floormats and charging adapters.
Wrenching, coding, or both?
Nevertheless, DIYers are beginning to find ways to juice the drivetrains of the EVs that have his the market over the last dozen years or so. Daniel Öster, better known as Dala from the YouTube channel Dala’s EV Repair, is one example. After a series of higher-capacity battery upgrades on Nissan Leafs, BMW i3s, and other EVs, he started to explore inverter swaps as a way of extracting more power out of older 80kW (110hp) Leaf drivetrains. The physical aspect of the swap is simple, with inverters from later Leafs bolting directly in place of their earlier counterparts, though the coding necessary to unlock the newer inverters’ full potential can be daunting. Still, the results are nothing to sneeze at, with output of up to 160 kilowatts (215 horsepower) possible. Öster discovered that even a 110kW (148hp) inverter swap cuts roughly a second and a half off of a Leaf’s 0-60 time.
Component upgrades like Öster’s inverter swap aren’t the only way for hotrodders to modify an EV for power and speed. Companies like Ingenext offer products like the Ghost that Öster describes as “man-in-the-middle CAN attack messages,” while other EVs like the Volkswagen eGolf can output more power with re-flashed computers.
One could also just pay for increased performance via a touchscreen. Tesla offers performance upgrades via software upgrades enabled by over-the-air updates and purchases. The Acceleration Boost upgrade, for instance, drops a Model 3’s 0-60 time from 4.2 to 3.7 seconds and costs $2,000. Dodge’s Tim Kuniskis has said that the brand will similarly offer tiered over-the-air performance upgrades for its upcoming performance EV and that the upgrades will be tied to the car’s VIN in an effort to lock out third-party tuners.
So what are the drawbacks?
Range, mainly. “Your battery might run out quicker due to all the improved acceleration and burnouts,” Öster noted.
Even Tjin, who left the drivetrains and electrical systems on both his Lightning and Mach-E entirely stock, has had to contend with reduced range due to his modifications. On the drive back home from SEMA, the 300-mile range that he anticipated from a perfectly stock Lightning (the EPA rates the Lightning’s range at 230 miles with the standard battery pack and 320 miles with the extended range battery pack) dwindled to 170 miles from a full charge thanks to the extra 1,000 pounds of accessories and the larger wheels and tires. He’s since shed a number of accessories from its display state so that it’s only carrying an additional 500 pounds or so and has seen the truck’s range on a full charge increase to about 250 miles. “It’s not terrible,” he said. “But the wheels and the weight do play a factor.”
Despite his likening it to the Nineties import tuner scene, Tjin said he sees EVs taking a different trajectory. “I see EVs right now as wheels, tires, sublte upgrades, maybe a wrap, but as builders, owners, shops and manufactures get more educated on EVs, I see them becoming more full builds,” he said. “The EV space also offers something different than the ’90s, because a lot of old school cars are undergoing EV swaps, which will give the EV space a huge demographic of builders and cars.”
Öster hasn’t discussed specific range limitations due to his modifications, but then again, he’s also upgraded from the stock 24 kWh battery to a later 62kWh unit and has started to explore how to adapt the Leaf’s original CHAdeMO fast charger with the increasingly more common CCS type fast charger using i3 components.
Indeed, maybe the future of EV modification isn’t as focused on power and speed as it is on extending range and adapting newer EV technology to older cars. After all, maybe all that torque right off the line is enough.
