Historically, hybrids and electric cars have hardly been the stuff of custom car dreams, but that’s starting to change as cities around the world threaten to ban combustion engines, a trend that has pushed electrified vehicles closer to the mainstream and into the consciousness of car tuners.

The latest eco-friendly car to get a custom treatment is Hyundai’s Ioniq, which California tuning shop Bisimoto has turned into the HyperEconiq Ioniq, a creation Bisimoto and Hyundai will display later this month at the Specialty Equipment Market Association (SEMA) show in Las Vegas.

Bisimoto is a shop that, according to its website, will modify anything from vintage Porsche 911s to Honda Odyssey minivans and, seemingly, anything in between: the HyperEconiq Ioniq started out as the hybrid version of Hyundai’s Ioniq, a compact hatchback you can currently also buy as a full EV and that will soon be offered with a plug-in hybrid powertrain.

The Ioniq is certainly not a sports car, and Bisimoto wasn’t interested in turning it into one. Instead, it crafted modifications mostly focused on making the car ever more fuel-efficient.

Among those mods is a pulse wave exhaust that, thanks to a whole lot of science we don’t really understand, Bisimoto says optimizes the pressure pulses expelled from the engine to help pull more air into the combustion chamber and improve performance.

Other performance-related changes include “bespoke” low-friction motor oil for the Ioniq’s 1.6-litre engine, low-rolling-resistance tires on 19-inch wheels, better spark plugs and enhanced e-generators (which we assume means Bisimoto has modified the Ioniq’s regenerative braking system).

There’s also a custom body kit to improve the car’s aerodynamics, which are also aided by a set of lowering springs to reduce ground clearance and aerodynamic drag.

Bisimoto said its modifications have resulted in fuel economy of “well over 80 MPG (US),” which works out to just under 3.0 L/100 km, while an Ioniq Hybrid in its factory form promises fuel consumption as low as 4.0 L/100 km.

This year’s SEMA show runs from October 31 to November 3 in Las Vegas, Nevada.
