Elaphe and McLaren are partnering to marry the previous’s in-wheel motor tech with the latter’s racing experience.
On the latest 2023 CES in Las Vegas, the 2 corporations introduced an “in-wheel propulsion system” utilizing Elaphe’s in-wheel motors and inverters from McLaren Utilized Applied sciences to create “extremely environment friendly and hyper-responsive electrical automobiles,” in response to an Elaphe press launch.
Elaphe-developed in-wheel motors are on the core of among the most eagerly anticipated super-efficiency automobiles—like the upcoming Aptera. With in-wheel motors, Lightyear has claimed the best manufacturing powertrain on this planet for its Lightyear 0 solar-assisted EV.

Lordstown Motors in 2020 introduced a deal to license Elaphe’s in-wheel motor tech for its Endurance pickup truck. It nonetheless stands out as the one firm that’s utilizing in-wheel motors for a standard truck moderately than an efficiency-focused car just like the Aptera and Lightyear.
Points just like the added unsprung weight of a motor mounted within the wheel hub have restricted the variety of purposes for in-wheel motors, however Elaphe hopes the addition of the McLaren unit’s racing tech will assist broaden their enchantment.
McLaren Utilized Applied sciences has designed inverters for Components One and Components E, in addition to the McLaren P1 plug-in hybrid supercar that debuted in 2012, in response to Elaphe. McLaren additionally competes in F1 and (as of 2023) Components E as a manufacturing unit staff, however the racing, road-car, and applied-technologies divisions are all siloed throughout the firm.

The powertrain developed in partnership with Elaphe will use McLaren’s latest IPG5 inverter, an 800-volt silicon-carbide unit that may ship effectivity of as much as 99%, Elaphe claims, with the in-wheel motors themselves claimed to have demonstrated as much as 97% effectivity. Along with its motors, that can assist present “best-in-class long-range cruising effectivity and unmatched car controllability, with a torque response 5 instances quicker in comparison with present programs,” in response to the corporate.
This may not be the primary instance of racing expertise informing EV road-car improvement. Lucid’s battery division Atieva served with McLaren Utilized Applied sciences to energy Components E racing for a number of years, then utilized its Components E battery experience to the Air luxurious sedan.
