SEMA-bound Plymouth GTX Electromod teases EV conversion potential

• Plymouth GTX Electromod concept to debut at 2024 SEMA show
• Concept features electric crate motor rated at 335 hp
• Electric motor borrowed from 2024 Dodge Charger Daytona EV

The crate engines offered via Stellantis’ Mopar division are some of the best in the business, but in the near future buyers will likely have the additional option of an electric powertrain in crate form.

Stellantis will use the 2024 SEMA show on next week to preview just that future with a 1967 Plymouth GTX powered purely by batteries.

Stellantis calls the build the Plymouth GTX Electromod, and its powertrain, referred to as an e-Crate powertrain, consists of a single electric motor sitting up front on custom-designed isolated motor mounts, and driving the rear wheels via a 3:1 gear reducer and 8.75-inch rear axle. The motor is borrowed from the new 2024 Dodge Charger Daytona EV.

Peak power is approximately 335 hp here. The setup is designed to be scalable, meaning more power could have been installed, though this would have required reinforcing the body and frame. A Stellantis spokesman said that this wasn’t previewed on the concept because it is beyond the scope of the typical restomod project.

Four individual lithium-ion batteries are split three at the rear and one at the front for ideal weight distribution. Each weighs about 230 pounds and combines to deliver 73 kwh of capacity, or enough for around 250 miles of range, Stellantis estimates. The electrical system is rated at 400 volts but Stellantis hasn’t said at what charging rates the batteries will accept.

Stellantis also hasn’t said how quick the Plymouth GTX Electromod is, but said the concept has been tested at a speed of over 100 mph.

The design team also customized the rest of the vehicle, including installing some carbon-fiber pieces to help save weight. The interior has also been fitted with a custom instrument cluster containing analog gauges, plus readings for battery charge status and battery and motor temperatures. A rotary shift knob from the Dodge Durango was also installed for the gear selector.

Stellantis isn’t the only major automaker looking at offering electric crate motors. Ford and General Motors have also shown their own designs, while other automakers have teamed up with some aftermarket firms. Mini is also offering an EV conversion service for the original Issigonis-designed Mini at its factory in the U.K.
