Compact EV-specific transmission supports niche OEMs as they shift to electric

Following the recent release of its HPD E crate motors and associated kit to electrify the classic Mini, Swindon Powertrain is now extending its electrification range with a new standalone E-Transmission for EVs. Swindon says the single-speed gearbox is an affordable plug-and-play solution to purchasing a transmission to work with existing electric motors.

With two ratio options and multiple mounting points for ease of installation, the E-Transmission is designed for a range of vehicles, from kit and classic cars to light commercial vehicles. As a derivative of its HPD crate motor, Swindon offers retail pricing of £2,500. Trade customers seeking volume quantities can contact Swindon for pricing.

Designers specified a flanged e-motor adaptor plate design, facilitating the mounting to a wide range of electric motors, not just Swindon’s. Standard automotive driveshaft joint flanges facilitate external drive integration. Swindon says the OE-specification helical gears offer low levels of noise, vibration and harshness. A passive lubrication system minimizes complexity, cost and power losses and will perform without needing an oil pump. The E-Transmission weighs 17.9 kg and measures 250 x 384 x 228 mm.

“Since launching the HPD E Powertrain products, we have been inundated with customer inquiries from around the globe, and with each inquiry, we gain further insight into the needs and requirements of the end consumer,” said Swindon Director Gérry Hughes. “Adding the E-Transmission to our expanding range of electrification products provides our customers with the ultimate flexibility when it comes to converting or building their EVs. They can buy an entire system or select just the parts they need.”
