May/June 2023 | E-Mobility Engineering 21 an original EV design, and in particular to bring a low-volume electrified ‘halo’ platform to life,” says Paul McNamara, technical director at WAE. The term ‘halo’ in this instance refers typically to limited-edition showstopper vehicles that some manufacturers will unveil to grab the attention of the automotive media and enthusiasts. “The problem that all of them find is that the development costs of producing that initial EV are highly uneconomical, particularly for a low-volume product,” McNamara says. “Knowing that, along with our background in high-performance motorsport, we felt we could put something together that would serve this new generation of start-up OEMs, as a practical way for them to start on their low-volume sports EVs.” From that came the EVR, a highly modular skateboard EV platform optimised for headline-grabbing electric supercars. The systemwas unveiled to the public for the first time at LCV- Cenex at Millbrook, England, in 2022. In its baseline configuration it features an 85 kWh battery that can be DC fast- charged from empty to full SoC in just under 20 minutes, and provides a range of just over 450 km between charges. Also, its powertrain is engineered for a maximum power output of 1650 kW, enough to enable a top speed of just over 400 kph and acceleration from system intended for integration with conventional passenger car designs. It features a novel carbon composite chassis, with each cell in its lithium-ion battery being wrapped in a carbon fibre box, as well asWAE’s patented Racetrak carbon fibre wishbone suspension. In addition to the EVX and related projects, WAE has alsoworked on a number of two-seater sportscars over the past several years, including the C-X75 HEV fromJaguar and the all-electric Nissan Bladeglider proof of concept. “Those kinds of projects and EV configurations led us to talking with a lot of prospective customers in the smaller, more of a start-up domain, who were looking to start manufacturing Dossier | WAE EVR WAE’s EVR skateboard is designed for OEMs building limited-edition electric sportscars.
