Williams Superior Engineering debuts ultra-high efficiency EV platform for hypercars; H2 variant underneath growth


Williams Superior Engineering (WAE) unveiled an ultra-high efficiency electrical car platform designed to speed up the ambitions of hypercar producers, from start-ups to OEMs.

The newest iteration of WAE EV platforms, EVR is concentrated on the rising electrical hypercar sector, with a light-weight composite construction that mounts the high-performance battery system in the midst of the car, optimising centre of gravity.

EVR can assist a spread of electrical hypercar configurations, from track-only automobiles the place power-to-weight is maximized, to roadgoing fashions, each open-roof Targa and fixed-roof GT architectures. That is made doable by the structure’s central tub which has been designed to permit for such flexibility, together with open roof design, whereas nonetheless that includes the very newest efficiency expertise akin to lively aerodynamics.


With a 85 kWh battery and peak energy of 1650 kW, EVR allows sub-2.0 secs 0-100 km/h acceleration and a high velocity greater than 400 km/h (248 mph) with a car mass lower than 1800 kg, together with fast-charging functionality of sub-20 minutes and a spread in extra of 450 km (279 miles). All-wheel drive and rear-wheel drive layouts are supported by way of a number of e-motor configurations.

For start-ups, EVR gives an entire turnkey answer, with WAE delivering the whole car, with exterior design assist equipped by the client or a WAE associate.


For OEMs, EVR accelerates path to market, with the whole engineering and meeting of the rolling chassis accomplished by WAE. Able to being tailored for each the OEM’s design and styling necessities, EVR reduces time from growth to market launch.

Equally, for OEMs and Tier 1s, EVR gives the chance to combine new merchandise to push the boundaries of electrical powertrain expertise, with the rolling chassis able to being repeatedly developed with WAE’s latest motor and battery applied sciences.

Engineered for max flexibility for buyer necessities, each by way of inside and exterior design, EVR ends in a decreased time to market with class-leading efficiency, with WAE focusing on supply of a primary EVR-based prototype inside 12 months from challenge kick-off to supply of a primary manufacturing car in 24 months.

EVR can be prepared for a hydrogen future with an EVR-H gas cell variant additionally being developed to ship the equal efficiency of a pure BEV platform however powered by inexperienced hydrogen.

Williams Superior Engineering additionally unveiled the Scalable Battery Module (SBM). Using WAE’s proprietary Sense Chain structure, the SBM system eliminates the replication of electronics, whereas enabling unbiased scaling of voltage and capability and the belief of bespoke battery ideas in file time.


WAE’s modular toolkit allows automotive prospects to create customized pack and sub-pack methods quicker, supporting low- to medium-volume electrical car builders throughout a spread of industries. Every module is 1.08 kWh with a voltage of 50V Max, 43V Nominal with an power density of >240Wh/kg.
