WAE, the former expertise offshoot of the Williams System 1 workforce, will use this week’s Low Carbon Car Present within the U.Okay. to current the EVRh, a modular platform packing a hydrogen-electric powertrain.

The platform is a observe as much as WAE’s EVX and EVR platforms designed for battery-electric autos, and builds on each of these platforms by including a hydrogen gasoline cell into the combination.

A hydrogen-electric car is actually an EV that makes use of a hydrogen gasoline cell to energy the electrical drive system as an alternative of a battery. The gasoline cell combines hydrogen with oxygen from the air in a virtually emission-free course of that creates electrical energy.

In WAE’s EVRh, there’s additionally a battery that may ship energy to the drive system. The battery will be charged by the gasoline cell or by EV charging infrastructure—one thing that may be helpful for the proprietor of any car based mostly on the EVRh platform given the dearth of hydrogen fueling infrastructure.

The battery is able to discharging as much as 576 hp whereas the gasoline cell can discharge as much as 160 hp, leading to a mixed discharge of as much as 736 hp. This can be utilized to energy electrical motors both in rear- or all-wheel-drive configurations.

Peak efficiency estimates for a car based mostly on the platform embody 0-60 mph acceleration in beneath 2.5 seconds and a Nürburgring lap time in beneath 7:20. The present lap file for an EV on the ‘Ring is the 7:05 set by a Rimac Nevera in August.

The vary estimate is greater than 350 miles.

The EVRh contains a light-weight composite construction that serves because the passenger cell, with the battery mounted behind the cabin as an alternative of within the flooring, like in most EVs on sale right now. The design avoids the difficulty of getting a raised flooring, whereas additionally replicating the acquainted weight distribution of a mid-engine automobile. Hydrogen storage tanks are mounted on the entrance and rear of the platform.

The Low Carbon Car Present begins Sept. 7 and takes place on the U.Okay.’s Millbrook Proving Floor.
