If that's not impressive enough, the builder has made the promise to drop below the 10-second mark by spring.
Launched more than two years ago, Factory Five’s kit car was engineered to accommodate the hardware of the Subaru Impreza and WRX. The name “818” comes from the targeted curb weight of 818 kilograms, but that’s no longer the case since the car here has been vastly modified and it no longer has a combustion engine. During the first phase of conversion, the folks from Tapp Auto installed the drivetrain of the Tesla Model S 85, which bumped weight to 1,133 kg. With more than 400 electric horsepower on tap, the car was able to run the quarter mile in 11.5 seconds.
Not entirely satisfied with the performance of the car, the builder then decided to remove the 85 hardware in order to install the drivetrain of the beefier P85 version, while keeping the first build's dual battery packs sourced from the first-generation Chevy Volt. Fitted with the new gear, the electric kit car was able to cover the quarter mile in 10.1 seconds, making it even quicker than the Tesla Model S P100DL recently clocked on the drag strip at 10.7 seconds (see video below.)
Getting back to the heavily customized kit car, the author of the conversion believes there is still room for improvements to further boost performance on the drag strip. He goes on to specify that with additional changes, the do-it-yourself EV will be able to cover the quarter mile in less than ten seconds by the spring of next year. It's worth pointing out that aside from installing the bits and pieces from a Model S, the folks behind the project also had to create the necessary software.
Until then, the current specification of the zero-emissions kit car will embark upon a range test next week to find out how much juice those two Volt-sourced batteries running in parallel can provide in real world driving conditions. According to the builder’s estimation, the kit car should be able to cover more than 200 kilometers on a single charge.
