Kriss Motors Electric Conversions


Time on the track is the only way to push the performance envelope and verify what the true capabilities of the electric Speedster are.

Happily, based on autocross runs, handling is superior to gas powered Speedsters due to a better 49.5/50.5 front/rear weight balance as well as a lower center of gravity.

The Speedster curb weight is 2,009 lbs (calibrated scale).

The Cars

Porsche 356 Speedster

The iconic Porsche Speedster proved to be an excellent EV conversion candidate due to its low weight, relatively simple design, and ample front/rear compartments for mounting pristmatic lithium battery cells. Weight distribution was improved over the original rear engine configuration with better acceleration and overall performance.

Saab Sonett

The unusual fiberglass Sonett, originally powered by a Ford V4 engine, combines a low center of gravity and front wheel drive, optimal for our high performance EV conversion. Without the need to accomodate a long drive train, the space behind the two seats was used for additional batteries. The original four-speed transmission remains intact along with the braking system.
