Sonett Electric Owners Manual

Reinventing the 1969 Saab Sonett as a 21st century electric car has a back-to-the-future feel to it. We created a special Owners Manual to accompany our new EV, a blend of the original manual and changes that reflect its state-of-the-art lithium battery pack, alternating current motor, and regenerative braking capability.



This 64-page 9×7-inch paperback is available from Lulu Press.

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.
