Electric Porsche 911 - 10 years of development.

We have a very special car in the workshop at the moment. Our first ever car we converted to electric specifically for a customer. It's a 1979 Porsche 911 SC. So we thoughts it's a perfect opportunity to see how things have developed in 10 years and compare it to the very latest Porsche 911 that we've converted to electric. How have batteries evolved in that time and what other features have we been able to improve and add to our conversions over those 10 years.
