Free to use. Modular EV platform.
What is it?
TABBY EVO is a hardware open source platform for electric vehicles. Free to use, available to everyone.
It’s the 2nd version of our platform: now it’s harder, better, faster and stronger.
It is an open source framework for the creation of vehicles: it can be used to bootstrap businesses (electric vehicle startups), to create your own vehicle, for education purposes, and much more.
By using it you can save a lot of millions of dollars and years of R&D.
All the plans and blueprints can be downloaded in the website’s download section. You are welcome and encouraged to improve the designs, work on them, and upload them to share your ideas with the community through the OSV forum.
Inspiration: Tabby cats are cute, sharp and very intelligent. Although other cats are also intelligent, these cats learn well to live with humans and enjoy their lives.

Idea
Why?
We heard your feedbacks! Because some of our major customers and partners asked us for high road keeping capabilities at higher speed (up to 130 km/h – 80 miles/h ) and higher frame stiffness and robustness (for emerging countries) which were difficult to satisfy with the first TABBY design so we decided to push forward the TABBY EVO platform which can meet those requirements.
Now it’s harder, better, faster and stronger.
Who developed it?
Roberto Chiavini: born in Assisi, studied in Perugia and learnt how to develop vehicles in the special area of Modena, cradle of some of the most famous brands in automotive and motorcycle industry like Ferrari, Maserati, Lamborghini, Pagani, De Tomaso and Ducati.
He got experience in Tazzari with the Zero, one of the best electric vehicles created in Europe on an L7e platform (heavy quadricycle) and M1 (highway legal) and Townlife L6/L7, he has also a racing background with Formula Modena, a 190km/h race legal vehicle, in design, development, structural analysis and homologation.
He joined the OSV team in 2015 and developed the evolution of OSVehicle platform.
