Line 1: Line 1:
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.
 
  
'''Performance'''
 
* Performance numbers are for research and testing purposes only and may vary.
 
Top Speed
 
Depends on the bodywork
 
100 Km/h (62 mph), platform only
 
129 Km/h (80 mph), but depends on the bodywork and low Cx coefficient
 
Max Range on standard batteries
 
Depends on the bodywork
 
80 Km (50 mi), platform only
 
120 Km (75 mi), but depends on the bodywork and low Cx coefficient
 
Max Climb*
 
Stable at 25%
 
* Depends on final vehicle weight
 
Approach and departure angles*
 
Approach angle: 35 degrees
 
Departure angle: N/A (wheels are behind the chassis)
 
* Note: Platform only, numbers will change with weight and exterior body designs
