After having driven a hybrid car for the first time I was curious if it would be possible to retrofit this kind of technology to an existing vehicle. Basically an electric drive which connects into the crank, or there abouts, which can assist when the engine is under load. Surprisingly there isn’t that many products on the market, with the exception of this: Electrocharger / Retrofit Hybrid :: Sigma Automotive
I’m now searching for some products which are actually in production, or some DIY projects. Any help?
