Retrofuture FRANCE has chosen 15 iconic models and sold 70 in presale in 6 months. In the US, EV West sells kits for 14 cars. In California, Electric GT offers “swap” packages for V8, Straight 6, and 4-cylinder engines, even aestheticized to echo their predecessors. As for things like “impossible” 7-series and their ilk, one only need consult a matrix to balance one’s priorities among speed, range, weight, and price.
