MD-Tech has been continuously working to improve their product since launching their product in collaboration with Enginer. Current kits are made to be nearly plug and play. The MD-Tech kits are designed to require minimal modification of the stock Prius. The kits supply power to the stock hybrid battery with a controlled voltage acting as a battery re-charger. Because of this, all-electric driving is obtainable for short distances even though the kit design is primarily for mileage enhancement.
