The Patented Goodwin Assist is a revolutionary new technology for converting Hummers into highly fuel efficient plug in hybrids. The Goodwin Assist is focused squarely on bang for the buck proposition of maximizing fuel savings with minimal capital investment resulting in the shortest ROI. Benefits: 18-24 Months ROI 60% Fuel Cost Reduction 60% Less Emissions The Goodwin Assist provides 80% of the financial benefits of other solutions at 20% of the cost. Typical drive trains, transmissions and internal combustion engines are highly inefficient. Goodwin Assist components include a state of the art electric motor, system controller, and a modular lithium ion battery pack...which can be plugged into any standard 110 outlet, to store inexpensive power from the grid. The Goodwin Assist applies that stored energy via the electric motor to assist the internal combustion engine when it is most inefficient, significantly reducing workload of the engine and the use of fossil fuel. This duel-fuel approach allows vehicles to take advantage of the great power delivered at the equivalent of $0.75 per gallon. The Goodwin Assist reads the engines performance and increases the assist when the internal combustion engine will benefit most from a fuel saving perspective such as frequent starts and stops. The Goodwin Assist requires no EPA approval or crash testing, and is comprised mostly of approved off the shelf components from industry leading automotive providers. Once converted, these vehicles see their fuel cost is cut in half or more. The conversion process is simple, inexpensive and requires no major overhaul of the vehicle. Goodwin Assist's unique engineering allows for uninterrupted driving on the unlikely event of a system or component failure, making The Patented Goodwin Assist the only alternative for critical vehicle operation. This development has seen multiple generations of prototype vehicles with significant efforts placed on safety, components testing and systems engineering . Untold hours of refinement and testing as well as enough miles driven across the United States many times over has allowed us to prove The Goodwin Assist system. The vehicles have exceed over 100 MPG with a simple to install retrofit solution.In addition of course is a performance mode. This mode allows the end user to maximize the performance benefit of the electric motors power. It becomes a reverse supercharger. Another feature of the system is regenerative braking. In this mode the Goodwin Assist becomes a generator for those critical times were electricity is at a premium.
