Alternate fuel projects have been peeking over the horizon for the past few years.
Entropy Racing had been considering options from diesel, to hybrids, but ultimately settled on electric for a number of reasons, not the least of which is that it is cutting edge. Electric power addresses many of the current concerns the public has with both motorsports and with cars in general. Best of all, it is fun and exciting stuff to play with.
At the end of the 2013 race season, Entropy Racing started to give some serious thought to a new project that would really showcase the shop’s talents and versatility. The discussion of current trends and exciting projects out in the world had been getting our interest. One of the common recurring themes was that the only truly successful electric race car projects noted were backed by millions of dollars, the world’s best engineers and years of development. Entropy decided to take a stab at producing a low cost, viable electric race car for a variety of events in a small fraction of the time and budget.
The result is a complete race car, dyno tested and ready to race in less than 3 months.
The First Generation EVSRs were based on a popular Sports Racing car which was heavily modified to accommodate the power plant and battery packs in a safe, lightweight nimble package. The frame was constructed of square tubular steel which is both stout and relatively light. Power was provided by an AC electric motor rated at 180 horsepower, with 180 pound-feet of torque instantly available through its entire speed range. The power was transmitted through a conventional automotive differential and custom drive shafts. There are disc brakes on all 4 corners and the steering goes through a very tight rack and pinion.
The Second Generation EVSR was introduced in January 2020. While retaining much of the proven driveline and suspension, EVSR performed a complete redesign of the safety cage and battery containment, and streamlined wiring, accessories, and added a fully-integrated electronic dashboard. The most noticeable difference is a brand new, single piece body designed and executed in-house; which reduces weight, offers better aerodynamics, and increases serviceability.
EVSR had undergone a strenuous testing regimen at the dyno and at the shop in its early development. Over the past 8 years, EVSR has been proving its capabilities well attending over 100 events; ranging from road courses, hill climbs, autocross, endurance racing, and even a trip to the drag strip. Our custom programming has been developed with the focus upon balancing efficiency, range, and performance – making EVSR the most successful road-racing elecric cars in the world.
The Entropy Racing EVSR program has and continues to show the racing world that electric race cars are not only possible, but viable and attainable to the racing community, without nearly as many zeroes at the end of the invoice.
EVSR is less revolutionary, than it is evolutionary.
EVSR has grown from solid racing principals and a well proven design principles. We look forward to paving the way for many EVs on the track competing, quickly, cleanly and quietly.
