The Real-World Horsepower of Electric Cars

Tesla model s on dyno at 428.2 Horsepower!

What do batteries and electric motors add up to in real-world HORSEPOWER? It's all about the conversion of HP to torque -- 600 HP from a gas car usually equals about 400 pounds of torque. In a gas engine the torque and HP meet at 5500 RPMs. The electric motor can make the same torque at 1000 RPMs or less. Watch the video:

"What does 85kw hours equal in raw horsepower? The Tesla Model S on a dyno machine in this video will answer that question, 428.2HP! Imagine the torque! It's probably much higher," said Tom Lloyd, owner of Elite-Exclusive Custom EVS.



Here's his report on the power of electric cars:


A 600 HP combustion (gas-powered) engine usually generates 400 pounds of torque that is easily surpassed by a 300 HP electric motor. 

Speed TV had a car building show called Stacey David. He built an SLC kit-car on the show that demonstrated the power and speed that can be achieved in building and converting muscle cars. The car looked nice and went together well. We have built the Factory Five GTM and made it electric. However, It took over a year to get the parts from F5. 

We have also been working with the Tesla Roadster, which is a Lotus Elise with electric drive. The Lotus has an all aluminum chassis and fiberglass body. We have been able to buy several Tesla roadsters for considerably under retail value. We have a Model S Tesla in the shop that we are doing aluminum repairs to. We have two other aluminum chassis at the shop that we built -- All of these cars  are capable of achieving 428.2 HP because of the 5x greater torque ratio.

Audi A8 electric sporty sedan 
This Audi A8 sporty sedan with an all-aluminum body was modified to accommodate an electric motor, batteries and a range-extending on-board recharging system.




GTE electric sports racer


The best power and performance is achieved by using two smaller electric motors at 300 HP each because smaller electric motors spin faster. The higher the volts and amps the more power you make. This is what we did seven years ago, when we built the original Sigma GTE racer. An added advantage is to drive the front with one motor and the rear with the other. The most successful race cars are 4-wheel drive.

Here's his report on the range of electric cars:


On average you get 10 miles range for $1000. 200 miles is $20,000 in batteries. We currently have a Sigma GTE sports car for sale, ready to race or ready to be detailed with custom body and paint.

We are constantly designing new body styles and have other designs to work with. There are many options. We can offer the GTE in the mid-40's range and the Audi A8 with all-wheel drive at $70k. 


The Audi A8 travels up to 150 miles as an all-electric and is capable of cross-country driving, utilizing an  on-board recharge/range extending generator based on a V-Twin bike engine connected to the factory gas tank (that gets over 100 miles per gallon while recharging the electric batteries.)


These are the exclusive custom electrics we have to offer at the moment -- and we would be more than capable of building the exotic custom electric of your dreams -- based on a kit-car, one of our original designs or conversion of a gas-powered vehicle." - Tom Lloyd @TCLloyd@gmail.com.
