Final Drive
Electric specifications: AC35X2 Example
Also available using Siemens, Netgain and the Tesla motor for higher performance and range.
Missing is the usual Subaru Boxer engine, replaced by a AC35x2 motor fed by a 16-kWh lithium iron phosphate battery constructed of two 8-kWh sub-packs. The motor and battery unit is still connected to a WRX Six-speed manual transmission that allows for reduced energy consumption and management of the motor’s output.
Speaking of output, the motor zaps out 165 horsepower and 189 pound-feet of torque to the rear wheels. It might not seem like much, but the entire car will weigh just under 2,000 pounds. The top speed is easily 150 mph. This is estimated.
The 0 -60mph are looking around 4seconds, other motors can easily provide sub 3 seconds.
The car will take you 100 miles from a full charge and take 4 hours to fully charge the batteries.
Using the Tesla motor with the Chevy Volt battery pack supports a higher discharge than Tesla’s battery, but Tesla’s drive unit is more powerful than the Volt’s, which makes combining the two an interesting idea for an all-electric drag racing car.
Using the Tesla RWD drive unit and Volt packs in the car. The result is an all-electric sports car with over 400 hp and weighing 2500 lbs. The vehicle completed the 1/4 mile in 11.5 seconds at a speed of 115 mph, which is fairly impressive for a new powertrain and it can only get better..
