Torque (lb-Ft) HP (kW) Battery (kWh)
Spark: 327, 97, 19
Leaf: 190, 80, 30
Why the need for that much torque on the Spark, i.e. a vehicle lighter than the Leaf?
Could this be a motor that the Bolt will have, and the Spark provides a test vehicle
for an early production of that motor?
I could never figure out why the Spark
EV had such high torque. It didn't seem to do much, despite muscle car torque numbers it could only muster mid 7's in 0 - 60 runs. Quick for an EV but nothing compared to even an ordinary ICE powered family sedan. Torque is important for low end grunt but HP may be the better measure for overall performance, and the Spark
's HP isn't much more than the Leaf.
Most people think the Spark
EV drivetrain will be used in the Bolt. Personally I don't think so. The Bolt will be bigger and weigh a lot more, so the puny horsepower output of Spark
EV drivetrain in my opinion is too low. Rather than develop a more powerful single motor drivetrain, I think it makes more sense to use the Voltec propulsion system because it already produces adequate torque and horsepower and the two motor design is more efficient at highway speeds than the Spark
