Yes, you are 
You feel torque. Horsepower is just a function of torque/rpm. |

- What you feel comes from force at the wheels, which comes from wheel torque.
- Wheel torque != engine torque, though they are proportional for any given gear ratio.
- For any given velocity, wheel torque increases if power increases (regardless of engine torque).
- The typical dyno plot does not show wheel torque (discussed last November in the FR-S/BRZ vs. Genesis Coupe thread).
