Yes and no. Torque is thrust. Hp is torque x rpm basically. So depending on your torque curve, if you make your torque early in the rpm range, you will have higher torque numbers and a good launch. If you make the torque later in the curve, you will make higher hp numbers and have power later after you're moving. Ideally you want a flat torque curve so you have the thrust evenly over a broad range of rpms. My 335i e93 is like that. Flat torque curve, 675 rwhp, 650 rwtq. Also, remember torque is different at the engine than at the wheels. The drivetrain typically leaches 10-20% of the power. Rotating mass, transmission type, etc. Reduce a car makers engine numbers by 15% or so to see about what rwhp/rwtq are for comparisons.
