Is horsepower or torque more important for uphill driving?

[Victoria]

The climbing ability of a car mainly depends on torque (twisting force) and the RPM at which peak torque is generated. Here are the relevant details: 1. Peak Torque: The lower the RPM at which peak torque is reached (the earlier the torque output peak curve appears) and the higher the torque value, the better the theoretical climbing performance and the greater the initial acceleration G-value. 2. Climbing Ability: Climbing ability primarily depends on torque. Wheel torque is determined by engine torque, transmission gear ratio, drivetrain gear ratio (final drive ratio), and wheel radius. A car with high torque isn't necessarily fast; high torque only indicates that the car has strong traction. The lower the car's speed, the stronger the torque.
