1. RPM and Gears
RPM = how fast the engine spins. The 400z can spin up to 10,700 RPM (revolutions per minutes). Gears help convert that engine speed into road speed.
Each gear covers a range of speeds, example:
- Gear 1: 0–35 km/h
- Gear 2: 10–55 km/h
You can hit high RPMs in any gear, but the actual speed changes.
2. Torque vs Power
- Torque = the pull you feel when you open the throttle. It gives acceleration.
- Power = how well the engine keeps pushing as speed builds up.
Both torque and power peak in specific RPM ranges. For 400z, torque is best between 6k–9k RPM.
3. What Happens When You Shift Gears
- Upshifting = moving to a higher gear → RPM drops, speed stays same.
- Downshifting = is the opposite, moving to a lower gear → RPM increases
Example: At 35 km/h in Gear 1 = 8k RPM.
Shift to Gear 2 = drops to ~5k RPM.
4. When to Shift for Best Performance
To stay in the strong pull (torque) zone:
- Upshift near 9k RPM, so it drops to ~6k after the shift.
- Downshift if RPM falls below 6k, to bring it back into the sweet spot.
Used Torque, RPM, etc. numbers aren’t the actual value, only example.
Used gpt for proper format.
