A rev-matching technique where the driver blips the throttle with the right foot while simultaneously maintaining brake pressure, then shifts to a lower gear. This prevents drivetrain shock and keeps the car stable during corner-entry downshifts.
Bentley provides the step-by-step in Ultimate Speed Secrets: "1. Begin braking, using the ball of your right foot on the brake pedal while keeping a small portion of the right side of your foot covering the gas pedal but not pushing it yet. 2. Depress the clutch pedal with your left foot, while maintaining braking. 3. Move the shift lever into the next-lower gear, while maintaining braking. 4. While still braking and with the clutch depressed, roll or pivot the right side of your foot onto the gas pedal to blip the engine." He emphasizes the key principle: "The smoothest downshift occurs when the engine revs are increased by briefly applying, or stabbing, the gas pedal with your right foot. This is called blipping the throttle. This matches the engine rpm with the driving wheels' rpm." The technique is distinct from the existing "Heel-Toe" entry because this focuses specifically on the downshift application during braking zones, whereas heel-toe is the broader pedal technique.
