A driving technique using the right foot to brake with the toe and blip the throttle with the heel during downshifts. Essential for fast manual driving.
Heel-toe (also called heel-and-toe) is a manual transmission driving technique where the right foot operates both the brake and throttle simultaneously during downshifts. The toe of the foot presses the brake pedal while the heel rotates to blip the throttle. The throttle blip raises engine RPM to match the new (lower) gear, allowing smooth clutch engagement without lurching.
The technique is essential for fast driving. Without heel-toe (or rev matching), downshifting while braking causes engine RPM to drop below the speed required for the new gear, causing the rear wheels to slow suddenly when the clutch engages. This can upset the car balance, lock the rear wheels (especially on RWD cars), or cause unwanted weight transfer. Heel-toe allows seamless braking-and-downshifting without these issues.
Modern cars often have automatic rev matching as a feature (Nissan SyncroRev Match, Porsche, BMW). The car ECU automatically blips the throttle during downshifts. Some drivers prefer manual heel-toe over automatic rev matching for the engagement and skill aspect; others prefer the automatic option for consistency. Both approaches achieve the same result of matching engine RPM to the new gear.
