Fancy yourself a magician? Here's a trick that'll impress your friends: It's called a "heel-toe" downshift. When slowing for a corner while already pressing the brake pedal, simultaneously blip the throttle so the engine spins at the correct speed for the gear you're shifting to. Like any good card trick, it sounds simple but can be extremely hard to learn. Perhaps Nissan's SyncroRev Match is a better solution. Using computer magic, SynchroRev automatically keeps the engine revving at the right speed for any gear, allowing you to look like an expert driver when you make gear changes, minus the effort. We couldn't ask for a better illusion.
