Smooth is Fast.
Slow Hands on Corner Entry.
Slow In, Fast Out.
The Holy Trinity of proper racing technique is completely wrong — at least if you want to be a champion driver. Onboard videos from F1, WRC and the various touring car series show there is so much more to it. The racecar is thrown into corners with supreme confidence and caught with the deft but quick hand movements that seemingly defy all laws of physics, running completely counter to the smooth is fast dogma.
So why do modern ultra-competitive racing techniques look nothing like what you were taught in driving school or read in a book?
The answer lies mostly in reducing the transition times between maximum acceleration and maximum cornering.
If a driver knows a car can go through a corner at a certain speed and steering angle, there is no reason to waste time getting to that precise velocity. Lost time is simply that — you lost.
The next time you're strapped to your couch watching a Formula 1 race, take note of the driver's hands on corner entries. The movement should be confident and fast and then slow down just as the maximum cornering forces build. The steering wheel is used to balance on the hairy edge of adhesion with little flicks that vary only with grip levels. It seems easy, until you realize the velocities at which these folks are trucking along. Lewis Hamilton's pole-setting lap at this year's Monaco GP is just one such example.
This fast and nasty driving is sometimes called "Pitch and Catch" as the car is chucked violently into a corner and then carefully gathered up as it nears the apex. There are subtle differences in technique when applied to different types of driving. The high grip of race tires on a dry track will have lower amplitudes of hand motion mid-corner, while the low grip of a rally car will have more relative hand motion during this dance of speed. It's quick and looks incredibly violent from a cockpit camera point-of-view.
Ari Vatanen's epic run at the 1983 Manx Trophy Rally (Isle of Man) is a textbook lesson on this:
Transition times during braking must also be reduced. There should be little or no time lost between wide-open throttle on a straight and a braking point before the next turn. Coasting between gas and brake isn't going to win you anything, nor is being light-footed with the middle pedal. You must use your brakes hard — but not for too long.
One common characteristic of champion drivers is not slowing the car too much on corner entry. A faster driver will trail off the brakes earlier in the turn at a higher velocity. This can be seen on data acquisition traces of velocity vs time as a slower driver's speed will trend downwards earlier and lower than the leaders. Slow in, fast out is replaced with fast in, fast out as the racer progresses through the field.
By entering the corner at a higher rate of speed, the overtaking car will appear to be doing the passing under braking. This can create an illusion of a faster driver adhering to the slow in, fast out mantra. In reality, it's more correct to think of this racer ending the braking sooner than a slower competitor. The faster car is faster at that point on the track and has the skills to back it up mid-corner.
This holds true for autocross as well. Witness champion autocrosser, Mark Daddio:
Before you run off and plant your car firmly into a ditch (or into a tire wall — too soon?), we must remind you there's a reason schools preach slow hands and smooth movements are better. And they are, especially for novices who still need to learn basic car control skills or even the way around a racetrack.
It's very easy to overload the tires with quick jabs and stabs. If an instructor tells a novice driver to move their hands quickly on corner entry, they'll typically overshoot their hand movements. This will upset the car and the novice doesn't have the talent and experience to adjust and countersteer midway through the curve, especially if anything unexpected happens. This goes double on the street.
How do you get from slow hands to fast driving? Like the old joke about how to get to Carnegie Hall — "Practice!" With experience, you build speed incrementally, one almost-botched corner at a time. The act of saving your ass lap after lap slowly trains your eyes, feet and hands to work together at the limit.
Don't worry about being smooth — smooth is for suckers.
