School
of the Controlled Skid

Rally racing is a messy hoot.
But first you have to unlearn most of what
you know about driving.

THIRTY-ODD YEARS of driving, including a road racing license,
and I just can't get my left-foot braking. Not Tim O'Neil's
version anyway, a precise ballet requiring that two feet control
three pedals, the goal being to shortcut sharp, snow-covered
corners side ways at 30 mph. And frankly, O'Neil, a five-time
U.S. and North American Rally champion, isn't helping matters.
"Turn! Brake! Release! Countersteer! Accelerate!"
He shouts as we skid around a hairpin turn, adding in a crisp
New England drawl, "Oh, Jonny, this isn't good."
It's day one at the team O'Neil Rally School in Franconia, New
Hampshire. It's billed as "the world of high speed driving
on loose surfaces," though a more accurate description
might be the art and science of controlled skid. Over three
days, I learn how to push '80s-vintage sedans way past their
limits and use the resulting chaos to my advantage.
O'Neil is one of the premier rally schools in the world, though
the sport- the soccer of motorsports- has been relatively unknown
and certainly underappreciated on the side if the Atlantic.
In Europe, it draws spectators en masse to public roads from

Breakneck speeds on the public
right-of-way, however, never passed muster here.
But now, thanks to increase TV
coverage-made more interesting with in car cameras-and
a handful of popular videogames, that's changing. So much
so, in fact, that several automakers are introducing production
versions of the rough-and-tumble racers. Due out this
spring is the Mitsubishi Lancer Evolution VIII, an all-wheel
drive (AWD), packs 227 horses into a 2.0-liter turbo engine
and is selling like high-test coffee at a 4 a.m. rally
checkpoint. Subaru also plans a more powerful STi version,
due put this summer.
Racers used to modify production
cars with tougher tires, special lights and a power tweak.
But today's top pro rally cars retain little more than
the original body shell. Most boast a 400-hp-plus turbo
engine, stiffened chassis; roll cage, rugged transmission
to handle all the power, and an assortment of tires to
tackle just about any terrain from asphalt to ice.
But at O'Neil's school, the tech
is more down and dirty. Here, front-wheel-drive training
is taught in mid-'80s Volkswagen Golfs outfitted with
roll cages, safety seats and rally tires. A similarly
equipped Audi 4000S Quattro is used to teach AWD skills.
They're rugged and affordable, and with 85 and 115 horses
respectively, they won't run away from novices like me.
The key to handling them is weight
transfer. Hard braking shifts weight forward, adding to
front wheel traction while sending the rear skidding wide
through turns-quintessential oversteer. Shift weight to
the rear and the front wheels lose grip more easily-in
other words, understeer. Either way, speed is your friend.
Enter a turn too slow and you'll stop instead of skid.

Here's how to put
theory into practice: Entering a right hand curve, for
example, rotate the wheel 90 degrees right to start the
car turning. When the front moves right, jab the brakes
hard with your left foot, keeping the accelerator partway
down with the right. This shifts weight to the front for
extra grip; the loss of traction in the back increases
the car's rotation around its vertical axis. Ease off
the brake and crank the steering wheel left 180 degrees
(90 degrees left of center) and press the accelerator.
This shifts weight to the rear, stopping the car's rotation.
Do it properly and you'll accelerate out of a corner.
Flub it, as I did repeatedly, and you'll slide headfirst
into trees, tumble sideways and roll, or spin and slide
backward into the woods. O'Neil tries to reassure me:
"I've crashed hundreds of times." No wonder
he conducts this training on a flat, open skidpad.
The maneuver is difficult enough
when the surface is consistent gravel, but the night before,
3 inches of snow fell on the White Mountains, creating
a surface that now varies from packed snow to a gorp of
mud, gravel and slush. And there's more to learn that
righthand skids-one needs to turn left as well. For whatever
reason, I'm better at right turns. Rear-or all-wheel drive
changes everything. And the sharpest corners call for
a "pendulum turn," the hardest part of my instruction
here. It consists of feinting a move one way and then
turning sharply the other so the rear end swings even
faster-a sort of automotive crack-the-whip.

Day three is my
final test. That's when we head out to mock rally course
in the woods to lean combination corners and uphill and
downhill turns. Shady areas are so icy that even O'Neil
slides off the road during demonstration runs. And while
there's better grip on the beaten paths, they still covered
by slop that splatters spectacularly through turns.
That afternoon, however, my training
starts to jell-timing and balance yielding momentary flashes
of brilliance amid hours of struggle. It's tough to teach
an old dog new turns, but I'm undeniably quicker through
the slalom and under better control.
Not that we've been doing anything
at high speed. Training has been limited to second gear
to minimize another difficult technique: shifting. Unlike
in road racing, where downshifting is done before a corner,
rally downshifts happen while the car is skidding through
the corner. That's the lesson for the four-day course
that also includes handbrake and 180-degree turns, says
O'Neil. Psyched about my late-developing just in time-before
I unlearn how to get home.-JOHN MATRAS
