Autocross is a driving skill event over a short,
miniature road course clearly defined using traffic cones. Each vehicle
is timed individually as it negotiates a course that puts the emphasis on
driver skill and vehicle handling using time as a means to measure proficiency.
The skills learned and practiced here; smooth transitions, enhanced
braking and skid correction have an immediate impact on your
driving skills and will translate into safer street driving.
Current Class Champions
The rules and guidelines cover participant, site, safety and vehicle
capabilities. They are a result of this club’s 50+ years of experience
and the experiences of many similar clubs from all around the country.
There are course standards that must be met to protect the participant,
the facility and the neighborhood. All cars must pass a safety inspection.
SCCNH sanctioned events are conducted under the watchful eyes of Safety
Stewards insuring autocross to be one of the safest motorsports.
The events are low-keyed, with the emphasis on fun. Instructors are
available to assist and ride along with novice drivers or any driver who
feels they could use some improvement. At the beginning of each season
an autocross school is held where you can learn how to autocross or improve
your skills with instruction from the experts. This is an opportunity to
test the handling ability of your car and your capability as a driver in a

Results & Awards
Event results will be here within one week (usually within a day or so)
following the event. Click the Results button at the top of this page.
The top three positions in each class will be awarded dash plaques denoting their position.
We keep track of the points that you accumulate throughout the year based on how you place at
each event. This is kept track by your number. Therefore it is important that you use the same
number and SCCNH class. If you are going to run in a different SCCNH class you need a different number.
However, if you change SCCA classes but remain in the same SCCNH class you can use the same number.
Starting at first place in class you get: 10,8,6,5,4,3,2 and everyone else gets 1. We count your best
seven of the eight events. At the end of the year, SCCNH members receive awards based on placing in the
top three positions of each class.

We run seven (7) classes that are all indexed using the PAX/RTP modifiers. This Index was developed
by Rick Ruth and reflects study of results from well over 500 nationwide Solo events including, the
Solo National Championships, National Tour, Alabama Region, Atlanta Region, Chicago Region,
California Sports Car Club, Central Florida Region, Equipe Rapide (Florida & Texas), Great Lakes Solo Series,
Hawaii Region, Houston Region, Midwest Divisional Series, Milwaukee Region, Minnesota Autosports Club,
New England Region, Northwest Region, Northern New Jersey Region, Oregon Region, Philadelphia Region,
Rocky Mountain Series, San Francisco Region, San Diego Region, South Jersey Region, St. Louis Region,
Tri-State Sports Car Council, Texas Region, Washington DC Region, Wisconsin Autocrossers Inc., and many,
many others. This system is meant to allow different classes of cars to run together and be competitive.
Your time is modified by multiplying it by the PAX/RTP index for your SCCA class. In theory this would
allow a Honda Fit to fairly compete with a Porsche GT3.
Five of our classes are based on the types of vehicles that generally come to our events and are designed to
group cars with similar modifications together. The objective is to get eight to twelve vehicles in each class.
The two stock classes are for street tires only (no R-comp tires). Street tires are defined as DOT approved
tires with a UTQG wear rating of 140 or more. (UTQG: Uniform Tire Quality Grade - The U.S. Department of Transportation (DOT)
National Highway Traffic Safety Administration's (NHTSA) Uniform Tire Quality Grade Standards (UTQG) were
originated to provide consumers with useful information to help them purchase tires based on their relative
treadwear, traction and temperature capabilities. This is declared on the sidewall of all DOT approved tires.)
Generally a lower number signifies a softer, sticker tire. We get a lot of stock street tired vehicles, so we
created two classes. The Stock Performance class is for most sports cars and high performance sedans and coupes.
The Stock Sedan class is mostly family sedans and coupes. We chose to split these by the SCCA stock classes, see the list below.
We get a lot of vehicles that have been modified but are still street able. Most fall into what SCCA calls
Street Touring and Street Modified and therefore we created those classes.
All remaining vehicles go into our Race class. This includes stock cars on race compound (R-comp) tires (UTQG wear rating below 140).
The Novice class is open to drivers that have not been in a raced including autocross, solo, HPDE and hillclimb in
the past 20 years and are driving a street car (regisered) with street tires (wear rating of 140+).
The Ladies class requires six or more ladies that want to run by themselves. They must declare that they want a
Ladies class on the day of the event.
