NEDRA Classes,
Voltage Divisions and Record Rules
To
race in National Electric Drag Racing Association sanctioned
competition events or to earn a
NEDRA World Record vehicles are categorized by
Class and Voltage. Classes are determined by the extent of the
vehicle's modification from daily drivers such as simple Street
Conversions (SC) to extreme racers like in the Extreme Street (XS)
class. Classes are available for both cars and motorcycles. Voltage
Divisions begin with 24 volts for division J and step upward to
division A5 for over 600.0 volts. Refer to the table, Voltage
Divisions, shown below. Please note that the old procedure for
deriving voltage division by counting lead acid batteries to
determine 'Nominal Voltage' is no longer valid. The only valid
method for division determination is by direct voltage measurement.
The voltage measurements may be made immediately prior to leaving
the pits, in the staging lanes, or at the starting line.
Example:
A car determined to conform to the Pro Street
Conversion class [PS] with a battery pack measured to be 237.6 volts
would be designated as PS/B.

mile distances.
A vehicle may only set one record at each Event.
A valid time slip must not include a driver error (red light).
A record time must include a backup time from the same Event.
If two times are within 1% of each other, the quicker time shall be
the record time and the other time shall be the backup time.
If two times differ by more than 1%, the quicker time shall be the
backup time and the other time shall be the record time.
4) Record Submission Procedure:
NEDRA Race Form must be properly filled out by the vehicle owner and
signed by the track inspector.
Two valid time slips are required.

Broken Arrow, OK 74012
or email to:
recordkeeper@nedra.com
*An Event is considered an NHRA, IHRA "Test and Tune,"
official competition or NEDRA sanctioned competition that spans a
period of a day or weekend. If two separate events are held on the
same day, at the same track, a racer can achieve two records for
that day if they are made in each "official" event. A tech form will
be required for each record made.
Class Descriptions
NEDRA Classes
|
Each
educational institution will be able to compete in ANY class and
division they would like to. (Previously there were only two, HS and HS
Modified. And weirdly cars and motorcycles and dragsters were all in the
same class.) Now there will be two different "certifications" the
institute can get. HS for High Schools and High School level trade
schools and ED for Educations of higher learning such as colleges and
universities and post-highschool college level trade schools. They can
compete in any class or division and if they qualify as such an entity
and have the fastest time for HS or ED, they can earn that certification
on that record. They may be faster or slower than the non-certificate
record.
4-Wheel Car/Truck/Van Class Overview
Vehicle Classes for Cars/Trucks/Vans are broken down into
three types. Conversions, Production and Drag Vehicles. Each
Class has increasing amounts of alterations that can be made
for racing purposes.
Those alterations are summarized in the "Watt's
Allowed" Tables below.
PRODUCTION CLASSES
Street Production (SP)
The Street
Production (SP) class is for basic street legal and licensed
mass produced vehicles that are originally created to be
EVs. An example of a production vehicle would be Tesla's
Roadster, not significantly modified for racing.
Pro-Street Production
(PP)
The Pro
Street Production (PP) class is for street legal and
licensed vehicles that have minor performance or alterations
from the original production specs while still maintaining
their street appearance and drivability.
Modified Street Production
(MP)
The Pro Modified
Street Production (MP) class is street bodied and stock
chassied vehicles that have been heavily altered from the
original production specs for racing.
CONVERSION CLASSES
Street Conversion (SC)
The Street
Conversion (SC) class is for basic street legal and licensed
conversions that have not been significantly modified for
racing.
Pro-Street Conversion
(PS)
The Pro
Street Conversion (PS) class is for street legal and
licensed conversions that have minor performance alterations
for racing while still maintaining their street appearance
and drivability.
Modified Street Conversion
(MC)
The Pro Modified
Street Conversion (MC) class is for street bodied and
chassied vehicles that have been heavily modified for
racing.
DRAG VEHICLE CLASSES
Extreme
Street (XS)
The Extreme Street
(XS) class is for full bodied street vehicles that are built
as all out race vehicles. These can be custom tube chassis
or other highly modified OEM chassis type vehicles. This
class does not require vehicles to be licensed for street
use but should maintain original OEM street appearance.
Funny Car/Altered (FC) The
Funny Car/Altered class is for drag race chassis' that are
generally door-less fiberglass bodies and include but not
limited to funny cars, altered dragsters, T-bucket
dragsters, and convertible dragsters. The higher end
vehicles are normally single seat SFI spec chassis designs.
These may include kits and vehicles that are so altered or
stretched they do not fall within the other class rules or
do not look like the original OEM body it was based upon.
Dragsters (DR)
The Rail Dragsters
class includes Full-Rail Dragsters, Sand Rails, Formula
racers, SFI Spec Junior Comp Dragsters. Includes Front
Engine (FED) and Rear Engine (RED) versions.
MOTORCYCLE CLASS OVERVIEW
It is the intent of
the NEDRA Motorcycle class to encompass all two inline
wheeled electric vehicles for the purposes of classification
for 1⁄4 mile and 1/8 mile ET records into four classes:
Production Motorcycle (PMC)
It is the intent of
this class to allow production motorcycles, purchased from a
manufacturer or distributor, to be raced in direct
competition with each other.
Modified Production Motorcycle (MPC)
It is the intent of this class to allow only production
motorcycles, originally purchased from a manufacturer or
distributor, but have been altered or modified from their
original design.
Street Motorcycle (SMC) It is the intent of
this class to allow all motorcycles that are Street Legal to
compete together for records.
Drag Motorcycle (DMC) It is the intent of
this class not to limit what the geometry of the vehicle
looks like or the origin of the frame or components or
whether the vehicle is allowed to drive on the street.
OTHER CLASSES
Concept Vehicle (CV) Prototypes and
vehicles that are one of a kind and do not fall easily under
the other categories. As soon as there are two or more of
the vehicle, then it is no longer a concept vehicle.
High School (HS) Conversions of street
vehicles built and owned by
High Schools
and High School level trade schools or their sponsors.
Higher Education (ED) Street vehicles built
and owned byEducations of
higher learning such as colleges and universities and
post-highschool college level trade schools or their sponsors.

At all events
participants must meet the safety and licensing requirements of each
event as required by the track and the sanctioning body
(NHRA/IHRA/MSA/FIA etc.). For example: at NHRA sanctioned events, a
NHRA Competition License is mandatory for cars running 9.99 or
quicker (*6.39 for eighth mile) or 135 MPH or faster in the US and
Canada.
If you do not know the safety
regulations for your track you can usually find them on online. For
example, you can obtain a current copy of the NHRA rulebook from the
NHRA here:

MOTORCYCLE
CLASS OVERVIEW
It is the intent of the
NEDRA Motorcycle class to encompass all two inline wheeled electric
vehicles for the purposes of classification for 1⁄4 mile and 1/8
mile ET records. The voltage divisions and subsequent class modifier
will be the same as defined for 4 wheeled vehicles. All motorcycles
must conform to any and all safety standards required by a public
track (or private track that is specifically sanctioned by NEDRA) at
which they may race.
NHRA Competition License mandatory for cars running 9.99 or
quicker (*6.39 for eighth mile) or 135 MPH or faster.
This includes sanctioning body rules such as NHRA, IHRA, AHDRA, or
other recognized international drag racing association that might
sanction racing on a particular track. In addition all motorcycles
that compete for a NEDRA class record, except those competing solely
in PMT, must have a safety lanyard that is connected to the driver
while racing and disables power from the traction batteries in the
event the rider is separated from the vehicle. It is urged that
drivers of PMT vehicles also add this safety feature to their
vehicles. This sole modification will not jeopardize a PMT vehicle’s
status in this class.
Definitions:
-
Production means the
motorcycle can be purchased from a manufacturer or distributor
that has produced more than 10 of the same of
such vehicles.
-
Street Legal means the
motorcycle is currently registered and licensed to drive on
public streets and roadways in the state that
the owner
resides.
Production Motorcycle (PMC)
It is the intent of this class to allow
production motorcycles, purchased from a manufacturer or
distributor, to be raced in direct competition with each other.
Production motorcycles do not have to be street legal so as to allow
off road vehicles. No modifications to the vehicle are allowed which
precludes upgrade of the battery chemistry, or tires of a different
size, other than what was originally produced with the vehicle.
Modified Production Motorcycle (MPC)
It is the intent of this class to allow only
production motorcycles, originally purchased from a manufacturer or
distributor, but have been altered or modified from their original
design. Battery upgrades to a different chemistry, motor and
controller upgrades, different tires and/or wheels, and add on
fairings not originally offered as options are allowed.
Modifications to the original frame geometry are not allowed in this
class. Modified Production Motorcycles do not have to be street
legal. Wheelie bars are allowed if fitted.
Street Motorcycle (SMC)
It is the intent of this class to allow all
motorcycles that are Street Legal to compete together for records.
All requirements of the State the vehicle is licensed in, such as
head lights, turn signals and required brakes must be in place while
racing. All frames originating from ICE donor vehicles or scratch
built custom frames are allowed. All battery chemistries,
motor/controller combinations, and wheel/tire sizes are allowed as
long as they are DOT approved for street use. Wheelie bars are
allowed for use in racing the Street Class.
Drag Motorcycle (DMC)
It is the intent of this class not to limit
what the geometry of the vehicle looks like or the origin of the
frame or components or whether the vehicle is allowed to drive on
the street. Any vehicle that cannot fit into one of the previously
defined classes will be designated a DMC by race officials.
CONCEPT VEHICLE CLASS OVERVIEW
Prototypes and vehicles that are one of a
kind or do not fall easily under the other categories. As soon as
there are two or more of the vehicle, then it is no longer a concept
vehicle. Roll cage per NHRA specifications mandatory for all cars and
trucks running 10.99 or quicker or over 135 mph. NHRA Competition
License mandatory for cars running 9.99 or quicker (*6.39 for eighth
mile) or 135 MPH or faster. (more details and rules on this class available
soon)
HIGH SCHOOL
CLASS OVERVIEW
Conversions of street vehicles built and
owned by high schools or their sponsors.
Roll cage per NHRA specifications mandatory for all cars and trucks
running 10.99 or quicker or over 135 mph. NHRA Competition License
mandatory for cars running 9.99 or quicker (*6.39 for eighth mile)
or 135 MPH or faster. (more details and rules on
this class available soon)
HIGH SCHOOL MODIFIED
CLASS OVERVIEW
Conversions of street vehicles built and
owned by high schools or their sponsors that have been heavily
modified. Street legality for vehicles in this class not required.
Roll cage per NHRA specifications mandatory for all cars and trucks
running 10.99 or quicker or over 135 mph.
NHRA Competition License mandatory for cars running 9.99 or quicker
(*6.39 for eighth mile) or 135 MPH or faster. (more details and rules on
this class available soon)
Voltage Divisions
Voltage Divisions from 24 to over 600.0 volts are designed to give
racers of all voltage ranges a chance to earn a NEDRA Record.
Measured voltages allow racers with battery chemistries other then
12 volt lead acid the ability to obtain their correct voltage. The
measured voltage is not the "float voltage" but the voltage the
vehicle is measured when the float voltage has dissipated.
Basically, this would be at staging or at the starting line, where
the float charge has had a chance to dissipate.
To determine your voltage
division, simply measure your pack voltage with a digital
voltmeter to the nearest tenth of a volt. The voltage must
be measured before the run.
Voltage classes will be
listed using measured voltages. Nominal voltage is basically
the historical lead acid design voltage for that class and
just for reference purposes.
The old voltage class
conversion was a 13.2/12 factor, since very few lead acid
batteries ever go above 13.2 volts once the surface charge
has dissipated.
CLASS AND VOLTAGE CHANGE HISTORY
Effective June 1, 2006 NEDRA segmented the "A" Voltage
Division into 3 separate divisions to promote more
competition and to expand with new controller and motor
technology. The old "A" Voltage Division was 241 volts and
higher. For historical purposes, records made in the "A"
Voltage Division prior to June 1, 2006 are exempt from the
revision. Those record holders will keep their "A" division
records as they are pending a review by the NEDRA Board
since those records are historically significant.
NEDRA Street Classes went
into effect June 15, 2006.
Effective April 15, 2013
NEDRA added A4 and A5 voltage levels and added the phrasing,
"Please note that the old procedure for deriving voltage
division by counting lead acid batteries to determine
'Nominal Voltage' is no longer valid. The only valid method
for division determination is by direct voltage measurement.
The voltage measurements may be made immediately prior to
leaving the pits, in the staging lanes, or at the starting
line."
Effective Sept 27th,
2014 the vehicle class descriptions were replaced with the
Watt’s allowed table. PP&FC classed were added Record Rules
were revised..
