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 600 volts and over. 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that the old procedure for deriving voltage division by counting lead acid batteries to determine 'Nominal Voltage' is no longer valid.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.

·            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.

·            Send Race Form and copy of the two valid time slips to:

NEDRA Recordkeeper

2985 Dutton Ave #3

Santa Rosa , CA 95407

 

or email to:

recordkeeper@nedra.com

 

or Fax to:

707-581-1860

 

 

*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 (last revised 9/27/14)

NEDRA Classes

 

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 or their sponsors.

High School Modified (HM)
Street vehicles built and owned by high schools or their sponsors that have been heavily modified.

  List of definitions

Heavy Duty or modified must be by original manufacturer for specific year of manufacture
Aftermarket means non-OEM supplier
Aftermarket upgrade non-OEM supplier upgraded from original part specifications
OEM means Original Equipment Manufacturer
OEM part includes replacement part meeting same specifications
"NHRA or Equivalent" means comparable organizations such as IHRA, MSA, FIA

 

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: http://store.nhra.com/shop-by-department/membership/

 

 

 

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:

  1. Production means the motorcycle can be purchased from a manufacturer or distributor that has produced more than 10 of the same of
    such vehicles.
  2. 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 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..
