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that the old procedure for deriving voltage division by counting lead acid batteries to determine 'Nominal Voltage' is no longer valid.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

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

NEDRA Record Holders
3017 N 2nd St
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 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:

Street Production Motorcycle (SPM)
This class is for street legal production motorcycles, purchased from a manufacturer or distributor, to be raced in direct competition with each other.

Modified Production Motorcycle (MPM)
This class is for production motorcycles, originally purchased from a manufacturer or distributor, but have been altered or modified from their original design.  Motorcycles in this class must be recognizable as originating from the original OEM vehicle but do not have to be street legal.

Street Conversion (SCM)
This class is for all converted motorcycles that are street legal to compete together for records.  ICE conversions can race in this class.

Modified Conversion (MCM)
This class is for converted motorcycles or ATV's that have been altered or modified so they are not street legal.

Drag Motorcycle (DMC)
It is the intent of this class to not limit the appearance of the vehicle 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 DMC.

 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: 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.

In addition to requirements outlined in the "watts up" table, all motorcycles must conform to any and all safety standards required by a public track (or private track specifically sanctioned by NEDRA).  

 1.0 Motorcycle classes are broken down into five types: Street Production, Modified Production, Street Conversion, Modified Conversion and Drag Motorcycle, each with different levels of modifications allowed.

 2.0 NEDRA recommends that all riders wear leather one or two-piece suits, Snell approved full-face helmets, substantial boots and leather gloves.

 3.0 Use of back and chests protectors and/or inflatable “air bag” equipment is recommended.

 4.0 “Production” means the motorcycle can be purchased from a manufacturer or distributor that has produced more than 10 of the same vehicles.

 5.0 Racers must consult the “NEDRA Handbook for additional construction details.  This explains NHRA and IHRA Electric Powered Vehicle rules.

 6.0 Voltage divisions will be the same as that defined for 4-wheel vehicles.

 7.0 Street Legal means the motorcycle is currently registered and licensed to drive on public streets and roadways in the state in which the owner resides.

 8.0 Motor Stop Switch: A positive “off” switch that can be operated without removing hands from the handgrips (typically wired to disengage a contactor).

 9.0 Lanyard: A tether attached to the rider so that a motor contactor will open should the rider separate from the motorcycle. The tether must have metallic ends.

 10.0 Safety Contactor: An electrical safety contactor that deenergizes the traction system.
       The use of solid state switches is prohibited.
          If controlled by an external low-voltage circuit, the default (deenergized) position must be “open”.
          It may not be routinely closed used to open or close under load.
          It must be separate from any contactor used to throttle the vehicle or precharge the controller. 

11.0 Wiring Standard: All wiring, switches, fuses, circuit breakers, contactors must have a DC voltage rating greater than or equal to the voltage to which they will be exposed.

 12.0 Live Vehicle Indicator: A red marker or light that is clearly visible when traction system is energized.

 13.0 E-Stop: An externally activated switch installed on the rear of the vehicle and clearly  marked to indicate “off” position.
          If push-button type, “in” must be “off”.

         Traction battery pack must be physically disconnected when this switch is in the “off” position.

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..
