Low Volume.Replica Vehicles

California Air Resources Board staff is now seeking input on ways to certify engines intended for use in specially produced motor vehicles. A specially produced motor vehicle is a turnkey light-duty vehicle or light-duty truck produced by a low-volume manufacturer and that is intended to resemble the body of another motor vehicle that was manufactured not less than 25 years before the specially produced motor vehicle. The specially produced motor vehicle is to be treated and sold similar to any other new vehicle sold to the public.

Existing laws and procedures only address specially constructed vehicles built for private use, by an individual, and not intended for resale. These are: Senate Bill (SB)100 (Health and Safety Code section 44017.4) and California Certification Procedures For Light-Duty Engine Packages for Use in Light-Duty Specially Constructed Vehicles, sections 2210, 2211, 2212, 2213, 2214, 2215, 2216, 2217, and 2218, title 13, California Code of Regulations.

SB 100 allows up to 500 specially constructed vehicles per year to be assembled and registered for on-road use, the individual builder/owner is given the option to choose the vehicle’s make and model year based on the representation of how the vehicle looks or its engine configuration. These vehicles are exempt from the state’s smog check requirements.

“California Certification Procedures For Light-Duty Engine Packages for Use in Light-Duty Specially Constructed Vehicles” is designed for those individual builders/owners who either decided that their vehicle does not qualify as an SB 100 vehicle or is unable to receive one of the 500 vouchers allocated by the Department of Motor Vehicles (DMV). These specially constructed vehicles are registered and bi-annually smog check tested based on the current calendar year.

For both processes mentioned above, individual builders/owners must have the following done before their vehicle is allowed to be driven on the state’s highways: DMV, to get initial paperwork started and be given a temporary on-road driving sticker for up to 3 months, California Highway Patrol, to get a vehicle identification (VIN) number or a background check on the current VIN number, light and brake inspection, conducted by a certified inspection shop, Bureau of Automotive Referee Inspection, to review all paperwork including the build sheets needed for an SB 100 voucher, vehicles not using the SB 100 program are smog inspected and tested according to the current calendar year, and then back to the DMV to turn in required paperwork and receive plates and stickers.

The California Air Resources Boards’ eventual procedures to certify engines intended for use in specially produced motor vehicles will help low volume manufacturers who intend to build vehicles as part of the new federal law enacted on December 4th 2015. The federal specially produced low volume legislation allows for the use of an engine covered by a California Air Resources Board Executive Order for the model year in which the specially produced motor vehicle is produced.
