(a) Vehicles produced from glider kits and other glider vehicles are subject to the same standards as other new vehicles. Note that this requirement for the vehicle generally applies even if the engine meets the criteria of paragraph (c)(1) of this section. For engines originally produced before 2017, if you are unable to obtain a fuel map for an engine you may ask to use a default map, consistent with good engineering judgment. (b) Section 1037.601(a)(1) disallows the introduction into U.S. commerce of a new vehicle (including a vehicle assembled from a glider kit) unless it has an engine that is certified to the applicable standards in 40 CFR parts 86 and 1036. Except as specified otherwise in this part, the standards apply for engines used in glider vehicles as follows: (1) [Reserved] (2) The engine must meet the criteria pollutant standards of 40 CFR part 86 or 40 CFR part 1036 that apply for the engine model year corresponding to the vehicle's date of manufacture. (3) The engine may be from an earlier model year if the standards were identical to the currently applicable engine standards. (4) Note that alternate standards or requirements may apply under § 1037.150. (c) The engine standards identified in paragraph (b) of this section do not apply for certain engines when used in glider kits. These engines remain subject to the standards to which they were previously certified. (1) The allowance in this paragraph (c) applies only for the following engines: (i) Certified engines still within their original useful life in terms of both miles and years. Glider vehicles produced using engines meeting this criterion are exempt from the requirements of paragraph (a) of this section if the glider vehicle configuration is identical to a configuration previously certified to the requirements of this part 1037 for a model year the same as or later than the model year of the engine ## Nearby sections - [40 C.F.R. § 1037.601 (2026) § 1037.601 General compliance provisions.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_601.md) - [40 C.F.R. § 1037.605 (2026) § 1037.605 Installing engines certified to alternate standards for specialty vehicles.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_605.md) - [40 C.F.R. § 1037.610 (2026) § 1037.610 Vehicles with off-cycle technologies.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_610.md) - [40 C.F.R. § 1037.615 (2026) § 1037.615 Advanced technologies.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_615.md) - [40 C.F.R. § 1037.620 (2026) § 1037.620 Responsibilities for multiple manufacturers.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_620.md) - [40 C.F.R. § 1037.621 (2026) § 1037.621 Delegated assembly.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_621.md) - [40 C.F.R. § 1037.622 (2026) § 1037.622 Shipment of partially complete vehicles to secondary vehicle manufacturers.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_622.md) - [40 C.F.R. § 1037.630 (2026) § 1037.630 Special purpose tractors.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_630.md) - [40 C.F.R. § 1037.631 (2026) § 1037.631 Exemption for vocational vehicles intended for off-road use.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_631.md) - [40 C.F.R. § 1037.635 (2026) § 1037.635 Glider kits and glider vehicles.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_635.md) - [40 C.F.R. § 1037.640 (2026) § 1037.640 Variable vehicle speed limiters.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_640.md) - [40 C.F.R. § 1037.655 (2026) § 1037.655 Post-useful life vehicle modifications.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_655.md) - [40 C.F.R. § 1037.660 (2026) § 1037.660 Idle-reduction technologies.](https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_660.md) --- Source: Frix Law Library, https://www.frixlaw.com/law-library/statutes/CFR_T40_P1037_S1037_635.
