Kit cars 4.10 Kit cars and reconstructed classic cars undergoing IVA will not be required to meet WLTP (World-wide Limited Test Procedures), given that at present they are not required to meet NEDC or the latest EU standards. Instead they are tested to age-appropriate MOT standards,on the basis of the date of manufacture or first use of the engine. 4.11 We are proposing that for kit cars, compliance with the MOT emissions standards current at the date of registration will be required,despite the use of an older engine.In other words the current relaxation for emissions according to the age of the engine will no longer apply. 4.12 Reconstructed (restored) classic cars undergoing IVA will not be required to meet the latest MOT standards, as long as the appearance of the vehicle is broadly unchanged and the engine is of the same capacity as that supplied with the vehicle when it was new. 4.13 When new vehicles were first required to be fitted with catalytic converters around 1992 (Euro 1 emissions standard), kit car makers typically used older engines which were not fitted with catalytic converters, hence the justification for age-appropriate testing of emissions based on date of engine manufacture or first use. The majority of the fleet is now vehicles up to 25 years old whose engines are fitted with catalytic converters, providing plenty of choice to the kit car builder.
