Modern Engine - HistoricTax Exemption
Discussion
Hi, If I where to buy a classic car, over 40 years old (tax exempt) then I were to swap out the engine with a modern cleaner engine, once DVLA were informed would the car still be tax exempt? or am I completely wrong with this? I can't seem to find any information/answers to my question on-line. If this is a glaringly obvious answer then please be gentle with your replies.
Thanks in advance

The 8pt rule decides.https://www.gov.uk/vehicle-registration/radically-...
For the forthcoming MOT exemption, a much looser rule is looking likely - +15% power-to-weight being the cutoff in the current draft.

And what is not yet clear is whether this will be applied retroactively i.e. to cars modified under the existing rules.https://www.gov.uk/vehicle-registration/radically-...

Those cars that don't meet the requirement for the exemption will just continue as per now - they'll need an MOT annually.

Sorry, but surely cars modified under the 8 point rule after 1988 are currently exempt from MOTs if they meet the test - so it's not going to be the same? Those cars that don't meet the requirement for the exemption will just continue as per now - they'll need an MOT annually.

When I fitted a ~1998 engine to my ~1989 Peugeot 205 GTI the car was tested during the MOT on 1989 figures - was funny seeing how it always sailed through the emissions tests even with a decat.Thanks in advance

I would expect the same to be true no matter how old the chassis - the age of the car is related to the number plate, not the engine under the hood.
Obviously still the points system applies for very extensive modifications.

Anything 1960-40yo currently needs an MOT. If it meets this new test, then it won't. If it fails, then no change.
As far as the MOT is concerned, the emissions test is based on whichever is older, chassis or engine.
As for the engine swap and "historic" status, how would they know the age of the engine? You only need to state the new capacity and the engine number (unless the rules are different for the historic class).
Anyway, if the vehicle is not already registered, the engine is only worth 1 point, and once it's registered you can do what you like.
