Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Euro 3 v Euro 4

Asking on someone else's behalf; is there an easy way to tell at a glance if a car is Euro 4 or Euro 3?
Some discussion of how to bring Euro 4 up to Euro 3 (or beyond) spec and power could be really useful too.

The obvious difference is a Euro 4 M3W has extra cats in the exhausts. There are others but they may have been changed by the owner or before delivery, air intake, ride height for example.

Thanks Roger, much appreciated and have passed the info onwards.
I have to confess that I hadn't looked very deeply at the differences as they didn't seem to apply to me!

Comprehensive info on changes below.




Most obvious difference to me would be the front uprights which have the stub axles placed lower on Euro 4 models to raise the front. They are interchangeable.

There was an option to reverse the ride height change so the front uprights might not be such an obvious indicator. Also there were options to shorten the rear light stalks and to delete the air intake “moustache”

I know at least one Euro 3 car that had the front raised for a charity tour around India using Euro 4 uprights. It would seem likely given Rogers post there would be no shortage of these

My 2019 is the Euro3 which is lower thn the Euro 4. The easiest way to tell about the suspension is that there are two sets of rear shock mounting points on the swingarm, one of which raises the vehicle in the rear. There are different front uprights also but they are not as easily identified. I am sure between the info that other have provided and this it would be easy to identify to a prospective buyer or second owner.

Was the Euro 4 ever sold in the UK?

I have looked at a lot of used Morgan 3's in the UK and they all seem to be Euro 3? Even this one that claims to be the last car to leave the factory in 2022 https://www.carandclassic.com/auctions/2022-morgan-3-wheeler-gL2Ex4

Euro 4 M3W’s were sold in the UK but are in the minority, engine management issues saw them revert to Euro 3.

My car was shipped from the factory in May of 2022, so I'm not sure why that car is the "last to leave the factory". I have pictures of my US bound car with several others that were shipping in May. The last UK car? They did focus on the export non-EU cars in 2022 but they kept building them well into the summer of 2022 with the extra motors they got from S&S.
