I know the Metropolitan Nash was built in England and shipped to the USA from 1953 through 1962. It was originally the Hudson Nash.
However, I met a person today that swore the engine in the Metropolitan Nash was the exact same engine as in the MG.
I have not been able to prove or disprove this.
Does anyone know positively the answer to this question? Was it the same engine, or one that was just made by the same company?
No real reason to know, just curious.
Oil leak?? What oil leak? That puddle under the car is just sweat from all that horsepower!!

Most of them have a MG B series 1500s same as a early MGA, early cars had the B Series 1200, that was also used in Austin A40. The B series started life as the 1200cc engine and grew from there. My mom had one when she was pregnant with me, my dad got rid of it when he saw one in a bad accident.

Google is your friend https://en.wikipedia.org/wiki/Nash_Metropolitan
It had a B series engine, so yes, it's antededants were the same as the MGA/MGB. Wolsley, Riley, Morris, Austin etc etc. (but only as 1200cc and 1500cc units. A brave man could fit a 1.8 MGB engine)
.... many, many cars later I bought an MGB.

Robert-
Yes, an 1800cc three-main-bearing 18G or 18GA B-Series engine could be adapted to go into a Metropolitan. Unfortunately, the Metropolitan three-synchro transmission has the earlier small shaft and bears, so it would have a pretty rough life. However, with a bit of mixing and matching of the shift towers and their related parts, a three-synchro transmission from an MGB could be made to work in a Metropolitan without too much hassle. Its been done several times before. Installation of the later five-main-bearing engine and its four-synchro transmission would be a lot more work, but possible if you have the skills, the time, and the patience to do it.

The Metro had a single down draft carb. The 1200 had no provision for an oil filter. They were actually fun to drive. I would own one if one can be found that is not melting to the ground with rust.

Well, as they say, you learn something new everyday.
I never knew the connection between the Nash and our MG's.
Thanks for the information.
These were before my time, but I always thought they were just ugly enough that I liked them

I believe on the one I saw he went to the effort to use a full sync transmission. I think he said the donor car was early 70s, and the seats looked that vintage.

The Metropolitan was truly an economy car of the 1950s. Styled by none other than Pininfarina himself, many called it "the flying soapdish". I always wanted to do one in its classic 1950s two-tone color scheme of ivory White and Aqua.

A youngish guy here in our small town has one - a red Metropolitan convertible that appears to be in wonderful condition. It comes out of his garage now and then - sunny days only - and putters around town.
Memories: a friend in high school 1959-60 thereabouts, had a Yellow/White coupe. He liked to say it "has an MG engine." We'd go on road trips but his two passengers had to alternate between front and rear seat as the back was only suitable for a small child....half an hour in it would bring a reasonably sized teen to tears. And no seat belts anywhere.

And, one hopes, also upgrade the brakes and perhaps handling!

The original A40 Devon/Somerset 1200 was not a B series engine. The B series engine, while it wasn't radically different from the A40 engine, was designed from scratch.
True - Wiki has a good write up - lots of commonality of bits carried over but essentially different engines.
Quote:
Austin realised that eventually they would need an engine that could power many of its forthcoming medium-sized cars, and this would require an engine of at least 1500 cc capacity. Since the A40 Devon engine could not have its capacity enlarged, a new engine needed to be designed and built.
The design of this new engine commenced around January 1952, and was designated as the "B" series. The first production version of the B series retained the same 1200cc capacity as the A40 engine and, superficially, appeared to be identical, with the same valve gear, same cylinder head design, same positioning of its ancillary parts (many of which were interchangeable with the older engine) and so on. But the B-series block and head were slightly larger in both length and width and the block had thicker cylinder wall castings making the new engine heavier than the A40 motor. This was to allow room for enlargement of the cylinder bore to provide the larger capacities foreseen by BMC.

So there was a 1200 cc precursor engine and then also a B series 1200 engine but they aren't the same.
