The {{convert|1453|cc|L|1|abbr=on|order=flip}} '''R''' family was produced from 1953 through 1964, and was originally manufactured at the [[Toyota Honsha plant]].

Bore and stroke was {{convert|77x78|mm|in|2|abbr=on}}.<ref name="RT20parts">Corona 1500 Parts Catalog, No.53282-67</ref> In common with new engines of the time, it was made from cast iron (both the block and the head), water cooled, used a three [[Bearing (mechanical)|bearing]] crank, 12V electrics and a side-mounted gear-driven [[camshaft]] controlling [[overhead valve]]s via pushrods in a [[Reverse-flow cylinder head|non-cross flow]] head (exhaust and [[inlet manifold]]s being on the same side of the engine).<ref name="RT20parts"/> Induction was by a twin throat down-draft [[carburettor]], the [[compression ratio]] was 8.0:1 and the total weight was {{convert|155|kg|abbr=on}}.<ref name="RT20parts"/> An [[Autogas|LPG]] version, the '''R-LPG''', was produced for the last two years.

The R engine was the Toyota engine used in the 1958 [[Toyota Crown]], the first model to be exported to the United States. ''[[Road & Track]]'' was unimpressed with the engine on its introduction, noting that it idled quietly but was "not capable of very high revolutions per minute."
