Morgan Plus Four Plus (+4+) at the Josefuv Dul Car Show, Liberecky kraj, Bohemia(CZ), 2015

The Morgan Plus Four Plus (a.k.a. the +4+) was introduced in 1963, but only 26 were built, making this car one of the rarest ones at the Josefuv Dul show. In spite of Morgan usually building cars deliberately designed to look pre-World War II, this one featured more or less modern styling for 1963, arguably copying a bit from Jaguar.

The engine was only a 2138cc I-4 with 110 horsepower, which had actually been sourced from Triumph, rather than built in-house. In fact, many Morgans over the years had Triumph engines before Truimph got out of car building. In spite of Triumphs and Morgans of that era not being very fast (more recent Morgans, in spite of their appearance, have often been very fast, with 0-60 times under 5 seconds), the +4+ was considered good for its day (I haven't been able to find specific data for the +4+ specifically, though). Its low production (due to low sales, rather than a deliberate limit) remains a mystery to automotive historians. It may have been that Morgan buyers specifically wanted a retro car, and the +4+ wasn't it.
