The Porsche 356 B T6 Coupe was built on the success of its very popular predecessor: the Porsche 356 B T5 Coupe. In late 1961, Porsche introduced the T6 updates and produced the first run of about 1,400 cars in that same year, all of them through Reutter, the traditional coach builder for 356 Coupes in the past. Nonetheless, in 1962 Porsche reached out to Karmann, the company which had produced the not-so-succesful Notchback Coupe to produce the regular Coupe variant. In total, the 356 B T6 Coupe production increased 50% over the T5 Coupe production, and saw four times as many cars built as any other 356 B T6 variant. After a total production run of approximately 12,000 cars, Porsche decided to make a few structural and technical changes to the T6 Coupe and launched the fourth generation (and last) Coupe: the Porsche 356 C Coupe.
