Porsche 930
Porsche discontinued the 930 after model year 1989 when its underlying "G-Series" platform was being replaced by the 964. In that year, Porsche introduced the 930 Speedster, a variant featuring body style akin to the 356 Speedster, the Speedster featured a humped rear end with a "double bubble" roof storage compartment and a short, raked windshield along with a manually operated soft top. Only a handful of examples were produced making it one of the most rare 930 variants alongside the slantnose. The 1989 models were the first and last versions of the 930 to feature the G50 five-speed manual transmission. A turbo version of the 964 officially succeeded the 930 in 1991 with a modified version of the same 3.3 litre flat-six engine and a five-speed transmission.
