Introduced in late 1994 for the 1995 model year, the standard 911 Carrera of the 993 generation was fitted with a development of the M64 3.6-liter flat six that had been found in the prior 964 generation. With a redesigned exhaust system and new hydraulic lifters, the engine produced 272 horsepower. For the 1996 model year, a Targa variant was introduced, and a variable intake runner system (called VarioRam) was added to the entire Carrera lineup, bumping horsepower to 285. Approximately 23,000 coupes were built, 15,500 cabriolets, and 4,500 Targa's, in both manual and automatic (Tiptronic) transmission.  Overlapping with the last year of production, it was replaced by the 911 Carrera of the 996 generation for model year 1998.
