The 964 Carrera RS (Standard) was introduced by Porsche for model year 1992 specifically for the European market as a lightweight, high performance version of the 964 Carrera 2. It featured a revised version of the standard 3.6 liter engine, titled M64/03 internally, with an increased power output of 260 bhp (194 kW; 264 PS). The RS does not look much different from the other 911 models of the period but its weight is reduced and power increased. True to its racing spirit, the Carrera RS featured bucket seats and thinner materials, but lacked power windows, air conditioning, air bags, and other creature comforts common in the Carrera 2, reducing weight by approximately 345 lbs. Approximately 1,910 Carrera RS were built in Standard (a/k/a Basic, or Lightweight) form, another 290 samples were the race-ready 964 Carrera RS N/GT, and approximately 76 were built in Touring specification (M002), adding back many of the creature comforts found in the standard Carrera 2. Related, yet considered different models are the US-specific RS America, and the later, ultra-limited production sibling, the 964 Carrera RS 3.8.
