In 1984, Porsche replaced the SC with what proved to be the final variant of the G-Series 911, the Carrera 3.2. The primary upgrade was the engine; a displacement increase from 3.0L to 3.2L, an updated fuel injection/ignition controller, and other upgrades brought power up to 231hp (207hp for the US) from 204hp (180hp in the US). In addition, the usual interior and exterior adjustments kept the model up to date with buyer’s expectations.
While the rest of the world could still purchase a 911 Turbo in 1984, Porsche had pulled the car from North American shores several years prior due to emissions requirements. Therefore, to appease the NA buyers and offer a model in between the standard car and the Turbo, the company announced the M491 package. Commonly called the „Turbo-Look“ package (and referred to as the Supersport package in the UK), buyers who requested the M491 package essentially received a 911 Turbo without the engine. Wide rear fenders, heavier-duty suspension components, high-performance brakes, and wider wheels ensured the package was far more than a simple appearance upgrade.
Initially, the M491 could only be ordered by special request as a Coupe, but for 1985, one could specify the package as a regular production option for any of the three available body styles. When the 911 Turbo re-appeared in US order books for 1986, M491 orders plummeted, with some documentation suggesting as few as eight ‚Turbo Look‘ Cabriolets were produced for the US market in 1986. All told, only a few thousand 911s were produced with the ‚Turbo-Look‘ package.
