1989 Porsche 911

The M491 option (often called "Turbo Look", WTL, or Supersport in the UK) gave a standard Carrera 3.2 nearly all of the chassis and appearance upgrades of the 930 Turbo—without the turbocharged engine.
What the M491 Package Included
A genuine factory M491 Cabriolet typically received:
Wide Turbo front and rear fenders
Turbo "tea tray" rear spoiler (whale tail)
Front chin spoiler
930 Turbo brakes (4-piston calipers)
Turbo suspension components
Wider Fuchs wheels and tires
Turbo trailing arms and anti-roll bars
The engine remained the naturally aspirated 3.2-liter flat-six, making roughly 214–231 hp depending on market specifications.
Why 1989 Is Special
The 1989 model year is particularly sought after because it was:
The final year of the classic G-body 911.
Equipped with the desirable G50 5-speed gearbox.
Produced in relatively small numbers compared with standard Carreras.
Production Numbers
For all M491 Carrera 3.2s (1984–1989), production totaled approximately:
Body StyleProductionCoupe1,397
Targa559
Cabriolet1,684
The Cabriolet was the most common M491 body style, but genuine factory M491 cars remain rare compared with standard Carreras.
How to Verify a Real M491 Car
Look for:
Option code M491 on the factory option sticker or Certificate of Authenticity.
Matching VIN and option records.
Genuine Turbo brakes and suspension components, not just wide-body cosmetic modifications.
Original factory wide-body construction rather than aftermarket conversions. Enthusiasts often emphasize that factory M491 cars are significantly more valuable than converted cars.
Collector Interest
Today, 1987–1989 M491 cars—especially Cabriolets and low-mileage examples—command substantial premiums over standard Carrera 3.2 models because they combine:
The reliability of the naturally aspirated 3.2 engine,
The looks and chassis hardware of the 930 Turbo,
The desirable G50 transmission
