Porsche 911 Turbo S 993
The Porsche 993 Turbo S stands as the ultimate expression of the air-cooled 911, a car that marks the end of an era with the most powerful and refined version of Porsche's iconic rear-engine sports car. Built in extremely limited numbers during 1997 and 1998, the Turbo S represented everything Porsche had learned in three decades of turbocharging the 911.
The 993 Turbo S used a development of the standard 993 Turbo's 3.6-liter twin-turbocharged flat-six engine. Through larger KKK K24 turbochargers (compared to the K16 units in the standard Turbo), revised ECU mapping, a modified exhaust system, and additional cooling, Porsche extracted 450 hp -- an increase of 42 hp over the standard 993 Turbo's 408 hp. Torque rose to 585 Nm (431 lb-ft), delivered through Porsche's proven all-wheel drive system and a 6-speed manual gearbox.
Performance was extraordinary for the late 1990s. The Turbo S could reach 60 mph in approximately 3.6 seconds and had a top speed of 186 mph (300 km/h). These figures put it in direct competition with supercars costing far more, while the 993's everyday usability and legendary Porsche build quality made it a practical daily driver.
The Turbo S was visually distinguished from the standard Turbo by its carbon fiber front bumper trim, yellow-tinted headlights (European models), carbon fiber rear wing with air scoops, and Turbo S-specific interior with carbon fiber trim and exclusive leather. The car sat on 18-inch hollow-spoke wheels designed to reduce unsprung weight.
Inside, the Turbo S featured a full leather interior with carbon fiber accents, electrically adjustable sport seats, and a numbered plaque denoting its place in the production run. The attention to detail was remarkable, with every surface trimmed in the highest quality materials.
Porsche built only 345 examples of the 993 Turbo S worldwide -- 183 for European markets, 160 for North America, and a handful for other regions. This extreme rarity, combined with its status as the last air-cooled Turbo, has made the 993 Turbo S one of the most collectible modern Porsches.
The significance of the 993 Turbo S extends beyond its performance figures. It represents the absolute zenith of Porsche's air-cooled engineering, a technology that defined the 911 for 35 years. When Porsche transitioned to water-cooled engines with the 996 generation in 1999, many enthusiasts mourned the loss of the air-cooled character. This has driven extraordinary appreciation in value, with clean examples now commanding $500,000 to $900,000.
The 993 Turbo S delivers a driving experience that combines explosive acceleration with a mechanical connectedness that water-cooled 911s struggle to match. The sound of the air-cooled flat-six at full boost, the progressive feel of the analog controls, and the knowledge that this was the final, finest example of a dying breed create an emotional resonance that few cars can equal.
Ensure the car is a genuine Turbo S, not a standard Turbo with aftermarket modifications. Check for the numbered interior plaque, carbon fiber trim, and Turbo S-specific features. Service history from Porsche or recognized specialists is essential. The air-cooled engine requires diligent maintenance. Verify turbocharger condition and check for oil leaks. All-wheel drive system components are expensive if they fail. Low-mileage examples command the highest prices, but well-maintained higher-mileage cars offer better value. North American-spec cars with catalytic converters produce slightly less power than European versions.
Built in limited numbers during 1997-1998 as the final air-cooled 911 Turbo variant. Total production was approximately 345 units: 183 for Europe, 160 for North America, and a small number for other markets. Each car received a numbered plaque. The Turbo S used larger turbochargers and revised tuning compared to the standard 993 Turbo.
