The 991 generation of the 911 Turbo S, sold from 2014 to 2019, set a new standard for supercar performance and everyday usability. Its 3.8L twin-turbo flat-six engine, paired exclusively with a 7-speed PDK transmission and all-wheel drive, delivered incredible acceleration. Standard features like rear-axle steering, Porsche Dynamic Chassis Control (PDCC), and carbon-ceramic brakes (PCCB) made it one of the most technologically advanced sports cars of its time. The 991.2 update for 2017 brought power up from 560 to 580 hp and introduced a revised infotainment system.
Collectors appreciate the 991 Turbo S for its immense, easily accessible speed and its reputation for reliability, a rare combination in this performance category. For many enthusiasts, it's also the last generation of the Turbo S to have a pure, unfiltered exhaust note before the introduction of gasoline particulate filters (GPFs). This distinction, along with its analog-style gauges and hydraulic steering feel (in the 991.1), gives it a unique place in the 911 lineage.
The market for the 991 Turbo S is strong and has seen steady appreciation. With an average sale price around $167,000, it offers blistering performance that rivals more expensive exotics. Later 991.2 models typically command a premium for their updates and increased power, while cars with desirable options like the front-axle lift system and Burmester sound system are always in high demand.
Buying Tips
- Get a DME report to check for over-revs. Range 1 and 2 are common, but anything in ranges 3-6 can indicate serious mechanical abuse.
- Verify the service history, ensuring the PDK transmission fluid has been changed on schedule (every 6 years or 60,000 miles).
- Carefully inspect the standard carbon-ceramic brake rotors (PCCB) for chips or cracks, as a full replacement can cost over $20,000.
- Check for common 991 interior issues like delaminating door panel inserts, a frequent problem that is costly to fix properly.
- Ask about aftermarket engine tuning. While common, aggressive tunes can put extra strain on the engine and drivetrain, so a stock car often represents a safer long-term purchase.
