Turbo vs Turbo S Technical check Running costs Market prices Conclusion & recommendation
Fine-tuning beneath the bodywork

Perhaps the best all-rounder Porsche has built

With the facelift (991.2) at the end of 2015, Porsche perfected the concept of the high-performance GT. Only discreetly retouched on the outside (vertical louvres on the engine lid, three-dimensional rear lights), decisive fine-tuning took place beneath the bodywork.

The output of the 3.8-litre twin-turbo rose to as much as 580 PS in the Turbo S. But the real buying arguments for the discerning driver lie in the ancillaries: the new infotainment PCM 4.0 (at last with smartphone integration) and the "Dynamic Boost"function make the 991.2 perhaps the best all-rounder Porsche has ever built. It is faster, sharper and better connected than its predecessor, and more expensive with it.

The model hierarchy

Evolution rather than revolution

911 Turbo

540 PS · 710 Nm

  • At 540 PS, already faster than most supercars of its day
  • Often ordered with five-bolt wheels: easier wheel changes in everyday use

911 Turbo S

580 PS · 750 Nm

  • The benchmark: larger turbochargers deliver brutal thrust right to the limiter
  • Its standard equipment (ceramic brakes, roll stabilisation, 18-way seats) makes it the favourite on the used market

Specialist knowledge

Technical check: Dynamic Boost and PAA

The facelift brought new functions, but complex servicing issues too.

Engine (MA1.71) and "Dynamic Boost" +

The 3.8-litre DFI engine is regarded as extremely mature. The highlight of the 991.2 is the "Dynamic Boost"function: when the driver lifts off briefly, the throttle stays open and only the injection stops. Boost pressure is maintained, and the response when the driver gets back on the throttle is instant.

Weak points:

  • High-pressure fuel pump (HPFP): As on all direct-injection engines, a wear part. A failure leads to starting problems or limp-home mode (cost: €1,500 - €3,000)
  • VTG turbochargers: the variable geometry is brilliant, but the linkages can seize. Replacing the specific 991.2 turbochargers is expensive (parts more than €2,500 each)
PDK transmission and coasting +

The PDK was revised for the facelift (optimised shift logic, coasting in Normal mode to improve efficiency). The shift pattern on the selector lever was corrected (push = down, pull = up).

  • Reliability: Very high. But: with faults in the mechatronic unit or the sensors, Porsche often replaces the entire transmission
  • The cost trap: a replacement transmission including fitting quickly comes to €15,000 to €20,000. A used-car warranty (Porsche Approved) is worth its weight in gold here
Porsche Active Aerodynamics (PAA) +

The system of a deploying front spoiler (pneumatic) and a rear wing delivers either downforce or low drag.

  • Weak point, the front spoiler: the rubber lip is inflated pneumatically. Ageing or grounding leads to leaks. The system then no longer deploys (with a fault message)
  • Repair: replacing the spoiler unit including a check of the pneumatics costs around €2,500 - €4,000
PCM 4.0, PCCB and PDCC +
  • PCM 4.0: The new infotainment with its glass front and Apple CarPlay is an enormous plus for everyday use. Check how the touchscreen responds
  • PCCB (ceramic brakes): standard on the S. Extremely long-lived, but vulnerable to mechanical impact (wheel changes). Replacement discs cost more than €5,000 per axle
  • PDCC: The active roll stabilisation works hydraulically. Leaks are involved to put right

Market prices & investment

The 991.2 Turbo is more expensive than its predecessor, but offers considerably more practical value.

Model / conditionPrice range
Turbo (2016)€120,000 - €130,000
Turbo, well kept€130,000 - €160,000
Turbo S€140,000 - €180,000
Exclusive SeriesConsiderably more expensive (a collector's car)

Factor: convertibles are often on a par with, or slightly below, the Coupés on price. The Exclusive Series (gold metallic, carbon stripes) is in a league of its own.

The strategic conclusion from 911Finder

An extremely fast and technologically mature 911. It is the perfect one-car-garage candidate. Investment tip: A Turbo S Coupé in a classic colour with a complete service history is the safest asset. Check the PAA function and the PCCB discs meticulously.
