Buying a Porsche 991 (2012–2019)

The 991 is longer, wider and more refined: electric power steering, a seven-speed manual, and a much bigger choice of models.

Buying a Porsche 991 (2012–2019)

The 991 is longer, wider and more refined: electric power steering, a seven-speed manual, and a much bigger choice of models. The 991.1 (2012–2016) keeps naturally aspirated 3.4 and 3.8 engines; the 991.2 (2017–2019) Carrera moved to a 3.0 twin-turbo with far more torque.

The GT cars define the generation. The 991.1 GT3 was PDK only; the 991.2 GT3 brought back the manual with a 4.0-litre engine, plus the Touring, the 911 R, the GT2 RS and the Speedster.

What to look for

  • 991.1 GT3 engines

    Early cars were recalled and many had engines replaced by Porsche. Check what was done and that the paperwork is with the car.

  • Over-revs

    Manual cars store over-rev history in the engine computer. Read it with a factory scan.

  • Front lift and PDCC

    Check every hydraulic option works; they are costly to fix.

Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US. Your car's own maintenance booklet is the final word. HBi Auto's recommendations for cars that are tracked, driven hard or stored are being added by our service team.
