The end of an era

The last true naturally aspirated Carrera

The Porsche 911 of the 991.1 series (built from the end of 2011 to the end of 2015) was a complete new design with a longer wheelbase, a wider track and an innovative aluminium-steel body. But its most important feature today is a historical one: it kept the naturally aspirated engines .

The Carrera used a new 3.4-litre DFI engine (MA1.04) with 350 PS, the Carrera S a further developed 3.8-litre DFI engine (MA1.03) with 400 PS. Because its successor (991.2) moved to turbo engines, the 991.1 counts as the last true Carrera with linear power delivery and an unadulterated sound. It is not affected by the IMS problems of the 997.1 era, but still calls for a detailed technical inspection.

The way into the world of the modern classics

911 Carrera (3.4 litres)

350 PS · 390 Nm · MA1.04

  • An extremely rev-happy engine that has to be worked
  • Regarded as particularly durable
  • Ideal for purists who want to rev the engine out without losing their licence in the process

911 Carrera S (3.8 litres)

400 PS · 440 Nm · MA1.03

  • Considerably more punch from low revs
  • Larger brakes as standard (red callipers)
  • Often better specified (PASM as standard)
  • The more popular choice for investors

Gearbox options

TransmissionThe assessment
PDK (seven-speed)Fast, efficient and very common on this model
Manual (7-speed)The world's first 7-speed manual gearbox. Seventh is a pure overdrive for saving fuel. The shift feel is sometimes criticised as notchy, but it is extremely sought after today (a factor in value growth)
Specialist knowledge

Weak points: COV, PDK and interior

The 991.1 is solid, but it has specific ailments that can become expensive.

Engine (MA1) and changeover valves (COV) +

The engines are regarded as robust. Bore scoring is extremely rare (unlike on the 997.1), but with neglected servicing it cannot be ruled out entirely (a borescope inspection if there is any suspicion or any noise).

  • Changeover valves (COV): The vacuum system controls the exhaust flaps, the heating and the sound symposer through small changeover valves. These fail in droves. Symptoms: the heating does not work, the sports exhaust does not switch, a "cooling system fault" message
  • High-pressure fuel pump (HPFP): can fail, which leads to limp-home mode or a standstill. Cost around €1,500 - €3,000
  • Maintenance: Ignition coils and plugs are subject to thermal wear. The correct oil quality is decisive
PDK transmission and manual +

The PDK is efficient, but carries a financial risk.

  • PDK sensors: a known failure is the speed sensor in the transmission. Porsche often replaces the entire unit (cost more than €15,000). Specialists can replace the sensor on its own (around €3,000 - €5,000)
  • Leaks: the PDK tends to weep at the oil pan (plastic)
  • Manual: Generally reliable. Clutch wear is normal
Body, door panels and recalls +

The interior ailment: a classic 991.1 problem is door trim panels coming away (warping). The adhesive lets go at the top edge next to the window and the panel bows upwards. Replacement is expensive (around €1,500 per side).

Important recalls (check these):

  • May 2013: cracking of the rear silencer (3.4 litres without the sports exhaust system). The tailpipe can be lost. Remedy: replacement of the silencer
  • November 2014: a weak bonnet latch striker (the lid can spring open while driving). Remedy: replacement
  • January 2017: the fastening screws on the fuel rail can work loose (fuel can escape, with a risk of fire). Remedy: replacement
Before buying, always check that every recall has been carried out on the car.
PDCC, steering and electronics +
  • PDCC (roll stabilisation): optional. The hydraulic system is complex. Leaks or pump failures run into thousands
  • Steering: the electromechanical steering (EPS) is reliable, but offers less feedback than the old hydraulic system
  • PCM 3.1: the infotainment can fail (a boot loop caused by a failed hard disk). It can often be repaired (an SSD upgrade)
  • Sunroof: tends towards rattles and leaks

Running costs & risk calculation

Market prices & investment

The 991.1 benefits enormously from the "last naturally aspirated" premium.

Model / mileagePrice range
Carrera (more than 100,000 km)€65,000 - €70,000
Carrera (under 100,000 km)€75,000 - €95,000
Carrera S (more than 100,000 km)€75,000 - €80,000
Carrera S (under 100,000 km)€85,000 - €110,000

Factor: manuals are rare and, depending on the buyer, can command a premium. Convertibles are often a little cheaper than Coupés.

The strategic conclusion from 911Finder

A modern, reliable and comfortable 911 with the coveted naturally aspirated character. It is the perfect bridge between the classic and the modern. Investment: Always check the recall history and whether the door panels are coming away. A well-kept 3.8 S manual is the best asset.
