Porsche 991 911

Buyer's Guide

Porsche 991 911

2012–2019

Overview

The 991 is a big, fast, sophisticated 911: longer and wider than the cars before it, with electric steering and, from the 991.2 on, turbocharged Carreras. Purists prefer the naturally aspirated 991.1 for its sound and throttle response; the 991.2 has more torque everywhere. There's no IMS bearing, and the common problems are minor next to older 911s, but it's still a modern Porsche, and PDK and PASM work isn't cheap. Service history matters more than mileage.

Which One to Buy

Carrera / Carrera S (991.1)

2012–2016

Naturally aspirated: a 3.4L with 350 hp or a 3.8L with 400 hp. The purist's choice, with a high-revving character.

Desirability High

Carrera / Carrera S (991.2)

2017–2019

Turbocharged 3.0L with 370–420 hp. More torque everywhere, and a different character.

Desirability High

All-wheel drive, with the wider rear body. More planted in all conditions.

Desirability High

GT3 / GT3 RS

2014–2019

The track-focused GT3s, with naturally aspirated engines making 475–520 hp. PDK only on the 991.1 GT3; a manual returned on the 991.2. Exceptional driver's cars.

Desirability High

Turbo / Turbo S

2014–2019

Twin-turbo, 520–580 hp, and all-wheel drive. Staggering acceleration with everyday comfort.

Desirability High

GT2 RS

2018–2019

700 hp from a twin-turbo 3.8L, rear-wheel drive, and built for the track. Priced like the collectible it is.

Targa 4 / 4S

2014–2019

The power-operated Targa roof, with all-wheel drive only. Elegant, if heavier.

Pre-Purchase Inspection
