Porsche 911 (991) (2011 – 2015) At A Glance

5/5

+All-new 911 is lighter and faster. Retains familiar shape with a new interior. Six speed PDK or seven speed manual transmissions. Still the definitive sports car.

-Starts at more than £70,000.

Insurance Groups are between 49–50
On average it achieves 74% of the official MPG figure

The styling may be traditional 911 but this version of Porsche's iconic sports car - designated as the 991 - is a big step forward. There’re a few fairly obvious changes from the previous generation model, the roofline is lower and the tail lights are smaller, but the meat of the changes are under the skin.

The wheelbase has been increased by 100mm to improve stability while the body and chassis are made from more lightweight materials. There are a host of aerodynamic tweaks to reduce lift and increase downforce while maintaining a low drag coefficient, which is good for fuel economy.

The engine remains, as always, a flat-six – the Carrera model gets a 3.4-litre 350PS unit while the Carrera S gets a 3.8-litre engine producing 400PS.

The lower powered engine, when fitted with a PDK gearbox, gets the 911 from 0-62mph in 4.6 seconds, and that’s cut to 4.4 seconds when the optional Sport Chrono Pack is specified. The 3.8-litre Carrera S is slightly quicker to 62mph, taking 4.3 seconds, or 4.1 seconds in Sport Plus trim.

To enhance handling and dynamics over the outgoing model there’s a wider front track, a new rear axle and a new electro-mechanical power steering system. Carrera S models get Porsche Dynamic Chassis Control (PDCC), which reduces body roll through bends, meaning the tyres are always in the optimal position to keep the car gripped to the road.

Inside the cabin there are traditional 911 features, like the instrument cluster with five dials, coupled with modern technology, which includes a high resolution multi-function display.

Standard equipment on all models includes leather upholstery, automatic climate control, 7-inch touch screen infotainment system with sat-nav, MP3 connectivity and Porsche Stability Management.

Why does my Porsche 911 991 rattle?
"I bought a six month old Porsche 911 (991) model Carrera from a Porsche main dealer in September 2015. Mechanically the car is perfect, but there is an abundance of creaks and rattles from the interior - mainly door cards and back seats, although the dash rattles a bit too sometimes. I rarely drive the car but when I do the noise makes me not want to. Do you know if this is a warranty item or something I need to fix myself? The car was originally registered in March 2015 and has covered 14,000 miles."
Reads as if it has been crashed, repaired and re-assembled. Worth getting that checked by a bodyshop. If all original, then back to the dealer and if he won't fix it then it's a matter of finding a local car upholsterer and trimmer.

Porsche 911 or BMW 6 Series?
"I have been offered a four year old Porsche Carrera Cabriolet with only 7000 miles, excellent condition, but £52k original cost with extras £90k. Is a BMW 6 Series Convertible a better buy for day to day use?"
Presumably this will be a 997, not the current 991? Even so, it is much more fun to drive than a 6 Series. So depends what you want it for. If you want it for performance driving, get the Porsche, even though with the top cut off it is not as sharp as a coupe. If you want a top-down cruiser for the summer that's also relatively civilised on the motorway, get the BMW. I think the BMW will depreciate more heavily.

Should I buy a 2WD Skoda Octavia and fit winter tyres rather than buy the 4WD version?
"I was very interested in your answer to MA of Stroud regarding the merits of a winter tyre-shod Porsche Carrera S rear wheel drive against the 4WD version without winter tyres. As I currently drive a Skoda Octavia 4x4 estate and am thinking of changing to another, would it makes more sense to buy the two-wheel drive version and fit winter tyres, and would the difference be as marked as you say it was with the Carrera? I have seen the Autocar video of two Yetis in the snow and the 4x4 version only wins on an acceleration test, but not climbing snow-covered hills."
A 991 C4S on Pilot Alpin AP4s (with ESP engaged) proved virtually uncrashable in the snow, while a front-drive Peugeot 2008 with 'Grip Control' (which included Goodyear Vector 4 Seasons tyres) was far more capable driving up a 3-in-I snow covered ski slop than a four-wheel drive on summer tyres.

Would you recommend I buy a Mercedes-Benz SLK or a Porsche 911?
"I am looking to buy a fun car within a budget of about £20,000. It will be a second car and will not cover many miles. It needs to be a convertible, with an auto/semi auto box. I have narrowed it down to either a Mercedes-Benz SLK AMG, as I have been very pleased in the past with SLKs, or a Porsche 911 C4S, wide-bodied. The back seats of the 911 would be useful with our small grandchildren. I am not bothered about the soft top as it will be garaged. I have never had a Porsche so have a leaning in that direction, but your views on both cars would be appreciated"
These are wildly different cars. The SLK has quite a lot of power, but fairly unresolved suspension. I find them a bit dangerous to drive quickly. The 911 is pure sportscar, but £20,000 doesn't get you a very good one. For a start, if you want automatic, this will be the old torque converter Tiptronic slushbox. And if you want a convertible 4S it's going to be the older 996. The 3.6 was a lot more reliable than the 3.4, but great care needs to be taken buying one of these and a proper warranty is essential, otherwise you could get hit with £12,000 for an engine rebuild.
