2012 Porsche 911 (991): official details, photos, specs and price

Article by Christian A., on August 23, 2011

After few leaked photos, Porsche has finally unveiled the all-new 911 (991) and announced that the vehicle will be unveiled next month at the 2011 Frankfurt Motor Show. As expected, the 2011 Porsche 911 (or the so-called 991) is with 45 kilograms lighter than the current model and has a longer wheelbase (with 100 millimetre or 3.9 inches).

The first model revealed by Porsche is the 911 Carrera, which is powered by the 3.4-litre boxer engine delivering 350 hp (~ 257 kW) and capable to offer a fuel consumption of just 8.2 litres per 100 kilometres (~ 34 mpg imp.) and 194 g/km CO2, with 1.6 l/100 km (~ 6 mpg imp.) less than its predecessor.

Still, the 911 Carrera can sprint from 0 to 100 km/h (62 mph) in just 4.6 seconds when paired with the PDK, and in just 4.4 seconds when using the Sport Plus. The 2011 Porsche 911 Carrera S is powered by a 3.8-litre boxer engine delivering 400 hp (~ 294 kW) and a fuel consumption of 8.7 l/100 km (~ 32 mpg imp.), when paired with the PDK.

This means a 14% drop or 1.5 l/100 km (~ 5 mpg imp.). The 911 Carrera S with PDK can accelerate from 0 to 100 km/h (62 mph) in just in 4.3 seconds and in just 4.1 seconds when using the optional Sport Chrono package.

In addition to the longer wheelbase, the 2011 Porsche 911 offers greater agility, precision and driving stability are based, among other things, on the wider front track, the new rear axle and new electro-mechanical power steering. For the first time, the Porsche Dynamic Chassis Control (PDCC) active roll stabilisation system is available for the 911 Carrera S.

For those who don’t know, this system reduces the system reduces lateral inclination when cornering and keeps the tyres in the optimal position relative to the road surface. This means that the maximum cornering speeds are increased. Regarding the prices, the 2012 Porsche 911 Carrera is available for 88,038 euro (including 19 per cent VAT), while for the 2012 Carrera S you will have to pay 102,436 euro (including 19 per cent VAT).

With the latest Porsche 911 Carrera S having a new design for its exterior, the designers at Porsche made sure that the interior would complement this using the Porsche Carrera GT’s architecture as a basis.

The cockpit for instance, has a motorsport feel to it considering that the driver is closely integrated to it even more. This is the result of having the gear selector, or gear lever, mounted higher and placed nearer to its steering wheel. It helps that the center console now rises to its front. On this same console, the vital settings and function buttons needed to run the 911 Carrera are housed in a logical grouping. The dashboard meanwhile has been redesigned and in the middle of which is the 7-inch touchscreen that the driver can use to manage various functions.

Even with these changes, the design team made sure that it continues to have the classic Porsche feel to it like the ignition lock being located on the left of the steering wheel. Another example is the five round instruments and the rev counter placed in the center. In the interior as well are the seats for the driver and the passenger in the front having electric four-way adjustment. Offered as options are the 14-way adjustment sports seat and an 18-way adjustment version.

What makes this new 911 Carrera S unique is that it will mark the introduction of the Porsche Torque Vectoring or PVT. Fitted as standard, it allows for tracking stability and enhanced tracking in addition to having lower sensitivity for load changes. When combined with the manual 7-speed transmission, it makes up a mechanical differential lock for the rear and the variable torque distribution to its rear axle. For models that have the Doppelkupplungsgetriebe, or PDK, they will be equipped with the PTV Plus.

This feature has a fully variable differential lock in the rear which is electronically controlled. Be it the PTV or PTV Plus, by having braking interventions on the rear wheel’s inside, steering precision and agility are improved. These two features are offered for the 911 Carrera as an option.

The all-new Porsche 911 (991)

The new generation Porsche 911 Carrera is emerging from one of the biggest development steps in the long history of this classic sports car. Almost 90 per cent of all components have been redesigned or redeveloped. With its all-new lightweight body, further drivetrain efficiencies and new suspension systems, the Coupé offers the driver improved Porsche Intelligent Performance. This manifests itself in yet further enhanced driving dynamics, up to 16 per cent lower fuel consumption and emissions combined with even greater everyday practicality.

The Porsche 911 Carrera's design and proportions have developed in step with the technology. One of the most pronounced points of differentiation is the 100 millimetre (3.94 inch) longer wheelbase.The body on the other hand is only 56 millimetres (2.20 inch) longer overall lengthwise, the overhangs being shortened by 32 millimetres (1.26 inch) at the front and twelve millimetres (0.47 inch) at the rear. The Carrera's roof line is around seven millimetres lower than that of its predecessor and around six millimetres for the Carrera S. The maximum headroom remains virtually unchanged. For Coupés with a sunroof, which for the first time is of the electric slide/tilt type, headroom has even increased by 15 millimetres. With an overall length of just under 4.5 metres (176.81 inch) and a maximum width of approximately 1.8 metres (71.18 inch) the 911 Carrera remains the most compact sports car in its class.

The Porsche 911 Carrera's stylistic evolution is apparent from every angle. Viewed from the side, new styling, larger alloy wheels and the more convex windscreen contribute to the even jauntier, more coupé-like character. Typical of the revised, wider front end are the new headlights and larger side air intakes. The wider, variably extending rear spoiler emphasises the new 911 Carrera models' greater power output. Together with other aerodynamic optimisations, it also ensures significantly lower lift while retaining an equally good cd value. Redesigned, narrower LED technology rear lights complete the rear profile.

The Porsche 911 Carrera sets new standards in Porsche Intelligent Performance. The innovative aluminium-steel lightweight body, combined with a raft of new components and functions, benefits efficiency and driving dynamics in equal measure.

The new 911 Carrera is the first passenger car in the world to feature a seven-speed manual transmission as standard. It is based on the module of the optional seven-speed Doppelkupplungsgetriebe (PDK). The close ratio of the first six gears affords the driver outstanding acceleration capability, with the seventh gear's quasi overdrive attributes offering further scope for fuel economy.

The Porsche 911 Carrera is the first sports car that Porsche has equipped with an auto start/stop function. The system can save up to 0.6 litres per 100 kilometres based on the New European Driving Cycle (NEDC). The auto stop/start function is married with both the PDK and manual transmission as standard. The joint thermal management system for engine and transmission and on-board electrical system recuperation reduce the new 911 generation's fuel consumption by a further 0.35 l/100 km. As the new cooling design dispenses with ventilation openings in the underbody, it also affords aerodynamic advantages, which are of benefit to performance.

The "sailing" function, making its very first appearance in a sports car with the optional PDK transmission, can save up to one litre of fuel for every 100 kilometres in everyday driving. If the driver takes his foot off the accelerator, depending on the driving situation, the engine is disengaged from the transmission; the 911 Carrera continues on its way with the engine idling. Especially at higher speeds, this function taps additional potential fuel economies.

In the Porsche 911 Carrera, optimised fuel consumption is complemented by Porsche-style downsizing: The 3.4-litre engine delivers more power from a smaller displacement than its predecessor with a displacement of 3.6 litres. That means the Porsche 911 Carrera with PDK is the first Porsche sports car to make it below the 200 g/km CO2 emissions threshold.

With its completely revamped suspension featuring numerous redeveloped components, the Porsche 911 Carrera raises the driving dynamics bar yet another notch. The longer wheelbase alone, combined with the wider track width at the front, generates an entirely different geometry with more sure-footed tracking and roll stability at high longitudinal and cornering speeds.

With the new electro-mechanical power steering, the Porsche engineers managed to develop a system that combines Porsche's trademark precision and feedback with superior consumption and comfort for the very first time. As the system only requires power when steering, the electro-mechanical system saves at least 0.1 litres per 100 kilometres.

The new active Porsche Dynamic Chassis Control (PDCC), available for the Carrera S as an optional extra, expands the lateral dynamics boundaries yet again by a sizeable margin. PDCC is an active roll compensation system that detects the very instant the vehicle begins to roll when cornering, eliminating it almost entirely. The system makes for greater agility in every speed regime, improved cornering and stable load change behaviour. PDCC therefore represents a new highlight in terms of driving dynamics.

Making its debut in the Porsche 911 Carrera S, Porsche Torque Vectoring (PTV), featured as standard, ensures even better tracking and tracking stability, together with reduced sensitivity to load changes. Together with a seven-speed manual transmission, this system comprises a mechanical rear differential lock and variable torque distribution to the rear axle. In vehicles fitted with the Doppelkupplungsgetriebe (PDK), the even higher-performance PTV Plus comes with the electronically controlled, fully variable, rear differential lock. PTV or PTV Plus further improves agility and steering precision by means of selective braking interventions applied to the inside rear wheel. PTV and PTV Plus are also available for the 911 Carrera as an optional extra.

To complement the Porsche 911 Carrera's new exterior, the Porsche designers created an interior, the architecture of which takes its cue from the Porsche Carrera GT. The driver is now even more closely integrated with the cockpit thanks to the centre console rising up to the front with the high-mounted gear lever or gear selector located especially close to the steering wheel in typical motorsport fashion. The most important function and settings buttons for operating the vehicle are grouped in logical clusters on the centre console. Centrally located in the completely redeveloped dashboard, a larger seven-inch touch screen is used to control a rich array of functions. Naturally, the classic, established Porsche touches, such as the five round instruments with the centrally located rev counter and the ignition lock to the left of the steering wheel are also to be found in the new model. Also, both driver and front passenger are seated on newly developed sports seats with electric four-way adjustment. Additional sports seat versions with 14 and 18-way adjustment are also available as an option.
