Postche has recently launched four new aspects of his mythical Porsche Carrera: 911 Carrerá 4 Coupé, 911 Carrera 4s Coupé, 911 Carrera 4 Cabriolet and 911 Carrera 4S Cabriolet.
911 Carrera 4 Coupé
The new 911 Carrera 4 has a greater width of the body (44 mm more in the rear fins) and rear tires with a width of 295 mm.
One of its intrinsic strengths is, naturally, its propulsion: with the 3.4 -liter and 257 kW (350 hp) hexacylinylindric engine to a 7,400 rpm regime, the new 911 Carrera 4 accelerates in just 4.9 seconds from 0 to 100 km/h. With a maximum speed of 285 km/h.
Perhaps the strongest strong point of this model is that CO2 consumption and emissions have decreased up to 15% in relation to the previous model, thanks to the resistance of the displacement.
911 Carrera 4S Coupé
in a sports car that offers great adhesion to the ground. With a wide body in 44 mm, a wider track width and rear wheels of 305 mm width.
It has a 3.8 -liter and 294 kW (400 hp) boxer engine to a 7,400 rpm regime, which with optional PDK change reaches 100 km/h in just 4.3 seconds. The progression does not end until reaching the maximum speed of 297 km/h. The fuel consumption and CO2 emissions of the new 911 Carrera 4S are up to 13% below those of its predecessor.
911 Carrera 4 Cabriolet
The new 911 Carrera 4 Cabriolet is propelled by a 3.4 -liter boxer engine with 257 kW (350 hp) that offers high performance. To accelerate from 0 to 100 km/h in 5.1 seconds to a 7,400 rpm regime. And with a maximum speed of 282 km/h.
Another important more benefit is that, thanks to the resolved engine, consumption and CO2 emissions, up to 16% below the values of the previous model.
The new development hood of 911 Carrera 4 Cabriolet adapts to the weather and mood conditions of its driver. In thirteen seconds at any speed that does not exceed 50 km/h.
911 Carrera 4S Cabriolet
The 911 Carrera 4S Cabriolet has a 3.8 -liter boxer engine, with direct gasoline injection (Direct Fuel Injection - DFI). It also has a power of 294 kW (400 hp) to a 7,400 rpm regime. Accelerates from 0 to 100 km/h in 4.7 seconds and its maximum speed is 296 km/h.
Like the previous models, fuel consumption and CO2 emissions of the new 911 Carrera 4S Cabriolet are also up to 14% below those of its predecessor.
One of the changes introduced by 911 Carrera 4S Cabriolet is its fabric hood with magnesium elements: light, robust and especially rigid. It opens in just thirteen seconds at speeds of up to 50 km/h.
Design: The identity of the Porsche 911
The general impression that gives a Porsche 911 in sight is that it is a deep, wide and plane car, general features that have maintained since 1963. Notwithstanding the last 911 Carrera introduce changes with respect to the previous models.
The elongated battle in 100 mm improves driving stability and curves, in addition to offering 25 mm more of the pilot and co -pilot's legs. The blasting ones are short and 911 have a compact and agile appearance. A more sporty global impression that is also confirmed with a lower height compared to the previous model, as well as with the widening of the track width.
In the rear, the angles dominate, the product of a clear line of lines and the narrow rear lights of light diodes, which underline horizontality. The illuminated strip of rear pilots of total traction models further intensifies that impression. Adaptive brake lights also have luminous diodes technology and emit a pulsatile intensity light in case of emergency braking.
On the front, total traction models include cooling air intakes in the front fairing. The bi-xenon headlights are standardly supposed, with their oval framework, a classical reminiscence.

Chassis
911 Carrera 4 and 911 Carrera 4S, optionally have the first and standard the second, of the Porsche Torque Vectoring (PTV) or the Porsche Torque Vectoring Plus (PTV Plus). Both are a system to increase vehicle stability through controlled intervention on rear wheel brakes and a transverse rear axle block. In the PTV it is regulated mechanically, in the PTV plus electronically.
More specifically, in a dynamic driving style, the rear wheel on the inside of the curve is slightly braking with the direction of the direction. In this way, the rear wheel on the outer side of the curve has greater motor force, which allows it to provide an additional rotation impulse in the direction towards which the turn occurs. The result is a more direct and dynamic turn in curves.
At medium and low speeds, the PTV and the PTV plus significantly increase agility and turning precision. At high speeds and when it is accelerating from the curves, the transverse blocking of the rear axle also provides greater circulation stability.
On the other hand, the Porsche Dynamic Chassis Control (PDCC) is an optional system for active lateral stabilization in 911 Carrera 4s. This minimizes the lateral inclination of the vehicle in the curve sections. It also minimizes lateral balancing on undulating firm. This is carried out by stabilization hydraulic actuators, that is, cylinders to optimize the fall. Thus, in each of the wheels, forces develop, depending on the flying of the steering wheel and the transverse acceleration, which counteract the lateral inclination of the vehicle. What does this bring? The vehicle sits much better on the road and the driver can travel the curve more quickly and relaxed. The PDCC marks new guidelines in terms of benefits, driving comfort and fun at the wheel.
Total traction
vehicles with total traction include the Porsche Traction Management (PTM). A series of sensors controls, among other things, four -wheel revolutions, that is, longitudinal acceleration. In this way, total traction can react at all times to the different circulation circumstances and regulate the distribution of traction forces between the front and rear axes.
The PTM is composed of an active total traction with a multidiscut of electronic regulation managed by characteristic fields, the automatic brake differential (ABD) and the traction control (ASR).
The completely variable multidiscus clutch of electronic management regulates the distribution of the driving force between the permanent traction rear axle and the front axle. In addition, the ASR prevents the wheels from skidding timely adapting the engine power.
In this way the PTM, in combination with the Porsche Stability Management (PSM), ensures in any circumstance of circulation the proper tensile distribution for an excellent progression: both in long straight and in closed curves or on firm with different friction values.
Comfort
The materials that include the new ones are Porsche 911 Carrera 4 are of high quality and very sports. The steering wheel ring, the doors and the armrests are upholstered in sewer leather, the Coupé models roof gallery is up to it.
The CDR audio system with 7 -inch color touch screen and the Sound Package Plus sound package are included as standard and offer an excellent sound with a total power of 235 watts. The (PCM), optionally available, with 7 -inch and high resolution color touch screen also has a navigation module, which acts as a central control unit of audio, navigation and communication functions. On an option, the Bose® surround sound system can also be available with a power of 445 watts or with the High-End envelope of Burmester®, one of High-End's most prestigious suppliers throughout the world, with 821 watts of total power and an unprecedented sound.
