2012 Porsche Panamera Diesel Review

From Germany to Bologna on only one tank of fuel: With a variety in excess of 1,200 kilometer (~746 miles) the new Porsche Panamera Diesel powered is a good bet as a definitely reasonable GT saloon. The long-range cruiser motorcycle with an outstanding turn of rate includes the fantastic features of Porsche's Grandma Turismo family with common diesel features such as excellent gas mileage and oodles of pulling energy. In the process, the new four-door car provides yet another primary example of "Porsche Wise Performance", daemonstrated in each and every progression.

The website features of the new Panamera Diesel powered enable it to take strolling and increases easily in its pace. Typically for a diesel, 550 Newton yards of performing twisting - 50 Nm more than for the Panamera S with V8 website - are used to the crankshaft between 1,750 rpm and 2,750 rpm. Twinned with the highly successful eight-speed Tiptronic S, this energy progression helps the Grand Turismo to achieve in-gear speed from 80 km/h to 120 km/h (~50 mph to 75 mph) in 4.5 seconds, for example.

The three-liter six-cylinder V on the bonnet of the 2012 Porsche Panamera Diesel is the state of the art in diesel technology: Auto Start / Stop, direct injection common rail piezo valve through a pressure of 2000 bars, with a turbocharger variable geometry turbocharger controlled electrically (VGT) and the emission control achieved by the recirculation of exhaust gases controlled oxidation catalyst and particulate filter. This is how high performance, generous torque and low power consumption are accompanied by proper operation, reliability and low emissions. The Panamera Diesel meets Euro 5 limit values ​​and approved accordingly. The V6 operates as efficiently as the only heat is unlikely to be evacuated by the cooling water. Internal temperature of comfort, despite the cold of the heating system is complemented by an auxiliary heating system.

The Porsche Panamera Diesel has an on / off automatically, which automatically shuts off the engine when the vehicle is stopped and the brake pedal is pressed - for example at traffic lights or in traffic jams. If you release the brake, the system restarts the engine. The processes are optimized function so that the restart is very spontaneous. The function saves fuel and reduces CO2 emissions, without the driver having to change their driving habits. The audio communication systems and continue to work even though the engine is off, the air conditioning system ensures that the selected temperature is maintained motor restarts if more power or cooling capacity. The Auto Start / Stop can be activated or deactivated by pressing a button. In some situations, the function is inactive, for example, when the outside temperature is very high on steep slopes or when the battery is low.

As in all Panamera models, recovery of the electrical system also provides additional fuel to the main battery is charged during braking. When the car accelerates, on the other hand, the load current of the alternator is reduced - the combustion engine is not necessary to provide power to both charge the battery.

The base engine for the new Porsche Panamera diesel is composed of a casing with two rows of cylinders at an angle of 90 degrees and the other is cast iron with vermicular graphite. A balance shaft is mounted to improve smooth. The six cylinders have a 83 mm (~ 3.3 inch) bore, the piston is 91.4 (3.6 inches) mm for a total displacement of 2967 cc. The aluminum cylinder heads, each containing two camshafts and four valves per cylinder mounted vertically. The valves are activated by a low-friction rocker arms with hydraulic valve components clearing customs. The rise vertically in the center of the injector is placed directly above the central piston recess. This design ensures a good mixture formation, resulting in low consumption and low emissions.

The six-cylinder engine equipped with fuel via a common rail system, where diesel fuel is at a pressure up to 2000 bar and made available to the nozzle by means of a short rail injector. This offers three important advantages: the injection pressure is almost freely chosen card feature, the high injection pressure ensures optimum mixture formation and the injection sequence with injections of pre-and post primary can be designed to be very flexible.

Fuel is injected into the combustion chambers controlled switch piezo injectors that less than one ten thousandth of a second. The opposite effect is used to control the piezoelectric actuator piezoelectric: when a voltage of 110-148 volts, the piezoelectric actuator extends to 0.03 mm. This effect is applied to the injector needle, which opens the injection tube. Compared to the injection valves with magnetic actuators, piezoelectric technology in the mass movement of the injector needle is reduced by 75 percent.

A variable geometry turbocharger and downstream of cooler air from the combustion air supply. Like the 911 Turbo, the turbo has adjustable blade guide which can be used to modify the characteristics of increased pressure of the turbine. In the revolutions of the motor, adjustable guide blades for high torque and good response by ensuring high-pressure turbine reaches an accumulation and therefore the ability to work with the leaves-guide "closed" and the flow rate mass is low. When the engine speed increases, the guide vanes are permanently open, ensuring fuel consumption as low as possible by reducing the pressure on the exhaust pipe. The guide blades are adjusted by an electric motor, providing a quick guide sheet adjustment and precise engine response and spontaneous.

Sophisticated exhaust system ensures that the current standard of Euro 5 limits are largely met. According to the map of the motor part of the raw gas is back in the combustion process through the recirculation of exhaust gases of the population. The inert gas supply from the maximum combustion temperature is reduced, thus reducing emissions of nitrogen oxides. Colder in the recirculation of exhaust gases ensures a greater reduction of combustion temperature and a greater amount of exhaust gases can be recycled Quan.

Downstream of the turbocharger, the exhaust gases pass on through the oxidation catalyst, diesel particulate filter (DPF) and silent. The extent to which the filter is clogged with soot particles is calculated by connecting two models pre-programmed into the engine control system. One model is calculated from the user's driving profile with the signals of temperature and exhaust gas sensor for oxygen. The pattern of obstruction of others are provided by the flow resistance of the FAP, calculated using the signals from the pressure sensor temperature of the exhaust gas flow meter of exhaust air.

Porsche Panamera Diesel is available exclusively for the eight-speed Porsche automatic Tiptronic S control program was tailor-made for diesel engines: Since a narrow range of speed settings move the access point is completely different from the hybrid the Panamera S, which is the only Grand Tourism is equipped with eight-speed transmission. In practice, the Panamera Diesel change in behavior is substantially similar to that of Gran Turismo with the PDK transmission. Diesel Tiptronic S transmission shift points tailored to your driving style and the Route Profile. Alternatively, as usual, the Porsche, the transmission can be changed manually by pressing the switch by touching the steering wheel or the selector lever. In order to transmit the high torque of the V6 engine with a minimum loss function block converter clutch.

To save fuel, the characteristics of the Tiptronic S decoupling stopped the car in sync with Start / Stop, automatic selection of the neutral position when the brake is activated when the vehicle is stationary, the engine is running and road surface is at.

The proportions of fragrant classic forms Porsche Design, Porsche Panamera Diesel is distinguished for its class of vehicle. The new model has standard halogen headlights, Bi-Xenon system is available as an option to have cornering lights and Porsche Dynamic Light System (PDL). Side window surrounds are matte black. The new diesel is equipped with two oval tailpipes in brushed aluminum, one of the backward cone, which emphasizes the dynamic profile Panamera rear. Porsche Panamera diesel engine operates in 18-inch alloy wheels as standard with five-spoke design, which offers a glimpse of the calipers black.
