Anhangerkupplung (trailer coupling)
Four–wheel drive in the past has been used to improve vehicles' off–
road capabilities and/or their mobility in winter. Porsche, however, is
a leader in exploiting and refining this principle to obtain optimum
power distribution and traction under all conditions, at all times—
hence the term "all–wheel drive."
Automatic Transmission Fluid
Abbreviation for "brake horsepower," or horsepower as measured with
the engine on a dynamometer, rather than driving the car. There are
two popular standards for the measurement of horsepower—the
American SAE net and the European DIN. DIN may be converted to
SAE by dividing the DIN bhp by 1.014. Although certain European
models may have higher bhp, it may be the same as the U.S. version—
just measured differently.
Cold Air Intake
Controller Area Network. A wired network used on cars.
Compact Disk Changer
Check Engine Light (same as MIL)
Dynamic Driving Differential
A mechanical limited slip differential
that exhibits differing lock factors under acceleration and deceleration.
Direct Fuel Injection - The direct fuel injection (DFI) used in the new 911 flat-six engines is based on homogeneous direct injection. In this process, electro-mechanically controlled fuel injectors inject the fuel directly into the combustion chamber at a pressure of approx. 580 psi to 1740 psi (40 to 120 bar) and with millisecond accuracy as required by the respective driving state. The mixture of air and fuel is distributed as evenly as possible in the combustion chamber, thereby allowing optimal combustion.
The spray cone angle and injection-jet orientation have been optimized to achieve optimum homogenization in the entire operating range. Within the injector, the fuel jet is twisted (rotated around the longitudinal axis). This rotation forms a conical
cloud of fuel. The fine atomization produced in this way allows faster evaporation of the fuel.
The heat energy required to evaporate the fuel is absorbed from the combustion air, thereby cooling the air. This reduces the cylinder charge volume and additional air is drawn in through the open intake valve, which in turn improves cylinder charging.
Lowering the temperature reduces susceptibility to knocking and additionally allows the compression ratio to be increased. The higher compression ratio in turn increases the engine efficiency. This reduces fuel consumption, particularly in the partial-load range.

Low Emission Vehicle
Left Hand Drive
A type of differential which limits the degree of variation in wheel speed between the two driven wheels, thus reducing wheel spin under conditions of poor traction. The limited–slip differential begins to restrict the power supplied to a spinning wheel by a predetermined amount, reducing the speed of rotation of the spinning wheel to that of the wheel which still has sufficient grip. The result: traction is not interrupted appreciably, allowing the car to keep moving.
Porsche's trade name for gas discharge headlamps which employ an electrical arc within a bulb filled with xenon gas. Gas discharge headlamps cast a light that more closely matches the color balance of daylight, thus improving color recognition at night.

Porsche Dynamic Chassis Control
Pre–Delivery Inspection Center - The Porsche Cars N.A. facilities in Charleston, South Carolina where new Porsches are "logged in" to the U.S. prior to being trucked to the dealer network. Each new Porsche receives a 94–point final quality check, a dynamometer test and brake run–in prior to being detailed and loaded onto special covered transporters for the last leg of their journey from the factory to their new owners.
Transmission Revolutionary new twin–electric clutch transmission under development at Porsche. The Porsche PDK gearbox allows the driver to concentrate more totally on steering and throttle actions, moving the gear selector from gear to gear without depressing a clutch.
The Porsche Doppelkupplung transmission (PDK) is both a manual and automatic transmission. The special feature of PDK is that two gears can always be engaged one gear is engaged while driving and the next potential gear is already pre-selected.
When shifting, the clutch on the active gear opens while the other clutch engages the pre-selected gear at the same time. This happens under load and so quickly that the power flow is permanently available.
Due to its fast gear changes without any significant power flow interruption, the 7-speed Doppelkupplung transmission offers much better driving dynamics than a conventional manual transmission, with the convenience of an automatic transmission.

Porsche Hill Control
The hill-holder function on Tiptronic S (or Porsche Drive-Off Assistant on vehicles with manual transmission) allows the driver to stop on a hill and drive off again without having to operate the brakes. It also enables a steady slow descent down steep slopes or icy mountain roads at speeds of up to 20 km/h (12.5 mph) using engine braking. This is provided by the engine drag-torque control (EDTC) system, which prevents wheel lock-up on overrun or following downshifts on low-grip surfaces. Selective braking is applied to individual wheels resulting in a considerable increase in steering precision.

Porsche Side Impact Protection System
Porsche's Variable Limited Slip Differential
This sophisticated torque distribution technology provides improved traction and handling stability when moving off from a standing start, driving fast and braking on curving roads, and driving on roads with poor traction. The system's control unit modulates hydraulic pressure in response to wheel slip, as recognized by the anti–lock brake system's wheel sensors, and cornering force as "read" by a special sensor. Locking action is automatically varied from 0 to 100%, depending on dynamic operating requirements.

Porsche Stability Management
A highly sophisticated dynamic control technology designed to stabilize the car in an extreme situation by intervening in the engine management and brake systems. Wheel, brake, engine and steering data are compared to a skid sensor's reading of the vehicle's slip angle and rate. To ensure the car maintains an ideal cornering line, brake pressure is applied to individual wheels, engine output is regulated and, with the Tiptronic S transmission, even shift parameters are adjusted.
Porsche System Tester 2
Porsche Traction Management (on Cayenne).
The heart of PTM is a permanent four-wheel-drive system with a lockable center differential. This electronically controlled unit distributes torque to the front and rear axles using a standard torque split of 38% to the front, and 62% to the rear. In difficult terrain, the differential can be locked via the PTM control.
PTM also incorporates a two-speed transfer gearbox (with low-range gearing for off-road use), an automatic brake differential (ABD) to optimise traction, as well as anti-slip regulation (ASR) for greater stability under acceleration.

Thermodynamically Optimized Porsche engine
The term "TOP" has been applied to the inline four–cylinder engine used in the Porsche 968 model because of its unusually high compression ratio for a production engine, and its special combustion chamber pattern. The engine has a maintenance–free valve gear, DME engine management with electronic control of fuel injection and ignition, and is ideally equipped for a responsive flow of power, good starting and warmup, high efficiency at minimum possible fuel consumption and low exhaust emissions.
