The A-pillar, the front roof pillars of a car, between the bonnet and the front door.
See also: B-pillar, C-pillar and D-pillar.
The drive shaft transmits the power of the motor from on the differential to the driven wheels.
The drivetrain is the collection of all the components that ensure the ability of the vehicle is converted into propulsion. Successively they are: the engine, clutch, gearbox, drive shaft, differential, drive shafts and the driven wheels.
A synonym for powertrain, drive train.
When we have the car in terms of the point of application, we mean the point at which the clutch grabs ?? ??. If you let the clutch, the car at some point starts to roll: That point is called the point of action. From there, the operator starts the car to actually put into motion.
Active Body Control.
ABC detects and corrects diving and rolling movements of the body and the vehicle always remains flat on the pavement.
Anti blocking system.
ABS works with a number of sensors on the wheels, check the wheel when braking tends to slip. If that happens, the braking force is reduced electronically up to the point at which the wheel is no longer slipping. A car equipped with ABS remains under braking at all times to steer because the tires roll. This is in contrast to a car without ABS, which can go sliding.
See also: BAS
Antilock brake system plus.
ABS + is an evolution of ABS. ABS + takes into account the surface on which you are traveling. The idea that you stopped earlier with rolling wheels with locking wheel does not always hold true. ABS + takes this into account and adjusts the braking to the surface.
Adaptive Cruise Control
ACC is an addition to the regular cruise control. Besides the constant maintenance of the set speed ACC also takes into account the distance to the vehicle ahead. ACC ensures that the set distance to the vehicle in front is always maintained. If the brakes are applied for you, ACC also slows the car to keep the distance. Does your pastor again than ACC accelerates the car back to the set speed and distance.
Second meaning ACC: ACC is also used for "Automatic Climate Control"
Active Cornering Enhancement
ACE is a system by means of sensors and hydraulic adjustable stabilizer bars of the car body roll can affect artificially. This allows the car additional stiffness and law are held during fast cornering, and can be generated in bad weather or terrain work extra role.
The distance that can make a car on a full tank of fuel.
Active head restraints are designed to injury in a rear collision as much as possible. Sensors detect when the car is struck from behind, after which the headrest is raised a few centimeters, so that the head is received at an earlier stage, and thus reduces the risk of a whiplash injury.
In recent years, the pedestrian collision safety has become an important issue. Cars equipped with an active bonnet having a plurality of sensors in the nose to detect a collision. Then, the engine cover on the window side is lifted a few centimeters and placed in a corner, through which the pedestrian makes a softer landing, which reduces the risk of injury.
Under active safety means services which contribute to safety when driving. This therefore help to prevent an accident. Examples of active safety, ABS, ESP and traction control.

Adaptive cornering headlights lighting is working with the steering movements of the driver. When the driver steers into a bend, the light it turns to immediately turn the light on the bend. Thus, the driver a better view of the road and potential hazards can be spotted sooner.
In aerodynamics, the influence of air is provided for moving on a vehicle. In the case of car ?? s is that wind. Among aerodynamics also includes the shape of the car itself and how it cuts through the air ?? ??. A commonly used term that gives an indication of the aerodynamics of a car is the drag coefficient. The lower the number of this value, the lower the drag of the car. Good aerodynamics is essential. After all, the lower the resistance, the less power the car needs to move. Overall, improved aerodynamics means lower consumption and higher performance.
Another important component of aerodynamics is the downward pressure. Especially in racing, this is a crucial component. Downforce or downward pressure, the airflow that presses the car on the asphalt. The more downforce, the grip has a car in principle. Down Force is, inter alia, obtained by the use of spoilers. Formula one car ?? s are a good example of aerodynamic inventions: they have an aerodynamic design that closes topcompromissen: they are designed to minimize encounter resistance, but at the same time the air flow must be the car as much as possible touching the asphalt, so that it can take corners fast.
A fun fact: the most aerodynamic shape is the water drop. Water is fully moldable and when it falls, it automatically takes the teardrop shape, because the resistance of the water is so. The water is formed by the air resistance so such a way that it can fall the fastest.

Adaptive Front Lighting
Adaptive Front Lighting follows the steering movements of the car. For example, when the car turns left, AFL calculates by means of the steering angle how the curve runs and turns the headlights so that the portion to which the car moves is illuminated increasing. Another widely used synonym for AFL is AFS.
The noise generated by the tires when driving. When there are many rolling noise penetrates the interior one will experience this as disturbing. In a car engine produces little noise, rolling noise falls frequently.
Adaptive Front Light System.
AFS adjusts the beam of the car to the circumstances so that the road and surroundings at all times is optimally illuminated. AFS is often combined with Adaptive Headlights, the light rotates with the direction of the car in order to better illuminate the bend.

You will undoubtedly have a look at your tires look and have asked yourself what does that code? This "code" is the tire designation and this tells you everything about your band. On the basis of the example below, we will explain this out.
205/55 VR 17
205: the width of the tire in inflated condition in millimeters.
55: the roundness of the cheek. The number is a percentage of the width of the band. In this case, the height of the cheek is thus 55% of the width. The higher this number, the "rounder" the cheek end, the lower the platter. Sport Tyres are always a lower value than normal tires, because the flatter the cheek, the more tread is in contact with the asphalt.
Q: This letter indicates what the speed limit is allowed to drive with this tire. The following letters are used: Y 100 km / h, K: 110 km / h L: 120 km / h, M: 130 km / h N: 140 km / h, P: 150 km / h, Q: 160 km / h, R: 170 km / h S 180 km / h, T: 190 km / h H 210 km / h, V: 240 km / h W 270 km / h, Y: 300 km / h ZR:> 240 km / h.
R: This indicates the type of tire. R stands for radial tire. Is there a "D" this means diagonal band.
17: This number represents the rim size in inches.
Sometimes the code is slightly longer and classified in other activities such as: 205/55 R 17 88 V
The "V" is now at the back but also means the same. Added in this example, is "88". This number indicates the load index per tire. The larger this number is, the higher the bearing capacity.
An electronic system that monitors the tire pressure. If the voltage is higher or lower than the standard value, the driver is alerted.
BAS helps the driver to come to a stop as quickly as possible during emergency braking, optimizing the braking pressure. Is braked sharply, then BAS recognizes this as emergency braking and automatically boost the maximum brake pressure.
Brake Assist PLUS
BAS helps the driver to come to a stop as quickly as possible. BAS PLUS goes one step further. The term BAS PLUS comes from Mercedes-Benz which includes the S-Class and CL-Class provide them. BAS PLUS is working with a radar system that detects vehicles from the car. On the basis of the measurement data performs calculations by BAS PLUS and determines the right type remmanouvre in order to come to a halt as quickly as possible. Because the system "knows" how the driver to go slow, it already carries the brake pressure to the appropriate level and the car is all ready to assist the driver in his stop.

By Brake Energy Regeneration braking energy is used to recharge the battery. Normally, the battery will be charged by the motor, which is free of power output and leads to a higher energy consumption. By Brake Energy Regeneration, the engine will not charge the battery, but uses the full power of the engine for propulsion. In place of the motor which charges the battery, kinetic energy of the brakes is converted into electrical energy to load with the battery. For example, the battery every time the brakes are applied is loaded. Brake Energy Regeneration is efficient and helps reduce fuel consumption and emissions.

The choke is a valve that regulates the amount of air in the mixture of the carburetor. When starting with a cold engine, a portion of the fuel to deposit on the cold piston wall, it needs more fuel. By closing the valve, the mixture is automatically richer, making the engine easier to start. Old car ?? s have a manual choke, which was later replaced by an automatic choke. Contemporary car ?? s see for injection do not choke anymore.
Incidentally, it was necessary to start a car with too much choke Throttle up. Then the gas mixture was too rich and could drown the car. This means that the spark plug is wet and no spark gives more.
"Close Ratio" means that the ratios are close to each other. A close ratio gear box has a relatively long first gear, while the rest of the gears are closer together. This results in less rpm decay when changing gears. This is ideal for car ?? s with a steep power curve, which means they deliver their maximum power in only a small part of the rev range. By mounting a close ratio gearbox, the rider can keep the revs easily in the ideal range. Close ratio transmissions are less suitable for all-round car ?? s for the open road.

Tuning consists of two facets: optical tuning and technical tuning. Optical tuning is to say, the modification of the appearance of the car. Technical tuning is to improve the performance of the car by making adjustments to components. Both forms of tuning usually go hand in hand.
A turbocharger consists of two blade wheels which are fixedly connected to each other with a shaft, one in the inlet channel and one in the outlet channel. The engine compresses at high speed the exhaust gases through the outlet and thus the blade wheel in the exhaust from turning and thus also the blade wheel in the inlet. This pressurizes thereby with positive air pressure in the inlet channel: more air in the cylinders is the result, so there is more fuel can be injected, and which provides more power. A compressor has a similar effect, however, which is driven mechanically, while a turbocharger is driven by the exhaust gases. Both have their advantages and disadvantages. A compressor is generally faster in the lesson, because it does not need to get under way, thanks to the mechanical drive. On the other hand costs drive the compressor in itself a little power, making the net proceeds of a turbocharger in the base which is higher.
A two-stroke engine is a piston engine that supplies power for each downward movement of the pistons in the cylinders. This is in contrast to a four-stroke engine in which the pistons providing power at every second downward movement. The operation of a two-stroke engine based on the same principle as the four-stroke engine, but the process is different. Instead of four 'strokes', the two-stroke engine has only two "hits" in which it does the same as the four-stroke engine. In a four-stroke engine is a mixture of petrol and air is introduced into the cylinder. The mixture is compressed by the piston, which for this purpose again moves back into the cylinder. Then there is an inflammation that creates an explosion, which pushes the piston. Finally, the exhaust gases are driven out by the plunger that comes to the inside again. The two-stroke engine has only a power stroke and a compression stroke. The two-stroke engine has no valves, but an outlet port. The inflow of the fresh air is effected by means of transfer ports at the bottom of the cylinder liner which are in communication with the carburetor. At the moment that the piston is at the top of the cylinder and it moves downward, will open the exhaust port at a given time, and will be open to the transfer ports by the piston itself. And more gasoline is sucked in again.
Twin scroll technique relates to the operation of a turbocharged engine. Twin scroll technique is to say that the turbocharger has a small and a large paddle wheel. In the initial phase, does the small impeller, this ensures that the turbo speed can be quickly and can respond quickly. When he turns and must be delivered more power once, the great paddle wheel takes over. A common synonym for a twin scroll turbocharger is a dual stage turbo.
Twin turbo is to say that there are two turbo ?? s are present in the motor.

A Lexus-derived term for a system in which various active safety systems such as ABS, traction control and stability control are integrated.
A four-stroke engine, as found today in all passenger ?? s find, has four processes to complete one stroke. 1: the suction of fresh air and injecting the fuel 2: compressing the mixture, 3: the burning of the mixture, 4: the outlets of the combustion residues via the valves.
Variable Valve Timing and Lift Electronic System.
Honda used term for variable valve timing.
A W-motor is a relatively rare construction, wherein the cylinder rows in a sectional view along a W-shape. See a W engine as an interconnected V-engines. Two V ??, and, after all, make a W. Often, a W-motor is also coupled to a V-engine to each other, such as by Volkswagen and Audi which supply the Phaeton and A8 with W12.
The wheelbase is the distance between the center of the front wheel and the center of the rear wheel. A longer wheelbase usually creates more space in the interior. Much more expensive models like the Audi A8 and BMW 7-Series known versions with an extended wheelbase, which won space benefits the rear passengers.
Windowbags airbags are incorporated in the mullions of the car. They are inflated on impact and form a protection between the head of the occupant and the window.
The sound produced when the wind blows along the body of the car. Cars with an inferior aerodynamics are more likely to produce a lot of wind noise. Wind noise can be disturbing and especially on vehicles with a quiet engine can wind noise dominate in the interior.
A wind tunnel is a large hall in which air flows can be generated in order to examine the influence of an air flow on the carriage of a car. By mixing with a powder of wind, there is a visible stream. So one can see how the air moves over the car. On the basis of these adjustments can be made in order to improve the aerodynamics of the car.

Water Repellent Glass
WRG is water repellent glass. It is often used in mirrors, but increasingly also on windows. Volvo is experimenting with WRG on the windshield: this wipers would be superfluous. However, this glass is not to get into production.
Designation BMW for their four-wheel drive system. The technique works like this: a transfer case in the powertrain is controlled by intelligent electronics and a multi-plate clutch distributes drive power variably and continuously between the front and rear axle. If more torque to be sent to the front axle, then an electric motor rotates a round disc in the transfer case. Via a transmission is compressed, the multi-plate clutch, which is transmitted via a chain to the desired drive torque, within a fraction of a second on the front axle. Thanks to the variable distribution of drive power to the self-steering behavior is already positively affected at baseline. The car tends to understeer, xDrive reduces the drive torque than before and thus increasing controllability, respectively agility. In extreme cases there may even be virtually only rear wheel drive. At upset xDrive sends the drive torque to the front wheels, and thus contributes to the stabilization of the car.
Xenon lighting is often found standard on more expensive car ?? s. Instead of a glow plug causes an electric arc to the light. Xenon technique creates a twice as intense beam of light as a halogen lamp, which allows for a better and more visibility. Xenon lamps are more expensive, but have a longer life and lower energy consumption than halogen bulbs. Xenon lamps are recognizable by the bluish light. Some people experience the bright, blue beam as hindering.
A sore emission vehicle is a vehicle that produces no harmful emissions, such as gasoline and diesel vehicles to do. A zero emission vehicles are all fully electrical or hydrogen-powered cars.
Side airbags are airbags that are mounted in the side of the chair. In an impact they are inflated in order to protect the body from the side.
The center of gravity is an important term in the car world. The center of gravity of the car is the point around which all the mass is evenly distributed. This is thus not the same as the center point. Automakers seek the center of gravity as far as possible to get down. The closer the center of gravity of the vehicle when the road surface is, the better the handling and the lower the body movement of the body. Usually has a higher car a higher center of gravity, therefore, an SUV more tendency to hang ?? ?? at the bend than a sports coupe.
