Anti-lock Brake System (ABS) in a Car
The anti-lock brakes use four wheel-speed sensors to monitor the speed at which each wheel is turning. This data is shared with the vehicle's powertrain control module (PCM) computer. If the PCM detects that one of the wheels is about to lock-up during braking, it takes control and avoids locking, therefore providing the driver with the maximum available braking capacity of the car and also allowing the driver to maintain steering control.

Benefit

An Anti-lock Braking System (ABS) prevents skidding of the car and helps the driver to maintain control when brakes are applied strongly and suddenly.
This system monitors engine noise within the passenger cabin and counteracts the noise inherently associated with its Variable Cylinder Management to effectively provide an ultra-quiet interior.

Benefit

A car cabin with Active Noise Control (ANC) is very quiet and ensures a peaceful and comfortable ride.
AFS provides electronically controlled superposition of an angle to the steering wheel angle. This provides for a continuous adjustment of the steering characteristics like steering comfort, effort and steering dynamics, depending upon the driving situation.

Benefit

With an Active Front Steering system enables the driver to put in less effort to steer a car. Parking the car becomes easy too as the number of turns of the steering wheel required is significantly reduced.
It is an electronically controlled air suspension system that exists at all four wheels. Adaptive air suspension adjusts the dampers such that the dampers can help the system to adapt to any road condition. It also adjusts the shock absorbers, depending on the car speed, for precise handling and a high-level of ride comfort.

Benefit

The electronically controlled air suspension gives a high level of ride comfort and ensures a sporty drive under all road conditions as the driver can customise the suspension settings as required.
A, B, C, D Pillars in a Car
A-pillars: A-pillars are the posts between the windshield and the front side windows.

B-pillars: B-pillars are the posts between the first door and the second door.

C-pillars: C-pillars are the posts after the second door of the car.

D-pillars: D-pillars are the vertical or diagonal posts located at the extreme rear of the car. Generally found in station wagons and even a few sedans.

Benefit

The pillars in a car are an integral part of the car body that provide support and strength.
An Airbag is an active safety device commonly found in all modern day cars that automatically inflates in case of a collision. It imparts a cushioning effect for both the driver and the occupants to combat the impact of sudden thrust during an accident.

Benefit

It protects car passengers and driver during an accident by providing flexible envelope shielding them from major injuries.
An air dam is a huge air inlet in the car’s front bumper. It allows air to enter the car�s radiator to cool the fuming engine.

Benefit

Air dams help cool the car engine and also control the aerodynamic qualities of the car.
A type of vehicle suspension system that uses air springs instead of conventional steel springs. This system helps to maintain tyre position at an optimum angle that upholds traction control, steering control, braking, and even the acceleration. Powered by an engine driven or electric air pump or compressor Air suspension helps in providing a smooth ride quality and in some cases self-leveling.

Benefit

Air Suspension increases the friction between tyres and the road and offers greater control and stability to the driver.
Alloy wheels are made from an alloy of aluminium and magnesium unlike common wheels that are made of steel. They usually lighter in weight than the steel wheels. Alloy wheels are also better heat conductors than steel wheels and improve heat dissipation from the brakes, which reduces the chance of brake failure in more demanding driving conditions. They don�t require paint or wheel covers and instead add style to a car because of their shiny and intricate design.

Benefit

Reduces the weight of the car that in turn lowers the fuel consumption. More importantly, alloy wheels provide easy
balancing of the car as they are attached at the centre not like the steel wheels that are fitted at the edge of the rim.
Anti-Roll bars in a Car
An anti-roll bar helps the car to maintain balance and prevents the car from rolling during tight cornering. It does not affect the suspension stiffness when both wheels are deflected equally in the same direction. It is also called a stabilizer bar, an anti-sway bar, a roll bar, or an anti-roll bar (ARB). Its purpose is to try to keep the car's body from "rolling" during a sharp turn. It connects opposite (left/right) wheels together with short lever arms that are linked by a torsion spring.

Benefit

Anti-roll bars keep the car from rolling over when taking sharp turns.
Automatic Gear Box changes the gear automatically as the vehicle moves with the press of few buttons mounted on the steering wheel. Automatic transmissions are easier to drive and release the driver from the hassle of shifting the gears manually.

Benefit

Automatic transmission in car with a high power-to-weight ratio gives rapid, safe acceleration.
All Wheel Drive (AWD), or Four-wheel drive (4WD), or 4x4 ("four by four") are terms used to describe a four-wheel vehicle where the engine's power is transmitted to all four wheels simultaneously.

Benefit

In an All Wheel Drive (AWD) system, since the engine drives all the four wheels of the car, the road grip and control are better. An AWD provides a more stable ride in rainy weather.
