Brake Force Display is a system developed by BMW for alerting tailgating drivers of a potential hazard in front of their vehicle. It works by increasing the intensity of the brake lights under heavy braking. The extra lighting is triggered only after the ABS sensors detect a rate of deceleration in excess of 5 m/second […]
BELT FORCE LIMITERS – Belt force limiters
The belt force limiter is located inside the inertia reel on the belt housing and consists of a torsion bar. When a force exceeding a certain level acts on the belt strap, the torsion bar produces a controlled reduction in the locking effect of the inertia reel. In other words, it automatically limits the stress […]
BAS – Brake Assist System
This Brake Assist System (BAS), developed by Mercedes-Benz to shorten emergency stopping distances, takes over if a driver doesn’t apply enough braking power in a critical situation. The system automatically develops maximum brake boost, thus reducing the actual stopping distance by a significant margin (according to Mercedes-Benz in-house tests, by almost 45%).
6×6 – 6×6
An expression used to describe a vehicle equipped with six wheels that is driven by all of them.
6×4 – 6×4
An expression used to describe a six-wheeled vehicle – two wheels in the front and four in the rear – that is driven by the rear four wheels.
4X2 – Two Wheel Drive
This expression is used to describe a vehicle with only two wheel drive. The first figure is the total number of wheels, and the second is the number of driving wheels. In some countries it’s essentially a different name for rear-wheel drive vehicles (RWD), unlike 2X4, which can be used for describing a front-wheel drive […]
4WD – Four Wheel Drive
Four Wheel Drive is a system which transfers engine power to four wheels independently and is mostly found on SUVs and all-terain vehicles. By using differentials it can transfer almost any amount of power percentage to any of the four driving wheels.
4MATIC – 4 Wheel Drive and Automatic
4MATIC is the name of a complex electronically controlled all wheel drive system developed and used by Mercedes-Benz on some of its models. All Mercedes cars featuring this system also have an automatic transmission in standard equipment and that’s where its name is derived from (4-wheel drive and automatic transmission). Originally developed together by Mercedes […]
4ETS – 4 wheel Electronic Traction System
Working with the vehicle’s full-time four-wheel drive, 4-ETS uses individual wheel-speed sensors to detect the onset of wheel slip. Then it individually brakes the slipping wheels as needed, providing the effect of locking the front, center and/or rear differentials. The 4-ETS system continually balances the torque split to direct power to the wheel or wheels […]
AYC – Active Yaw Control
The Active Yaw Control is a Mitsubishi developed system that stabilizes the yaw moment during hard cornering. By simulating a torque differential between the right and left driving wheels, the AYC system on the Mitsubishi EVO models improves cornering performance and lateral stability on most surfaces.
