What is BAS?
Simply, a brake assist system monitors the driver’s use of the brake pedal, automatically sensing an attempt to stop the car as a result of panic.
It then provides very high braking power, even when the driver is only pressing gently on the brake pedal.

When this is used together with anti-lock braking systems, it success in faster and safer braking.

Depending on the driver, statistics for emergency stops in cars using this technology range from a 20% - 45% reduction in stopping distances, a potentially significant difference in critical situations.

Some road tests show that a driver requires up to 240 feet (73 meters) to stop a car heading around 60 mph (100 km/h).

 In the same circumstances, cars with brake assist were able to come to a complete stop in as little as 130 feet (40 meters).
Since it only takes one-fifth of a second to travel a car length at highway speeds, the superior speed with which the brake assist is able to react also accounts for its improved safety results over traditional braking systems.

A limited slip differential (LSD) is a modified or extracted type of differential gear arrangement that allows for some variation in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.

LSD Effect On The Road

The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all.

In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely

the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices.

For more demanding use, such as driving in mud, off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.
