This can be contrasted with steer, which is the antisymmetric angle, i.e. both wheels point to the left or right, in parallel (roughly). Negative toe, or toe out, is the front of the wheel pointing away from the centreline of the vehicle. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle. [2]

The most common example is probably the 4×4 configuration. 6×4*4 is the chassis configuration for a vehicle with six wheels where four wheels are driven, in addition, the two front wheels as well as the rearmost two wheels are steered. In this case it is a three-axled vehicle. Often the formula A × B × C is used.
Locking hubs, also known as free wheeling hubs are fitted to some (mainly older) four-wheel drive vehicles, allowing the front wheels to rotate freely when disconnected (unlocked) from the front axle. This is done to reduce the mechanical resistance of the front-portion of the drivetrain when four-wheel drive is not in use. [1]
An example used by bicyclists is that during the descent of a hill, approximately three hair dryers' worth of power or some two horsepower is lost to Air drag at terminal speeds. [citation needed] Regenerative and friction braking must both be used, creating the need to control them to produce the required total braking.
An inboard brake is an automobile technology wherein the disc brakes are mounted on the chassis of the vehicle, rather than directly on the wheel hubs. Its main advantages are twofold: a reduction in the unsprung weight of the wheel hubs, as this no longer includes the brake discs and calipers; and braking torque is applied directly to the chassis, rather than being transferred to it through ...
The BMW active steering system utilizes a double planetary gear system located at the base of the steering column to facilitate driver independent steering of the front wheels. The system is intended to offer two principal benefits; a variable steering ratio and stability-enhancing corrective steering actions.
An illustration of a wheel with negative camber. Camber is a measurement from the centerline of the wheel/tire relative to the road's surface. Negative camber is when the top of the wheel/tire angles inward toward the center of the vehicle. When done sparingly, negative camber greatly improves the handling characteristics of a vehicle.
