Not exact matches
The F 400 features a new active system that actually tilts the
wheels,
varying the camber
angle on the outer
wheels between 0 - 20 degrees, depending on the road surface.
But as more engine torque is called upon by the driver, the Haldex's electronic brain does the math by registering axle loads, tire slip and steering
angle, then commands the fast - acting electro - hydraulic center differential to continuously
vary torque distribution to enhance rear traction with a torque split that is biased to the rear
wheels by as much as 100 percent.
The heart of the technology is adjustable guide blades that
vary in
angle to most effectively guide engine exhaust flow onto the turbocharger's impeller
wheel.
Both suspension variants are combined with a new electromechanical Direct - Steer system featuring speed - sensitive power steering and a ratio that can be
varied across the steering
wheel angle and it also reduces the amount of steering required when parking and manoeuvring.
The rear steering
angle varies up to + / - 3.0 degrees, according to vehicle speed and driving mode selected: at low speeds the rear - axle steering
angle is opposite to that of the front
wheels (counter-phase steering), effectively shortening the wheelbase up to 600 mm for increased agility and a reduced turning circle for increased maneuverability.
The steering
angle of the rear
wheels can be
varied by up to 2.8 degrees, depending on vehicle speed.
Integral Active Steering will
vary the steering
angle of the front
wheels depending on steering
wheel movement,
wheel rotation speed, yaw rate and lateral acceleration, similiar to the way Active Steering works.
The standard progressive steering becomes more direct as the steering
angle increases; the new A6 also comes with dynamic all -
wheel steering - depending on the speed, the steering ratio
varies between 9.5:1 and 16.5:1, the rear
wheels steering as much as 5 degrees.
It comprises two electro - mechanical actuators at both sides of the rear axle (instead of conventional control arms) that allow the steering
angle of the rear
wheels to be
varied by up to about 1.5 degrees.
The heart of the technology is adjustable guide blades, which can
vary in
angle to most effectively guide engine exhaust flow onto the turbocharger's impeller
wheel.
The locking effect can
vary between 0 and 100 percent, according to the driving situation, and reacts to the car's steering
angle, accelerator position, brake pressure, engine torque,
wheel speed and yaw rate.
