It also responds more smoothly, especially at low revs and very light throttle openings.

In automatic mode, sensors seamlessly divide the power among the wheels according to road surface, throttle opening, rate of acceleration and cornering force.

The 1953 and later units when in "Drive" started in low and automatically up shifted to high at a speed determined by the throttle opening.

The ECU determines the throttle opening based on accelerator pedal position and inputs from other engine sensors.

The boost threshold is determined by the engine displacement, engine rpm, throttle opening, and the size of the turbo.

Our only criticism was a slight exhaust resonance at small throttle openings and low revs.

Cylinder lubrication is necessarily total-loss and this inevitably leads to a smokey exhaust, particularly on wide throttle openings.

Partly this is achieved by the engine operating on just four of its eight cylinders under light throttle openings.

As the pumps outlet is restricted, the load increases and the throttle is simply opened until at the desired throttle opening.

These include an automatic twin-clutch transmission and fuel-saving cylinder shut-down on low throttle openings.
