HSV Gen-F Driver Preference Dial

Driver Preference Dial

The Driver Preference Dial allows the driver to control the following electronic systems in the vehicle without making the selection too complex:

ESC
Traction Control
MRC (where fitted)
Launch Control (manual only)
Electric Power Steering calibration
Bi-Modal exhaust
Torque Vectoring (GTS only)

Each model has different functions dependent on the electronic systems fitted to the vehicle however the function of the Driver Preference Dial is similar in each case – it is designed to increase vehicle performance with every clockwise turn of the dial.

Torque Vectoring

Currently only fitted to just a few exclusive global marques, HSV’s brake Torque Vectoring helps reduce understeer by generating a “rotational moment” in the rear axle when the vehicle is under power. The vehicle’s Electronic Stability Control system detects the understeer event, applies braking to the inside rear wheel and transfers torque to the outside rear wheel.

(A “moment” is a measurement of force being applied over distance).

HSV Gen-F AP Brakes

AP Brakes

All GEN-F vehicles feature a brake package which was developed using NASCAR and V8 Supercar technologies. This brake package not only offers a weight saving, but also superior brake feel and performance.

Increased brake rotor diameters have enabled improvements in brake modulation and feel, making for a more responsive brake package.

The GTS brake package features a “radical” low weight caliper design allowing for a larger, higher performing caliper without sacrificing unsprung mass.

Generation 3 Magnetic Ride Control

Magnetic Ride Control (MRC) is a semi-active suspension system, which responds to road inputs and driving conditions in real time based on information from sensors mounted to the vehicle.

The Generation 3 MRC system, which was developed by HSV in conjunction with BWI Group, uses a 2 coil tapered slot piston design for front and rear dampers. This means that two coils are used per damper instead of one, making the Generation 3 system twice as fast as the Generation 2 system.

Generation 3 MRC features 2 independent settings on Senator Signature and Grange being, Touring and Sport. In addition to these 2 independent settings, GTS also features a Track setting.

The system delivers an improved level of body control while achieving improvements in ride quality and wheel control.

Continental Tyres

Continental Tyres

For the GEN-F program, HSV researched a number of potential tyre suppliers. After an extensive evaluation and testing process, in both dry and wet conditions and involving the HSV Engineering team and HSV Test Driver and V8 Supercar Driver, Garth Tander, Continental was chosen as the tyre supplier for the GEN-F range.

Electric Power Steering

Electric Power Steering matches steering calibration with MRC and ESC settings, providing an improved level of “feel” through the steering wheel that can be changed to suit driving preferences. The feature is also a fuel saving system as the engine is no longer used to drive a hydraulic pump.

Launch Control (Manual transmission only)

Once enabled by the driver through the Driver Preference Dial, Launch Control will provide the vehicle with the ability to accelerate, from standstill, at its maximum potential regardless of the skill or experience of the driver. Available on all GEN-F manual vehicles, this feature takes the guess work out of transferring torque to the ground.

This unique system uses the ESC unit to control the engine by requesting torque from the Electronic Control Unit. The ESC unit will continue to dictate the engine torque, relative to rear wheel slip, for maximum acceleration. Wheel slip ratio is also unique for the Launch Control feature.

Competition Mode - Electronic Stability Control (ESC)

We all know ESC as a positive safety feature that provides computer intervention when a driver pushes a car into a corner (or similar manoeuvre) at a speed that exceeds the vehicle's cornering or handling capabilities. While a great safety feature, it is also a source of frustration to a skilled driver in an HSV vehicle which has clearly been designed to provide a high level of driver input and excitement, especially in controlled conditions (for example on a race track).

To address this, HSV, in conjunction with Bosch, developed a uniquely calibrated “Competition Mode ESC” system.

Competition Mode ESC is specifically designed to give the driver more freedom under ‘spirited’ driving conditions. This ESC calibration allows the driver to attack corners more aggressively; permitting more oversteer and understeer, before an intervention. The ESC interventions are more progressive to ensure the driver can get the most out of his car.

We like to call it ‘giving confidence beyond ability’ – with the ESC working away in the background, ready to catch the driver once ability runs out. When used correctly, Competition Mode ESC will allow the driver to improve his lap times over the standard ESC setting.
