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

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).

AP Racing Brakes

AP Racing Brakes

All HSV vehicles feature a brake package which was developed using NASCAR and V8 Supercar technology.

Featuring 367mm x 32mm front discs and 372mm x 28mm rear discs, a 4-piston brake package is standard on the ClubSport R8 LSA, ClubSport R8 Tourer LSA, Maloo R8 LSA and Senator Signature. This package offers an outstanding strength-to-weight ratio, along with superior brake feel and performance.

Standard on GTS, and now available as an option on ClubSport R8 LSA, ClubSport R8 Tourer LSA, Maloo R8 LSA and Senator Signature, is a 6-piston brake package. With 390mm x 36mm front discs and 372mm x 28mm rear discs (4-piston calipers), this brake package features a “radical” low weight caliper design allowing for a larger, higher performing caliper without sacrificing unsprung mass.

Exclusive to the GTSR range is a new AP Racing Premium 6-piston brake package which pushes AP Racing radical design to an all-new level.

Employing Monoblock calipers with massive, 410mm diameter front rotors, this new brake package delivers enormous stopping power, improved brake modulation and an even firmer pedal feel.

The new 410mm diameter front rotor is a fully floating design, using technology derived from race-cars but refined for the road. The disc bell is made from forged aircraft-grade aluminium for a superior strength-to-weight ratio, while the 410mm rotors share race-car inspired cooling technology, using the “s-vane” design.

The improved strength-to-weight ratio of the 6-piston monoblock caliper allows for a thinner section on the caliper bridge allowing for the fitment of the 410mm rotor inside the 20” wheel.

Generation 3 Magnetic Ride Control (Senator Signature, GTS and GTSR only)

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.

At the heart of MRC is a central controlling unit that updates each damper every 1,000th of a second to the slightest change in road conditions or driving style. The MRC system consists of Magneto- Rheological* (MR) fluid-based monotube struts, monotube shock absorbers, a position sensor set and an onboard controller.

By controlling the current to the electromagnetic coils in the piston, the MR fluid’s consistency can be changed, varying the resistance to fluid flow and damping force. Generation 3 MRC features 2 independent settings (“Touring" and "Sport”) on Senator Signature and an additional “Track" setting on both GTS and GTSR.

The system delivers a superior level of body control while achieving outstanding ride quality and wheel control.

SupaShock Suspension (W1 only)

SupaShock Suspension (GTSR W1 only)

This race-inspired suspension system is taken from the Walkinshaw Racing Supercars and refined for on-road driving. This is, quite simply, the complete performance package with the suspension tune undeniably track focussed.

The front strut is a monotube upside-down configuration with the damper shaft and bump rubber contained within the strut leg. Lateral and longitudinal loading is controlled through a series of “du-style” bushes contacting the damper outer case. This design removes any side load from the damper shaft and increases the rigidity and response of the system.

Internal components come straight from the racing industry with linear/linear style damper pistons.

The front spring is a coil-over design rated at approximately 2.2 times higher than the balance of the HSV model range.

Other mounting hardware is retained from the regular HSV range to ensure an appropriate level of comfort and refinement.

The rear damper is very similar in construction to the front strut, with the same style “du” bushes to control side load. Again, original mounting hardware is used top and bottom to maintain an appropriate level of refinement.

This damper delivers the lowest frictional losses of any commercial damper available.

Continental ContiSportContact 5P (All Models excl. GTSR W1)

HSV adopted the ContiSportContact 5P tyre at the introduction of the GEN-F range in 2013.

This tyre was chosen after extensive testing by the HSV engineering team and after evaluating tyre compounds from all of the world’s leading suppliers. After an extensive evaluation program, featuring input from Walkinshaw Racing drivers, the ContiSportContact 5P stood out as offering superior dry and wet weather performance and the finest balance between road holding, grip and ride comfort. Steering response, tyre stability and handling balance were also critical components of the evaluation.

Pirelli P Zero Trofeo R (GTSR W1 only)
It is important to note that this Pirelli tyre has been specially chosen for its track potential. These tyres have a special thread and compound that is optimised for dry road performance. While these tyres are suitable for use in damp/wet conditions, HSV recommends the vehicle should be driven with caution, and driving conditions respected, as under these conditions, the tyres may not offer the same level of grip as standard passenger vehicle tyres.

Pirelli P Zero Trofeo R (GTSR W1 only)

The GTSR W1 is built for the track. And, as such, HSV’s engineers sought a tyre compound that would help ensure we maximised the potential of the powertrain and suspension settings.

After much evaluation, the Pirelli P Zero Trofeo R track-tyre was chosen for exclusive fitment to GTSR W1.

The Pirelli P Zero Trofeo R is essentially a road-legal race tyre that delivers excellent performance, especially in dry, track-like conditions. Not normally found on the average road car, this tyre is all about getting power to the ground and, as drivers will appreciate, it seems the harder you push this tyre, the better the grip levels become.

Electric Power Steering

Electric Power Steering matches steering calibration with ESC settings, providing an optimum 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 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.
