Following the announcement of the restyled new HSV Grange WM3, Holden Special Vehicles has also introduced its all-new touch screen performance data interface.

Fitted as standard equipment to the Grange, the Enhanced Driver Interface (EDI) system constantly streams real-time vehicle dynamics and performance information to the touch screen in the centre console.

The EDI system has been developed in partnership with industry specialist Motec while the graphics and display were designed in-house by HSV’s styling department.

“Our customers are passionate about driving, and this system is about delivering race bred technology in a new engaging way that is relevant to a road car,” HSV’s Managing Director, Phil Harding said.

“We are confident our customers are going to love the way they can access data, and interact with their car.”

Similar to the system in the Nissan GT-R, the HSV EDI system is comprised of 11 different sections of information: Driver, Race, Stopwatch, Data Logging, Stability, G Force, Dynamics, MRC, Gauges, Bi-Modal Exhaust, and Side Blind Zone Alert (SBZA).

The G Force page displays longitudinal and lateral G force while the Driver page displays a combination of driver inputs including RPM, gear selection, and accelerator and brake positions.

The EDI system gets very interesting when you switch over to the Race page where it utilises GPS technology to display track maps, record lap times, record fastest lap, as well as lap gain and loss with most Australian race tracks already programmed into the system such as Bathurst.

For simpler racing scenarios such as hill climbs or even just the daily commute to work, the Stop Watch page provides a simple way to keep track of time.

The Dynamics page is similar to the G Force page, although it uses sensors to identify and display oversteer and understeer.

A Gauge Selection page allows you to display your preferred gauges on-screen, with drivers able to choose from Instant Fuel Economy, Intake Air Temperature, External Air Temperature, Torque, Power, Manifold Pressure, Elevation, LPI Level (on LPI only), and Exhaust Pressure (on cars with Bi-Modal Exhaust only).

“One of the challenges with designing the graphics is in making the data accessible to the driver,” HSV’s Chief of Design and Styling Julian Quincey said.

“For instance, it is not terribly engaging to get a whole stream of data in the form of numbers or a line graph. If you are a race driver you get used to that, but in a road car it needs to be more intuitive.”

“Making the display intuitive was the most important thing for us during the development process, and it really required a whole new level of integration between design and engineering.”

A Fuel Economy page provides detailed information on fuel economy history, and for Granges with LPI will incorporate combined petrol and LPG fuel ranges.

The Bi-modal page allows the driver to select the exhaust modes, choosing from normal, idle off, and off.

Finally, a Side Blind Zone Alert page allows you to turn off your Side Blind Zone Alert if you choose.

HSV is yet to release official confirmation on when the  Enhanced Driver Interface (EDI) system will be available in the rest of the HSV range.
