Years before a Ford vehicle shines on stage at a car show or arrives in dealer showrooms, Ford researchers are hard at work behind the scenes, building virtual vehicles that allow the company to design, analyse and enhance the driver experience before a physical vehicle ever exists.
Known as the Powerwall (Trekers would have preferred the term Holodeck, maybe next time) the new Virtual Reality Centre houses a 6m x 3m screen used to evaluated 3D models of proposed cars.
According to Ford the result is a superior mark of craftsmanship and refined finish that characterises Ford vehicles. The virtual process also speeds up production times while helping reduce costs. Using virtual reality tools, engineers and designers can make consumer-friendly adjustments before the building of a vehicle starts.
The Ford Australia VRC is one of just three in the company’s global design centres. The other two are in Dearborn, Michigan and Cologne, Germany.

“In this virtual world, we can evaluate early vehicle design and its engineering against a backdrop of virtual conditions and literally experience a complete vehicle years before it is built and a customer drives it out of the showroom,” according to Adam Frost, Chief Engineer, Global Engineering Services and APA Digital Innovation at Ford Motor Company.
“This helps us to create a car, pickup or crossover that provides the perfect environment for the driver and its occupants. From a customer’s perspective, before even out first prototype is built, this allows us to finely tune the customer experience.”
The VRC is capable of real-time image manipulation, with realistic shading, shadow generation and textural mapping.
Powerwall technology creates not only life-size static images for detailed reviews of new models but also full virtual animation shows. Operators can show the vehicle moving, the doors opening and closing, the instruments functioning and the driving controls operating.
“Digital reviews will also allow Ford to introduce higher quality levels at earlier stages in the design and product development process,” he said.

“The virtual vehicles are built up from Ford’s own engineering and design computer files. The modelling is so accurate that you can see internal components and the even the cut-pile of an interior carpet or detailed alloy-look clutch, brake and accelerator pedals.” Said Frost..
The Ford Australia VRC is a purpose-built windowless room which contains tracking cameras and two car seats and a mock steering wheel assembly, which is called a buck. The buck sits inside a framework of 16 motion tracking cameras that respond to reference markers on the virtual reality helmets worn by those sitting in the mock car interior.
The high-tech VRC gives the Ford Australia design and engineering teams world-class status. Combined with the company’s engineering and powertrain expertise at its Campbellfield headquarters, Ford Australia is a recognised centre of excellence in the Asia Pacific and Africa region.
Ford virtual reality world even extends beyond the design and engineering of vehicles to the factory floor. Ford of Europe is developing a complete virtual factory to simulate the end-to-end assembly line production.
Virtual factories will enable Ford to preview and optimise the assembly of future models at any of the company’s plants, anywhere in the world.
The company’s Valencia plant, in Spain, is taking the lead in developing virtual factory environments, which have the potential to enable remote evaluations to be conducted from around the globe.
Special projectors and polarising, motion-sensing glasses are used to create interactive 3D virtual reality manufacturing scenarios.
The actions required by real-life assembly line operators are simulated inside these environments to help Ford ergonomics experts eliminate strenuous postures and optimise individual aspects of the assembly process.
Ford’s ergonomics experts in Cologne, Germany, use computer simulations to scrutinise the fitment process for even the smallest components, and analyse whether changes are required to make the task as straightforward as possible for the assembly-line operator.

- * Hardware output - D-Port converted to DVI-D
- * Cooling - Clipsal fan tray 19-inch fan 600mm x 600mm
- * NVIS SX-60 Virtual Reality and ST-50 Augmented Reality Head Mounted Displays (immersion headsets)
- * Multiple Displays - 24-inch Dell U2410 and 46-inch JVC GD-463D10 3D LCD Monitors
- * 48 GB RAM
- * Intel Xeon CPU X5690 3.46 GHz (2 Processors)
- * How much computing power? Apollo 11’s computing power is said to have been 2.048 MHz. The VRC has almost 1700 times more computing power.
- * Rendered images fully generated from CAD (Computer Aided Design) data
- * 190,000 different geometric CAD items that make up a vehicle, for example the Ranger pickup
- * Everything that makes up the vehicle is designed in 3D using computer aided design, full size, located correctly in the 3D world on computer
- * All surfaces visible to the customer are crafted and created by Ford industrial design / design / styling team
- * When all iterations of these 3D items are added up, almost 10 million optimisations were made for Ranger before a final design was signed off
- * These parts were checked 26,000 times for geometric compatibility during the program to ensure parts all fit together in the real world
- * Surface Accuracy of data : 0.005 mm (compared to human hair 0.1mm)
- * 40 virtual gateways (deadlines to be met during virtual design phase)
- * Over 55 Terabytes (TB) of computer data makes up the geometry of the Ranger
- * When viewing the entire car on a computer software is used that simplifies the geometry so that is easier for the computer to work with. This converts the vehicle into 1 billion triangles - tiny triangles are easier for the computer graphics systems to rotate/visualize
- * Computer Aided Engineering (CAE = simulation) models break the car up into 2 million elements (small squares)
- * Almost 44 TB of computer simulation (CAE) data was outputted from Ford supercomputers during virtual proving ground testing of Ranger
- * Using these models, 9000 virtual crash tests were performed
