After carrying out a little more research, it would appear thst the Erebus Racing Team were already in existence last year, i.e. 2012. It would also appear that quite a number of the cars are built by a particular organization, the name of whom escapes me for the moment. It would also appear that all teams (?) use the same wheels and, of course, Dunlop tyres. Furthermore, gearboxes are now located at the rear in form of transaxles - thus, both diffs and gearboxes come as one unit and, again, I believe that all teams use the same layout.
This then begs the question, as to the extent of involvement by Mercedes in general, and AMG in particular, in this race series. Are we merely looking at engine exclusive set-up to the teams (Nissan, AMG, Ford, Holden), whilst the rest is more or less the same ? I pose these questions not to belittle the series, but more of an effort to understand it all, and as to how it works. I'd be interested in others' opinions. Regards Styria
What is different about a 2013 COTF car versus a current V8 Supercar?
--Chassis design and specification will now be fixed. All chassis to be dimensionally identical, but different accredited vehicle builders can construct them.
--Engine is mounted 100mms further back and down. Protects engine in case of frontal impact and improves weight distribution.
--Increase in wheel and tyre size to 18-inch provide by Dunlop. Bigger brakes can therefore also be fitted.
--Windscreen becomes polycarbonate. It’s 250 times stronger than glass.
--Collapsible steering column with collapsible section in the engine bay, rather than the cabin.
--Different transmission, moving to a transaxle, which incorporates the differential and gearbox in one assembly.
--Adoption of IRS (Independent Rear Suspension) with control pickup points and a control specification of uprights and wishbones.
--Fuel cell moved further forward in the car to protect from rear impacts.
The COTF will look the same from the outside, still make that unique V8 Supercar growl, and the best drivers from this part of the world, and sometimes the other, will still be fighting it out for the title.
The Car of the Future regulations essentially call for a single ‘control’ chassis, which is common to all teams. Engines and styling, though, are unique.
While Ford and Holden teams rely on racing V-8 engines from their respective American parents, Nissan will be using a Nismo-tuned version of the V-8 in the Infiniti M56.
The Mercedes touring cars will be powered by a modified, 5.0-litre version of the 6.3-litre V8 currently used in the SLS AMG GT3 race cars. Erebus is paying AMG to develop the engine and other parts of the car.
The engines need to displace no more than 5.0 litres and have an rpm limit of between 7,000 and 7,500 revs. Output also needs to be limited to around 650 horsepower, and torque curves need to be in parity across all teams.
I hope this gives you a better idea.
