A new supercar is brewing, one fully designed and engineered in Australia. We’re of course talking about the upcoming Joss supercar, a vehicle revealed in preview form at the 2011 Australian Motor Show in Melbourne this week.

These preview renderings displayed at the show reveal a fairly conventional supercar design, but that is to be expected as the Joss supercar’s lines are dictated more by aerodynamics and performance as opposed to aesthetics. For the design team, it’s what you cannot see that has been the primary focus.

Nevertheless, with an expected 500 horsepower 6.6-liter V-8 sitting in a carbon fiber and aluminum constructed chassis weighing around that magical 1,000 kilo (2,200 pound) mark, the Joss is shaping up to be a scorcher of a supercar. Some initial specs include a 0-60 mph time of under 3.0 seconds and a top speed of around 224 mph--we're talking faster than a Lamborghini Aventador LP700-4.

Low weight isn’t the only key to its performance. The Joss supercar will feature an advanced Albins Zeroshift Automated Manual Transmission, which is one the lightest and fastest shifting gearboxes currently in production.

Joss eventually hopes to build up to 25 examples of its new supercar--note a final name is yet to be decided--per year, each priced around the $500,000 mark.

For now, it’s still in the prototype stage, with JP1 (Joss Prototype 1) currently undergoing real world testing on Australian roads.
