Emission Systems And Parts

I like to make up new car designs in my spare time. Here's one that I came up with:

Buick X9 (I think it's cool when unlikely brands produce performance cars)
-A sleek, luxurious, rear engine, rear wheel drive super car
-Wing doors and quad flip-up headlights
-$220,000 price tag
-Low profile Pirelli tires
-6-speed manual trans with gated shifter
-Digital display dashboard
-Mock Leopard print leather bucket seats
-Chameleon paint job that changes from dark purple to dark blue
-Lots of exterior air vents
-Frilled roof line with electronically operated top that opens up
-4.8 GM Vortec V8 w/twin intercooled screw superchargers (producing a combined total of 15psi boost)
-Titanium headers and dual exhaust with Borla mufflers that empties into six stainless tips
-Engine produces 577 horsepower and 650lb ft of torque
-Top speed of 199mph (electronically governed)

What's your exotic car idea? Rules: it has to be made by a real car manufacturer.
