Okay, let's cover the most important bases first...
2.4l (not the 2.4 that was in the Neon SRT-4)
Limited slip diff
3 hood scoops
We don't know the price yet.
The price is probably a close held secret since it looks like this is not going to be the inexpensive pocket-rocket the Neon based SRT-4 was.
On the standard equipment list are things like:
Electronic Stability Program (ESP)
Brake Assist (system that gives you max braking if you hit the brakes partially but quickly - like in a panic stop)
Front, Front Knee, Side, and Head airbags
Power adjustable pedals
'Smartbeam' headlights that adjust their light to ambient lighting
Tire pressure monitor
