Well, I was waiting for someone else to post, but I'll just go ahead and post it. Country vs Country!
Representing America, we have the new Chevrolet Camaro Z/28
With an MSRP just under 75,000 USD, this car is the cheapest on the list, but don't let that dissuade you. The engine is a 7.0 V8 with 505 horsepower, 481 ft-lbs of torque, and a six-speed manual transmission.
Still not sold? Well, this Camaro also features 14 inch Carbon-Ceramic Brake discs that'll stop it almost as fast as the engine can make it go.
Now, from Germany, we have a car with stunning looks and amazing performance, the 2014 CL63 AMG.
This car has a 5.5 Biturbo V8 rated at 536 horsepower and 590 ft-lbs of torque. That gets to the wheels via a 7 speed automated manual transmission. And at a starting price of 154,600 USD, that's quite a deal.
Unfortunately, I can't find any information on the brakes for this, or any other of the contestants. If anyone can find out the data for them, that'd be great.
For Japan, we have none other than Godzilla himself: the 2015 GT-R.
This car has a 3.8 liter Twin Turbocharged engine featuring an astounding 545 horsepower, as well as a six-speed, dual clutch, sequential transmission. It also features all-wheel drive. This car is bested on the drag strip by only a handfull of other supercars, all of them costing much more than the starting price of 101,770 for this GTR.
Now, for Italy, I was going to do the new California, but it's double the cost of the above GTR, so instead, we have a 2005 Ferrari F430 Berlinetta.
All the information about this car is in this link:

The engine makes 490 horsepower, and the transmission is what I'm assuming to be a six-speed manual.
