These are the coolest places in the world where you'll find automakers developing their newest cars. Well, you could. If you were allowed in.
Ferrari has developed some of the finest road and race cars at their test circuit they built right behind their factory in the 1970s, so the track must be pretty damn great.

MIRA in the UK has everything from a notoriously destructive cobblestone road to an anechoic chamber. It would be a huge understatement to say that vehicles get tested thoroughly here.

GM's test facilities in Milford, MI includes the "Lutz Ring." The General's test track has an amalgamation of the best corners from race tracks across the world, and is so trying it takes GM employees years to be allowed to use it.
GM has had a streak of great handling cars in the Corvette Stingray and Z06, and the Camaro Z/28, so if you like those cars, thank this track.

Volvo's test track in Sweden is where the safest cars in the world are being developed. Volvo thinks they can eliminate all deaths in their cars by 2020 and they're doing it with extensive testing, all the way to simulating city streetcorners with a replica of Harlem.
Sadly, this one isn't really in use anymore, but holy crap, how awesome is a banked test track on the top of your factory!
Maybe not the most comprehensive track, but undoubtedly the coolest.
This 7.8 mile banked circle in Italy is where the fastest cars in the world come to test their top speed. It's so big, you can even see it from space.
What's better than a wind tunnel? A wind tunnel you can drive in. Chip Ganassi's race cars rip through here (long in secret) to hone their aerodynamics.
5th Gear called Arjeplog the "winter car testing capital of the world," which is a polite way of saying "hoon's paradise." It's where the handling and electronic aids of a car are honed, and where cars are tested in the most extreme low temperature conditions.
Three words: Alpine Handling Circuit. Millbrook has lots of different testing facilities, but the one you care about is the Alpine Handling Circuit.
And don't forget about the jump. Oh my god, the jump.

This once top secret track (built in what was a no-fly zone with East Germany) is the only place in the world where a supercar can hit its top speed. Too bad VW won't let other manufactures test there – I guess they're afraid of the reputation of their precious Veyron being ruined or something.
