Whatcha got for us today, Best Motoring? A battle between the 997 Carrera S, the coveted E46 M3 CSL, the V10 M5, a Nismo-tuned Skyline R-34, and a Lamborghini Gallardo? Okay, fine.

It's tough to pick a favorite in this test. All of these cars are pretty amazing in their own ways, and all of them make extensive and liberal use of lightweight materials.

The battle itself can be found on this second video. Who takes home the glory at Tsukuba Circuit? You'll have to wait and see. It's a close one.
