The Maserati Birdcage 75th was produced by Maserati and displayed at the 2005 Geneva Auto Show as a concept car. The car features a 6.0 Liter V12 engine producing 700 horsepower. This concept vehicle is based on the Maserati MC12, with a slight difference, the Birdcage is more of a dream car and probably won’t see it till 2025.
