Spies got it – the 2015-2016 Mustang GT350R. They spied it beeing tested at Nurburgring. The video shows 2 Mustangs where the other one may be the less agrressive GT350.
Some say, that the sound you hear comes from the all-new flat plane crank V8 delivered from the current 5.0 Coyote. The power – around 500 HP.
