A few fast laps of Sydney Motorsport Park in a McLaren P1 has even the McLaren Instructor surprised by the sheer violence of it's acceleration. Especially when 'DRS' is activated on the last straight!!
Under DRS, the car hit 270kph at the 300m braking board for T1!! It's an astonishing car and still looks current despite nearly 10 years old. Still my pick, even over the Senna ;-)
