MIURA P40OSV

 

The P400SV was introduced in March 1971 at the Geneva motor show, alongside the Countach LP500 prototype. Exterior restyling was more evident than with the S. Wider rear wings and wheels, different tail lights, wider front grille and deleted eyelashes around the headlamps were all new. One of the biggest improvment was certainly front and rear chassis reinforcement and revised rear suspension providing a much better drivability. Later SV’s had separate lubrification system. Power was increased to 385 hp DIN.
