The last and most powerful Urraco produced, the P300 was unveiled in 1974. Lamborghini increased the size of their new V8 engine to 3 Liters, and with it, boosted power to 247hp. Subtle styling tweaks were made, most noticeably the satin black louvers on the front and rear deck lids. At the end of Urraco production, just 190 P300s were made.
