2023 Lamborghini Huracan STO

5.2L V10

Naturally Aspirated V10

A free-breathing, high-revving V10 that screams to 8,000+ rpm with a flat-plane, hard-edged shriek and instant throttle response unmuffled by turbos. In the STO it is tuned for raw, motorsport-derived intensity rather than easy torque.

Shared between Lamborghini and Audi, it was the first all-new engine developed by Lamborghini after Audi's 1998 takeover, starting as a 5.0L in the 2003 Gallardo before growing to 5.2L. The engines are hand-assembled at Audi's plant in Gyor, Hungary.

• Each 5.2L V10 is hand-built from roughly 250 parts and takes about six hours to assemble.
• The Huracan marked the end of the line for this engine family, one of the last naturally aspirated V10s in any road car.
• The STO's tune drew directly on lessons from Lamborghini's Squadra Corse Huracan ST and GT3 EVO race programs.
