As the Huracán production ends, Lamborghini’s acclaimed V10 engine will step down. Nevertheless, the brand remains dedicated to engineering thrilling powertrains. Lamborghini has released initial insights into the twin-turbo V8 of the upcoming Huracán successor, and it appears quite promising.
Its most notable attribute is the remarkable 10,000-rpm redline, a remarkably high figure for a turbocharged powerplant. This places it in esteemed company, alongside the Mercedes-AMG One, Aston Martin Valkyrie, and Gordon Murray Automotive’s T.33 and T.50, which also boast higher rev limits. This fresh 4.0-liter engine produces 789 hp between 9,000 and 9,750 RPM, along with 538 pound-feet of torque between 4,000 and 7,000 RPM.
This engine, Lamborghini’s inaugural flat-plane V8, showcases a “hot-vee” layout with turbochargers positioned in the valley between the cylinder banks. It’s designed with a dry-sump system for optimal lubrication and direct fuel injection. To attain its high rev ceiling, the V8 employs titanium connecting rods and a valvetrain outfitted with firm finger followers, a configuration typically found in racing engines and motorcycles, enabling elevated engine speeds.
Accompanying this powerplant is a hybrid setup akin to the one featured in the new Revuelto. The V8 partners with a 147-hp electric motor that delivers 221 pound-feet of torque, integrated between the engine and the eight-speed dual-clutch transmission. This setup, also present in the Revuelto, places the electric motor in the conventional position between the engine and transmission. The axial-flux motor, narrower than conventional electric motors, is a standout feature utilized by McLaren and Ferrari.
The successor to Lamborghini’s Huracán will feature a three-motor hybrid configuration, likely with motors for each front wheel, mirroring the Revuelto. Further particulars are yet to be disclosed. Presently, Lamborghini is field-testing this V8 in the SC63 LMDh prototype, where it displaces 3.8 liters and employs a distinct hybrid system.
The grand reveal of the Huracán’s successor is slated for August, promising an electrifying addition to Lamborghini’s range. This innovative twin-turbo V8 powerplant showcases Lamborghini’s commitment to merging heritage with state-of-the-art technology.
