Lamborghini Teases High-Revving Twin-Turbo V-8 for Huracán Successor

Lamborghini reveals details of the Huracán successor’s 10,000 RPM twin-turbo V-8 and hybrid system, promising thrilling performance ahead of its August debut.

With the end of Huracán production, Lamborghini’s iconic V-10 will be retired. However, Lamborghini is not stepping back from making thrilling engines. On Monday, the Italian automaker revealed the first details of the Huracán successor’s twin-turbo V-8, and it sounds highly promising.

The standout feature is its 10,000-rpm redline, remarkable for any engine, let alone a turbocharged one. Only the Mercedes-AMG One, Aston Martin Valkyrie, and Gordon Murray Automotive’s T.33 and T.50 rev higher.

This new 4.0-liter engine produces 789 horsepower between 9,000 and 9,750 RPM and 538 pound-feet of torque between 4,000 and 7,000 RPM. It’s Lamborghini’s first flat-plane V-8 and features a «hot-vee» configuration, with the turbos situated in the valley between the cylinder banks. It’s dry-sumped for proper lubrication in all conditions and direct-injected.

Achieving such high revs requires a light rotating assembly, so this V-8 uses titanium connecting rods. Lamborghini has replaced traditional bucket-and-shim tappets with rigid finger followers, a setup common in racing engines and sport bikes, but also used by Ferrari, Porsche, and Ford for some of their high-performance engines.

Complementing this engine is a hybrid system similar to that in the new Revuelto. The V-8 is paired with an electric motor providing 147 hp and 221 pound-feet of torque, integrated between the engine and the eight-speed dual-clutch transmission. Unlike the Revuelto, where the motor is atop the gearbox, the Huracán successor’s motor is traditionally placed between the engine and transmission. It’s an axial-flux motor, narrower than conventional electric motors, also used by McLaren and Ferrari in their hybrid models.

Lamborghini indicates the Huracán successor features a three-motor hybrid system, likely with a motor for each front wheel, similar to the Revuelto. However, specific details are yet to be disclosed.

Currently, Lamborghini is already racing this V-8 in the SC63 LMDh prototype, where it displaces 3.8 liters and uses a different hybrid system. The full reveal of the Huracán successor is expected in August.
