Lamborghini is set to unveil the replacement for its Huracan supercar in August this year, with a launch planned before the end of 2024. Codenamed 634, the new car will take aim at the Ferrari 296 GTB and McLaren Artura.
At the heart of the 634 is a newly developed, twin-turbocharged 4.0-litre V8 engine. This powerhouse produces a mighty 800PS and 730Nm of torque on its own, eclipsing even the most potent version of the Huracan’s naturally aspirated V10. But the real headline-grabber is the redline – a stratospheric 10,000rpm, a figure Lamborghini describes as “normally reserved for racing engines.” This will make the 634’s engine the highest-revving V8 in any current production car, only challenged by a select few hypercars like the Mercedes-AMG One and Aston Martin Valkyrie.
Unlike the Audi-derived V8 found in the Lamborghini Urus, the 634’s engine is a clean-sheet design, developed entirely by Lamborghini. The Italian marque went to great lengths to ensure the new engine possesses a “unique and distinctive character,” promising drivers an unparalleled experience.
The 634’s hybrid powertrain pairs the V8 with a lightweight, axial-flux electric motor positioned between the engine and the eight-speed dual-clutch automatic gearbox. This motor contributes an additional 150PS and 300Nm to the rear axle. While Lamborghini remains tight-lipped on the total combined output, it’s expected to be well over 900PS.
The 634’s drivetrain is quite different from the V12-powered Revuelto, which uses two electric motors on the front axle and one within the gearbox. However, the 634 is expected to share the Revuelto’s placement of the traction battery within the transmission tunnel for optimal weight distribution and packaging.
The switch to a plug-in hybrid system promises significant improvements in handling dynamics. “The package itself is much better than a normal internal combustion engine car,” said Lamborghini sales and marketing boss Federico Foschini. The electric motor allows for active torque vectoring, which enhances the car’s agility and unlocks the full potential of the engine.
Visually, the new supercar will share a clear lineage with the flagship Revuelto. Expect a dramatic silhouette that embodies the brand’s “spaceship” design philosophy, alongside Lamborghini hallmarks like the gaping hexagonal exhaust, Y-shaped LED lights, and prominent air channels that channel airflow for increased downforce.
The 634 is likely to borrow the basic principles of the Revuelto’s carbon fibre monocoque, but it will likely use more aluminium in its construction to keep costs down. This aligns with the Huracan’s construction, which used a carbon fibre central tunnel and rear bulkhead but relied on aluminium elsewhere. The platform will also be shortened to differentiate it from the larger Revuelto.
