Lamborghini Reveals the Huracán Successor's Engine: A Twin-Turbo V-8 That Revs to 10,000 RPM

Lamborghini is being characteristically coy about its impending Huracán successor ahead of the car's reveal later this year — but the company is finally starting to show its cards. The new supercar's name remains a mystery (although we know CEO Stephan Winkelmann has already chosen it), but on Monday, the company revealed the project is code-named Lamborghini 634. More notably, instead of a naturally aspirated V-10, the new Lambo will sport an all-new hybrid-assisted twin-turbo V-8 — one that revs all the way to 10,000 rpm.

To be precise, the new motor is a 4.0-liter flat-plane-crank V-8 packing two turbochargers and three electric motors, and paired with an eight-speed dual-clutch transmission. But power delivery should be true to traditional high-revving Lamborghini form; the engine's maximum power of 788 horsepower arrives between 9,000 and 9,750 rpm, while peak torque of 538 lb-ft arrives between 4,000 and 7,000 rpm. However, since the battery and those electric motors account for 221 lb-ft of the torque mix, off-the-line performance shouldn't be an issue.

The hybrid engine is an all-new, clean-sheet design with a herculean task ahead of it: surpassing the intense noise and emotions associated with the wailing V-10, which became increasingly notable during the Huracan's 10-year production run. That said, the specifications of this new engine hint that the V-8 should deliver its own unique blend of performance and sound.

At least, the brand seems keen to assuage any worries about the engine's character. "The characteristics of the new V-8 intensify in a crescendo that at high revs reaches its peak in terms of volume and frequency content and this, in harmony with the vibrations transmitted to the chassis by the flat-plane crankshaft, creates an all-encompassing sensory experience," Lamborghini's announcement says.

Prospective buyers and supercar enthusiasts alike can look forward to the Huracán's successor launching later this year. The Lamborghini 634's debut will mark the third stage in the carmaker's hybrid push, following up on the Lamborghini Revuelto as well as the newly launched Lamborghini Urus SE. Suffice it to say, electrification continues to be an exercise in performance as much as efficiency for the legendary Italian brand.
