Lamborghini has revealed that its highly anticipated codenamed 634 model, the successor to the Huracán, will feature a new hybrid twin-turbo V8 engine. This new addition to Lamborghini’s High-Performance Electrified Vehicle (HPEV) lineup showcases a significant leap in engineering and performance.
The engine is a clean-sheet design from Lamborghini’s headquarters in Sant’Agata Bolognese, Italy. It combines a twin-turbo V8 with a hybrid system incorporating three electric motors and an eight-speed dual-clutch gearbox, recently seen in the Lamborghini Revuelto. This hybrid powertrain is engineered to deliver an impressive output of nearly 900 hp.
Its 4L twin-turbo V8 boasts a specific power of 200 hp/liter, delivering 800 hp between 9,000 and 9,750 rpm and can reach a maximum engine speed of 10,000 rpm — figures typically reserved for racing engines. Additionally, the engine generates a maximum torque of 540 lb-ft between 4,000 and 7,000 rpm, promising an exhilarating driving experience.
================
Looks like it is either a new engine not based on the EA825 or a significant re-work. Apparently no AVL cam actuators and changed HPFP position vs EA825. HPFPs look gear-driven vs lobe-follower which makes sense given the ~10k rpm max engine speed. It will be interesting to see a full technical write-up on this.
Going further on the new product topic, it seems reasonable Lamborghini would introduce a grand tourer. With two V8 engines to choose from, project 634 and the EA825, and based on a heavily reworked MSB platform, a front- or front-mid engined 2+2 would be a natural addition to the product lineup.
