The Lamborghini 634 – the code name for the successor to the Huracán that will join the High Performance Electrified Vehicle (HPEV) line-up – will be equipped with a twin-turbo V8 engine, combined with a hybrid system incorporating three electric motors and the eight-speed dual-clutch gearbox that recently debuted on the Lamborghini Revuelto, optimized for the new model.
The all-new engine is a clean-sheet design from Sant’Agata Bolognese, with the objective of delivering performance and driving emotion that surpass those of the current Huracán range. The twin-turbo V8 combines the high linearity of progression that made the Lamborghini V10 famous with the high power and specific torque of a new-generation turbocharged engine.
The twin-turbo V8 features displacement of 4.0 liters and an exceptional specific power of 200 CV/liter. The maximum power delivered by the ICE will be 800 CV between 9,000 and 9,750 rpm, reaching a maximum engine speed of 10,000 rpm: a figure normally reserved for racing engines and making the new V8 unique in the landscape of road-going super sports cars. It is also unique in terms of the maximum torque delivery of 730 Nm between 4,000 and 7,000 rpm, with an exhilarating progression similar to that of a racing engine, thanks to the perfect integration of the electric unit with the combustion engine.
The rear electric system designed and developed for the new V8 is positioned between the combustion engine and the dual-clutch gearbox and includes the inverter as well as the axial electric unit. It is capable of generating high torque and power values, with a maximum of 300 Nm and 110 kW at 3,500 rpm, while still keeping compact dimensions and low weight.
Another crucial element of the design process was to define the sound, to give the new powerplant a unique and distinctive character and deliver the driver an unparalleled driving experience. The characteristics of the new V8 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.

00:00 Today is a very special day for me to present you the first details of the successor of our very successful Huracan with the internal code Lamborghini 634.
00:12 And we start with the heart of the car, the engine that will push the bar for engineering masterpieces to another level.
00:21 Our all-new V8 biturbo engine is a clean sheet design from our team inside Agra Bolognese with the objective of delivering on one hand performance as well as driving emotions.
00:33 And I can guarantee to you this twin turbo V8 combines this celebrated Lamborghini V10 emotional progression through the linear torque curve on one hand with the high power and specific torque of a state-of-the-art new generation turbo engine.
00:50 But let's take a look at some technical data of the brand new V8.
00:55 First of all, it's a 4-liter engine with an exceptional specific power output of 200 CV per liter.
01:03 And the maximum power output is 800 CV.
01:07 The maximum torque of 730 Nm is delivered in a wide range of revs.
01:14 With an absolute exciting torque curve similar to that is usually known in race engines.
01:21 And the maximum rev limit is 10,000 rpm.
01:26 And this for a biturbo engine that is really outstanding in the automotive landscape.
01:33 But let's take a look a little bit more on the mechanical side of the engine.
01:37 Let's take a look at some typical characteristics.
01:41 First of all, starting with a flat plane crankshaft.
01:44 This is typical for high performance engines and generates a characteristic sound.
01:49 Secondly, the engine is equipped with titanium conrods.
01:53 These are on one hand reducing the rotational masses and provide on the other hand extraordinary material properties.
02:00 Furthermore, the engine is equipped with a central direct injection system with a pressure up to 350 bars.
02:08 To rev up to 10,000 rpm it's fundamental to have a very stiff valve train.
02:15 In this engine we have chosen a finger follower valve train like in motorsports.
02:19 With high stiffness, high precision, maximum revs.
02:23 The turbochargers are placed inside the V.
02:27 It's a so-called hot V engine that has several advantages regarding the compactness
02:33 and as well is improving the thermo as well as the fluid dynamics.
02:38 Furthermore, the engine is equipped with a dry sump system that is safeguarding the engine lubrication
02:44 also at very high lateral forces and this is mandatory if we speak about the engine for a real super sports car.
02:53 And this masterpiece we combined with an additional electric motor in P1 position.
02:59 And this is also a very special electric motor because it's an actual flux machine that is oil cooled,
03:05 has a peak power of 110 kW and a maximum torque of 300 Nm.
03:10 This seamless integration between the combustion engine on one hand and the electric motor on the other hand
03:16 results in an outstanding transient behavior as well as an instant response of the drive train.
03:23 So you can be very excited. Stay tuned.
