Fastest and most powerful V12 in Lamborghini history

Lamborghini reveals Fenomeno in 2025

In August 2025, Lamborghini unveiled the Fenomeno at Monterey Car Week to celebrate 20 years of its Centro Stile design center. The supercar was announced as the most powerful Lamborghini V12 ever built. It carries a naturally aspirated 6.5-liter V12 producing 835 horsepower at 9,250 rpm.

Alongside three electric motors producing 245 horsepower, the combined output reaches 1,080 horsepower. Lamborghini limited production to 29 customer cars plus one museum car, each priced at around $3.5 million.

Fenomeno sets record performance figures

The Fenomeno achieves a weight-to-power ratio of 1.64 kilograms per horsepower, the best figure in Lamborghini’s history. This ratio contributes to its extreme acceleration and speed capabilities.

It sprints 0–100 km/h in 2.4 seconds and 0–200 km/h in 6.7 seconds. Its top speed exceeds 217 miles per hour, placing it among the fastest cars Lamborghini has ever produced. These numbers mark the strongest performance benchmarks set by the brand.

Fenomeno’s carbon fiber body and cooling

From performance, the Fenomeno’s design uses all carbon fiber panels, creating what Lamborghini calls a “design manifesto.” Its longtail proportions and vertical Y-shaped taillights provide a new visual identity.

A new S-Duct and active aero boost downforce and efficiency, while revised side-intake airflow through the doors improves cooling efficiency by over 30% vs. earlier V12s.The design borrows an extended tail profile from the track-only Essenza SCV12 but remains entirely street legal. A large hexagonal exhaust outlet completes its exterior character.

Fenomeno applies race car technologies

Racing knowledge from Lamborghini’s LMDh program was used in the Fenomeno. The braking system uses CCM-R Plus carbon-ceramic discs with long-fiber carbon matrix material. A new 6D sensor monitors acceleration and angular velocity across three axes in real time.

Adjustable racing shocks replace adaptive dampers from the Revuelto. Custom Bridgestone Potenza Sport run-flat tires are fitted, with 21-inch wheels at the front and 22-inch at the rear, secured with single-nut hubs.

Fenomeno’s futuristic cabin details

The Fenomeno’s interior reflects Lamborghini’s “Feel like a pilot” idea. Three digital displays manage functions, while carbon fiber dominates surfaces. Bucket seats are designed specifically for the model. Even the air vents are made using 3D-printed carbon fiber.

Lamborghini’s Ad Personam program allows more than 400 exterior colors and nearly unlimited interior combinations. Deliveries for the 29 customer cars are expected to begin in late 2025, with the 30th example held in Lamborghini’s museum.

Lamborghini begins with V12 in 1963

The story of Lamborghini’s V12 starts before the Fenomeno, with the 350 GT shown in 1963. Its engine was designed by Giotto Bizzarrini after he left Ferrari. The 3.5-liter quad-cam V12 produced 266 horsepower at 7,000 rpm and 239 pound-feet of torque at 4,000 rpm.

Prototype versions of the engine could reach 365 horsepower at 9,000 rpm. Using six Weber carburetors and a short-stroke design gave the V12 a free-revving character.

V12 evolves in Miura from 1966 to 1973

In 1966, Lamborghini enlarged the V12 to 3.9 liters for the 400 GT and Miura. The Miura became the fastest road car of its time and is regarded as the first supercar. Between 1966 and 1973, Lamborghini built 764 Miuras.

Power started at 345 horsepower in the early cars and rose to 380 in the Miura SV. The engine was moved behind the driver for better weight distribution, setting a mid-engine formula for Lamborghini supercars.

Countach enlarges engines into 1980s

The Countach carried the V12 into the 1970s and 1980s. Early cars used the 3.9-liter version, but by 1982, the LP500S model featured a 4.8-liter engine producing 375 horsepower. In 1985, Lamborghini introduced the LP500 Quattrovalvole with a 5.2-liter V12.

It used four valves per cylinder and Bosch K-Jetronic injection in U.S. models. European cars retained carburetors until the Diablo era. Late versions of the 5.2-liter engine produced about 449 horsepower. The same engine was also used in the LM002 SUV.

Diablo introduces 5.7 liter V12 in 1990

The Diablo debuted in 1990 with a 5.7-liter V12 producing 485 horsepower. It was the first Lamborghini V12 model to use a four-wheel-drive system. Later Diablo models included the GT and VT with a larger 6.0-liter version of the V12.

These cars represented the highest development of the Countach-era design before the introduction of the Murciélago in 2001, closing another step in Lamborghini’s engine growth.

Murciélago ends Bizzarrini V12 in 2010

The Murciélago was introduced in 2001 with a 6.2-liter V12 producing 572 horsepower. This engine featured a dry-sump oil system to sit lower in the chassis. From 2006, the Murciélago LP models used a 6.5-liter version.

The final Murciélago LP 670-4 Super Veloce produced 661 horsepower and was built until 2010. It became the last Lamborghini to use the Bizzarrini-based V12 before the Aventador introduced a new engine design in 2011.

Aventador introduces L539 V12 in 2011

In 2011, Lamborghini launched the Aventador with an all-new 6.5-liter V12 known as the L539. It kept the 60-degree cylinder banks but was shorter and lighter than the Murciélago’s V12.

The first Aventador produced 700 horsepower and 509 pound-feet of torque. Later versions like the Aventador SVJ produced 759 horsepower. The final version, the Aventador LP780-4 Ultimae, released in 2022, produced 769 horsepower, the most in any naturally aspirated Aventador.

Hybrid V12s appear in Sian and Countach

In 2019, Lamborghini revealed the Sián as its first hybrid V12. It integrated a 6.5-liter V12 with a 48-volt electric motor into the gearbox. The motor added 34 horsepower, creating a total output of 785 horsepower.

In 2021, Lamborghini released the Countach LPI 800-4 with the same system. Both cars showed Lamborghini testing electrification using V12 engines in limited production models.

Revuelto begins third generation in 2023

The Lamborghini Revuelto debuted in 2023 with the L545 V12, marking the start of the brand’s third V12 generation. The new engine was rotated 180 degrees compared to the Aventador’s design.

It was also lighter and more powerful than previous engines, with revised air intakes and distribution. The Revuelto used a lithium-ion battery in the central tunnel to power its three electric motors. In 2024, the Lamborghini Temerario became the second High-Performance Electrified Vehicle.

Ferruccio Lamborghini challenges Ferrari

Ferruccio Lamborghini, born under Taurus, began making tractors after World War II. His success allowed him to buy cars like Ferraris, which often needed repairs. After a dispute with Enzo Ferrari about these issues, he built his own sports cars.

In 1963, Lamborghini presented the 350 GT, powered by the Bizzarrini V12. This car marked the beginning of Lamborghini’s rivalry with Ferrari and its entry into the world of high-performance automobiles.

Iconic Miura and Countach shock crowds

In 1966, the Miura debuted at the Geneva Motor Show. Designed by Marcello Gandini of Bertone, it stunned audiences with futuristic styling and became the world’s first supercar.

In 1974, Lamborghini introduced the Countach, which Gandini designed. Its scissor doors and sharp lines became symbols of the brand. The Countach remained in production for over a decade and became Lamborghini’s most recognizable model.

A new model called the first true supercar was built to handle daily driving without compromise. See details in the first supercar you can truly daily drive.

Audi takes control and expands lineup

After financial struggles, Audi purchased Lamborghini in 1998 for $111 million, as per Business Insider. Under Audi, Lamborghini released the Murciélago in 2001, the Gallardo in 2004, and the Aventador in 2011.

The Gallardo became the brand’s best-selling model, while the Aventador introduced the new V12 generation. By 2018, Lamborghini also launched the Urus SUV. With the Revuelto in 2023 and the Fenomeno in 2025, Lamborghini now builds its fastest and most powerful V12s ever.

Audi’s big push into China took a turn when the country’s policies shifted against the brand. Read more in Audi’s China expansion backfired when China changed Audi.
