British Company Revives the Audi Quattro With a 750 HP V8 Engine and Just 50 Units Planned

The Audi Quattro is preparing to return to the world of sports cars with a modern interpretation and exceptional performance specifications. This time, however, the project comes from a British company under the name Audacious IV, developed by Audacious Automotive and inspired by the legendary Audi Quattro, a model closely associated with the history of rally racing.

The new project combines the Quattro-inspired classic design with the engineering of the Audi RS4 B7, replacing the iconic five-cylinder engine of the original Quattro with a 4.2-liter V8 engine available in several configurations, with output reaching up to 750 horsepower in its most powerful version.

The British company plans to produce just 50 cars worldwide, with the first customer deliveries scheduled to begin in late 2027.

Audacious IV: Reviving the Audi Quattro With a Modern Approach

The Audacious IV is not a new production model from Audi. Instead, it is an independent project that reimagines the Quattro by combining the appearance of the classic rally car with modern mechanical engineering derived from the Audi RS4 B7, which was produced between 2006 and 2008.

The car uses the RS4's underlying engineering platform, including its floor structure, suspension geometry, drivetrain, braking system, steering, and electrical and control systems. Several components have been extensively re-engineered to accommodate the new design and targeted performance levels.

The exterior design draws inspiration from the original Audi Quattro's short-wheelbase proportions, with styling elements influenced by Group B rally cars, including wide fenders and a prominent rear spoiler. The result combines a classic identity with a modern performance-oriented appearance.

Notably, the vehicle will not carry original Audi badges. Instead, it will feature Audacious branding, emphasizing that it is an independent project rather than an official model from the German automaker.

4.2-Liter V8 Engine Producing Up to 750 HP

The Audacious IV replaces the five-cylinder engine that made the original Quattro famous with a 4.2-liter V8 derived from the Audi RS4 B7. The engine receives extensive mechanical modifications and is available in four different performance configurations.

The range starts with a supercharged engine producing 600 horsepower in the Stage One configuration. Output increases to 750 horsepower in Stage Two, which includes upgraded internal engine components, cooling and fuel delivery systems, and an improved supercharger.

The other two configurations focus on raising the engine's operating limit to 10,000 rpm. One uses natural aspiration without a supercharger, while the other employs forced induction, with specialized engineering and modifications designed to withstand the higher engine speeds.

The company has not yet announced final power and torque figures for the two configurations designed to reach 10,000 rpm. Therefore, the 750 hp figure should not automatically be associated with every version capable of reaching that engine speed.

Six-Speed Manual Transmission, All-Wheel Drive, and a Top Speed of 322 km/h

Despite its modern engineering and performance upgrades, the Audacious IV retains a traditional driving experience through a six-speed manual transmission sourced from the Audi RS4, paired with an all-wheel-drive system using Torsen technology to distribute power between the axles.

According to the company, the car is capable of accelerating from 0 to 60 mph (approximately 96 km/h) in less than 3.4 seconds, with a targeted top speed of 200 mph, equivalent to approximately 322 km/h.

These figures represent the company's announced performance targets rather than results from independent testing of completed production vehicles.

Carbon-Fiber Body or Reworked Original Quattro Body

The company offers two main options for the vehicle's body structure, allowing customers to choose the configuration that best suits their preferences.

The first option retains the original upper body structure of the UR Quattro, including the roof and windows, while incorporating newly developed steel and aluminum components around the underlying RS4 engineering platform.

The second option uses a newly developed upper body made from carbon fiber, with specially designed glass. This configuration does not require an original Quattro donor car.

The carbon-fiber version targets a weight of approximately 1,200 kg, compared with around 1,400–1,450 kg for versions retaining the original Quattro body structure, according to published industry reports.

Reducing weight is a key part of the project, as it directly affects the car's responsiveness, handling, and ability to make use of the engine's substantial power output.

Interior Combines Classic Design With RS4 Components

The modifications extend beyond the body and engine. The interior has been redesigned to recall the straightforward, mechanical character of the original Quattro, with a custom dashboard, instruments, and control switches.

The company has removed the original digital equipment from the RS4 while retaining selected components, including its well-known Wingback sport seats, which feature electric adjustment.

Audacious Automotive also offers extensive customization options, allowing customers to choose exterior colors, interior materials, and finishes, as well as specify suspension settings and mechanical equipment according to their intended use.

The company says every Audacious IV will be individually configured, making each car a personalized project for its owner.

Just 50 Cars Planned, With Prices Starting at Approximately $470,000

Audacious Automotive plans to produce only 50 examples of the Audacious IV at its facilities in Edinburgh, Scotland, with reservations and individual customization available to interested customers.

Prices start at approximately $470,000, excluding VAT, donor-car costs, transportation, registration, and additional bespoke equipment.

The first customer deliveries are scheduled for late 2027. The company indicates that the process of building a car, from agreeing on its specifications to final delivery, may take around three years.

The Audacious IV offers a different approach to reviving classic sports cars, retaining the design identity of one of rally racing's most iconic models while introducing modern mechanical engineering and performance options of up to 750 horsepower, alongside specialized engine configurations targeting 10,000 rpm. Production will be limited to just 50 cars worldwide.
