The Audacious IV combines Audi Quattro-inspired styling with B7 RS4 mechanicals, a six-speed manual gearbox and the option of a V8 engineered to reach 10,000rpm.
British builder Audacious Automotive plans just 50 examples worldwide, with commissions starting at £350,000 before source vehicles, individual specification, registration and applicable taxes. This is an independent project, with no affiliation to Audi.
Rather than recreating the original Quattro’s five-cylinder powertrain, the IV uses the RS4’s 4.2-litre V8 and Torsen all-wheel-drive architecture. Its engineering foundation also incorporates the donor model’s lower structure, suspension geometry, steering and braking systems.
Four engine programmes are advertised. Stage One adds a supercharger for a claimed 600bhp, while Stage Two raises that to 750bhp with further internal, cooling, fuelling and driveline development.
Separate naturally aspirated and supercharged programmes offer the headline 10,000rpm engine speed. Audacious has not published individual power figures for those two specifications on its main product page.
Two approaches to the Quattro-inspired body
Buyers can choose hand-formed metal bodywork incorporating an original Quattro’s upper structure, roof and glazing. Alternatively, a carbon-fibre version uses a newly made upper body and glazing, removing the need for an original Quattro source vehicle.
Both retain the RS4-based engineering foundation. Choosing carbon fibre therefore avoids using a classic Quattro shell; it does not mean the car has no donor-derived components.
Audacious advertises a sub-3.4-second 0–60mph time and a 200mph top speed. These remain manufacturer claims, without a configuration-specific performance breakdown on the product page.
Autocar reports target weights of 1,400–1,450kg for the metal-bodied cars and approximately 1,200kg for carbon versions. Those are development targets rather than confirmed production weights.
Built around each buyer
Personalisation extends beyond paint and upholstery. Customers can work with founder and designer Mac Zaglewski on materials, instrumentation, interior layout, suspension character and mechanical specification.
Commissions are being accepted, with prospective buyers able to visit the company’s studio near Edinburgh by appointment. The advertised £350,000 starting figure excludes several substantial costs, so the final price will depend on the source vehicles and agreed specification.
