APR’s Engineering Teams are pleased to present our first iteration of the Audi 4.2l V8 FSI supercharger application. Producing over 570hp and 510 ft-lbs of torque, APR’s RS4 Stage III propels one of Audi’s most prestigious performance vehicles to new levels of acceleration and performance.

Applying forced induction to a normally aspirated production engine is no simple task and APR’s Engineering Teams understand that new innovations, processes and components must be incorporated into the design to insure OEM reliability and drivability while producing incredible performance results. Within APR’s Stage III, you will find more components and higher quality parts at every comparison than with any of the competing products currently available. The goal of APR’s design was not merely fitment and operation but consideration of the long term effects of such a dramatic power increase and the overall reliability of the vehicle. Extra steps must be taken to insure Performance Without Compromise.

Not only will RS4’s equipped with APR’s Stage III produce blistering increases in wide open throttle acceleration, daily driving is greatly improved with increased torque and horsepower available in even the lowest rpm’s of the power band. Less downshifting for passing and greater rates of acceleration at all points result in a driving characteristic of pure enjoyment in all situations. Both Drag Racing and Road Racing demands are taken into consideration during the design and calibration process in order to provide a well rounded solution for all enthusiasts.

APR’s Calibration Team has spent countless hours in a wide range of environmental conditions to develop an ecu calibration that utilizes APR’s Stage III hardware in a safe and powerful manner. Hot weather, cold weather and everything in between has been considered with multiple prototypes operating in extreme conditions for long periods of time prior to the Stage III release.

APR’s patented EMCS solution allows Stage III owner’s to use their factory cruise control to select the best calibration for their current driving situation. Two different pump gas calibrations and a race gas calibration allow the end user to select different power levels for different uses and enjoyment at the end user’s determination.

APR’s Calibration Team has also developed calibrations specific to the fuel qualities in all areas of the world. Prototyping, testing, development and production is a worldwide exercise with APR partners all over the globe. Expect similar performance, reliability and drivability whether you reside in or travel to North America, Europe, Asia or South America, Africa and Oceania. APR’s Calibration Team has developed specific calibrations for your climate.

APR’s Patented EMCS Technology

Featuring APR’s Patented EMCS program switching functionality and DirectPort Programming, APR’s Engine Management Calibration for this conversion package allows for a range of Octane and situation specific calibrations to be installed simultaneously on your vehicle’s ECU. These programs and features are able to be cycled through via your existing factory cruise control and activated in less than 20 seconds. You will be able to choose 1 to 4 Programs listed below. You will also be able to add APR Security Lockout, APR Fault Code Erase and APR Anti-Theft features.

APR began supercharger development of the Audi 4.2L V8 engine in 2004. After several design reconsiderations and the availability of new technologies, APR is confident that the each component included in the Stage III system is of the highest quality and is perfectly matched to the 4.2L application. All components necessary for a full installation and enjoyment of use including the expertly recalibrated engine management software are included with the exception of an upgraded clutch for the transmission. APR’s Engineering Team developed and selected the best components possible, not a component that merely fits the bill but exceeds expectations in order to produce unsurpassed quality.

AUBURN HILLS, Mich. – Audi will be the official automotive sponsor of Art Chicago, America’s longest-running international modern and contemporary art fair. During Art Chicago, Audi will introduce the Audi RS 4 Art car created by Brazilian-born Pop artist Romero Britto.

Involvement in contemporary art and design has long been a component of Audi’s corporate culture – partnering with some of the world’s most renown shows – among them Design Miami/ 2006, the Armory Show 2007 in New York and latest Art Chicago. “Being involved in cutting-edge art events is a natural fit for Audi as a progressive premium brand” says Johan de Nysschen, Executive Vice President in charge of Audi of America. “Art Chicago is another opportunity for us to demonstrate our commitment to design by exhibiting the RS 4 Art Car which is a piece of art o­n its own.”

Chris Kennedy, President of the Merchandise Mart Properties, Inc., adds: “We are very proud to have Audi come o­n board as exclusive automotive sponsor of Art Chicago. Audi has long been recognized a trendsetter in automotive design and dedicated to exploring innovative ideas and make visions come true which reflects the spirit of Art Chicago.”

The Audi RS 4 is the ultimate in high-performance luxury, taking performance and design to the next level with its compelling and distinctive presence, 420-hp V8 engine and quattro® all-wheel drive.

Britto, a modern day pop culture icon, has been a fixture o­n the international art scene since 1989 when he was commissioned by Absolut Vodka, along with Keith Haring and Andy Warhol to design a bottle label for the company. Following o­n the heels of Absolut, Britto’s whimsical Pop Art is consistently commissioned for corporate collections from around the world.

The Audi RS 4 art car is his most recent project. Being a car enthusiast, art cars have always been among Britto’s favorite projects. “For the Audi RS 4, I wanted to create something that would combine sophistication, dynamism and fun o­n o­ne hand, but also include the aspect of a future generation o­n the other – as Audi is an innovative and leading brand”, Britto says. “This is why I came to choose the portrait of a woman as it incorporates all these attributes.”

Following its debut at the exclusive Art Chicago Opening Party, the Audi RS4 Art Car will embark o­n a tour of some of the world’s most captivating cities between New York and Mexico D. F. Super-bowl winning Quarterback Tom Brady will be the first to drive the Audi RS 4 Art car. The ‘Audi RS 4 Art Car Collectors’ Tour’ will culminate in South Beach, Miami, where it will be the centerpiece of a Live Auction benefiting Best Buddies International, a non-profit organization founded by Anthony Kennedy Shriver.

Romero Britto is a longtime supporter and friend of Best Buddies. He most recently donated his image ‘Best Buddies’ to the Best Buddies Artist Collection featured at Art Chicago.
