The Audi RS4 quattro is a high performance version of certain vehicles in the Audi A4 range of cars and is classified as a compact executive car. The RS4 is manufactured by Audi’s high-performance private subsidiary, Quattro GmbH, but only a limited number of units were ever made. This vehicle is just above the Audi S4 in terms of speed and is a sports-focused model that is based on the A4’s “B” platform. In 2012, the RS4 made a comeback, but only as the Avant model which was based on the Audi A4 Avant.
The B5 version of the RS4 was originally produced as just a 5-door five-seat Avant, which is Audi’s name for the estate car/station wagon. The second version of this vehicle was released as a 4-door 5-seat sedan/saloon with the Avant coming out shortly after. There was also a 2-door four-seat Cabriolet version of this vehicle which was subsequently added to the range of these vehicles. The internal combustion engines that all of these vehicles use are front-mounted and longitudinally oriented. The transmission that these vehicles use is mounted at the rear part of the engine in a similar longitudinal orientation.
The initials “RS” that this vehicle uses come from the German: RennSport, which means “racing sport” and was marketed as Audi’s highest trim level, just above the “S” model of the regular model lineup. Similar to all of the other RS cars, the RS 4 uses some of the most recent and advanced technology that Audi has to offer, and is often called a “halo vehicle”. This vehicle is only available with Audi’s Torsen-based Quattro permanent 4-wheel drive system. Some of the RS4’s primary competitors include the BMW M3 as well as the Lexus IS-F and the Cadillac CTS-V.
The B5 Audi RS 4 Avant Quattro was introduced to the public in late 1999 with sales starting in 2000, succeeding Audi RS2 Avant. Similar to the RS2, this vehicle was initially made available only as an Avant and was built on an existing platform, specifically the Volkswagen Group B5 platform, which was also used for the A4 and the S4. This car was made available in most parts of Europe as well as certain countries in Asia and Latin America. While it is true that the Audi RS 4 is related to the Audi B5 S4, its outer body panels were significantly altered with wider front and rear wheel arches in order to make room for the wider axle track.
The engine that the B5 uses originally came from the 2.7 liter V6 ‘biturbo’ which was used in the B5 S4 as well. This engine displaced 2,671 cubic centimeters and had a total of 5 valves for every cylinder. This engine was manufactured in the UK by Cosworth Technology, which is known called MAHLE Powertrain, and featured an enlarged intake as well as smaller exhaust ports. There were some modifications done to this engine which increased its output from 195 kilowatts to 400 netwon meters of torque.
The B7 RS 4 was produced from 2006 to 2008, though only the 2007 and 2008 models were ever sold in the U.S. This vehicle was first unveiled to the public in February of 2005 at Audi’s ‘quattro Night’ celebration in Ingoldstadt, Germany, where its headquarters are located. The overall bodywork and styling of the B7 is a great departure from anything it has done in the past and was available only as a four-door 5-seat saloon/sedan when it was first released. This vehicle received great reviews from critics and was a hit with consumers as well, making it one of Audi’s more successful models to date.
