The &#8220;RR&#8221; designation stood for &#8220;Rallye Racing,&#8221; signaling the car&#8217;s competition intent.

Wider wheel arches, a deep front spoiler, and adjustable rear wing distinguished the RR from standard Quattros. Audi needed 200 examples for Group A homologation.

Throughout the 1980s, the Quattro dominated the World Rally Championship, winning multiple manufacturers&#8217; and drivers&#8217; titles. By the late 1980s, the Ur-Quattro had evolved significantly, but competition regulations demanded continued homologation updates.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Development of the RR began in 1988 under Audi Sport GmbH. The brief was straightforward: create the ultimate road-going Quattro that satisfied Group A homologation requirements while showcasing the platform&#8217;s final evolution. This would be the last homologation special based on the original Quattro.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Engineers focused on extracting maximum performance while improving aerodynamics and chassis dynamics. The turbocharged inline five received modifications increasing output to 220 horsepower. Suspension geometry was revised with wider tracks and lowered ride height. Aerodynamic enhancements included a deeper front spoiler, wider wheel arches, and an adjustable rear wing. The Quattro RR debuted at Frankfurt in September 1989, with production beginning immediately at Audi&#8217;s Ingolstadt facility.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Design and Engineering<\/span><\/h2>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-895430\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-4-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The RR was based on the standard Quattro&#8217;s steel monocoque with a 2,524mm wheelbase, reinforced to handle increased power and improved suspension geometry. Front suspension used MacPherson struts with lower A-arms, revised with stiffer springs, uprated Bilstein gas-pressure dampers, and modified geometry. The rear employed a similar arrangement with increased negative camber for improved cornering grip. Ride height dropped 20mm compared to standard Quattros.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Braking was by cross-drilled and vented discs measuring 280mm front and 245mm rear with four-piston calipers. ABS remained absent as rally regulations prohibited it. Power steering was standard with a quick ratio.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The engine was Audi&#8217;s turbocharged inline five, code-named WR. Displacing 2,226cc with an 81mm bore and 86.4mm stroke, this all-aluminum engine featured a SOHC head with two valves per cylinder. A KKK K26 turbocharger provided forced induction, with compressed air cooled by an air-to-air intercooler.<\/span><\/p>\n<figure id=\"attachment_895432\" aria-describedby=\"caption-attachment-895432\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-895432\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-5-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-895432\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">Bosch Motronic engine management controlled fuel injection and ignition timing.

The bonnet featured a prominent bulge to clear the intake manifold.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Side profile was dominated by those enormous fender flares, bonded and riveted to the body structure. Quattro RR badges appeared on the front fenders. At the rear, an adjustable rear wing sat atop the trunk lid on substantial aluminum supports, providing genuine downforce. Body panels were steel, hand-fitted to accommodate the wider tracks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Standard wheels were 8&#215;15-inch BBS cross-spoke alloy units wearing 215\/50 VR15 Pirelli P700-Z tires, the widest rubber ever fitted to a production Quattro.

However, by the late 1980s, Audi&#8217;s factory motorsport focus had already shifted away from the legendary coupe. Following the abrupt end of Group B in 1986, the company pivoted to the new Group A regulations, which demanded a minimum production run of 5,000 units to achieve homologation. Because the hand-assembled Ur-Quattro could not meet these high volume requirements, Audi selected the mass-production Audi 200 Quattro sedan as its new rally weapon. Powered by a rugged, turbocharged five-cylinder engine, the larger 200 Quattro served as Audi&#8217;s primary stage rally platform for the late 1980s, securing a historic victory at the 1987 Safari Rally.<\/p>\n<h2><span style=\"font-weight: 400;\">Production and Legacy<\/span><\/h2>\n<figure id=\"attachment_895431\" aria-describedby=\"caption-attachment-895431\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-895431\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/05\/1990-audi-quattro-20v-12-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-895431\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p data-path-to-node=\"0\">Audi hand-assembled around 600 examples of the 20-valve Ur-Quattro with the &#8220;RR&#8221; engine code at Ingolstadt between late 1989 and early 1991.
