Rather than developing the engine exclusively around existing Audi automotive technology, engineers looked elsewhere within the Volkswagen Group for inspiration: Ducati.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key design parameters and components were based on the Ducati 1196R and its Testastretta engine, most notably its use of desmodromic valve control. The resulting 4.8-liter V8 was intended to combine Audi Sport engineering with concepts developed for one of Ducati&#8217;s highest-performance motorcycle engines.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2000\" height=\"1250\" src=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388.jpg\" alt=\"\" class=\"wp-image-8687\" srcset=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388.jpg 2000w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-300x188.jpg 300w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-1024x640.jpg 1024w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-768x480.jpg 768w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-1536x960.jpg 1536w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-770x481.jpg 770w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-388-1400x875.jpg 1400w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">DESMODROMIC V8<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SHDZ stands for&nbsp;<em>Desmodromische Ventilsteuerung<\/em>, or desmodromic valve control, the defining feature of the prototype&#8217;s engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a conventional valvetrain in which camshafts mechanically open the valves and springs close them, a desmodromic system mechanically controls both opening and closing. The technology has been particularly associated with Ducati and allows precise valve control at extremely high engine speeds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Audi&#8217;s planned 90-degree V8 displaced 4,793.6 cc and employed an extremely short-stroke architecture with a large cylinder bore. Four desmodromically controlled valves were fitted per cylinder and operated by two variable overhead camshafts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result was a targeted 700 hp at 10,500 rpm, with maximum torque of 580 Nm arriving at 6,750 rpm.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2000\" height=\"1250\" src=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383.jpg\" alt=\"\" class=\"wp-image-8682\" srcset=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383.jpg 2000w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-300x188.jpg 300w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-1024x640.jpg 1024w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-768x480.jpg 768w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-1536x960.jpg 1536w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-770x481.jpg 770w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-383-1400x875.jpg 1400w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">DUCATI CONNECTION<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The SHDZ represents a particularly unusual piece of engineering cross-pollination between Audi and Ducati following Audi&#8217;s acquisition of the Italian motorcycle manufacturer in 2012.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Audi engineers based key design parameters for the experimental V8 on components from the Ducati 1196R. Rather than simply installing or combining existing motorcycle engines, however, Audi developed an entirely new 90-degree V8 incorporating Ducati-derived desmodromic concepts into an automotive powerplant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A gear cascade positioned at the rear of the engine drove the camshafts, while a continuous PTO shaft powered ancillary components mounted at the front.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other features included dry-sump lubrication, variable intake manifolds and a bespoke firing order developed by Audi Sport.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result was effectively an Audi-designed, Ducati-influenced 4.8-liter V8 capable of operating at an engine speed more commonly associated with motorcycles and racing engines than road-going V8s.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2000\" height=\"1250\" src=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386.jpg\" alt=\"\" class=\"wp-image-8686\" srcset=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386.jpg 2000w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-300x188.jpg 300w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-1024x640.jpg 1024w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-768x480.jpg 768w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-1536x960.jpg 1536w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-770x481.jpg 770w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-386-1400x875.jpg 1400w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">R8 DEVELOPMENT<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The engine was only one component of the SHDZ program. Audi modified the R8 extensively around the concept of creating a road-legal race car.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Air filters, the cooling system, exhaust manifold and catalytic-converter modules and the complete exhaust system were adapted specifically for the new engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Dynamite Red bodywork incorporated carbon fiber and aluminum components, while revised spoilers, front splitter elements and diffusers addressed the aerodynamic requirements of the higher-performance specification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Audi also altered the final-drive ratio and pursued significant reductions in unsprung mass through specially developed magnesium wheels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The front wheels weighed just 6.5 kg (14.3 lb) each. Despite measuring 20 inches, the rear wheels weighed between just 7.7 and 7.9 kg (17.0\u201317.4 lb), depending on design.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">PERFORMANCE<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Audi targeted performance well beyond that of the contemporary production R8.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 4.8-liter V8 was specified at 700 hp at 10,500 rpm and 580 Nm at 6,750 rpm. Power was transmitted through a seven-speed tiptronic transmission and permanent quattro all-wheel drive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Audi projected acceleration from 0\u2013100 km\/h (62 mph) in 2.8 seconds, while 200 km\/h (124 mph) would arrive in just 8.75 seconds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The combination is particularly notable because Audi wasn&#8217;t relying on turbocharging or hybrid assistance to achieve those figures. Instead, the SHDZ concept pursued power through displacement, airflow and exceptionally high engine speed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"2000\" height=\"1250\" src=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389.jpg\" alt=\"\" class=\"wp-image-8688\" srcset=\"https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389.jpg 2000w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-300x188.jpg 300w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-1024x640.jpg 1024w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-768x480.jpg 768w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-1536x960.jpg 1536w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-770x481.jpg 770w, https:\/\/ooooiykyk.com\/audiarchives\/wp-content\/uploads\/sites\/2\/2014\/08\/2014-Audi-R8-SHDZ-prototype-389-1400x875.jpg 1400w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SHARED DNA<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The R8 SHDZ represents one of the more unusual engineering connections within the Volkswagen Group.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Audi acquired Ducati through Lamborghini in 2012, placing the Italian motorcycle manufacturer within Audi&#8217;s corporate structure. Just two years later, the SHDZ project explored how one of Ducati&#8217;s defining technologies might be translated from a high-performance motorcycle engine into an Audi road-car application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ducati&#8217;s influence was fundamental to the engine concept, but the resulting V8 was not simply a pair of motorcycle engines joined together. Audi Sport developed a purpose-built 4.8-liter automotive V8 around the desmodromic principle, adding its own firing order, intake system, lubrication architecture and supporting systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It represents an intriguing reversal of the more familiar Shared DNA formula. Rather than Audi technology finding its way into another manufacturer&#8217;s vehicle, technology from another Audi Group marque was being used to explore what an extreme Audi R8 might become.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">KNOWN HISTORY<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2012<\/strong>&nbsp;\u2013 Audi acquires Ducati through Lamborghini, bringing the Italian motorcycle manufacturer into the Audi Group.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2014<\/strong>&nbsp;\u2013 Audi develops the R8 SHDZ as an experimental road-legal race-car concept based around an entirely new high-revving V8.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2014<\/strong>&nbsp;\u2013 Key engine design parameters are derived from components used by the Ducati 1196R, with Audi developing a 4,793.6 cc 90-degree V8 employing four desmodromically controlled valves per cylinder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2014<\/strong>&nbsp;\u2013 The experimental engine targets 515 kW (700 hp) at 10,500 rpm and 580 Nm at 6,750 rpm.

The SHDZ wasn&#8217;t simply an R8 with Ducati branding or a conceptual exercise in corporate synergy. Engineers actually attempted to translate Ducati&#8217;s desmodromic valvetrain philosophy into an entirely new Audi V8.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, Audi decided not to proceed with the project. Further rumors suggest the lack of low-end torque played a part in the decision-making in this case. Other R8 test mules featuring turbocharged V6 and even I5 configurations were also rejected for the same reason. That this car exists though at such a refined level of development &#8211; a bespoke engine rather than another unit already in production fitted to the R8 suggests the SHDZ drivetrain and the car meant to go with it were considerably far along in process by the time the decision not to produce was finalized.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Had it reached production, the R8 SHDZ would have been one of the most unusual engines ever fitted to a road-going Audi. Instead, it remains a fascinating technical dead end \u2014 and one of the most extreme R8 prototypes Audi ever developed.<\/p>\n\n\n\n<hr class=\"wp-block-separator
