The 1992 season opened at Zolder with a grid unrecognizable from the one that closed at Hockenheim eight months prior. The new Evo-spec machines had redrawn the competitive map entirely — Rheinwerk's compact coupe ran a front splitter 140mm deeper, with rear wing endplates tall enough to block the driver's mirror. Privateers who had once finished within two seconds of the factory entries now found themselves lapped before half-distance.
The Cost of Aerodynamic Supremacy
Nordstern committed 12 million Deutsche Marks to the Evo II program in 1991. Rheinwerk's counter demanded a complete retooling of the rear subframe and a bespoke carbon-fiber trunk lid saving 3.2 kilograms. Veloce Corse arrived with four-wheel drive, ending a decade of rear-drive convention in a single homologation cycle. Each escalation was legal. Each was ruinous for anyone without a factory contract.
"The telemetry told us everything the stopwatch could not. These cars were not evolving — they were being replaced."
I spent three weeks at the Nordstern archive in Affalterbach studying data from both seasons. Corner entry speeds at the Nürburgring Südschleife jumped 18 km/h. Peak lateral G through the Fuchsrohre climbed from 1.9 to 2.4. These are not incremental gains — they represent a fundamental redefinition of what a touring car could achieve, and what it cost to field one.
