Umdasch (Austria) - AllCarIndex

Umdasch Tuning e.U. was an Austrian tuning and small-series constructor active in the 2010s and based in Alkoven. Its first public project was the PUN 6300, a highly tuned Corvette presented around 2013. Period information associated the car with the Corvette ZR1, positioning the PUN 6300 as a road-going special built around a reworked American V8 and bespoke body/trim. The company later developed the Celero R-6.3, shown mid-decade. No evidence indicated series production beyond prototypes and show cars; activity centered on concept-level vehicles and promotional appearances.
