Overview
- HSR has published renderings and a spec sheet for the Type 859 but the car currently exists only as promotional material while the firm seeks investors to build a physical Prototype Zero.
- The company says the Type 859 will be built from a shortened Audi Coupe B2 donor chassis with full carbon‑fibre bodywork and an integrated roll cage to evoke the Sport Quattro short‑wheel‑base look.
- HSR claims it will mount Audi’s 2.5‑litre 'DAZA' RS3 five‑cylinder engine longitudinally and pair it with an upgraded six‑speed manual, a Torsen centre differential and a mechanical rear limited‑slip differential for mechanical all‑wheel drive.
- Published details differ between outlets: HSR has quoted a starting price of €500,000 and says it holds letters of intent from collectors, while reports list planned runs of either 64 or 84 cars and power claims from roughly 400 kW up to about 600 hp.
- The plan fits a wider trend of small firms building high‑price heritage tributes but key technical claims and production plans are unverified so the next milestones to watch are prototype completion, confirmed build numbers and whether the car meets its sub‑1,200 kg weight and performance targets.
