The execution

The homologation road car: twincharged 1.8, permanent AWD, beige Alcantara — Group B detuned to a warranty.

Kerb weight 1’197 kg against the Corsa’s ~950; period sales were slow (~71 cars found buyers 1985–1990), which is why documented, unmodified Stradales are rarer at auction than their Stratos and 037 forebears. Many surviving cars wear later Martini wraps; unrestored factory finishes lead the market.

On the record

- Supercharger and turbocharger on one crank — twincharged from the factory
- 200 homologated; ≈71 believed sold — the rest reportedly broken up or parted out
- Registry documents 42 chassis publicly (exclusivecarregistry.com, 2026)
- Record: €1.04M for a ~2 200 km car, RM Sotheby’s Essen 2019
