The Lancia Stratos Zero concept car, unveiled in 1970, was powered by a mid-mounted 1,592 cc, 60° V6 petrol engine sourced directly from the Ferrari Dino 246 GT. This engine featured a dual overhead camshaft (DOHC) design per bank and was naturally aspirated, producing approximately 195 PS. Its compact, high-revving character was chosen to match the Stratos Zero's radical wedge design and showcase potential performance.
Fitted exclusively to the one-off Stratos Zero show car, this Ferrari-sourced engine was not intended for production in a Lancia. It demonstrated the feasibility of a mid-engine layout for a future rally weapon, prioritizing power-to-weight and a distinctive exhaust note over emissions or economy. As a prototype component, it predated formal emissions regulations for such applications.
One documented characteristic is its origin as a Ferrari Dino unit, noted in period Lancia and Pininfarina documentation. This engine was never modified by Lancia for the Zero and served purely as a running chassis component. The production Stratos HF that followed used a completely different, Lancia-developed V4 engine.
This engine, as installed in the 1970 Stratos Zero prototype, predates standardized Euro emissions regulations and was not type-approved for road use (VCA UK Type Approval historical records).
The engine in the Lancia Stratos Zero is a 1,592 cc 60° V6 petrol engine, sourced from the Ferrari Dino 246 GT and installed for demonstration purposes (1970). It combines dual overhead camshafts per bank with a high-compression design to deliver a peaky, high-RPM power band. Designed for performance in its era, it predates formal EU emissions standards for prototypes.

The DOHC V6 layout provides a thrilling, high-revving character but demands meticulous maintenance typical of 1970s Ferrari engines, including precise valve clearances and carburetor synchronization. Using the specified SAE 20W-50 mineral oil is critical. As a non-production installation in the Stratos Zero, there are no Lancia-specific service procedures; maintenance would follow Ferrari Dino protocols. The engine's value and rarity make preservation paramount.
Oil Specs: Requires SAE 20W-50 mineral oil specification (Ferrari Owner's Manual). Modern synthetic oils may not be suitable without expert consultation.
Emissions: Prototype installation; not subject to road vehicle emissions regulations (VCA Historical Records).
Power Ratings: Measured under DIN 70020 standards for the Ferrari Dino 246 GT engine (Ferrari Performance Data 1970).

The engine installed in the Lancia Stratos Zero was a unique, one-off installation. It was not a Lancia engine but a Ferrari Dino 246 GT unit used solely for the 1970 prototype. This engine was never adapted or modified by Lancia for production and has no interchangeability with any production Lancia Stratos HF models, which used a completely different V4 engine. All documentation refers to its origin as a Ferrari component.
The engine in the Stratos Zero is unequivocally a Ferrari Dino 246 GT engine. Identification is based on its origin, not a Lancia part number. Key identifiers include the Ferrari engine number stamped on the block (typically starting with '000'), the distinctive 60° V6 layout with twin cam covers per bank, and the trio of Weber 40 DCN carburetors. It is fundamentally different from the Lancia V4 used in the production Stratos HF. Any service or parts must reference Ferrari Dino 246 GT documentation.
As a 1970 Ferrari Dino engine installed in a non-production prototype, the primary consideration is its age and the typical maintenance needs of high-performance engines from that era. Ferrari service documentation from the period highlights the need for regular valve adjustments and carburetor maintenance. Owner club data for the Dino 246 GT suggests these are the most common areas requiring attention for preservation.
