The 4-cylinder choice guaranteed the kind of fluidity and smoothness that such a layout was designed to provide "naturally". This enabled us to focus on greater commitment to the innovative aspects that new component design could provide. As a result, the V4 Granturismo establishes new benchmarks in terms of design and performance, while endowing these motor creations with an even more solid, regular, fluid and performing heart.
"The final result is a 1,158 cc engine with a thrust of 170 hp. These two statistical peaks alone are enough to provide an idea of the work carried out on this project, reaching dazzling heights at any level, and unequalled in its segment. These are extraordinary numbers, and will ring in the ears of our fans, but they reveal only one side of this achievement."
The V4 Granturismo is no different from its predecessors in terms of process: once again it is the result of a meticulously inexorable team engineering effort, from general layout to final assembly, passing through the selection of new materials and the countless tests carried out during the study phase.
However, there are many other things that make this engine a truly unique product in the history of the Ducati brand. The most surprising is the choice of distribution system: for the first time, instead of the desmodromic valve system, springs have been adopted.
“In this case our goal was to build an engine with the longest possible gaps between maintenance sessions, and spring distribution was the best technical answer to this need.”
The history of Ducati is deeply bonded with the desmo system as developed and perfected by its historic engineer Fabio Taglioni. For over thirty years his extraordinary engineering contributions enabled Ducati to achieve legendary results in terms of performance and competitiveness, while boosting brand engine skills and know-how. Leaving us a heritage of essential expertise empowering us to confront this new challenge:
“During the development of the V4 Granturismo we discovered that the solutions evolved over many years of Desmo application in material selection and construction tolerance worked perfectly when applied to a spring-based distribution... enabling us to reach a result never previously achieved by anyone else."
For example: up to 60,000 km before the first valve clearance check. This segment record is equivalent to one and a half times the earth's circumference.
