V4 Granturismo: the engine of the next generation of Ducati Multistrada
Ducati presents the new Granturismo V4 engine: it will equip the new Multistrada V4, to be unveiled on November 4
The Granturismo V4 has been developed for maximum operating smoothness and has record service intervals
Compact and light, efficient, endowed with rich torque values: an engine designed for âadventurousâ use, offers both thrills and sportiness
Borgo Panigale (Bologna, Italy), October 15, 2020 – A new era begins at Borgo Panigale as Ducati presents to the public the new V4 Granturismo, the engine that will equip the long-awaited new generation of Ducati Multistrada: which will be shown to the world on Wednesday 4 November.
An extremely compact, light, powerful and torque-rich engine, designed to meet the needs of âadventurousâ use without neglecting emotion and sportiness.
Built with the latest generation technology as well as first-class materials available, in order to guarantee both durability and reliability, the Granturismo V4 is distinguished by its record maintenance intervals for a motorcycle engine and was created as the heart of a high-performance and dynamic bike, ready to explore all corners of the planet with its owner.
The engine was presented to the public with a video in which Claudio Domenicali – CEO of Ducati – the engineers and technicians who have followed its development reveal all its secrets and characteristics to Ducati enthusiasts.
Each technical choice made during the development of the V4 Granturismo project was aimed at ensuring maximum fluidity of operation combined with a substantial extension of maintenance intervals.
The new distribution includes a spring-loaded valve return system, bringing the maintenance intervals of the V4 Granturismo to 60,000 km. This has been achieved thanks to the in-depth expertise that Ducati has acquired in the use of materials, treatments and technical solutions developed around the Desmodromic system. All of this, applied to a spring loaded valve return system that puts less strain on components compared to the Desmo, produced to set an exceptional milestone never before achieved by a motorcycle engine. In addition, the engine ensures great regularity of operation both at low speed and load, without forgetting the foolproof performance, the power at high speed and the range of a genuine sports engine: the V4 Granturismo delivers 125 kW (170 hp) at 10,500 rpm. and a maximum torque of 125 Nm (12.7 Kgm) at 8,750 rpm. All this while respecting the strict Euro 5 homologation standards.
With a weight of 66.7 kg, the Granturismo V4 can boast of record lightness, being 1.2 kg lighter than the Testastretta twin-cylinder used on the previous Multistrada 1260. The displacement of 1,158 cm3 was found to be the perfect connection point in terms of performance, lightness and size of a V4 engine, capable of being incredibly light and compact. Compared to the previous generation engine, the Granturismo V4 is 85mm shorter, 95mm lower and only 20mm wider. This compact layout allowed Ducati engineers to house the engine in the frame more efficiently and centrally to positively influence the position of the bike’s center of gravity, with all the resulting benefits.
The Granturismo V4 also inherits certain elements from Ducati’s experience in the racing world, such as the decision to adopt a counter-rotating crankshaft, which improves the handling and agility of the bike, and to exploit the “Twin Pulse” technology. , capable of delivering power and perfectly manageable at every speed.
To avoid a decrease in thermal comfort due to the heat transmitted by the rear cylinders, the V4 Granturismo adopts the strategy of deactivating the rear bench at idle. In this way, when the motorcycle is stationary, the combustion process in the cylinders is stopped and this improves the thermal comfort of the rider and the passenger thanks to the reduction of the temperature while reducing the fuel consumption.
