Blending innovation, sustainability and style, the Sanlorenzo SX120 is the first composite yacht in the world to feature the pioneering Volvo Penta IPS Professional Platform.
Making its international debut at the Cannes Yachting Festival in September 2025, this largest yacht in the Sanlorenzo crossover range offers expansive onboard spaces and a 70 sqm beach area with a retractable pool and 360° panoramic views from the Upper Deck.
With its 270 GT tonnage and 37 meters in length, the SX120 is the largest vessel built according to Sanlorenzo’s revolutionary SX concept. Combining features from both flybridge and explorer yachts, this new SX120 reimagines life at sea through seamless integration of indoor-outdoor living, adaptability, and sleek, modern aesthetics.
Its strong focus on design principles makes the yacht a perfect fit for the Volvo Penta IPS Professional Platform’s innovative, new dual-power input solution. Onboard the Sanlorenzo SX120, a twin IPS 2700 package is installed with two engines connected per drive.
The end result is the performance of larger engines with a smaller footprint, with the aim to reduce fuel consumption and lower emissions compared with a traditional inboard shaft installation.
This strive towards efficiency gains is fully aligned with Sanlorenzo’s strategy to reduce environmental impact, as well as the commitment to and promotion of sustainability in the nautical sector.
“SX120 represents the natural evolution of a range that has changed the way yachting is conceived and redefined the experience of living on board, introducing a new idea of space, livability and connection with the sea,” says Tommaso Vincenzi, CEO Sanlorenzo.
“The new flagship of the SX line combines functionality and aesthetics, simplicity and elegance, performance and sustainability in a single product. In addition, the SX120 is the first yacht of a big size to integrate Volvo Penta’s new IPS Professional Platform, a compact and efficient system prepared for the use of hybrid energy sources, and designed to improve performance, autonomy and comfort while sailing. This innovative propulsion platform allows for the achievement of certainly unique design solutions related to the use of efficient drives even on large yachts”
The Volvo Penta IPS Professional Platform represents a marine propulsion breakthrough, especially for yachts in 35-55m+ category that straddle the 500GT threshold. This includes a new design, with a new level of intelligence.
This platform, designed for the modular integration of both traditional and alternative energy sources, stands out through its extreme compactness and optimized marine propulsion architecture. These features enable a significant reduction in the engine room space, freeing up valuable volumes that, in the design phase, can be repurposed during the design phase for the owners, guests and crew.
“From the marine propulsion point of view,” says Nicola Pomi, VP Marine Sales Yacht and Superyacht Division, “Volvo Penta’s IPS Professional Platform represents a technological evolution geared toward efficiency. The system makes use of steerable units and hydrodynamically optimized counter-rotating propellers, which are designed for a significant reduction in energy losses and a marked improvement in maneuverability, especially at low speeds.”
A distinctive feature of the platform is the Eco Mode function, which is a new smart feature that automatically adjusts engine power based on real-time demand to optimize fuel consumption, reduce emissions and mechanical wear. The platform will consider optimal fuel consumption and engine run-time hours to engage the engine with the least hours for a given scenario. This aims to improve efficiency and extend service and maintenance intervals.
The advanced marine propulsion package is equipped with a Selective Catalytic Reduction (SCR) exhaust aftertreatment system. The benefits include reduced fuel consumption, as well as reduced emissions and decreased noise levels – all contributing to efficiency and onboard comfort.
The introduction of this technology represents not just engineering progress, but also a new paradigm in the integrated design between naval architecture, functional layout and marine propulsion systems, opening a new phase in the layout and construction of future-oriented yachts.
