Volvo Penta has launched the largest marine engine in its history at the Sydney boat show. The D13-1000 is a 13-litre, 1000hp inboard engine. The D13-1000 is equivalent to Volvo Penta’s Inboard Performance System (IPS) range – the D13-IPS1350. Both engines have been designed for yachts up to 120ft.

“It’s truly a landmark product for our marine range, and really gives us a bigger step into the large yacht market,” said Johan Wästeräng, vice president for product management for Volvo’s marine leisure segment, in a statement. “We’ve spent a long time talking to customers about what they want, and refining our engine and IPS designs, so that we can offer exceptional products ideal for world-class vessels.”

Volvo Penta has carried out a major redesign of the 13-litre engine model and drivetrain. New pistons, efficient injectors and improved cooling systems, combine to produce 11% more power than previous engines. Volvo Penta said it is giving yacht owners the possibility to go longer distances at faster speeds.

Volvo Penta’s D13-IPS1350 is an integrated package that matches the new D13 engine with an upgraded IPS pod drive. The 1000hp engine provides the equivalent power of a 1350hp engine when matched to the IPS drive. Upgrades to the IPS pod drive have been made to match the new engine. The D13-IPS1350 package is available in twin, triple or quadruple installation. Quads provide the equivalent of 5400hp. Improved features on the new IPS drive can also be fitted on existing IPS units.

“We have found that there is a demand for greater durability with bigger yachts as the captain has to cruise to wherever the owner wants it to be, so the usage is higher,” said Björn Rönnvall, product manager for the marine leisure segment at Volvo Penta. “Increased low-end torque gives the vessel greater maneuverability at low speeds, and with the compact configuration this means there is more room on board.”

The D13-IPS1350 has been field tested in a 68ft yacht and its data compared to a 1360hp traditional inboard engine from a competitor. Volvo Penta’s unit was lighter with better displacement, used 36% less fuel, had faster acceleration and a higher top speed, and lower noise and vibration.

“Our IPS package has a much greater cruising range than a typical inboard engine,” said Rönnvall. “Customers would be able to cruise from Cannes to the Balearic Islands without having to refuel in Spain, or from Miami to the Bahamas and back again on one tank of fuel. We’re gaining a greater foothold in the large yacht market, so we see an opportunity for even more possibilities in future.”
