Since the D4 and D6’s initial release, there have been over 100,000 units delivered. But now Volvo Penta has given its next-generation D4 & D6 propulsion packages a comprehensive overhaul. The improvements are focused on the things that matter to boat owners: lowering the cost of ownership and improving reliability, durability, and performance.
The list of upgrades to the D4/D6 is long and includes a new engine management system, new fuel injection system, new turbocharger, and a new supercharger. The cylinder head, pistons, and valves are new, to cope with the increased performance, and other engine components have also been made stronger to handle the higher power output. The changes are more than a facelift, with most components reengineered.
The D4 and D6 deliver performance outputs of between 150 to 480 hp. In top specification, the D4 now has a maximum output of 320 hp, while the D6 boasts 480 hp. Not only do these engines offer up to 10% more power across the range, but they also cost less to maintain, with longer service intervals and fewer service items.
