Engine Room

Green and clean may have a fuddy-duddy reputation to some people—good for the environment but some say not much fun—however, Volvo Penta is changing that with its new D11 725-hp diesel engine. When paired with the company’s new IPS950 pod drives, the robust powerplant is more fuel efficient and pollutes less.

The D11 engine’s innovative technology creates an optimized air and fuel pressure ratio, which increases combustion efficiency. After-cooling provides more engine power, and on the exhaust end it simply emits less particulate pollution. That’s because the new D11 engine must comply with the world’s most stringent environmental legislation, U.S. EPA Tier 3, which comes into force this year. The particulate emissions requirements are 40 percent lower when compared with the old Tier 2 levels.

“The IPS800 and 950 are matched with the new 625- and 725-horsepower D11 diesel engines, providing a perfect combination of torque, speed and maneuverability for 40- to 60-foot flybridge yachts and sports cruisers,” says Marcia Kull, Vice President, Marine Sales North America, Volvo Penta of the Americas. “The result is two new and reliable drive packages both with a unique high torque.”
