CHERRY HILL, New Jersey — Subaru of America released details on the European-market 2009 Subaru Forester 2.0D today. It will get the 2.0-liter horizontally opposed diesel four-cylinder already offered in the Euro-spec Subaru Legacy, along with a new six-speed manual transmission.Guaranteed to be the volume-selling Forester in Europe, the 2.0D has a 2.0-liter turbocharged diesel-4 rated at 145 horsepower at 3,600 rpm and 258 pound-feet of torque from 1,800-2,400 rpm. As in the Legacy, this engine uses an aluminum block — uncommon among diesels, which typically employ an iron block to withstand the vibration of their inherently tall compression ratios.That horsepower figure might not impress given that the U.S.-market Subaru Forester gets 170 hp out of its normally aspirated 2.5-liter gasoline boxer-4 and 224 hp from the turbocharged 2.5-liter in the Forester 2.5XT. However, the boxer diesel has significantly more torque than its gasoline counterparts. Even the 2.5XT offers just 226 lb-ft. Subaru says the diesel 2009 Subaru Forester has a 4,400-pound tow capacity.Just as significant is the introduction of a new six-speed manual transmission. Its gear ratios are much closer together than those of the five-speed manual Subaru offers on U.S.- and European-market Foresters, making it much better suited for a diesel engine's narrow power band. In addition, a tall 0.557/1 6th gear should promote better fuel economy during highway travel.On the emissions front, the 2009 Subaru Forester 2.0D gets a closed-type particulate filter in lieu of the open-type filter in the diesel Legacy. Subaru says this type of filter can treat higher volumes of particulate matter, which would make it better suited for the heavier Forester. The filter is packaged with the turbocharger at the lower part of the engine.What this means to you: Still no firm date on when Subaru will risk selling its boxer diesel to us Americans, but the chunky Forester is probably our best hope. — Erin Riches, Inside Line Senior Editor
