Passenger-vehicle-grade diesel engines continue to be at a stalemate in the United States, with the ever-stringent emissions limits mandated by our Environmental Protection Agency snuffing the life out of globally available diesel engines before they even make it to our shores. Land Rover's new 4.4-liter diesel V-8, which can be found in the British firm's 2011 Range Rover, meets Euro5 emissions standards but is unable to pass the requisite tests in the U.S. Our current 2010 standards are reportedly the equivalent of Europe's Euro6 standards, which don't go into effect until 2014 on the Old Continent. Barring any significant alterations to future EPA standards, Land Rover insiders have told
Autocar the oil-burning 4.4-liter V-8 could cross the Atlantic then.
On our soil, the 2011 Range Rover is motivated by either a normally aspirated 5.0-liter V-8 developing 375 horsepower, or a supercharged V-8 of identical displacement producing 510 horsepower.
