There’s been a lot of buzz around Achates’ 2.7-liter two-stroke diesel engine which it featured in a late model Ford F-150 at the Detroit Auto Show earlier this year.
Since then many of us have been anxious to hear and watch the opposed-piston (OP) powerplant in action which the San Diego-based company says gets a jaw-dropping 42 MPG (CAFE Combined) and 37 MPG in the OP gas compression ignition variant.
The wait is over thanks to a video posted by Achates this week. Now the next question…when can we drive it?! While there have been no public announcements of the 2.7-liter two-stroke entering production, we’d be happy to welcome the innovative oil burner into the family. Though relatively small with no valve train, it delivers 270 horsepower and 480 lb. ft. of torque.
Achates told us earlier this year that they’ve worked through emissions issues long associated with two-stroke diesels. Achates teamed up with Saudi-owned petroleum giant Aramco and has been testing the truck at Aramco’s research center in metro-Detroit.
Though the video’s only been up since Monday, it’s generated nearly three dozen comments and 72 thumbs up and no thumbs down.
“It really does sound like the old Detroit Diesel Jimmy Screamer. I love it!” writes John Anderson.
