Today new stats on Jaguar's upcoming 2.2-liter diesel for the XF sedan have emerged. We've already seen the core details of the new engine--in late March, Jaguar released an official teaser of the oil-burner inside a thinly disguised "development mule."

At the time we figured it was unlikely the engine would come to the U.S., and we still doubt it will--but a New York Auto Show unveiling at least raises the spectre of consideration for our market. At a whopping 52.2 mpg rating, according to Ward's Auto, the proposition would certainly be attractive to people looking for an efficient, yet still stylish and decidedly non-hybrid-looking luxury sedan.

Packing 190 horsepower and 332 pound-feet of torque, the 2.2-liter diesel won't set the performance world aflame, but at the same time, it would more than meet most drivers' needs. A top speed of 140 mph and 8.5-second 0-60 mph performance is nothing to sneeze at.

The new diesel-powered XF is also expected to show off a ZF-developed eight-speed automatic transmission and new front and rear fascia as well. We'll be live at the New York Auto Show with a full contingent, so look forward to the first live shots, full details, and more next week.
