A rare once-Canadian-owned 1957 Jaguar XKSS is expected to sell for a staggering $16 million USD when it crosses the block at the Amelia Island Concours D’Elegance auction held March 10 thru 12.

The XKSS was a unique factory race car conversion model based on the highly successful Jaguar D-Type racer. To render the XKSS street-legal, Jaguar added a conventional windshield, folding hood, passenger-side door, dash instrumentation, more comfortable seating, a luggage rack, bumpers, and signal lights.

Like its race car analogue, the XKSS was powered by a 3.4-litre inline-six, featuring a then-technologically advanced double-overhead camshaft valvetrain. At full song, the engine was capable of producing 250 horsepower, good for a rip from standstill to 60 mph (96.5 km/h) in 5.2 seconds and a top speed of 149 mph.

This particular XKSS, chassis number 716, was first purchased by Stanley C. McRobert of Montreal, Quebec, on June 12, 1957. McRobert raced the car to several victories before selling it to successive Canadian owners, who also raced it to circuit-track victories. The car then traded hands between Americans and Brits.

XKSS 716 will be the first of its kind to hit the auction block in a decade.

While this XKSS’s original racing pedigree and pristine condition will keep its value sky-high, those looking for a fresh copy of the XKSS for a more palatable price will be pleased to know Jaguar is resuming production of the XKSS.

The British automaker will produce nine copies of the XKSS with the intention of replacing nine original D-Type chassis that were destined to become XKSS road cars, but were lost in a factory fire before their conversions were complete.
