Don, here's some more information, but your question doesn't have
a simple answer.
(from the AutoWeek site) One of the coolest cars to ever pace the field at Indianapolis Motor Speedway was the 1941 Chrysler Newport, which was given the honor at the 1941 race.
The Newport Dual Cowl Phaeton was a limited-production car that was only produced in 1940 and 1941. At the end of 1941, American auto production was halted in order to make way for war manufacturing. So, in the minds of many, the Chrysler Newport was the last grand pre-war American car.
The car that paced the Indy 500 had a 143-hp, 5.3-liter straight-eight engine, and after the race, became the personal car of Walter P. Chrysler Jr.
In 2013, the car sold at auction for $880,000.

PHOTO BY BARRETT-JACKSONHemmings, June 2010, had a fine article on the pace cars over the years. Here's what was said about 1941: "Chrysler's pace car is probably the pre-war era's most famed, the twin-cockpit 1941 Chrysler Newport. Its driver was Allen B. "Tobe" Couture, a managing engineer who worked for Duesenberg before joining Walter P. Chrysler at Willys. The exact circumstances remain unclear, but in 1941, neither of the 500's co-winners (Mauri Rose, in relief of Floyd Davis) took home a Newport, which remains the only non-production car besides Fisher's early Packard to pace a pre-war event.
"Five such twin-cockpit Newports were built and, according to Newport authority John H. White of Sacramento, California, all apparently survive. It's not clear which one actually paced the start, although it had uncovered headlamps, as do three of the survivors. It's more apparent that the Newport may be the only surviving actual pace car from the pre-war years. The cars that didn't go to winners likely went back to their manufacturers, or were otherwise sold into oblivion."
------------------------So, according to Hemmings, Brooklin got it wrong. But others disagree. Have fun finding an answer! David H
