probably according to the net the 41 was a big change.....
1940, 1941, 1942 Pontiacs
Series expanded to four for 1940: Special and DeLuxe Sixes and DeLuxe and Torpedo Eights. All listed four-passenger coupes and four-door sedans; Special and the DeLuxes added a business coupe and two-door sedan. There were also DeLuxe "cabriolet" convertibles and a Special wagon. All wore a heavy facelift announced by a more coherent face with a painted prow, still Silver Streaked, dividing a lower-profile horizontal-bar grille. Also in evidence were wider front fenders with fully integrated sealed-beam headlamps.
Wheelbase extended to 117 inches for Special; DeLuxes returned at 120. Sleekest of all were a new Torpedo coupe and sedan on a 122-inch span. Sixes gained two horsepower via light engine modifications. Volume moved up substantially, reaching 217,000 for the model year.
A corporatewide restyle for 1941 gave Pontiacs higher, wider, crisper fenders embellished with additional Silver Streaks, plus a near full-width horizontal-bar grille with prominent center bulge. Running boards were newly concealed via flared door bottoms (except on wagons). Pontiac's six took the form it would retain through 1954, being bored out to 239.2 cid for 90 bhp. The veteran straight-eight was tweaked to 103 bhp in 1940, where it would remain through '47.
