With the launch, at the 1947 Paris Motor Show, of the Simca 6, the company’s Nanterre based development office demonstrated a hitherto unseen level of independent thinking for a Simca production model.

The Simca was distanced from its Fiat origins by a modified « Americanised » front end, featuring a widened and lowered front grill, flanked by raised headlights integrated into the wing panels, along the lines featured by the then newly introduced Peugeot 203 and Renault 4CV.

The rear overhang was extended with the addition of a small boot, accessible only from the interior of the car and almost entirely filled by the spare wheel.

Claimed output from the 569 cm³ engine was boosted from 12 to 16.5 bhp achieved at 4,400 rpm.

Despite having its first public presentation at the 1947 Motor Show, the car got off to a slow start, with just 11 produced during the closing month of 1947 and 191 during the whole of 1948:[1] during these years the older Simca 5 remained the company's smaller volume model.
