Delahaye 175 was an automobile manufactured by Delahaye between 1947 and 1951. The last of the large Delahayes, the type 175 was essentially a brand new chassis and engine. The chassis bore little resemblance to the preceding Type 135, other than the cockpit area with its driveshaft tunnel and welded stamped-steel floor, which assembly formed a rigid structural member. The new 4.5-litre engine was visually quite similar to the Type 135, but significantly improved. It had seven main bearings versus the Type 135's four, and its cylinder head had six intake and six exhaust ports, twelve in all, versus nine in the standard Type 135 ( albeit a rare few Type 135 racing engines had twelve port heads). The larger engine was stronger and breathed better <Club Delahaye archive data, obtained from it
