1940 Lincoln Zephyr

"The Zephyr was powered by a small V12 engine developed from Ford's Flathead V8 and unrelated to the previous Lincoln V12 engines. The side-valve engine was quite compact, especially compared to the tall L-head Lincoln 12, allowing a low hood. But its V8 roots would prove troubling, with bearing and crankshaft problems becoming common. The 1936 to 1939 models were 267 in³ (4.4 L) with hydraulic lifters added in 1938. 1940 and 1941 cars used an enlarged 292 in³ (4.8 L) engine, while 1942 and early 1946 models used a 306 in³ (5.0 L). Late 1946 to 1948 Lincolns based on the Zephyr used a 292 in³ (4.8 L). The original engine had 110 hp (82 kW) and gave the car a top speed of 90 miles per hour (145 km/h). The body was monocoque construction and very rigid, but surprisingly light for its size. The first model had a weight of 3,350 lb (1,520 kg). Suspension was transverse springs front and rear, already seen as outdated when the car was introduced. Brakes were cable-activated for 1936 to 1938; 1939 and onwards were hydraulic. The Zephyr was the first Ford product to have an all-steel roof."
