Berlina was the name given by Lancia to the sedan version (berline means a four-door body literally). Designed by Pininfarina based on the Florida I prototype, this body was actually hand-built by Lancia, as the only one for Flaminia. This was also the only body to last through the entire production period. There were 3,344 Berlinas built with the 2.5 Ltr engine (102/110 bhp specification), and additional 599 with the 2.8 Ltr (128 bhp). They were assembled at Lancia's old facility at Borgo Sao Paolo as the last model to be built there. The very first series had double wipers on the rear window (2 outside, 2 inside). These were deleted on the latter versions.
The Coupé was also penned by Pininfarina, and built by the coach-builder. It was very similar to the Florida II prototype with a 2+2 layout and had a shortened wheelbase, as all 2-door versions. The Coupé has a front nearly identical to the Berlina, but the headlight frames are completely round, whereas they point slightly upwards in the sedan.
The Lancia Flaminia GT, GTL and Convertible were designed and built by Carrozzeria Touring. These two-door versions can be easily distinguished by their four round headlights and a shorter cabin - the wheelbase was decreased significantly for the GT and Convertible, allowing for only two seats to be mounted. The GT was a coupé, while the Convertible was obviously a cabriolet version (with optional hardtop). The GTL, introduced in 1962, was a 2+2 version of the GT with a slightly longer wheelbase. The Convertible was in production until 1964, with 847 made in total (180 with the 2.8), while the GT and GTL lasted until 1965, with 1718 GTs and 300 GTLs made (out of which, 168 GTs and only 3 GTLs with the 2.8).Source: Wikipedia.
