The current Lancia Thesis is 4,888 mm long, 1,830 mm wide and 1,465 mm tall, on a 2,803 mm wheelbase.
Only one generation of this model is in our catalogue, so there is no size history to compare yet.
Exterior figures are manufacturer specifications for the Thesis, averaged per generation across its variants and shown for the most common body style. Generations with the same size are merged. Boot capacity is the seats-up figure where the manufacturer quotes one.
