Overview

The rivalry between Italy and Germany automotive industries has produced legendary matchups, and the 1947 Ferrari 125 S versus 1955 Porsche 550 Spyder is among the most fascinating. These two cars represent the best of their national engineering schools. On paper, the two are remarkably close in power output, with the 1947 Ferrari 125 S producing 118 hp and the 1955 Porsche 550 Spyder delivering 110 hp. Under the hood, the contrast is notable: the Ferrari 125 S uses a V12 SOHC displacing 1,497 cc, while the Porsche 550 Spyder relies on a Flat-4 DOHC 8V with 1,498 cc. The 1955 Porsche 550 Spyder claims a higher top speed at 137 mph compared to 106 mph. The Porsche 550 Spyder carries a weight advantage, tipping the scales 354 lbs lighter. Rarity plays a significant role here — with only 2 units built, the 1947 Ferrari 125 S is considerably scarcer than the Porsche 550 Spyder's 90 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
