The 1938 Jaguar SS100 3.5 Litre Roadster emerges ahead in most objective measures, offering more power, higher top speed, lighter weight. The 1921 Bentley 3 Litre counters with its unique character, but the numbers favor its rival. Still, both are remarkable machines, and the final choice often comes down to which driving experience speaks to you.
The 1921 Bentley 3 Litre and 1938 Jaguar SS100 3.5 Litre Roadster stand as two of the most notable Sports Car cars from Pre-war. Both emerged during a period of intense competition, and choosing between them remains a passionate debate among collectors. The 1938 Jaguar SS100 3.5 Litre Roadster holds a clear advantage in raw power with 125 hp compared to 80 hp, a 45-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Bentley 3 Litre uses a Inline-4 SOHC displacing 2,996 cc, while the Jaguar SS100 relies on a Inline-6 OHV with 3,485 cc. The 1938 Jaguar SS100 3.5 Litre Roadster claims a higher top speed at 100 mph compared to 80 mph. The Jaguar SS100 carries a weight advantage, tipping the scales 392 lbs lighter. Rarity plays a significant role here — with only 118 units built, the 1938 Jaguar SS100 3.5 Litre Roadster is considerably scarcer than the Bentley 3 Litre's 1,622 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
