Overview

Among Grand Tourer enthusiasts, the matchup between the 1973 Bitter CD 5.4 V8 and 1971 BMW 3.0 CS E9 is one for the ages. These Muscle era machines competed directly for buyers' attention and continue to vie for collectors' affections today. The 1973 Bitter CD 5.4 V8 holds a clear advantage in raw power with 230 hp compared to 180 hp, a 50-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Bitter CD uses a V8 OHV displacing 5,354 cc, while the BMW 3.0 CS relies on a Inline-6 SOHC 12V with 2,985 cc. In the sprint to 60 mph, the 1971 BMW 3.0 CS E9 edges ahead at 8.5 seconds versus 9.0 seconds. The BMW 3.0 CS carries a weight advantage, tipping the scales 298 lbs lighter. Rarity plays a significant role here — with only 395 units built, the 1973 Bitter CD 5.4 V8 is considerably scarcer than the BMW 3.0 CS's 11,063 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
