The Verdict

The 2021 BMW M4 CSL G82 holds an edge across most measurable criteria, offering more power, quicker acceleration, higher top speed.

Overview

The 2021 BMW M4 CSL G82 and 1991 Porsche 911 964 Turbo stand as two of the most notable Sports Car cars from Modern classic. Both emerged during a period of intense competition, and choosing between them remains a passionate debate among collectors. The 2021 BMW M4 CSL G82 holds a clear advantage in raw power with 543 hp compared to 320 hp, a 223-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the BMW M4 uses a Inline-6 DOHC Twin-Turbo displacing 2,993 cc, while the Porsche 911 relies on a Flat-6 Turbocharged with 3,299 cc. In the sprint to 60 mph, the 2021 BMW M4 CSL G82 edges ahead at 3.6 seconds versus 4.8 seconds. The Porsche 911 carries a weight advantage, tipping the scales 342 lbs lighter. Rarity plays a significant role here — with only 1,000 units built, the 2021 BMW M4 CSL G82 is considerably scarcer than the Porsche 911's 3,660 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
