# 2018-2020 BMW M4 CS The BMW M4 CS (Competition Sport) sits between the standard M4 Competition and track-focused GTS, offering 454 horsepower from its twin-turbo 3.0-liter inline-six. Limited to just 1,200 units, it features extensive carbon fiber, adaptive suspension, and weighs 110 pounds less than the Competition. Reviewers praise its sharpened handling dynamics and increased mechanical grip, calling it the most well-rounded M4 of the F82 generation. However, some criticize its harsh ride quality for daily driving and questionable value proposition given its premium over the Competition model. The M4 CS is famous for its striking yellow or red paint options and perfect balance between track capability and street usability. It's best suited for driving enthusiasts seeking weekend back-road thrills and occasional track days, though collectors increasingly appreciate its limited-production status.
The M4 CS requires premium fuel and expensive synthetic oil changes every 10,000 miles. Common issues include premature tire wear from performance rubber and costly carbon ceramic brake replacements ($8,000+). Turbocharged S55 engine may need walnut-blasting for carbon buildup ($500-800). High insurance premiums due to performance classification. Extended warranty recommended for electronics.
