• Price-to-performance: M4 CSL significantly better value
• Daily usability: 911 Turbo more livable
• Track capability: M4 CSL more focused

The M4 CSL costs $60,000-$80,000 less than a 911 Turbo while delivering comparable or superior track performance^[2].

How M Series Ranks Against All Performance Brands

BMW M Series competes at the highest performance levels, though some rivals are faster.

Performance Hierarchy (0-60 MPH):

1. Tesla Model S Plaid: 1.9 seconds
2. Porsche 911 Turbo S / M5 CS: 2.6 seconds (tied)
3. Lamborghini Huracán: 2.8 seconds
4. Mercedes-AMG GT 63 S: 3.1 seconds
5. Audi RS7: 3.3 seconds

BMW M Series vehicles sit near the top of the performance hierarchy, with only Tesla’s instant electric torque and seven-figure supercars accelerating faster^[1].

Track Performance: Beyond Straight-Line Speed

Nürburgring Lap Times

The Nürburgring Nordschleife serves as the ultimate track performance benchmark.

Official M Series Lap Times:

• M4 CSL: 7:20.2 (fastest BMW production car)
• M5 CS: 7:29.9 (fastest sedan)
• M8 Competition: 7:32+ (estimated)
• M2 CS: 7:36.0

The M4 CSL’s purpose-built track focus delivers a Nürburgring time that rivals dedicated sports cars costing twice as much^[2].

Handling and Cornering Speed

Track performance requires more than straight-line speed.

Track-Focused Technology:

• M Compound brakes: Carbon-ceramic optional, resist fade
• Adaptive M suspension: Electronically controlled dampers
• Electronic stability systems: Configurable intervention levels
• Weight distribution: Near 50/50 front/rear balance

The M4 CSL’s lightweight construction and track-tuned suspension enable higher cornering speeds than heavier M5 and M8 models despite less power^[2].

Best M Series for Track Days

Different M models suit various track day priorities.

Track Day Recommendations:

• M4 CSL: Purpose-built track weapon (if budget allows)
• M3 Competition: Best performance-per-dollar value
• M5 CS: Fastest sedan with passenger capability
• X5 M: Best SUV for performance driving schools

The M3 Competition offers 90% of the M4 CSL’s capability at 55% of the cost, making it the smart track day choice for most enthusiasts.

Street vs Track Performance

Street and track priorities differ significantly for M car buyers.

Street Performance Priorities:

• Daily comfort: Adaptive suspension essential
• Fuel economy: 15-18 mpg typical vs 8-12 mpg on track
• Tire longevity: Street tires last 30,000+ miles
• Launch control: Rarely used in real-world driving

Track Performance Priorities:

• Lap consistency: Brake and tire thermal management
• Weight: Every 100 lbs matters on circuit
• Cooling: Oil and brake cooling systems critical
• Tire choice: Cup 2 tires deliver 2-3 second lap advantages

According to Autvex track testing, most buyers never exploit more than 50% of modern M car capability on public roads, making track days essential for experiencing full performance potential.

Expert Recommendations and Final Verdict

Best Overall Fastest M Series

The M5 CS represents the pinnacle of BMW M performance based on comprehensive testing^[1].

M5 CS Advantages:

• Fastest real-world acceleration: 2.6 sec 0-60, 10.7 quarter-mile
• Balanced capability: Four-door practicality with supercar speed
• Investment potential: Appreciating rather than depreciating
• Exclusivity: Limited production enhances ownership experience

For buyers seeking the absolute fastest BMW M Series vehicle with daily usability, the M5 CS remains unmatched—if they can find one.

Best Value High-Performance M Car

The M3 Competition xDrive delivers the best performance-per-dollar ratio.

Value Proposition:

• M3 Competition xDrive: $79,000
• M4 Competition: $81,000
• Performance: 3.4 sec 0-60, 503-543 hp
• Availability: In stock at most dealers

The M3 Competition provides 85% of M5 CS performance at 55% of the cost, making it the smart choice for enthusiast drivers on realistic budgets^[4].

Should You Buy for Speed Alone?

Pure speed rarely justifies M car ownership without considering broader factors.

Important Considerations:

• Daily usability: Will you actually use 600+ hp regularly?
• Alternative options: Lexus LC 500, Genesis G80, Cadillac CT5-V Blackwing
• Insurance reality: $500-$800 monthly for young drivers
• Depreciation: Standard M cars lose 40-50% in 5 years

Autvex recommends test-driving slower M cars (M240i, X3 M40i) before committing to full M Division models—many buyers find the gap smaller than expected in real-world driving.

Future of M Series Performance

BMW M’s electrification strategy will reshape the brand’s character^[5].

Future Trends:

• Electrification expansion: More hybrid and full-electric M models
• Weight concerns: Battery packs add 800-1,000 lbs
• Performance paradox: More power, similar acceleration due to weight
• Preservation: Gas-powered M cars becoming collectibles

The 2022 M5 CS may represent the peak of naturally aspirated V8 M performance before electrification fundamentally changes the formula. Collectors should consider gas-powered M cars while still available new.
