Race-Prepped C8 Corvette vs. Stock C8 Z06 vs. Porsche Turbo S

A Track Day Showdown.


Shootouts between high-performance sports cars are a thrill for enthusiasts, but rarely do they involve direct comparisons between highly modified racers and stock vehicles. Enter Andy Voelkel, a Time Attack champion, and his dad Bret, who decided to settle the score by putting their three prized machines—a race-prepped C8 Z51 Corvette, a stock C8 Z06, and a stock Porsche Turbo S—through their paces at the track.

The Contenders

  • C8 Z51 Corvette (Race-Prepped): Andy’s championship-winning car from the Gridlife Time Attack series. Modified with extensive aero and suspension upgrades, it’s built to dominate lap times.
  • Stock C8 Z06 Corvette: The track-focused monster from Chevrolet, featuring a naturally aspirated 5.5L flat-plane V8 delivering 670 horsepower.
  • Stock Porsche Turbo S: A twin-turbocharged powerhouse with 640 horsepower, known for its all-wheel-drive traction and blistering acceleration.

The Rules

To ensure consistency, Andy took the wheel of all three cars, running them back-to-back on the same track. The goal? To determine which car performed the best in a head-to-head comparison of lap times, handling, and overall driving experience.

The Results

  1. Race-Prepped C8 Z51 Corvette: As expected, the heavily modified car set the benchmark with its purpose-built setup for Time Attack racing. Its lightweight design, aggressive aero, and tuned suspension allowed Andy to push it to the limits, securing the fastest lap of the day.
  2. Stock C8 Z06 Corvette: While not modified, the Z06 proved its mettle, coming remarkably close to the Z51's times. Its sharp handling, screaming flat-plane V8, and advanced suspension system demonstrated why it’s a favorite among track enthusiasts.
  3. Porsche Turbo S: The Turbo S excelled in straight-line speed, leveraging its all-wheel-drive system to deliver insane acceleration off the line. However, it couldn’t match the C8s in terms of cornering and overall lap times, highlighting the Porsche's slight disadvantage in a track-focused setting.

The Surprising Takeaway

While the race-prepped C8 Z51 was the clear winner, the stock C8 Z06’s performance was astonishingly close, proving that Chevrolet’s engineers have created a track weapon right out of the factory. The Porsche Turbo S, while impressive, showed its strengths in acceleration rather than lap-time supremacy, making it more suitable for drag racing than tight, technical tracks.

Conclusion

This shootout demonstrated the impressive capabilities of modern performance cars. The C8 Z06 stands out as a stock marvel that nearly rivals a race-prepped car, while the Porsche Turbo S remains a high-tech supercar with jaw-dropping speed. For those seeking track day glory, the C8 Z06 offers an unbeatable blend of price, performance, and thrills.
