Side-by-side POV video taken at Thunderhill Raceway — an epic lap battle between the automatic-transmission G80-chassis BMW M3 Competition and the manual-transmission 6-speed G82 BMW M4.

Both brand-new BMWs from the press fleet, factory tires. 

**LAPTIME DISPLAYED IS CORRECT — though I swapped the graphics at the end**

Randy's colorful commentary thanks to bad transmission programming. 🤣
