Overview
The Bentayga V8 pairs Bentley’s SUV platform with the highly tuneable EA825 twin turbo V8, making it one of the most responsive modern Bentleys to calibrate. The stock tune delivers excellent drivability but still leaves substantial room for software only improvements. Stage 1 noticeably strengthens launch and midrange acceleration while keeping factory refinement. Stage 2 adds sharper upper rpm performance when matched with freer flowing exhaust parts and improved charge cooling.
Key Features
- excellent SUV V8 tuning candidate
- rapid spool and strong midrange
- refined daily behavior maintained
- strong launch feel
- ideal for Stage 2 airflow upgrades
