Core Selling Points

1. Hot-V Twin-Turbo Design

• Turbos positioned inside the V-angle, shortening exhaust paths for 15% faster response (peak torque at just 

1,500 rpm).

• Twin-scroll technology: Independent exhaust channels per cylinder bank reduce interference, max boost

pressure 1.2 bar (1.5 bar in high-performance versions).

2. Lightweight & Efficient Combustion

• All-aluminum block/heads + plasma-coated cylinder walls (20% lighter vs. iron blocks).

• High-precision direct injection (350 bar fuel pressure), 10.0:1 compression ratio, compatible with 95 RON

(98 RON recommended).

3. Linear Yet Brutal Power Delivery

• Standard: 450 PS (330 kW) / 650 N·m (e.g., G11 750i).

• High-performance: 530 PS (390 kW) / 750 N·m (e.g., G05 X5 M50i), 0-100 km/h in 4.1s.

4. Technical Upgrades (vs. Older N63)

• Revised oil separator (reduces oil consumption issues).

• Upgraded turbo cooling system (extends turbo lifespan).
