response time by 20% over the N54, delivering peak torque at just 1,750 rpm.
Valvetronic III + Double-VANOS: Throttle-less design with continuously adjustable valve lift and timing,
balancing low-end torque (1.2 bar boost pressure) and high-end power.
Redesigned Timing Chain Guides: Fixes the N54’s tensioner flaw, extending service life to 150,000 km.
Closed-Deck Aluminum Block: Improves cooling efficiency by 30% for sustained performance.
Factory Hardware Supports 450HP+: Achievable with just an ECU tune + intake/exhaust upgrades.
Mitsubishi TD03 Turbo: Better heat resistance than the N54, ideal for track-day durability.
Inline-6 + Balance Shafts: Smoother operation than rival V6 turbos (e.g., Audi 3.0T).
Active Exhaust Valve: Sport mode delivers a more aggressive soundtrack.
