BMW M5 (G90) Tuning: A New Era of Hybrid Power and Uncompromising Speed

The BMW M5 G90 is a technological masterpiece, combining the 4.4L V8 S68 with an electric motor. In Ukraine, this vehicle has become a new favorite for high-speed highways. Despite its significant weight, the G90 delivers impressive dynamics, but factory restrictions—especially in thermal management and exhaust flow—hold back its true spirit. ATOMIC-SHOP offers comprehensive solutions to transform this heavy sedan into a long-distance interceptor capable of stable performance on AI-100 fuel during Ukrainian summers.

Our approach focuses on unlocking the S68 engine's potential, radically improving cooling with CSF, and tuning the suspension to compensate for the hybrid system's weight.

S68 Engine & Power Modules: Beyond 900 Horsepower

The new V8 S68 paired with the hybrid system produces 727 HP stock, yet its architecture allows for much more. In Ukraine, where owners seek maximum 100-200 km/h results, we offer two primary paths:

• CarBahn & dAHLer Performance Controllers: For those wanting to keep the factory ECU untouched, we offer Plug-and-Play modules. On AI-100 fuel, these solutions reach approximately 900 HP without software interference, making them ideal for new, under-warranty vehicles.
• Eventuri Carbon Intake: An Eventuri intake is a must-have for the G90. It not only improves flow aerodynamics but also reduces Intake Air Temperature (IAT), critical for a hybrid system that generates significant ambient heat.
• CSF High-Performance Charge Coolers: This is the most vital upgrade for G90 in Ukraine. New CSF intercoolers feature 100% larger core volume, eliminating power drops due to heat soak even after multiple high-speed runs.

Exhaust System: Titanium and Sound by Akrapovič

The factory G90 exhaust is heavily muffled due to strict environmental regulations. To return the M5 its aggressive roar, ATOMIC-SHOP recommends:

• Akrapovič Evolution Line (Titanium): A full titanium system that reduces vehicle weight by an impressive 19-20 kg. This is critical for the G90. It adds power and provides a sophisticated acoustic signature that reflects the owner's status.
• Downpipes & OPF Delete: For Stage 2+ builds, we offer downpipes that eliminate exhaust tract bottlenecks, allowing the turbos to spool instantly.

Suspension and Braking: Mastering the Mass

The G90's primary challenge is its weight. To ensure the car doesn't feel heavy in corners, ATOMIC-SHOP offers components that alter the physics of handling:

• KW V4 Coilovers: Professional triple-adjustable suspension allows for perfect compression and rebound tuning. This compensates for the battery weight, making the M5 sharp and planted in corners.
• Endless Brake Pads: Even factory ceramic brakes can feel inadequate during extreme deceleration from 300 km/h. Endless pads provide a stable friction coefficient and the endurance required for such a heavy vehicle.
• Girodisc Rotors: For steel brake versions, we recommend Girodisc 2-piece rotors, which offer better heat dissipation and reduced unsprung mass.

FAQ: ATOMIC-SHOP Technical Expertise

Is it safe to boost the G90 to 900+ HP on stock internals?
The S68 engine is robust, provided cooling is improved. Without CSF intercoolers, the risk of overheating and power loss during Ukrainian summers is very high.

What fuel is recommended for tuned G90s?
For all projects, we strictly recommend AI-100 fuel. This ensures combustion cleanliness and allows the system to run maximum ignition timing without detonation.

Does installing an Akrapovič exhaust void the warranty?
A Slip-On system typically does not affect the engine warranty, but we recommend installation at certified ATOMIC-SHOP centers to ensure all mounting standards are met.
