The latest creation from ASCO Tuning is turning heads in the super-sedan world.
They’ve taken the brand-new G90 BMW M5 and pushed it into truly savage territory — a street-legal 1000 horsepower monster.
This is not just another chip tune. This is a complete transformation.
The Base Car – G90 M5 as Foundation
The new M5 already arrives from the factory as one of the most powerful production sedans ever built.
With its plug-in hybrid V8 system it delivers serious factory performance numbers and surprisingly good everyday manners.
ASCO saw huge potential in this new platform — especially in the enormous power reserves hidden inside the new S68 engine and the extremely robust hybrid drivetrain.
Heart of the Monster – 1000 Horsepower ASCO Package
ASCO Tuning didn’t simply raise boost and call it a day.
The company developed a very comprehensive upgrade package built around massive increases in every major power-producing area.
Here are the main ingredients of the 1000 hp program:
- Completely new, much larger turbocharger system with reinforced internals
- Heavily revised intake system with significantly larger charge-air cooler
- Upgraded high-pressure fuel system capable of supporting 1000+ hp
- Custom engine software completely rewritten for the new hardware
All these changes work together to transform the character of the car from “very fast luxury sedan” into “ferocious four-door supercar killer”.
Chassis & Drivetrain Upgrades – Can It Actually Use the Power?
Getting to 1000 hp is one thing.
Making 1000 hp usable — especially in a relatively heavy sedan — is a completely different challenge.
ASCO addressed this problem with a very serious hardware upgrade list:
- Upgraded coil-over suspension with considerably stiffer spring rates
- Larger and more powerful carbon-ceramic brake package
- Strengthened drive shafts and reinforced rear differential internals
- Revised engine & transmission mounts for better power transfer
These changes make a night-and-day difference when the driver starts to really push the car.
How Does the 1000 hp ASCO M5 Actually Drive?
Early customers and journalists who have driven the car describe a very special experience.
Below approximately 4500 rpm the car still feels surprisingly civilized.
Then the turbos wake up properly — and everything changes in an instant.
The acceleration becomes violent in a way very few sedans on earth can match.
Many experienced drivers say it pulls harder in the upper rpm range than most pure supercars in the same price range after modifications.
The most surprising part for many people?
The car still maintains extremely good drivability in normal daily driving modes when the owner wants to stay under the radar.
Looks – Subtle Aggression or Full Show Car?
ASCO offers this 1000 hp package in two different visual directions.
The first philosophy stays relatively stealthy — just slightly more aggressive wheels, a subtle carbon lip kit, and maybe a discreet rear wing.
The second direction goes full statement mode with:
- Much more aggressive widebody kit
- Massive carbon fiber hood with vents
- Extremely large rear wing
- Quad exhaust system with dramatic outlets
Both versions are popular — it really depends on whether the owner wants to shock people or just silently humiliate more expensive supercars at the traffic light.
Final Thoughts – The New King of Super Sedans?
The ASCO-tuned 1000 hp G90 M5 is currently one of the most extreme yet still daily-drivable super-sedans on the planet.
It combines brutal acceleration most people have never experienced in a four-door car with surprising levels of comfort and luxury when driven gently.
For people who want the ultimate “sleeper” weapon — or simply the most ferocious M5 ever created — this new ASCO creation sits at the very top of the current food chain.
FAQs
How much horsepower does the stock G90 M5 have?
The factory BMW M5 G90 is rated at approximately 717 hp from its plug-in hybrid V8 system.
Is the 1000 hp ASCO M5 still street legal?
Yes — when built as a street-legal package it keeps all necessary emissions equipment and maintains street legality in most markets.
Can you order the 1000 hp package directly from ASCO?
Yes. Both complete cars and upgrade packages for existing G90 M5 owners are available.
How much faster is the 1000 hp version compared to stock?
The difference is massive — most independent tests show 0–60 mph times dropping into the low-to-mid 2-second range.
Do you lose the electric-only driving mode with this upgrade?
No. Most owners keep the ability to drive in full electric mode for short distances — one of the big advantages of this package compared to pure combustion tuning.
