The term “biturbo” makes the heart of every car enthusiast beat faster. Who doesn’t dream of a powerful engine that effortlessly climbs every mountain and provides adrenaline on the highway? But what exactly is behind this technology and what advantages does it offer?
What Does Biturbo Mean?
“Biturbo” simply means “two turbochargers.” Instead of just one turbocharger, which increases engine power by supplying compressed air, a biturbo system uses two turbochargers working together. This can happen in different ways, depending on the engine design and desired result.

Functionality and Advantages of a Biturbo System
There are different types of biturbo systems, but they all have one thing in common: they use exhaust gas energy to increase engine power.
- Sequential Biturbos: In this system, initially only a smaller turbocharger is active, which ensures quick response at low speeds. Only at higher speeds does the second, larger turbocharger engage to provide full power. This allows for an optimal combination of powerful acceleration and high top speed.
- Parallel Biturbos: Here, both turbochargers work simultaneously to compress the intake air. This achieves a smooth power delivery across the entire speed range.
- Register Turbocharging: In this system, depending on the load condition, one or two turbochargers are activated. This enables particularly efficient use of exhaust gas energy and reduces fuel consumption.
“The correct tuning of the two turbochargers is crucial for the optimal power delivery and efficiency of a biturbo engine,” explains Dr. Ing. Markus Schmidt, engine developer at a renowned German car manufacturer.
Advantages of Biturbo Engines:
- More Power: Due to the dual charging, a biturbo engine can generate significantly more power than a comparable naturally aspirated engine or an engine with only one turbocharger.
- Better Response: Especially with sequential biturbos, the use of a small turbocharger ensures a spontaneous response even at low speeds.
- Lower Consumption: Through the efficient use of exhaust gas energy, biturbo engines can have lower fuel consumption despite higher performance.
What to Consider When Operating a Biturbo Engine?
Like any turbo engine, a biturbo unit requires special care and maintenance. Regular oil changes with high-quality oil are mandatory to protect the bearings of the turbochargers.

Frequently Asked Questions about Biturbo:
- What is the difference between Biturbo and Twin-Turbo? In principle, both terms describe the same system: two turbochargers that provide more power.
- Are biturbo engines more prone to defects? Basically, biturbo engines are just as reliable as other engines. However, due to the more complex technology, they are somewhat more maintenance-intensive.
- Can you convert a normal engine to biturbo? In principle, this is possible, but it requires extensive changes to the engine and is associated with high costs.
Conclusion
Biturbo technology is fascinating and offers many advantages for drivers who crave more power and driving pleasure. Anyone who opts for a vehicle with a biturbo engine should, however, be aware of the higher maintenance costs.
