The exact top speed of a BMW M850i without its electronic limiter can vary significantly, especially when performance enhancements are applied. For a BMW M850i that has undergone professional tuning, its top speed with the limiter removed is notably higher than the factory-set limit.
What is the Untuned Top Speed of a Stock BMW M850i?
Typically, stock BMW M850i models are electronically limited to a top speed of 250 km/h (155 mph). This limiter is a common feature across many high-performance German vehicles, often implemented for safety and regulatory reasons. Without this limiter, the stock vehicle could theoretically achieve a higher speed, though the precise figure for an untuned model without its limiter is not widely specified in general contexts.
How Does Tuning Affect Top Speed?
When a BMW M850i is enhanced with specialized performance tuning, such as a G-Power tuning kit, its capabilities extend far beyond the stock specifications. Such modifications boost engine output significantly, allowing the vehicle to reach much higher speeds once the factory limiter is disengaged.
- A G-Power tuned BMW M850i benefits from a substantial increase in power, bringing its output to an impressive 670 horsepower.
- This significant power boost, combined with the removal of the electronic speed limiter, enables the vehicle to achieve a top speed of 320 km/h (198 mph). This demonstrates the immense potential of the M850i when its performance is fully unleashed.
Performance Snapshot: Tuned BMW M850i
To illustrate the impact of such tuning, here's a quick look at the enhanced performance metrics for a G-Power tuned M850i:
| Metric | G-Power Tuned BMW M850i |
|---|---|
| Engine Output | 670 hp |
| 0-100 km/h (62 mph) Time | 3.1 seconds |
| Top Speed (Limiter Removed) | 320 km/h (198 mph) |
This information clearly shows that removing the limiter, especially in conjunction with power upgrades, transforms the M850i into a true high-speed contender.
