Guinness World Record holder Miko Marczyk completed a 2,831-kilometer journey across multiple European nations on a single tank of fuel in a Skoda Superb 2.0 TDI during 2025, achieving a fuel consumption rate of 2.6 liters per 100 kilometers. Marczyk followed this with an electric vehicle range trial, driving an Audi A6 Sportback e-tron Performance 1,338 kilometers on a single charge.
The Bottom Line
- Extreme Efficiency Limits: Marczyk’s trials demonstrate that internal combustion and electric powertrains can exceed standard operational ranges by optimizing variables under controlled test conditions.
- Operational Technique Impact: Driver behavior, including predictive traffic observation and maintaining steady highway velocities between 100 km/h and 120 km/h, can lower fuel consumption significantly in daily transit.
- Maintenance Variables: Ancillary factors such as tire pressure and vehicle payload directly alter rolling resistance and energy draw across both fuel and battery platforms.
Mapping the Route and Execution Parameters
The combustion endurance test began in Łódź, Poland, routing through Germany to Disneyland near Paris, and returning via Belgium, the Netherlands, and Germany. The test concluded when the vehicle exhausted its fuel supply approximately 50 kilometers short of Poznań. The operation spanned roughly 35 hours of continuous transit, maintaining an average speed of 85 km/h.
Subsequent testing shifted to electrification, utilizing the Audi A6 Sportback e-tron Performance. Marczyk traversed 1,338 kilometers on a single charge. This route originated in Zakopanem and proceeded through Kraków, Sandomierz, Warsaw, and Toruń before reaching Hel, prior to heading back southward.
Quantifying Fuel Reduction Through Driving Technique
While these feats relied on specialized conditions tailored for maximum range optimization, Marczyk notes that underlying principles translate directly to commercial and consumer driving habits. Here is the math: applying disciplined ecodriving techniques can reduce a vehicle’s fuel or energy consumption significantly without adding travel time.
The primary mechanism involves anticipation. By observing traffic flow and signal changes from 200 to 300 meters ahead, drivers can decelerate gradually rather than maintaining high speeds until an abrupt stop. Because re-accelerating a stationary vehicle demands significantly more kinetic energy than sustaining existing momentum, preserving rolling motion limits waste.
| Vehicle Model | Powertrain | Total Distance | Efficiency Metric |
|---|---|---|---|
| Skoda Superb | 2.0 TDI Diesel | 2,831 km | 2.6 L / 100 km |
| Audi A6 Sportback e-tron Performance | Electric Battery | 1,338 km | Single Charge |
| Plug-in Hybrid Model | PHEV (Zakopanem to Kraków) | ~112 km | 1.0 L / 100 km (First 90 km EV) |
Highway Velocities and Mechanical Drag Factors
On high-speed corridors and motorways, aggressive driving often yields negligible time gains when traffic density is high. Constant acceleration followed by heavy braking degrades brake components and spikes fuel consumption. Marczyk suggests stabilizing speeds between 100 km/h and 120 km/h using cruise control to optimize transit time and energy expenditure.
Beyond driving style, secondary physical variables dictate efficiency. Sub-optimal tire pressure increases rolling resistance, forcing the powertrain to draw more energy. Similarly, carrying unnecessary payload weight elevates the baseline energy required to move the chassis. When applied comprehensively, these adjustments can drop urban fuel consumption profiles from 9 liters down to 7 or 7.5 liters per 100 kilometers.
Technical Realities of Coasting and Hybrid Efficiency
Debates surrounding fuel conservation often center on coasting in neutral versus remaining in gear. Marczyk clarifies that modern automatic transmissions manage this efficiently, while manual gearboxes require contextual judgment based on terrain. When decelerating down a grade, leaving the vehicle in gear drops fuel consumption close to zero while utilizing engine braking to assist deceleration.
In a separate plug-in hybrid test running from Zakopanem to Kraków, Marczyk utilized pure electric propulsion for the initial 90 kilometers, followed by twenty-some kilometers on the combustion engine, yielding an average consumption of 1 liter per 100 kilometers. But the balance sheet tells a different story: these figures serve primarily as demonstrations of technical capacity rather than standard daily expectations.
“These records are a curiosity. Nevertheless, I recommend all road users pay attention to consumption. Even when we are on the road and observing these numbers, we focus more on driving. Thanks to that, the journey can simply be easier,” Marczyk stated.
