European Rally Champion Miko Marczyk has just rewritten the rulebook on fuel efficiency. Known for pushing cars to their limits on gravel and tarmac, the Polish driver proved he can also push the limits of a diesel tank, covering an astonishing 2,831 kilometers (1,759 miles) from Poland to Paris and back without refueling once.
A Rally Driver’s Unexpected Feat
Marczyk, who usually dominates European rally stages in his Skoda Fabia RS Rally2, took on a completely different kind of challenge: testing the endurance of a near-stock Skoda Superb 2.0 TDI. The goal? To see just how far one tank of diesel could really go in the real world.
The result was nothing short of record-breaking. Averaging 2.61 liters per 100 kilometers, equivalent to 108.2 miles per gallon (mpg), Marczyk officially set a world record for the greatest distance driven on a single tank of fuel.
The Car: Almost Straight from the Factory
What makes this feat more impressive is that the Superb used for the journey was virtually untouched from its factory configuration. The only modifications were Sportline suspension springs to slightly lower the car and low rolling-resistance tyres to cut friction.
Otherwise, everything from the engine tuning to the fuel used remained standard. In fact, Marczyk completed the entire journey on regular-grade diesel, not the premium variant many eco-drivers rely on for efficiency gains.
The Preparation: Precision Over Speed
Before the record attempt, Marczyk spent months learning the car’s behavior. He logged over 20,000 kilometers (12,427 miles) in four months, experimenting with driving techniques, tyre pressures, and speed consistency.
His biggest insight: 80 km/h (50 mph) is the sweet spot. At that speed, the 2.0-litre TDI engine operates at peak efficiency. “I found that maintaining steady speed, anticipating traffic, and avoiding unnecessary braking made a huge difference,” he said.
He also made use of the Superb’s Eco mode, which softens throttle response and ensures smoother, more economical gear changes.
Mastering the Elements
Even with meticulous preparation, conditions weren’t always ideal. “Germany was a bit challenging,” Marczyk admitted. “Night temperatures dropped to around one degree Celsius, which isn’t great for fuel economy. There were also long uphill sections, some over five kilometers, which raised consumption.”
Still, smart tactics helped offset the losses. Marczyk kept optimal tyre pressures, chose routes with favorable wind conditions, and occasionally benefitted from aerodynamic drafting behind trucks, though always at a safe distance.
Beyond the Record: What’s Next
Despite nearly doubling Skoda’s official WLTP fuel efficiency figures, Marczyk believes there’s more to achieve. “I’m confident I could cross the 3,000-kilometer mark with better weather and premium fuel,” he said.
His run isn’t just a stunt; it’s a reminder that even performance drivers can champion sustainability. For Skoda, it’s a powerful testament to the engineering behind its latest diesel models, proving efficiency and endurance can coexist.
From rally stages to record books, Miko Marczyk has shown that skill behind the wheel isn’t just about speed; it’s about control, consistency, and understanding every drop of fuel.
