The Best Way to Burn 100 Gallons of Gasoline Fast

The relationship between vehicle speed and fuel consumption is far more significant than many drivers realise, with faster speeds dramatically increasing gasoline usage. This effect is rooted in the physics of aerodynamic drag, which grows exponentially as velocity rises. Specifically, the power required to overcome drag increases with the cube of the vehicle’s speed, meaning that driving at 70 mph consumes substantially more fuel than driving at 60 mph, and the jump from 60 to 50 mph is similarly impactful compared to 50 to 40 mph. The article highlights how this principle applies not only to petrol vehicles but also to electric cars, where higher speeds rapidly deplete battery reserves. Early electric vehicle owners, particularly those who navigated the limited charging infrastructure of a decade ago, experienced firsthand how driving speed affected range. The author recounts personal experience with a 2015 Tesla Model S on the German Autobahn, noting how driving at high speeds caused the estimated remaining battery capacity to plummet alarmingly fast. This real-world example underscores the practical importance of moderating speed to conserve energy, whether using gasoline or electricity. It also illustrates how modern EVs provide dynamic feedback on energy consumption, helping drivers adjust their behaviour to extend range. The article advises motorists to drive slower as the most effective way to reduce fuel or electricity consumption. While slowing down below speed limits on low-speed roads offers some savings, the most substantial benefits come from avoiding high speeds on highways and motorways. Staying within or below speed limits, particularly avoiding excessive speeds over 50 mph, can significantly reduce fuel burn and save money. This advice is especially pertinent given the current high cost of gasoline, which averages around $4.43 per gallon in the United States, though the principle applies universally. Ultimately, the piece serves as a reminder that aggressive driving habits not only increase fuel costs but also accelerate resource depletion and environmental impact. For those seeking to minimise expenses or extend electric vehicle range, maintaining moderate speeds is a straightforward and effective strategy. The article closes with a tongue-in-cheek note that if the goal is to consume fuel rapidly, then driving fast on highways is the surest way to do so, but for most, slowing down is the smarter choice.
