How We Calculated These Costs
Our calculation uses the current average UK electric price of 28.0p per litre and an assumed fuel efficiency of 130 MPG for a typical electric car. Here's the step-by-step breakdown:
- Distance: 100 miles each way (200 miles return)
- Fuel needed (one way): 100 ÷ 130 = 0.77 UK gallons (3.5 litres)
- Cost (one way): 3.5 litres × 28.0p = £0.98
- Annual estimate: 2 one-way trips per week × 52 weeks = £102 per year
Understanding Your Road Trip Fuel Costs
A 100-mile road trip is a moderate journey, perfect for a day out or weekend away. Planning ahead helps you understand the true cost of your adventure beyond just the fuel.
Electric vs Other Fuel Types
Electric vehicles have the lowest per-mile running cost of any fuel type. While the upfront cost is higher, the savings on fuel (electricity vs petrol/diesel) are substantial. Home charging is significantly cheaper than public charging stations, and many workplaces now offer free charging.
Tips to Reduce Your Road Trip Fuel Costs
- Maintain a steady speed and avoid harsh acceleration — smooth driving can improve fuel efficiency by 15-20%
- Keep your tyres inflated to the recommended pressure — under-inflated tyres increase fuel consumption by up to 3%
- Remove unnecessary weight from your vehicle — every 50kg of extra weight increases fuel consumption by about 1-2%
- Use air conditioning sparingly — it can increase fuel consumption by up to 10% in urban driving
- Plan your route to avoid congestion — stop-start traffic significantly increases fuel use
