SixBlock scores every route by fuel cost — using real terrain, vehicle weight, and road grade. See exactly what bad routing costs you. Most fleets cut 5–12% off fuel.
Fleet fuel savings — June 2026

The problem
Route planners optimize for time or distance — not fuel. A route with 300 m of climb can cost 40% more in fuel than a flat one covering the same stops. SixBlock prices the terrain.
How it works
Drop a day of origin → destination pairs into the free fleet report — or pipe them through our API from your dispatch system.
Every route is scored with USGS street-segment elevation, your vehicle's weight and MPG, and live road grade. No telematics required.
Get per-route fuel cost, savings vs. worst alternative, and a fleet-wide CSV. Drivers navigate the cheapest line in the SixBlock app.

The benchmarks
From the lot
Route4Me optimized for time and my trucks still bled gas on the hills. SixBlock finally put a dollar figure on it — I walked into the budget meeting with the CSV.
Amazon hands me the routes — the gas comes out of my margin. SixBlock paid for itself in the first week.
I knew some techs drove inefficient routes — I just couldn't prove it. Now I have per-route fuel data across 12 metros.

Questions
We combine USGS elevation at street-segment level with your vehicle's weight and MPG. In testing, estimates land within 10–15% of actual fuel receipts — and the hillier your terrain, the bigger the savings.
