Tailwind Route Fuel Economy

The same road can cost you 10% more fuel — or 10% more battery — depending on nothing but the wind. Tailwind Drive reads the wind forecast along your entire route, hour by hour, and tells you the smartest time to leave.

ONE DESTINATION, EVERY DEPARTURE COMPARED
- Enter where you're going. Tailwind Drive samples the wind forecast along the actual driving route — not just at your house — matched to the time you'd pass each stretch
- A departure scanner compares every hour up to 48 hours ahead and highlights the windows with the least headwind and the calmest crosswind
- See the verdict in plain numbers: estimated energy impact for each departure time

MADE FOR EV DRIVERS
- Headwind quietly eats range; on gusty days the effect is real. Tailwind Drive turns the forecast into an estimated range impact for your EV
- Enter your rated range and see the estimate in kilometres or miles, not vague warnings
- Pick the departure window that might let you skip a charging stop on a long trip

CROSSWIND SAFETY FOR BIG VEHICLES
- Driving a camper, a van, towing a trailer, or carrying a roof box? Side wind is a stability issue, not just a fuel issue
- Tailwind Drive rates crosswind exposure segment by segment along your route, tuned to your vehicle profile
- Spot the risky stretches and hours before you're on the bridge fighting the wheel

SEE THE WIND ON THE MAP
- Your route is coloured stretch by stretch: green tailwind, red headwind, amber crosswind
- Wind arrows show direction and strength at each point, at the time you'd actually be there
- Segment list with head/tail/cross components, gusts and timing

YOUR VEHICLE, YOUR NUMBERS
- Profiles for EV, petrol car, SUV, van, camper/RV, car with trailer, motorcycle — each with its own aerodynamic sensitivity
- Units your way: km/h, mph, m/s or knots
- Save your regular trips and re-check the wind in two taps

PRIVATE BY DESIGN
- One-time purchase. No subscription, no ads, no account
- Your saved trips and vehicle profiles stay on your device
- To get the forecast, the coordinates along your route are sent to the Open-Meteo weather service — nothing else, no account, no tracking

Tailwind Drive uses Open-Meteo forecasts. Estimates are planning aids based on aerodynamic models — actual consumption varies with traffic, speed and terrain.
