Fuel, Charging and Range on a Road That Runs Out of Land

Treat the sections below as a sequence. With fuel and charging on remote coasts, getting the early decisions right makes the later ones much easier.

The map lies about distance

A coastal road follows every inlet, headland and river mouth, so the driving distance far exceeds the straight line. Average speeds are low because the road is narrow, sinuous and frequently shared with agricultural traffic and delivery lorries. That combination means a day's driving on a coast covers much less ground than the same hours inland.

Peninsulas make it worse, because a wrong turn or a missed stop means retracing the whole leg. Planning fuel and charging against time rather than distance is the adjustment that works.

Fuel stations are a rural service

Filling stations on remote coasts are often attached to a shop or a garage with ordinary business hours. Out of season some close entirely, and the nearest alternative may be a substantial detour inland.

With the tide out, card-only pumps that operate outside those hours are common but not universal, and they occasionally fail. Prices on remote coasts and islands are higher because delivery costs are higher, which is arithmetic rather than opportunism. The practical habit that works everywhere is to refill at half a tank rather than at a warning light.

Charging on a thin network

Charge point coverage along popular coasts has improved considerably, but remote sections remain sparse. Single units are common, which means one vehicle already plugged in doubles your waiting time.

Out of season, reliability varies between networks, and a unit shown as available on an app may turn out to be faulty when you arrive. Payment methods differ between networks and between countries, so more than one method is worth having. Checking live status before committing to a leg is the equivalent of the half tank rule for combustion vehicles.

What actually consumes range

Headwinds on an exposed coast are persistent rather than occasional and have a substantial effect on consumption. Coastal roads climb and descend constantly, and while descents recover some energy in an electric vehicle they do not recover it all.

Roof boxes, bikes and boards increase drag considerably at the speeds where drag dominates. Cold weather reduces battery range noticeably, and heating the cabin draws directly on the same battery.

Realistic planning uses the worst case rather than the manufacturer's figure, particularly for the last leg of a day.

Islands are their own case

Fuel on an island arrives by tanker on the ferry, and a single pump may serve the whole island on limited and seasonal hours. Charging infrastructure on islands can be minimal, and the grid itself may constrain how fast charging is allowed. Accommodation with a domestic socket is often the realistic charging plan rather than a public rapid unit.

Before the first ferry, ferries do not usually offer charging on the vehicle deck, and those decks are closed to passengers for the duration of the crossing. Arriving on an island with a nearly full tank or battery removes an entire category of problem.

Building the stops into the route

Plan refuelling and charging around meals and viewpoints rather than treating them as interruptions. Note the last reliable stop before a long and thinly served coastal section, and treat it as a decision point rather than an optional extra.

Along that stretch of coast, ask locally about opening hours out of season, because published information for rural stations is frequently out of date. Carry a means of paying that does not depend on a mobile signal, which is absent on many coastal roads. Doing this once at the start of a trip removes most of the anxiety from the rest of it.

The takeaway

Plan coastal fuel and charging against driving time, not map distance, and never pass the last reliable stop on a low tank.

Arrive a day early. A coastline rarely rewards a tight schedule.
