Eight towns, twelve corridors. Line weight is trip count, so the thick line is the one that pays for itself. Orange rings mark places the car has actually charged. The four corridors beyond the map, from the road trip, are in the table below.

Case study: a weekend road trip

Home-charged daily driving is where this car's cost advantage is clear and consistent. A genuine road trip changes that math. Take a common trip from this area: Nashville to Gulf Shores, AL, a well-worn weekend and vacation drive, roughly 460 miles one way from the Brentwood area, most of it on I-65 South, then I-10 East, then local parkways into Gulf Shores and Orange Beach. A real source puts the Nashville-anchored version of this drive at about 470 miles and a little over 7 hours of driving; starting from Brentwood, a few miles closer to the interstate, trims that slightly.

Charging stops: the real math

This car's comfortable real-world range between fast-charging stops, running a 20–80% pattern, lands somewhere around 250–270 miles at highway speed. A 460-mile leg needs roughly two Supercharging stops each way, about 25–35 minutes apiece for a 20–80% top-up on this platform. The route has real coverage the whole way: Superchargers exist along I-65 in Athens and Huntsville near the state line, Birmingham further south, and a Supercharger sits at The Wharf in Orange Beach, right at the destination. The car's own trip planner would pick the actual two stops from stations like these rather than this being a fixed, pre-mapped route.

Time: this trip against a comparable gas car

Door to door, that's roughly 7–7.5 hours of driving plus 50–70 minutes of charging, call it 8–8.5 hours total. A comparable gas car covers the same distance in the same 7–7.5 hours of driving plus one short fuel stop, 10–15 minutes. For a trip this length, the honest time cost of going electric is somewhere around 45 minutes to an hour, not nothing, but not the multi-hour ordeal it's sometimes made out to be either.

Cost: where the math actually flips

920 miles round trip at this car's real-world 300–360 Wh/mile works out to roughly 276–331 kWh. At this car's own real Supercharging rate of $0.56/kWh, that's roughly $155–185 for the whole round trip. Run the same 920 miles through the ES300h at 44 mpg and Tennessee's $3.64/gallon average, and gas comes to about $76. Through the gas-only ES350 at 25 mpg, about $134. For a Supercharging-heavy long trip specifically, this car can cost more to run than either gas comparator, not less. That's the flip side of the home-charging advantage documented in What this car costs to run: the savings live at home, at the lower, off-peak rate. On the road, paying full Supercharging price for every mile, the advantage isn't guaranteed, and here it disappears entirely.

Case study: winter range

Everything above assumes mild-weather driving. Cold weather is real and worth accounting for honestly, using published data rather than guessing, since this car doesn't have a full winter of its own logged range data yet.

Recurrent's analysis of 30,000-plus real vehicles, using fleet telematics rather than a lab test, found EVs retain about 78% of maximum range at 32°F and roughly 70% at 20°F. The carmaker specifically is called out as one of the stronger performers in that data set, largely because of the Octovalve thermal system the carmaker introduced in the Model Y in 2021, which this 2024 car has. That means these percentages are closer to a conservative floor for this specific car than a precise prediction: it likely does somewhat better than the fleet-wide average, not worse.

ConditionRange retainedApplied to this car's 310-mi EPA rating
Mild weather (baseline)100%310 mi
~32°F~78%~242 mi
~20°F~70%~217 mi

Against an 82-mile round trip, even the 20°F figure leaves a wide margin; cold weather doesn't meaningfully threaten a drive this short. It matters more on the road trip case study above: at 217–242 miles of cold-weather range instead of the 250–270-mile mild-weather estimate used there, the same 460-mile leg would realistically need three to four Supercharging stops each way instead of two, adding real time to an already-longer winter drive.
