We drove our 2024 BMW iX xDrive50 from Birmingham through the Smokies to the BMW Performance Center in Spartanburg — without stopping to charge once. The EPA said 324 miles. We did 390. Here's how it went.
The trip had two destinations and one goal. First, Pigeon Forge — the Smokies, a couple of nights in the mountains, the kind of Tennessee road trip that Southerners have been making for generations. Second, the BMW Performance Center in Spartanburg, South Carolina — the only BMW M driving school on the East Coast, sitting in the shadow of the Blue Ridge Mountains just across the street from BMW's only U.S. manufacturing plant. We were booked into the M School for a full day on track.
We planned the whole thing around one charging stop. When you're driving a vehicle rated for 324 miles EPA and the full route is pushing 390, you build in a buffer — that's just how you think about EV road trips after long enough. We picked out an Electrify America station in Chattanooga as our safety net. We never touched it.
The iX had other plans. Good ones.
We left Birmingham before sunrise with the iX charged to 100% — about 330 miles of indicated range on the dash. The route north is one of the better Southern interstate drives: I-59 cuts through the rolling terrain of northeast Alabama, hits Chattanooga with its familiar skyline drama on I-24, then picks up I-75 north into Tennessee and the long run toward Knoxville. Total distance to Pigeon Forge from Birmingham is right around 291 miles depending on which exit you take off I-75.
The iX in this kind of driving — steady interstate cruise, moderate grades, light traffic in the predawn hours — is at its absolute best. The adaptive air suspension soaks up Alabama and Tennessee highway surfaces without a second thought. The cabin is library-quiet at 75 mph. The Bowers & Wilkins audio system, running through the Blue Ridge foothills as the sun came up over Chattanooga, is one of those experiences that makes the case for the car better than any spec sheet could.
We watched the range carefully through Chattanooga — the planned stop at Electrify America stayed planned and nothing more. The regenerative braking on the Tennessee grades was doing its quiet work, adding back small increments on every descent. By the time we reached the Knoxville area, we were running noticeably more efficient than the navigation had predicted at departure. We took the I-40 east exit toward Sevierville and SR-66, and rolled into Pigeon Forge with more range than expected.
Pigeon Forge has Level 2 charging available at several hotels along the Parkway — worth confirming at booking if you're staying overnight. We topped up overnight at the hotel using their Level 2 charger. The iX adds roughly 27 miles of range per hour on a 240V circuit, so an overnight charge fully replenishes whatever you used on the drive up. We departed Pigeon Forge the next morning at 100% for the run south to Spartanburg.
Pigeon Forge doesn't need much introduction for Southern road trippers — it's one of those places that's simultaneously exactly what you expect and still worth the trip. The strip along the Parkway has its own particular energy: Dollywood in the distance, the outlet malls, the pancake houses that have been there since before most of their current customers were born. We had dinner at one of the Old Mill restaurants on the river in nearby Pigeon River. It was perfect.
What Pigeon Forge also is, for EV drivers specifically, is a natural overnight stop on a longer route through the Southeast. The mountain geography that makes it attractive for tourists also makes it range-friendly on the approach — descending grades add back energy, and the lower speeds through the Sevier County traffic give the regenerative system time to work. If you're running an EV route between Alabama and the Carolinas, Pigeon Forge as an overnight isn't a compromise. It's a destination.
The second leg was the shorter one — roughly 99 miles from Pigeon Forge south through the mountains on I-40 east, picking up I-26 west into the Greenville-Spartanburg area. It is, without exaggeration, one of the best stretches of interstate driving in the American Southeast. The climb out of the Tennessee Valley through the Appalachians on I-40 near the North Carolina border, then the long descent through Asheville and down into the Upstate — in an iX, at legal speeds, on a clear morning, is a drive worth making for its own sake.
The regenerative braking on the mountain descents was doing serious work. The energy recovered on the I-40 grades between Knoxville and Asheville was measurable and meaningful. By the time we reached the BMW Performance Center in Greer — technically between Greenville and Spartanburg, just off I-85 — we had covered 390 total miles from Birmingham on the original charge, with range to spare on the dash.
Three hundred and twenty-four miles is the EPA number. Three hundred and ninety is what we got. That's a 20 percent improvement, and it didn't happen by accident or by driving like we were trying to conserve fuel. We drove at normal highway speeds throughout. Here's what made the difference.
Early morning temperatures. Departing Birmingham before dawn meant cooler ambient temps for most of the first leg, which keeps EV battery chemistry in its sweet spot. Heat is the enemy of range; the pre-dawn departure helped more than we planned.
Mountain grades working in our favor. The I-40 corridor through Appalachia is a range recovery machine for EVs. Every mile descending from the Tennessee Divide and again from the North Carolina mountains puts energy back in the pack through regenerative braking. A route that looks punishing on a range calculator often outperforms expectations in practice because the calculator doesn't fully model regen recovery on long descents.
Steady interstate speeds. The iX is most efficient in exactly this kind of driving: sustained 65–75 mph cruise on a highway with moderate grades. It's not a stop-and-go city car. This trip played to every efficiency strength the platform has.
Birmingham to Spartanburg via Pigeon Forge is approximately 390 miles. The 2024 BMW iX xDrive50 handles this in a single charge under normal driving conditions, with the mountain regen on I-40 working substantially in your favor. If you're in a different EV with less than 350 miles of real-world range, plan a 20–30 minute Electrify America stop in Chattanooga (exit 4, I-24) or use the Tesla Supercharger in Knoxville if you're in a NACS-compatible vehicle. Don't skip the overnight in Pigeon Forge — the Level 2 hotel charging is free at most properties and completely restores the battery by morning.
The BMW Performance Center sits in Greer, South Carolina, just outside Spartanburg — about three exits off I-85, next door to BMW's only U.S. manufacturing plant where they build the X3, X4, X5, X6, and X7. The facility is also home to the only BMW M driving school on the East Coast, and it has been since BMW planted its flag in the Upstate in the early 1990s.
The M School is what we came for. A full day on track in M vehicles — M3, M4, M2, depending on availability — working through the fundamentals of high-performance driving with BMW-certified instructors. Cornering lines, brake points, high-speed stability, the skid pad. The track at Spartanburg has fast corners, a proper back straight for speed exercises, and a polished wet concrete skid pad that teaches oversteer and understeer correction in a controlled environment. It is, plainly, one of the best days you can spend in a car anywhere in the Southeast.
There's also the BMW Zentrum museum directly adjacent — the only BMW museum in North America, free admission, with a collection spanning from early motorcycles to current production M cars and concept vehicles. And the factory itself offers tours when available, where you can watch over 1,500 vehicles roll off the line each day. Budget a full day on each end of the driving school if you can.
The number that sticks with us from this trip isn't 390 miles, though that's the headline. It's the confidence. After two-plus years of owning the iX, we planned a charge stop on a route that asked more than the EPA rating and drove the whole thing without needing it. That confidence — knowing the car will handle what you ask of it — is what separates an EV you enjoy from an EV you manage.
The route from Birmingham through the Smokies to Spartanburg is one of the best road trips the South offers. Chattanooga in the rearview. Appalachian grades through North Carolina. Pigeon Forge in the middle. The BMW Performance Center at the end. Doing it in an EV with 390 miles of real-world range, zero charge stops, and a cabin that makes every mile enjoyable isn't just viable — it's the ideal way to do it.
If you're sitting on the fence about whether an EV can handle a serious Southern road trip, this is your answer. It can. Plan the stops, trust the regen on the mountains, and charge overnight wherever you're staying. The infrastructure is there. The range is there. Go.
