Hey everyone, if you’ve ever been eyeing an Extended Range Sedan (ER Sedan, for short) and thought, “Can I actually make this thing feel like my car?”—you’re in the right spot. As someone who’s been building and supplying these rides for over eight years, I get it. ER Sedans are such a solid middle ground between electric range anxiety and gas-powered freedom, but customization is where they stop being just a vehicle and start being yours. Let’s break this down without all the stuffy industry jargon, okay? Extended Range SEDAN

First off, let’s get one thing straight: when I started in this game back in 2015, the answer to “can you customize an ER Sedan” was mostly a shrug. Back then, most of these cars rolled off the line with three basic trim levels—no extra frills, no real choices beyond color and wheel size. But fast forward to 2024? Consumers don’t want one-size-fits-all, and let’s be real, how many people drive the exact same car as their neighbor down the street? We listened, we changed our whole setup, and now customization isn’t just an option—it’s part of the deal.
Let’s start with the stuff you touch every single day: the interior. This is where most people want to put their stamp, right? Back in the day, we only offered black or gray cloth seats (if you were lucky, tan leather). Now? Let’s talk real options. You want vegan suede seats with red stitching that matches your favorite baseball team’s colors? Done. Want heated and ventilated front seats and heated rear seats? Not a problem—we used to make you pick one or the other, but feedback from customers said that was garbage. Need a built-in car seat for your 2-year-old? Wait, no—we don’t do custom car seats, but we do offer pre-installed LATCH anchors with extra padding, and you can upgrade the rear cabin with fold-out tray tables, wireless charging pads for backseat passengers, and even a little cooler for your kids’ juice boxes or your work coffee. Oh, and the infotainment system? You used to have to stick to the 10-inch touchscreen we installed. Now we let you pick between a 12-inch screen with Apple CarPlay/Android Auto, or if you’re into things like off-road mode (wait, ER Sedans are mostly highway, but some people take them on dirt backroads—no judgment), we even add a custom performance display that shows your electric range and gas generator status in real time, right where you want it.
Next, the fun stuff that makes people do a double-take when they see your car on the road: exterior and performance tweaks. Let’s start with wheels. Back in 2016, all our ER Sedans came with 16-inch silver steel wheels. Now you can pick 17-inch alloy wheels in matte black, gunmetal gray, or even a limited-edition bronze that we did last year—super popular with people who like that rugged electric vibe. Tires too: if you drive in a place with tons of snow, we can swap the standard all-season tires for winter tires, no extra markup if you order it upfront. Now for the cool part—performance, without messing up the ER part. The whole point of an ER Sedan is that you don’t have to worry about running out of charge, so we didn’t want to mess with that range. But if you want a little extra oomph when you hit the gas? We offer a custom tuning package for the electric motor that bumps up horsepower by 15%—we tested it, and it only cuts your total range by like 3%, which is nothing compared to the extra power. And if you hate the standard silver paint job? We do more than just the basic 8 colors. You want matte navy blue, candy-apple red, or even a custom wrap with your favorite band’s logo? Wait, we don’t do full custom vinyl wraps on the assembly line (that’s more of a post-purchase thing anyway), but we do offer two exclusive metallic colors only for our customers who order custom. Last year, we had a guy from Texas who got a custom deep teal, and his wife picked a soft lavender—those aren’t sold anywhere else.
Wait, let’s talk about what people actually ask for, because I get tons of emails every week from customers with weird, specific requests. A few months back, a guy from Seattle emailed us saying he’s a freelance photographer, and he needed a spot to mount a camera rig on the roof without messing up the electric range. We worked with a local fabricator to make a custom low-profile roof rack that’s aerodynamic—tested it in a wind tunnel, and it only cuts range by 2% instead of the 10% the old bulky racks do. Another customer, a mom from Chicago, wanted extra safety features for her teen who’s borrowing the car. We added custom blind-spot monitors that beep extra loud, plus a speed limiter set to 80 mph—she said it made her way more comfortable letting her daughter drive it to college. And no, we don’t do weird stuff like adding flame decals or neon underglow (we draw the line at that, sorry), but if it’s functional and doesn’t make the car unsafe, we’ll figure it out.
Now, let’s get real about the fine print, because customization isn’t free or instant—let’s be honest. If you order a basic ER Sedan with standard trim, it’s $32,000. Add a custom interior package? That’s an extra $1,500. The performance tuning is $800. The custom exterior paint is $1,000. And you have to wait a little longer—standard cars take 2 weeks to ship out, custom orders take 4 to 6 weeks. Is that worth it? For 9 out of 10 people who order custom, yes. We had a customer in Miami who ordered his ER Sedan with bronze wheels, vegan brown interior, and the performance tune, and he told us it feels like “my car, not every other ER Sedan on the block.” That’s the whole point.
Wait, I should also bust a myth here: a lot of people think customizing will mess up the warranty. Nope. All the upgrades we do in-house are covered by our 5-year/60,000-mile warranty. If you go to a random shop and add something, that might void parts, but our custom stuff is installed by our certified techs, so no issues. We also offer a 30-day return window for the custom parts, if you decide you don’t like them. That was a big win for us—last year, a guy ordered the matte black wheels and decided he liked the silver better, so we swapped them for free, no questions.
Let me talk about a recent project that really stuck with me, because it showed how far we’ve come. A customer named Jake from Denver reached out, saying he’s a part-time wilderness guide, and he needed an ER Sedan that could handle both highway drives to his job and dirt roads to backcountry campsites. His main request: a way to charge his portable camping gear off the car’s battery, plus extra underbody protection for rough terrain. We didn’t have a ready-made solution, so our engineering team worked with him for two months. We added a 12V outlet in the trunk that can power a 300-watt cooler or a portable blender (his words, he’s a smoothie guy), and a custom aluminum skid plate under the engine. He picked the matte black wheels and off-road tires, and when we delivered it, he sent us a photo of him camped in the Rockies, the car parked next to his tent. That’s when I knew we weren’t just selling cars—we were building tools that fit your life.
Now, what about post-purchase customization? Let’s be clear: if you buy a standard ER Sedan and decide six months later you want to swap the seats or add a sound system, you can do that too. We sell official replacement parts on our website, so you don’t have to go to a third-party shop that might mess up the wiring. We also host quarterly meetups where customers show off their custom ER Sedans—last month, we had a guy with a custom sound system that bumps so loud, the rearview mirror shakes, and it was all done with official parts.
I get why some people are hesitant to customize. Maybe they think it’s too expensive, or too much hassle. But here’s the thing: an ER Sedan is a big investment, right? You’re not buying a phone that you’ll upgrade every two years—you’re driving this car for 10 years or more. Why not make it feel like yours? Whether you’re a photographer needing extra gear space, a parent needing a safe car for your kids, or just someone who hates the color options the factory gives, customization works.

Wait, let’s circle back to the start. When I first got into this business, I thought ER Sedans were just another vehicle, all the same. But over the years, I’ve met so many people who’ve made their cars work for their unique lives, and that’s where the magic is. Sure, the base model is great for commuting to work, but adding a few custom touches turns it into something that fits you, not just the average driver.
