Electric convertibles exist, but your choices are limited and expensive

An electric convertible is a car with a retractable or removable roof powered by a battery instead of a gas engine. As of now, only a handful of manufacturers make them, and they cost significantly more than their gas-powered equivalents. The main models currently available in the United States are the Tesla Roadster (starting around $250,000, though deliveries have been delayed), the Porsche Taycan Cross Turismo (which has a removable roof panel, not a full convertible top), and the BMW i8 Roadster (production ended in 2020, available used only). A few other brands like Jaguar have announced electric convertibles for future release, but they are not yet on the market.

The reason convertibles lag behind in electrification is practical: a convertible body is heavier and less aerodynamic than a sedan, which reduces range. Removing the roof also removes structural rigidity, requiring engineers to reinforce the frame and battery pack. These changes add weight and cost, making electric convertibles a niche product for buyers who prioritize the open-air driving experience over efficiency or affordability.

Key Takeaways

  • Only three electric convertibles are currently sold in the United States, and all are luxury vehicles priced above $100,000.
  • Electric convertibles have shorter driving range than comparable electric sedans because the open body design is heavier and less aerodynamic.
  • Charging infrastructure and battery degradation work the same way in convertibles as in any other electric car, so your charging options depend on your location and home setup, not the body style.
  • Used electric convertibles are extremely rare, and warranty coverage may be limited if you buy one that is no longer in production.

How range and weight affect convertible performance

An electric convertible loses range compared to an electric sedan with the same battery size. The Tesla Roadster, for example, is rated for up to 620 miles of range, but that figure assumes ideal conditions and a fully charged battery. In real-world driving, most owners see 20 to 30 percent less than the EPA estimate, depending on weather, highway versus city driving, and how hard you accelerate. A convertible's open structure requires a reinforced frame and heavier battery pack to maintain safety, which means more weight to move and more energy consumed per mile.

The aerodynamic penalty is also real. When the roof is down, wind resistance increases, which drains the battery faster at highway speeds. If you plan to drive with the top down frequently, expect your actual range to drop by 10 to 15 percent compared to driving with the roof closed. This matters most on long trips where you need to plan charging stops carefully.

Charging and battery maintenance are the same as other electric cars

Charging an electric convertible works exactly like charging any other electric vehicle. You can use a Level 1 charger (a standard 120-volt household outlet, which takes 24 to 48 hours for a full charge), a Level 2 charger (240 volts, typically installed at home or found at public charging stations, taking 4 to 10 hours), or a DC fast charger (which can add 200 miles in 20 to 30 minutes). The convertible body does not change how the battery stores energy or how quickly it can accept a charge.

Battery degradation also follows the same pattern as other electric cars. Most manufacturers warranty the battery for 8 years or 100,000 miles, whichever comes first, and may provide that it will retain at least 70 percent of its capacity. The convertible's reinforced structure does not make the battery degrade faster. However, because so few electric convertibles are on the road, long-term data on battery life beyond 10 years is limited, so buying a used model is a higher-risk decision than buying a used Tesla Model 3 or Chevy Bolt.

Cost and availability in the used market

New electric convertibles are expensive. The Tesla Roadster starts at around $250,000, though Elon Musk has delayed deliveries multiple times since the car was announced in 2017. The BMW i8 Roadster, which was discontinued in 2020, sold for around $160,000 when new. The Porsche Taycan Cross Turismo, which has a removable roof panel rather than a full convertible top, starts around $90,000. For comparison, a new Tesla Model 3 starts around $40,000, and a new Chevy Bolt EV starts around $27,000.

The used market for electric convertibles is extremely thin. Because so few were made, you will struggle to find one for sale in your area, and prices do not drop as steeply as they do for used sedans. A used BMW i8 Roadster from 2019 might still cost $80,000 to $100,000. If you buy a used model from a brand that has stopped production (like the BMW i8), you will have limited access to warranty coverage and may face higher repair costs if the battery or electric motor fails.

Weather and maintenance considerations for the convertible top

The convertible top mechanism itself is electric in most modern convertibles, including the Tesla Roadster. This means the motor that raises and lowers the roof draws power from the main battery, though the amount is negligible—typically less than 1 percent of your total charge per use. The mechanism is sealed and does not require special maintenance beyond keeping the seals clean and dry to prevent water leaks.

In cold weather, the battery's range decreases by 20 to 40 percent, the same as any electric car. Driving with the top down in winter also increases wind resistance and heat loss, which compounds the range penalty. If you live in a cold climate and plan to use the convertible top frequently, budget for significantly shorter driving range during winter months.

Environmental impact compared to gas convertibles

An electric convertible produces zero tailpipe emissions, which means no carbon dioxide, nitrogen oxides, or particulate matter while driving. However, the environmental benefit depends on how the electricity is generated in your region. If your power grid relies heavily on coal or natural gas, the emissions are lower than a gas car but not zero. If your grid uses mostly renewable energy or nuclear power, the emissions benefit is much larger. Over the car's lifetime, an electric convertible typically produces 50 to 70 percent fewer emissions than a comparable gas convertible, even accounting for battery manufacturing and electricity generation.

The battery itself is recyclable. Lithium, cobalt, and nickel can be recovered and reused, though the recycling industry is still developing. Most manufacturers now take back old batteries and either refurbish them for second-life use (like stationary energy storage) or send them to recyclers. This is better than the alternative—a gas car's fuel tank and engine cannot be recycled in the same way.

Alternatives if you want an electric car with open-air driving

If you want an electric car with an open-air experience but do not want to pay convertible prices, consider an electric targa-top car like the Porsche Taycan Cross Turismo, which has a removable roof panel. You get some of the open-air feeling without the full convertible mechanism, and the structural integrity is better. Alternatively, some electric SUVs and crossovers have panoramic sunroofs that open partially, which provides ventilation and light without the full convertible experience.

If you are willing to wait, Jaguar has announced an electric convertible for 2025 or 2026, though pricing and availability have not been confirmed. Aston Martin has also shown concept images of an electric convertible, but no production timeline has been announced. If you are not in a hurry to buy, monitoring these announcements may give you more options and potentially lower prices as competition increases.

Frequently Asked Questions

Does the convertible top drain the battery faster?

The motor that opens and closes the top uses a small amount of power, but it is negligible—less than 1 percent per cycle. The real drain comes from driving with the top down, which increases wind resistance and reduces aerodynamic efficiency. Expect 10 to 15 percent lower range when driving with the roof open on the highway.

Can I charge an electric convertible in the rain?

Yes. All electric car charging equipment is weatherproof and designed to be used in rain, snow, and wet conditions. The charging port and connector are sealed, and the electrical system is insulated. There is no safety risk to charging in wet weather.

What happens to the battery if water gets into the convertible?

The battery pack is sealed and located under the floor of the car, protected by multiple layers of insulation and waterproofing. Water entering the cabin through the convertible top will not reach the battery. However, if the roof seals wear out and water leaks persistently, you should have them inspected and replaced to prevent interior damage and mold.

Is an electric convertible better for the environment than a gas convertible?

Yes, significantly. An electric convertible produces zero tailpipe emissions and typically generates 50 to 70 percent fewer total emissions over its lifetime than a gas convertible, even accounting for battery manufacturing and electricity generation. The exact benefit depends on your region's power grid mix.

Can I tow a trailer with an electric convertible?

Most electric convertibles are not rated for towing. The Tesla Roadster, for example, has no towing capacity. If towing is important to you, an electric SUV or truck is a better choice. Towing significantly reduces range in any electric vehicle because of the extra weight and wind resistance.
