Electric convertibles are still rare, but several manufacturers now offer them or have announced models coming to market
An electric convertible is a car with a retractable or removable roof powered by a battery and electric motor instead of a gasoline engine. The main difference from a traditional convertible is that the electric drivetrain produces no tailpipe emissions and typically costs less to fuel and maintain. However, electric convertibles cost significantly more upfront than gas versions of the same model, and the battery adds weight that affects handling and range.
As of 2024, the convertible market is dominated by gas engines. Tesla has no convertible model. BMW offers the i8 Roadster (a plug-in hybrid, not fully electric), and Porsche sells the Taycan Cross Turismo with a removable roof panel, though it is not a traditional convertible. Mini Cooper SE has a hardtop convertible variant in some markets. The most accessible fully electric convertible currently sold in the United States is the Fiat 500e, which has a soft-top roof and starts around $34,000 before incentives. Volkswagen has shown concept convertibles but has not released a production model in the U.S. market yet.
Key Takeaways
- Electric convertibles weigh more than gas versions because of the battery pack, which reduces range and acceleration compared to closed-body electric cars.
- The Fiat 500e is the most widely available electric convertible in the U.S., with a range of roughly 150 to 190 miles per charge depending on driving conditions.
- Charging time at home on a standard outlet takes 24 to 48 hours for a full charge; a Level 2 charger cuts that to 6 to 8 hours.
- Electric convertibles may have access to for the federal tax credit of up to $7,500 if they meet price and income limits, though some models may phase out of may be able to access.
- Insurance, registration, and maintenance costs are typically lower for electric convertibles than gas convertibles, but repair shops that service electric vehicles are not yet available everywhere.
Why convertible design complicates electric powertrains
A convertible roof takes up space and adds weight. In a gas car, the engine sits under the hood and the fuel tank is compact, so the roof mechanism does not compete for battery space. In an electric car, the battery pack runs along the floor of the vehicle, and a retractable roof mechanism must fit around or above it. This constraint means electric convertibles either have smaller batteries than their closed-body counterparts, or they are heavier overall.
Weight is the enemy of electric range. A heavier car burns more energy to accelerate and maintain speed. The Fiat 500e convertible has an EPA-estimated range of 149 to 190 miles, depending on trim and driving conditions. A closed-body Fiat 500e can reach 200 to 242 miles on the same battery. The difference is roughly 30 to 50 miles of range lost to the convertible design and its structural reinforcements.
Aerodynamics also matter. A convertible with the roof down creates more wind resistance than a closed car, which further reduces range during highway driving. Manufacturers do not always publish separate range estimates for roof-up versus roof-down driving, so real-world range can vary more than the EPA estimate suggests.
Current electric convertible models and their specifications
The Fiat 500e is the entry point for most U.S. buyers. It is a small city car with a soft-top convertible roof, available in two battery sizes: a 42 kWh version with 149-mile range and a 58 kWh version with 190-mile range. Prices start around $34,000 for the base model before the federal tax credit. The car seats four and has minimal cargo space with the roof up.
The BMW i8 Roadster is a plug-in hybrid, not fully electric, so it carries a gas engine as backup. It has a 11.6 kWh battery that provides roughly 18 miles of electric-only range, then switches to the gas engine. It costs around $163,000 and appeals to buyers who want electric driving for short trips but do not want to worry about charging on longer journeys. It is not a true electric convertible.
The Mini Cooper SE Convertible is sold in Europe and some other markets but is not currently available in the United States. It has a 32 kWh battery with roughly 114 miles of range and a retractable soft top. Volkswagen has shown the ID. Cabriolet concept but has not confirmed a U.S. release date or price.
Porsche, Mercedes, and Audi have announced electric convertible concepts, but none are in production for the U.S. market as of early 2024. The convertible segment remains small, and manufacturers are prioritizing sedans and SUVs where volume is higher.
Charging times and infrastructure for electric convertibles
Charging an electric convertible depends on the charger type and battery size. A Level 1 charger (standard 120-volt household outlet) adds roughly 2 to 3 miles of range per hour, so a full charge of a 58 kWh battery takes 24 to 48 hours. Most owners do not use Level 1 for daily charging because the time commitment is too high.
A Level 2 charger (240-volt, installed at home or at public stations) adds 10 to 30 miles of range per hour, depending on the charger's power output. A 58 kWh battery typically charges fully in 6 to 8 hours on a Level 2 charger. Installation at home costs $500 to $2,500 depending on your electrical panel and wiring. Some states and utilities offer rebates that cover part of this cost.
DC fast charging (available at public stations) can add 150 to 200 miles in 20 to 30 minutes, but it is slower for electric convertibles than for heavier electric SUVs because the smaller battery fills more quickly and then tapers to protect battery health. The Fiat 500e can charge from 10% to 80% in roughly 35 minutes on a 50 kW fast charger.
Public charging networks like Electrify America, EVgo, and ChargePoint have thousands of stations across the U.S., but availability varies by region. Rural areas have fewer options. Most owners charge at home overnight and use public chargers only for longer trips.
Purchase price and federal tax credit may be able to access
Electric convertibles cost more upfront than their gas equivalents. The Fiat 500e convertible starts around $34,000, while a gas-powered Fiat 500 convertible costs roughly $28,000 to $30,000. That $4,000 to $6,000 premium reflects the battery and electric motor.
The federal tax credit of up to $7,500 can offset some of this cost, but may be able to access depends on the vehicle's final assembly location, battery component sourcing, and your household income. As of 2024, the Fiat 500e qualifies for the full $7,500 credit if your household income is below $300,000 (married filing jointly) or $150,000 (single). The credit is applied when you file taxes, not at the point of sale, though some dealers offer point-of-sale credit through a third-party lender.
Some states offer additional rebates. California, for example, provides up to $2,500 for used electric vehicles and has offered rebates for new purchases in the past, though the program structure changes year to year. Check your state's environmental or energy office for current offers.
Financing terms for electric convertibles are the same as for any car: typical auto loans run 36 to 72 months at interest rates that depend on your credit score and the lender. Lease options are available for some models, though leasing an electric car can be advantageous because battery degradation is covered under warranty.
Operating costs: fuel, maintenance, and insurance
Electricity costs roughly one-third to one-half as much as gasoline per mile. If you charge at home on a residential rate of $0.14 per kilowatt-hour (the U.S. average), charging a 58 kWh battery costs roughly $8, and that battery provides 190 miles of range. That works out to about $0.04 per mile. A gas convertible averaging 25 miles per gallon at $3.50 per gallon costs roughly $0.14 per mile. Over 10,000 miles per year, the fuel savings are around $1,000 annually.
Maintenance costs are lower because electric cars have no oil changes, spark plugs, transmission fluid, or timing belts. Brake pads last longer because regenerative braking (using the motor to slow the car) does most of the stopping work. Tire wear is higher due to the weight of the battery, so tire replacement costs may offset some maintenance savings. Warranty coverage on the battery typically lasts 8 years or 100,000 miles, and battery replacement outside warranty can cost $5,000 to $15,000 depending on the model.
Insurance rates for electric convertibles are comparable to gas convertibles of similar value, though some insurers charge slightly more because repair shops that service electric vehicles are less common in some areas. Collision and comprehensive coverage are standard; some insurers offer discounts for vehicles with safety features like automatic emergency braking.
Range, weather, and real-world driving conditions
EPA range estimates assume a mix of highway and city driving under moderate conditions. Real-world range varies based on temperature, driving style, and terrain. Cold weather reduces range by 20% to 40% because the battery is less efficient and cabin heating draws power. Highway driving at 70 mph reduces range more than city driving because aerodynamic drag increases with speed. Driving a convertible with the roof down further reduces range due to increased wind resistance.
A Fiat 500e rated at 190 miles might deliver 150 miles in winter highway driving with the roof down, or 210 miles in mild weather on city streets. Drivers who live in cold climates or take frequent highway trips should account for this variability when deciding whether an electric convertible fits their needs.
Regenerative braking helps extend range by converting the energy normally lost during braking back into the battery. Most electric cars allow drivers to adjust the strength of regenerative braking, and some convertibles offer a one-pedal driving mode where lifting off the accelerator slows the car significantly without touching the brake pedal.
Frequently Asked Questions
Can you drive an electric convertible with the roof down in the rain?
Yes, the electrical systems in electric convertibles are sealed and waterproof. Driving with the roof down in light rain is safe. Heavy rain or driving through deep water is not recommended for any car, electric or gas, because water can enter the cabin and damage interior components.
How long does an electric convertible battery last?
Most manufacturers warranty the battery for 8 years or 100,000 to 120,000 miles. Real-world degradation is typically 2% to 3% per year, so a battery retains roughly 80% of its capacity after 8 years. Batteries can last 15 to 20 years or longer, but replacement outside warranty is expensive.
Is an electric convertible safe in a crash?
Electric convertibles undergo the same crash testing as gas convertibles. The battery pack is mounted low in the floor and is protected by reinforced underbody panels. Convertibles are generally less rigid than closed cars, which is true for both electric and gas models. Safety depends more on the specific model's crash test ratings than on whether it is electric.
Can you tow a trailer with an electric convertible?
Most electric convertibles are not designed for towing. The Fiat 500e, for example, has no towing capacity. Towing significantly reduces range because it increases weight and aerodynamic drag. If towing is important to you, an electric SUV or truck is a better choice than a convertible.
What happens to an electric convertible battery in very hot weather?
Batteries perform less efficiently in extreme heat, and range can drop by 10% to 20% in very hot climates. Most electric cars have battery thermal management systems that cool the battery during charging and driving to prevent overheating. Parking in shade and avoiding fast charging in extreme heat helps preserve battery health.
