As fossil fuel vehicles are gradually phased out and electric vehicles become increasingly popular, more users face a crossroads: Should I buy a new electric vehicle or convert my existing gasoline car to electric?
Most people are familiar with buying new EVs. However, as electrification technology matures and global conversion regulations ease, EV conversion is rapidly emerging as a cost-effective, sustainable alternative, sparking worldwide attention and discussion.
This article comprehensively compares "conversion vs. new vehicle purchase" from aspects of cost, compatibility, environmental impact, and regulatory feasibility, helping you determine which option is more economical and suitable for you.
EV Conversion vs New EV Purchase: What Do They Mean?
EV Conversion
Refers to converting a traditional internal combustion engine vehicle to pure electric drive by replacing core components such as the motor, battery system, and electronic control unit.
- Lower total cost (only replacing core systems)
- Ideal for users who love their old cars, are budget-sensitive, and value practicality
- Fast timeline: 7 days to 3 weeks
- High customization with multiple configuration options
- Road legal after certification
New EV Purchase
Refers to directly purchasing factory-manufactured pure electric or plug-in hybrid vehicles, enjoying full vehicle warranty, integrated smart systems, OTA updates, and other benefits.
- Higher upfront purchase cost
- Ideal for users pursuing brands, appearance, and smart tech experiences
- Medium timeline: 3-6 weeks (including registration)
- Medium customization depending on model configuration
- Compliant from factory
Cost Showdown: Which Is More Wallet-Friendly?
Cost is the most critical factor in decision-making. Using CMVTE standard EV kit data for comparison:
Conversion Cost Estimate (Compact Car Example)
Cost Components
- Drive system: CMVTE 50kW motor + controller = $2,850
- Battery pack: 96V/144V lithium-ion system ≈ $1,750-2,850
- BMS + CAN bus module: $450
- Wiring harness, motor mounts, labor: $750-1,050
- Compliance testing & certification: $150-450
New EV Purchase Cost Estimate (Mainstream A0/A-Class Car Example)
Cost Components
- Vehicle price: $17,500-32,000
- Taxes + insurance: $1,500-3,000
- Charger installation, etc.: $450-1,200
Conclusion: The initial investment for conversion is 1/3 (or less) of purchasing a new EV, making it ideal for budget-conscious users or those not ready to replace their vehicles.
Compatibility & Customization: Flexibility vs. Intelligence?
Ideal Conversion Scenarios
- Owners unwilling to scrap beloved classic cars
- Commercial fleets and logistics companies converting existing ICE vehicles
- Special vehicles requiring customized solutions (e.g., RVs, minibuses)
CMVTE offers 50kW, 70kW, 100kW standardized kits compatible with: Toyota Corolla, Nissan Sylphy, Volkswagen Polo, Buick GL8, Wuling Hongguang
Ideal New EV Buyers
- Those pursuing cutting-edge technology (autonomous driving, voice control)
- Those needing complete factory warranty and service networks
Summary: Conversion offers superior customization, especially for users emotionally attached to their vehicle's appearance or layout.
Environmental Impact: Conversion Enables Truly Low-Carbon Mobility
While new EVs produce "zero tailpipe emissions," their carbon footprint during manufacturing isn't zero. EV conversion reuses chassis and existing components, significantly reducing waste.
According to EU Life Cycle Assessment reports:
- Compared to buying new, EV conversion reduces manufacturing process CO2 emissions by approximately 45%
Countries with strict environmental regulations (UK, France, Germany) actively promote conversion as part of green policies.
Regulations & Legality: Road Legality Cannot Be Compromised
The regulatory framework for EV conversion is rapidly developing:
- UK: DVLA allows certified converted EVs to be registered and receive green license plates
- France: Government offers conversion subsidy programs
- Germany: Clear registration guidelines and inspection standards
- China: Pilot cities allow "fuel-to-electric" conversion registration and new energy license plates
CMVTE ensures compliance by providing EMC reports, powertrain matching certificates, and nationally approved documents to ensure road legality.
Real User Voices: Three Types of People Choosing Conversion
"I just commute daily; I don't need a fancy new car. The 150km range after conversion is perfectly adequate. Saving hundreds of dollars monthly on fuel is fantastic!"
"We converted 30 Wuling fleet vehicles, each costing only about $4,500. We'll recoup costs within 3 years, and now we can enter low-emission zones!"
"Couldn't bear to sell my father's old Nissan. After conversion, it drives smoother than ever—even the kids fight over driving it!"

EV conversion legality varies by country but is increasingly accepted worldwide. In the UK, France, Germany, and several other countries, properly certified conversions are fully legal. CMVTE ensures all conversions meet local regulatory requirements and provides necessary documentation for registration. Always check with local authorities for specific requirements in your area.
Performance depends on the conversion quality and components used. Well-executed conversions can offer acceleration and driving dynamics comparable to entry-level new EVs. However, new EVs typically have more sophisticated battery thermal management, more efficient motors, and integrated software systems. For daily commuting and general use, a properly converted EV provides more than adequate performance at a fraction of the cost.
Range varies based on battery capacity and vehicle efficiency. Most conversions using standard CMVTE kits achieve 100-200 km (60-125 miles) of real-world range, which is sufficient for daily commuting and urban use. Higher-range configurations are available for additional cost. While this is less than many new EVs (which often offer 300+ km), it's adequate for most daily needs at a significantly lower price point.
While technically possible to convert most vehicles, some are better suited than others. Lightweight cars with good structural condition and adequate space for batteries are ideal. CMVTE has proven compatibility with popular models like Toyota Corolla, Nissan Sylphy, Volkswagen Polo, and others. Very heavy vehicles or those with complex all-wheel-drive systems present greater challenges and higher costs.
A professional conversion typically takes 1-3 weeks depending on vehicle complexity and workshop capacity. DIY conversions with comprehensive kits can take several weekends to a few months for enthusiasts. CMVTE's modular kit design has reduced installation time by 40% compared to traditional methods, making the process more accessible than ever before.
