The BMW 2002 is one of the most rewarding classic cars to convert to electric. At roughly 1,000 kg with rear-wheel drive, a simple engine bay, and mature aftermarket support, it offers a straight path to a silent, emissions-free driving experience that preserves everything enthusiasts love about the platform.
Why the BMW 2002?
The 2002 is a lightweight (≈1,000kg) rear-wheel-drive sedan with ample engine bay space and a simple mechanical layout. The original 2.0L M10 engine and transmission are well-documented for removal, and the transmission tunnel accommodates both the original 4-speed manual and modern adapter plates. The chassis is robust enough to handle the added weight of a battery pack (approximately 150-250kg depending on capacity) without requiring structural reinforcement.
Key advantages for conversion: no complex ECU systems to decode, mechanical throttle linkage (easy to replace with a pedal position sensor), large trunk and under-seat areas for battery placement, and a strong enthusiast community with documented conversion knowledge.
Recommended CMVTE System
| Component | Specification |
| Motor | 25-50kW AC induction or PMSM |
| Controller | FOC with CANbus, pre-programmed |
| Battery | 24-50kWh LFP pack, 144V+ |
| BMS | Active balancing with cell monitoring |
| Adapter plate | For 2002 4-speed manual transmission |
| Accessories | EPS kit, vacuum pump, heater, DC-DC |
A 25kW PMSM motor with a 30kWh LFP battery is the sweet spot for the 2002: 140-160 km range, 0-100 km/h in 7-9 seconds, and retained use of the original 4-speed manual gearbox. The clutch is used only for starting from a stop — once moving, you can shift without the clutch thanks to the electric motor's instant torque response.
Battery Placement Options
The 2002 offers three battery locations that can be combined: the engine bay (fits a 10-15kWh pack in the space of the removed M10 engine and radiator), the fuel tank area under the rear seat (15-25kWh — the ideal location for weight distribution), and a shallow pack in the trunk floor (10-15kWh with minimal cargo intrusion). CMVTE designs the pack layout for each build, prioritising a target 50:50 front-rear weight distribution. A 30kWh combined pack using engine bay + fuel tank locations keeps the trunk free and maintains the 2002's balanced handling.
Conversion Process
- Remove the M10 engine, fuel tank, exhaust system, and radiator.
- Mount the CMVTE electric motor to the original 2002 transmission using the included adapter plate and coupler.
- Install the battery pack in the engine bay (10-15kWh) and in the space where the fuel tank was located (additional 15-25kWh).
- Wire the controller, BMS, charger, DC-DC converter, and accessories using the pre-labelled harness.
- Install the vacuum pump for brake assist, electric power steering (CMVTE EPS kit is a direct fit for 2002 columns), and an electric heater for cabin warmth.
- Configure the VCU, test all systems, and take the car for certification inspection.
Cost Breakdown
| Item | Cost (USD) |
| Motor + controller kit (25kW PMSM) | $4,000 – $6,000 |
| Battery pack + BMS (30kWh LFP) | $5,000 – $8,000 |
| Charger, DC-DC, accessories | $1,500 – $2,500 |
| Adapter plate, mounts, coupler | $500 – $1,000 |
| EPS kit (recommended) | $400 – $700 |
| Professional installation | $3,000 – $6,000 |
| Certification & registration | $500 – $2,000 |
| Total | $18,000 – $30,000 |
A US Parts Retailer Kit for the 2002 typically ships components from multiple brands — a Hyper9 motor from one supplier, a Curtis controller from another, a battery from a third. You pay for each separately, plus shipping, and then spend weeks matching connectors and tuning parameters. CMVTE delivers a complete, tested system with one wiring harness, one set of documentation, and one support contact.
Driving Experience
A converted 2002 with a 25kW PMSM motor retains the character that made the original famous: light weight, precise steering (especially with CMVTE EPS assist), and a direct connection to the road. The electric drivetrain eliminates engine vibration and exhaust noise, replacing them with instant torque response and a silent cabin. The 2002's original 4-speed gearshift remains — you row through the gears as before, but without the engine note changing. It is a surreal experience: a vintage sports sedan that drives like a modern EV.
Running costs are minimal. Electricity at $0.12/kWh costs roughly $0.02/km. Over 10,000 km/year, that is $200 — compared to $1,500+ for premium fuel in a stock 2002. The savings offset the conversion investment within 5-7 years of regular driving.
