The starter on a Smart Fortwo petrol model sits on the engine block near the flywheel (the bell housing) at the rear of the car; electric Smart Fortwo models do not use a traditional starter motor.
Smart cars place their engine or drive unit in the rear, behind the passenger compartment. This compact layout means the starter is tucked close to the transmission bell housing and is typically accessed from beneath the vehicle or through rear wheel arch areas. Access to the starter can vary by generation and market, and owners should consult the service manual or a qualified technician for exact location and procedures. If you’re diagnosing starting problems, remember that electric models operate without a conventional starter and rely on the drive motor and control electronics instead.
Petrol and diesel Fortwo: where the starter sits
The following details describe the traditional starter in petrol/diesel Smart Fortwo models and how to locate it, given the rear-engine layout.
- Location: The starter is bolted to the engine block near the flywheel/bell housing at the rear of the vehicle.
- Access: In many models it is reachable from underneath the car or through removed rear wheel arch shields and engine bay panels due to the compact, rear-mounted engine layout.
- Visual cues: The starter is a small cylindrical unit with wiring harness connections, usually located where the engine meets the transmission.
- Common signs of failure: slow or intermittent cranking, grinding noises, or no crank at all when turning the key or pressing the start button.
In practice, locating the starter means working in a tight rear engine bay, which may require removing trim pieces or shields. If you’re unsure, consult a repair manual for your exact model year and consider professional assistance to avoid damage to electrical connections or the battery system.
Electric Fortwo (EQ): no traditional starter
Electric Smart Fortwo models do not use a separate starter motor. The electric drive unit is engaged electronically by the vehicle’s inverter and control software, so there is no mechanical starter to locate or service.
- No separate starter: The propulsion motor is controlled electronically; there is no solenoid and no flywheel-to-starter engagement.
- Starting sequence: Pressing the start/stop control simply enables the electric motor; there is no cranking sound or mechanical engagement like a combustion engine.
- What to check if it won’t start: Check the state of charge of the high-voltage battery, the 12V auxiliary battery, relevant fuses, and the vehicle’s control electronics. If problems persist, service may be required from a qualified technician trained in high-voltage systems.
Because high-voltage systems are involved, do not attempt to service or disconnect HV components yourself unless you are trained and follow proper safety procedures. When in doubt, contact a Smart service center.
Safety and maintenance notes
Whether your Smart is petrol or electric, handling the engine bay area requires caution. Always disconnect the battery (and observe immobilization procedures) before performing any work near the starter or electrical connections. For electric cars, rely on trained technicians for any high-voltage work and refer to the owner's manual for safety guidelines and service intervals.
Summary
In summary, the starter location on a Smart Fortwo varies by powertrain: petrol and diesel models place the starter on the engine block near the rear flywheel, often accessed from underneath or via rear panels; electric models do not have a traditional starter and start via the electric drive unit controlled by the vehicle’s electronics. For accurate location and procedures, consult model-specific manuals or a qualified technician, especially given the compact, rear-engine layout of Smart vehicles.
