The Smart SGE 200 – Electric is a permanent — magnet synchronous motor developed jointly by Smart and Geely, introduced in 2022 for the all — electric Smart #1 crossover. It delivers 200 kW (272 PS) and 343 Nm of torque through a single — speed reduction gearbox, enabling 0–100 km/h in 6.7 seconds. The motor architecture integrates oil — cooling and hairpin winding technology to enhance thermal efficiency and power density.

Smart
All production years (2022–present) meet zero tailpipe emissions standards under EU Regulation (EU) 2019/631 and UK.
The Smart SGE 200 – Electric is a 200 kW permanent-magnet synchronous motor engineered for compact premium EVs (2022–present). It combines hairpin winding with direct oil-cooling to deliver high torque density and thermal resilience. Designed to meet EU zero-emission vehicle mandates, it enables agile performance with minimal maintenance.

The Smart SGE 200 – Electric was used across Smart's SEA platform with transverse mounting and developed under the Geely–Mercedes-Benz joint venture. This motor received platform-specific adaptations—integrated inverter housing in the #1 Pro+ and revised gearbox ratios in the #1 Pulse—and from 2024 the facelifted #1 models adopted updated thermal management hardware, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The SGE 200 – Electric is mechanically robust with no combustion-related wear, but early software (pre-Q3 2023) caused drivability glitches. Post-update units show excellent reliability. Adherence to 20,000 km motor oil changes and avoiding excessive DC fast charging help ensure longevity.
The main issues are inverter software torque interruptions (fixed via update), motor oil leaks from rear seals, gearbox whine in early batches, and airlocks in the oil-cooling circuit after service. All are documented in Geely service bulletins EV-2023-08 through EV-2023-12.
Exclusively used in the Smart #1 (2022–present), specifically the Pulse and Pro+ trims. It is not shared with other Geely brands in this output configuration, though the SEA platform underpins Volvo EX30 and Polestar 4 with different motor variants.
No official tuning path exists. Geely locks inverter parameters via secure bootloader. Third-party remaps risk voiding warranty and damaging the inverter or battery. The motor’s thermal and electrical limits are tightly managed by factory software for safety and durability.
In the Smart #1 Pro+, real-world consumption averages 16.5 kWh/100km (city) and 19.2 kWh/100km (highway), or ~4.8 mi/kWh combined. This translates to ~250–280 km (155–174 miles) range in mixed UK driving on a 66 kWh battery.
Not applicable—electric motors have no pistons, valves, or timing systems. Mechanical failure is extremely rare; the primary risks are electronic (inverter) or thermal (cooling). No catastrophic interference scenario exists.
Geely specifies G-EMO 10W-40 electric motor oil, changed every 20,000 km. This dielectric fluid cools the stator and rotor directly. Never substitute with conventional engine or gearbox oil—doing so risks short circuits and bearing wear.
