Smart ForTwo 453-FL

Weaknesses, engine ratings and buying advice

3.0 / 5.0 · Based on 1 engine variants · How we rate

The smart ForTwo 453 in facelift form (EQ fortwo, from around 2020) marks the end of the combustion era: in this phase smart offered the ForTwo only as a pure electric car. Powered by a 60 kW electric motor with a 17.6 kWh battery, it delivers a realistic range of around 100–130 km – deliberately designed as a city car, not for long distances. As standard it charges only single-phase at 4.6 kW; the optional 22 kW on-board charger (fast AC charging) is an important feature that markedly raises resale value and everyday usability – look specifically for it when buying. DC fast charging is absent entirely. Typical issues are occasional charging aborts and communication problems with certain wallboxes and public chargers, bugs in the smart Control app (pre-conditioning, charge-level display) and the range sensitivity in cold weather and on short trips that is normal for small batteries. The drivetrain itself is regarded as uncomplicated and low-maintenance. As a second car or a pure city and commuter vehicle in an urban setting, the EQ fortwo is ideal: nimble, quiet, with the smallest turning circle in its class. The batteries of this series are so far regarded as durable and little prone to degradation, but before buying you should have the state of health (SoH) read out – on short-trip city cars real battery stress is often low, which spares the cells. Also check the 12-volt system and the software version, since outdated levels cause some of the charging problems. Market status 2026: attractively priced used (roughly 8,000–14,000 euros depending on year, equipment and battery condition); prefer models with the 22 kW charger and good battery health. As the last classic ForTwo, the model also has a certain collector's appeal as the end point of the series. Unsuitable for long journeys, but unbeatably practical in city traffic, cheap to run and with minimal maintenance needs.

Generations


Engine Overview

The Smart ForTwo 453-FL is available with 2 engine variants — from 75 to 82 hp.

EQ ForTwo · Electric· 82 PS
2020 2024

The electric drive is mechanically simple, low-maintenance and delivers the typical instant EV torque from a standstill in city traffic, ideal for the compact usage profile. Different battery sizes were used across the generations, so range varies considerably. The central purchase point is the condition of the high-voltage battery, whose capacity fades with age and charge cycles; a state-of-health readout is mandatory. The early models charge comparatively slowly. A frequently underestimated weak point is the 12-volt auxiliary battery, whose failure can trigger charging problems and a refusal to start.

No known weaknesses documented.

Vehicle Weaknesses

WeaknessCost
DC-DC Converter Defective — Charging Abort

A faulty DC-DC converter prevents the 12V battery from charging; without sufficient 12V voltage, the HV contactors cannot close. Vehicle no longer moves under its own power.

Symptoms: Fault message 'charging not possible – visit workshop', vehicle stationary, 12V voltage measurable below 13 V
from 70,000 km
High
!12V Battery Drains Quickly

The 12V lead-acid battery is not designed for the charge/discharge conditions of a BEV and sulphates. After 3–4 years a complete failure that renders the vehicle undriveable is typical.

Symptoms: App shows 12V warning, vehicle cannot be started, charging aborts with red battery symbol
from 40,000 km
Low
!Sporadic Charging Aborts at Wallboxes

Charging aborts without warning, especially with managed charging current or mains disturbances. Statistically occurs approximately every 30,000 km and usually resolves itself after a 15-minute wait.

Symptoms: Charge cable LED flashes red, error message 'charging not possible', clears after unplugging/replugging and a 15-minute pause
from 30,000 km
Low
Smart Control App — Connection Errors and Pre-Conditioning

The official app regularly loses the vehicle connection. The immediate boost for pre-conditioning functions reliably in only about 50% of cases after overnight parking.

Symptoms: App shows vehicle as offline, pre-conditioning does not start, daily re-login required
Low

Test Reports

AUTO BILD TÜV-Report 2025

Average

The facelifted ForTwo 453 shows the typical weaknesses of the model line at the MOT: dipped headlight defect rates climb above average from the second MOT onwards. Driveshafts remain fault-free; steering and track rods are rarely flagged.
