If you are looking for the most compact, maneuverable and stylish car for the city, then SMART - one of the brightest candidates. These tiny cars, which appeared in the late 90s, immediately became a symbol of urban mobility. But what's really behind their cute design? Is SMART a full-fledged car or more of a “toy” for short trips?
In this article we will look at brand history, his connection with Mercedes-Benz, technical features (including engines, transmissions and suspension), and also answer the main question: is it worth buying SMART today - new or used. We will pay special attention to the typical problems that owners encounter and provide a checklist for inspection before purchasing.
History of the SMART brand: from a joint project to a part of Mercedes-Benz
Brand SMART appeared in 1994 as a joint project of two giants: the German Mercedes-Benz and a Swiss company Swatch (famous for its watches). The idea was simple: to create an ultra-compact, environmentally friendly and stylish car for urban environments. Title SMART stood for Swatch Mercedes ART — a reflection of collaboration and a focus on design.
The first model is SMART Fortwo (C450) - published in 1998. Its key features:
- 📏 Total length 2.5 meters (less than many B class hatchbacks).
- 🔋 Engine volume
0.6–0.7 lturbocharged (power up to75 hp). - 🔄 Gearbox Softouch - semi-automatic with one clutch (later replaced with Twinamic with two clutches).
- 🛡️ Body made of plastic panels on a steel frame (unique design that allows panels to be replaced if damaged without welding).
In 2006 Mercedes-Benz bought out the share Swatch, and SMART became a completely subsidiary brand of the German concern. This affected build quality and parts availability, but also drove up prices. The latest "classic" model Fortwo (C453) was produced until 2026, after which the brand completely switched to electric vehicles (SMART #1 and #3).
SMART technical features: engines, transmission and suspension
Main advantage SMART - its dimensions, but they also impose restrictions on the technical “stuffing”. Let's look at the key components that make these machines unique (and sometimes problematic).
Engines: small displacement, large turbocharging
All petrol SMART equipped with three-cylinder engines of the series M133 (development Mercedes-AMG!):
- 🔥 0.7 l (698 cm³) - basic version (
61–75 hp). - 💨 0.9 l (898 cm³, turbo) - for models Brabus (
102–109 hp). - ⚡ Electric motor - in new SMART #1 (
272 hpin the top version).
Feature: all motors have turbocharging, which compensates for the small volume, but requires high-quality oil and timely maintenance. Engine life with proper operation - 200,000+ km, but the turbine and valve group often fail earlier.
Transmission: semi-automatic with tricks
Before 2012 SMART came with a box Softouch — semi-automatic with one clutch. Her main problems:
- ⚠️ Jerks when switching (especially at low speeds).
- 🔧 Rapid wear of the clutch (resource
80,000–100,000 km). - 💰 Expensive repairs (clutch replacement costs
30 000–50 000 ₽).
Since 2012 there has been Twinamic — preselective robot with two clutches (analogue DSG from Volkswagen). It is more reliable, but also requires careful handling: you cannot stand on a slope for a long time with the brake pedal pressed (risk of clutch overheating).
Suspension: stiffness as a feature
Due to the short wheelbase (1.87 m) and compact size suspension SMART has always been tough. This is a plus for handling, but a minus for comfort:
- 🚗 Front suspension - McPherson with wishbones.
- 🔩 Rear — De Dion (semi-independent, rarely breaks, but expensive to repair).
- ⚠️ Wheel bearings and shock absorbers wear out faster than those of conventional cars (resource
60,000–80,000 km).
If you plan to buy a used SMART, be sure to check the condition of the suspension on a lift. A knock in the front often indicates wear on the arms or ball joints, while a “pulling” to the side often indicates problems with wheel alignment.
Pros and cons of SMART: is it worth buying?
Like any unusual car, SMART has clear advantages and serious disadvantages. Let's look at them in detail so you can make an informed decision.
Benefits
- 🅿️ Parking anywhere: thanks to the size
2.5×1.5 mSMART fits into the tightest spaces (even perpendicular to the curb). - 💰 Low fuel consumption:
4–6 l/100 kmin the city (petrol versions). - 🔧 Easy body repair: Plastic panels are easy to replace without painting.
- 🚗 Maneuverability: turning radius
6.95 m(better than many supercars). - 🔋 Electric versions (SMART #1) have a power reserve of up to
440 km(WLTP).
Disadvantages
- 🚫 Limited practicality: trunk
220–350 l, the back seat is only suitable for children. - 💸 Expensive service: spare parts from Mercedes-Benz, high standard hours in services.
- 🛣️ Inability to cope with bad roads: low ground clearance (
110 mm) and rigid suspension. - ⚡ Electrical problems: frequent failures of sensors and control unit (especially in models before 2010).
⚠️ Attention: If you plan to travel outside the city or transport cargo, SMART - not the best choice. These cars were created exclusively for urban use.

How to choose a used SMART: checklist for the buyer
Purchase SMART used cars are a risky endeavor if you don't know what to look for. These cars were often bought as a “second car”, so they were treated carelessly. Here key points, which need to be checked:
Engine: no knocking, oil pressure is normal (check the dipstick)
Transmission: smooth shifts, no jerks when starting off
Suspension: no knocking, even tire wear
Electrics: all sensors work, no errors on the dashboard
Body: integrity of plastic panels, no cracks in the windshield (a common problem)
Documents: service book with maintenance notes (especially oil and turbine changes) -->
Pay special attention to:
- Turbine: appears when worn
blue smoke from the exhaust pipeand loss of power. Replacement costs80 000–120 000 ₽. - Clutch: if the car jerks when starting off and the pedal vibrates, get ready for repairs (
30 000–50 000 ₽). - Electronics: check the operation of all sensors (especially
ABSandESP), since the control unit often “glitches”.
⚠️ Attention: Many SMART operated in taxi or car sharing mode. Check the history by VIN through services like Autocode or CarVertical. If the car was rented in the past, it is better not to buy it.
What to do if SMART does not start?
If the starter turns, but the engine does not start, check:
1. Fuel pump (often fails, especially in cold weather).
2. Crankshaft position sensor (typical problem for M133).
3. Fuses (the fuse box is located under the hood on the left).
If the problem is in the electronics, you may need to reflash the control unit (cost from 15,000 ₽).
SMART vs alternatives: what is better for the city?
If compactness appeals to you SMART, but have doubts about reliability, consider alternatives. We compared key parameters with our closest competitors:
| Model | SMART Fortwo (petrol) | Toyota IQ | Fiat 500 | Mini Cooper (3-door) |
|---|---|---|---|---|
| Length, m | 2,5 | 3,0 | 3,55 | 3,82 |
| Fuel consumption, l/100 km | 4–6 | 5–6 | 5–7 | 6–8 |
| Resale price (2015–2018), ₽ | 600 000–900 000 | 800 000–1 200 000 | 700 000–1 100 000 | 1 200 000–1 800 000 |
| Reliability | Medium (problems with turbine and gearbox) | High | Above average | Average (expensive repairs) |
| Practicality | Low | Average | High | Average |
Conclusion: SMART wins in compactness and fuel consumption, but loses in reliability and practicality. If you need as small as possible car and you are ready to put up with frequent service visits, SMART - an excellent choice. For those who value reliability, it is better to consider Toyota IQ or Fiat 500.
SMART Fortwo is the only production car that can be parked perpendicular to a curb (less than 2.6 m in length). This makes it ideal for cities with a shortage of parking spaces.
Electric SMART: what has changed in the new models?
From 2022 the brand SMART switched completely to electric vehicles. New models - SMART #1 and SMART #3 — are produced in China in partnership with Geely and are sold as premium city cars. Here are their key features:
- 🔋 Battery: capacity
66 kWh, power reserve up to440 km(WLTP). - ⚡ Charging: supports
150 kW(10–80% in 30 minutes). - 💨 Dynamics: acceleration to
100 km/hfor3.9 s(in version Brabus). - 📱 Technologies: big screen
12,8", system MBUX from Mercedes, wireless Apple CarPlay.
Prices for new electric SMART start from 3 500 000 ₽, which is comparable to the cost Tesla Model 3 or BMW i4. The main question: is this price justified for a compact car? Pros:
- ✅ Low cost of ownership (no gas costs, minimal maintenance).
- ✅ Modern electronics and high level of security.
- ✅ Environmentally friendly (zero emissions).
Cons:
- ❌ Limited network of services (so far only in large cities).
- ❌ High price of spare parts (for example, replacing a battery will cost
1 000 000+ ₽). - ❌ Unusual handling (due to rear engine location).
Tuning and improvements SMART: what can be improved?
Owners SMART often strive to make their cars unique. Here are the most popular tuning areas:
1. External tuning
- 🎨 Vintage stickers (style Brabus or Crossblade).
- 🔥 LED headlights (replacing standard halogen lights).
- 🖌️ Painting panels (plastic can be easily repainted in a different color).
2. Technical tuning
- 🏁 Chip tuning: ECU firmware to increase power up to
120–150 hp(but reduces the turbine life!). - 🔧 Exhaust system replacement to forward flow (improves the sound, but may cause errors in the oxygen sensor).
- 🛞 Installing low profile tires (for example,
175/50 R15instead of standard155/60 R15).
⚠️ Attention: Any changes to the engine or transmission may result in denial of warranty (if it is still valid) and accelerated wear. For example, chip tuning without upgrading the turbine and intercooler often ends in its failure through 20,000–30,000 km.
If you want to improve the appearance of the SMART, start by replacing the hubcaps with alloy wheels (for example, from Brabus) and installing LED DRLs. It is inexpensive (from 20,000 ₽) and does not affect reliability.
FAQ: answers to frequently asked questions about SMART
Is it possible to drive the SMART on the highway?
Technically yes, but it's uncomfortable. Maximum speed SMART Fortwo — 135–150 km/h, but already at 110 km/h The engine is running at the limit, and the noise in the cabin becomes very high. For long trips it is better to choose another car.
How much does SMART insurance cost?
Cost of MTPL for SMART Fortwo (2015–2020) in Moscow - approx. 5 000–7 000 ₽ per year (depending on experience and driving history). Casco will cost 40 000–60 000 ₽ (due to the high cost of spare parts).
What kind of oil should I put in SMART?
For engines M133 synthetic oil recommended 5W-40 or 0W-40 with permission MB 229.5. Best options:
- Mobil 1 ESP Formula 5W-30
