The Smart ForFour stands out in the crowded city car segment with its unique rear-engine layout, exceptional turning radius, and surprising practicality. Designed primarily for tight urban environments, this five-door hatchback combines the agility of its smaller ForTwo sibling with added seating and cargo flexibility, making it a smart choice for city dwellers needing more than a two-seater.
Design and Dimensions: Compact Yet Capable
Measuring just 3.49 meters in length and 1.66 meters wide, the ForFour slips effortlessly into the smallest parking spots. Its boxy, upright shape maximizes interior volume while maintaining a distinctive, playful aesthetic inspired by Mercedes influences, featuring bold colors and high-quality materials for a premium feel. The rear-wheel-drive setup, a hallmark of Smart’s engineering, positions the engine at the back, freeing up front space for sharper steering angles and a class-leading kerb-to-kerb turning circle of 8.65 meters—far better than most rivals.
This configuration not only enhances maneuverability but also contributes to safety, as the extended front crash structure absorbs impacts effectively. Euro NCAP awarded it four stars, excelling in whiplash protection for both front and rear occupants and outperforming competitors like the Renault Twingo in frontal crashes.
Interior Space and Versatility: More Room Than Meets the Eye
Despite its diminutive exterior, the ForFour surprises with generous interior room. Rear passengers benefit from decent legroom and headroom, suitable for adults on short trips, marking a significant improvement over earlier generations. The cabin boasts a raised driving position for better visibility, Mercedes-sourced gauges, and a touchscreen infotainment system shared with the Renault Twingo.
- Folding rear seats (50:50 split): Create a flat 975-liter cargo area, outpacing many segment rivals.
- Flip-forward rear squabs: Accommodate bulky items like a 50-inch TV.
- Fold-flat front passenger seat: Enables loading of lengthy objects up to 2.2 meters, such as flat-pack furniture.
Additional niceties include heated front seats, electronic window and mirror controls, parking sensors, and auto start-stop for efficiency. While the steering wheel lacks reach adjustment, a height-adjustable option is available for a modest fee. Cup holders and a smartphone tray enhance daily usability.
Driving Experience: Fun, Balanced, and Efficient
The ForFour shines in urban settings with its instant torque delivery and puppy-like enthusiasm. Petrol variants, like the 71bhp three-cylinder, rev willingly up to 40 mph, offering tuneful performance in town but requiring planning for highway overtakes. The suspension delivers supple damping and excellent body control, masking the short wheelbase for refined ride quality, especially on 15-inch wheels.
A neutral balance encourages smooth driving, with hints of mid-corner oversteer for the finesse-oriented driver, though stability control limits aggressive antics. It handles crosswinds and body lean adequately but prioritizes comfort over sportiness. The electric EQ ForFour, with an 80bhp rear-mounted motor and 160Nm torque, accelerates to 62mph in 12.7 seconds, feeling lively at low speeds. Its narrow body and tiny turning circle make navigating crowded streets effortless.
| Model Variant | Power | 0-62mph | Turning Circle | Key Feature |
|---|---|---|---|---|
| Petrol 0.9 Turbo | 71-90bhp | ~11-12s | 8.65m | Versatile folding seats |
| EQ ForFour Electric | 80bhp | 12.7s | 8.65m | Instant torque, low costs |
| Prime Trim | Varies | ~10s | 8.65m | Premium interior touches |
Performance and Efficiency Across Variants
Petrol models balance fun with frugality, aided by rear-axle control that rivals larger cars. The EQ version offers competitive urban range, though real-world figures may limit longer trips; post-grant pricing around £17,285 pits it against VW e-up! and similar. All variants emphasize low running costs, with electric models excelling in zero-emission zones.
Safety and Reliability: Built to Protect
Beyond Euro NCAP’s four-star rating, the ForFour’s structure provides good whiplash protection and frontal impact performance. Features like parking sensors and auto lights bolster everyday safety. As a used buy from 2015-2023, it retains Smart’s reputation for clever engineering without compromising brand values.
Pricing and Value: Competitive in Class
New EQ models start competitively after incentives, while used petrol variants are available from £3,995. Loaded with kit like big-car tech, it offers strong value over plainer city cars. Personalization options add flair without excess cost.
Pros and Cons at a Glance
- Pros: Unmatched turning circle, versatile loading, engaging drive, premium interior, efficient electric option.
- Cons: Limited highway power in base engines, fixed steering wheel standard, EV range for urban focus only, some body lean.

Ideal for urban commuters, young families, or anyone prioritizing maneuverability and fun over long-distance cruising. It builds on the ForTwo’s success with four seats and superior practicality, distinguishing itself from stablemate Twingo.
