Smart Car Dimensions Compared: From Tiny Fortwo to Spacious #6
The Smart brand has come a long way from its ultra-compact city car roots — today’s lineup includes everything from the tiny two-seat Fortwo to the mid-size #6 sedan that’s nearly twice as long.
If you’re shopping for a Smart, understanding the dimensions is crucial. The classic Fortwo is famous for its parking-friendly size, but the new electric models have grown considerably. Let’s break down exactly how big each model is, both in numbers and in real-world context.
TL;DR
The original Smart Fortwo is tiny at just 2,695 mm (8’10”) long , while the new Smart #6 sedan stretches to 4,906 mm (16’1″) — nearly double the length . The Smart #1 sits in the middle at 4,270 mm long, 1,822 mm wide, and 1,636 mm tall, with a 2,750 mm wheelbase that’s actually longer than the entire Fortwo . The Brabus version of the #1 is slightly longer at 4,300 mm . Smart has evolved from a micro-car brand into a full EV lineup ranging from compact SUVs to mid-size sedans.

The Classic: Smart Fortwo — Still Tiny
The original Smart Fortwo remains the brand’s most recognizable model. At just 2,695 mm (8’10”) long, it’s shorter than many parking spaces. This is the car that made Smart famous for urban agility.
Key dimensions:
- Length: 2,695 mm
- Width: 1,559 mm
- Height: 1,565 mm
- Wheelbase: 1,867 mm
- Turning radius: Just 4.37 meters — tight enough to U-turn on narrow streets
The Fortwo has just 2 seats, making it purely a city commuter car. Its curb weight is around 975 kg — incredibly light . It’s also low to the ground with a ground clearance of just 132 mm .
Here’s a mind-bending fact: the Smart #1’s wheelbase of 2,750 mm is actually longer than the entire Fortwo . The #1’s wheelbase alone is 83 mm longer than the Fortwo’s total length.
Smart #1: The New Era Compact SUV
The Smart #1 marks the brand’s transformation under the Geely joint venture. It’s a 5-door, 5-seat electric SUV that’s a completely different vehicle from the Fortwo.
Dimensions
| Dimension | Metric | Imperial |
|---|---|---|
| Length | 4,270 mm | 14’0″ |
| Width | 1,822 mm | 5’12” |
| Width (with mirrors) | 2,025 mm | 6’8″ |
| Height | 1,636 mm | 5’4″ |
| Wheelbase | 2,750 mm | 9’0″ |
| Ground clearance | 182 mm | 7.2″ |
| Turning circle | 11.0 m | 36.1 ft |
The #1 is considered a small SUV, roughly the size of a Vauxhall Corsa E . It’s significantly wider and taller than the Fortwo, offering much more interior space.
The Brabus performance version is slightly longer at 4,300 mm, but shares the same width, height, and wheelbase .
Cargo Capacity
- Seats up: 323 liters (or 273 liters depending on measurement method)
- Seats folded: 986 liters
- Frunk (front trunk): 15 liters (small, mostly for charging cables)
The boot is on the small side for a crossover — a Volkswagen ID.3 offers 385 liters with seats up, compared to the #1’s 273-323 liters .
Smart #3: The Coupe-SUV
The Smart #3 is a coupe-SUV — essentially a sportier, lower-roof version of the #1. MotorTrend reports the dimensions as roughly :
- Length: ~4,400 mm (4.0 inches longer than #1)
- Width: ~1,848 mm (0.75 inches wider than #1)
- Height: ~1,557 mm (3.2 inches lower than #1)
- Wheelbase: 2,785 mm (1.3 inches longer than #1)
The #3 is about the size of a Jeep Compass, with a wheelbase almost 6 inches longer than the Compass . Despite being larger, it weighs only 22 pounds more than the #1 .
Smart #6: The Largest Smart Ever
The Smart #6 is a mid-size plug-in hybrid sedan — and it’s the biggest Smart ever made .
Dimensions
| Dimension | Metric | Imperial |
|---|---|---|
| Length | 4,906 mm | 16’1″ |
| Width | 1,922 mm | 6’4″ |
| Height | 1,508 mm | 4’11” |
| Wheelbase | 2,926 mm | 9’7″ |
The #6 is about the same size as a Toyota Camry or a Mercedes C-Class . It’s nearly double the length of the original Smart Fortwo .
The #6 represents a major departure from Smart’s original ultra-compact city car philosophy. It’s a full-sized sedan with a plug-in hybrid powertrain, designed to compete in the mainstream mid-size market .
Putting It in Perspective: Smart vs. Familiar Cars
