About the Smart Fortwo 451: What Is It and Who Uses It?

The Smart Fortwo 451 is the second generation of the iconic two-seater microcar produced by Smart, a brand originally developed as a joint venture between Swatch and Mercedes-Benz. Introduced in 2007, the 451 series replaced the earlier 450 model and brought notable improvements in design, safety, and technology1. The "451" refers to the internal chassis code used by Smart, distinguishing it from the first-generation 450 and third-generation 453 models.

This compact vehicle is primarily designed for urban environments where space is limited and fuel efficiency matters. Its small footprint makes it ideal for navigating narrow streets, fitting into tight parking spots, and reducing congestion in densely populated areas. Typical users include city dwellers, commuters, students, and eco-conscious drivers looking for an affordable, low-emission vehicle for daily short-distance travel.

While often associated with novelty due to its size, the 451 offers real utility in crowded metropolitan settings. It's also popular among collectors and enthusiasts of microcars, especially special editions like the Brabus-tuned versions or limited-run color variants.

Why the Smart Fortwo 451 Is Still Relevant Today

Despite being out of production since 2014, interest in the Smart Fortwo 451 remains strong in the used car market. One reason is rising urbanization—more people live in cities where parking is scarce and traffic is heavy. The 451’s length of just 2.69 meters (about 8.8 feet) allows it to park in spaces most cars cannot fit1.

Fuel economy is another major draw. The gasoline-powered 451 typically achieves around 36–41 mpg (combined), while the diesel variant can reach up to 58 mpg under optimal conditions2. This efficiency appeals to budget-conscious drivers and those aiming to reduce their carbon footprint.

Additionally, the 451 has gained cult status over time. Its distinctive boxy design, customizable exterior panels, and unique driving experience make it stand out in a sea of conventional vehicles. As electric mobility grows, some buyers see the 451 as a stepping stone toward downsizing and rethinking personal transportation.

Verify VIN history using services like Carfax or AutoCheck (U.S.) or HPI (UK).
For bulk purchases (e.g., fleet operators), contact specialized microcar importers.
Inspect electrical systems, cooling fans, and AC operation—common failure points.

Maintenance, Safety & Legal Considerations

Regular maintenance includes oil changes every 7,500–10,000 miles, brake inspections, and coolant flushes. Pay special attention to the transmission actuator—a known weak point. Replacement intervals vary; consult service records.

Safety-wise, the 451 earned a four-star Euro NCAP rating in 2007, with strong occupant protection but marginal pedestrian safety1. It lacks modern driver aids like lane assist or automatic braking.

Legally, ensure the vehicle meets your country’s import and emissions standards. In the U.S., post-2008 models comply with federal regulations. In California, check CARB compliance. Always verify title status and registration eligibility before purchase.
