Smart Fortwo 451: The Ultimate Urban Commuter

In the bustling landscape of urban mobility, few vehicles have carved out a niche as distinctive and enduring as the Smart Fortwo. Among its various iterations, the Fortwo Series 451 stands out as a particularly refined and widely celebrated model, representing a significant evolution from its predecessor. Launched globally around 2007 and continuing production until 2014 (with some markets extending into 2015), the 451 quickly became synonymous with intelligent city driving, offering a compelling blend of compact dimensions, surprising interior comfort, and a unique personality.

Designed specifically for the challenges of congested city streets, the Smart Fortwo 451 embodies a philosophy of efficiency and practicality without sacrificing style. Its immediate appeal lies in its remarkably small footprint, which allows for unparalleled manoeuvrability and ease of parking in even the tightest spots. Yet, beneath this diminutive exterior lies a clever engineering marvel that provides a remarkably capable and comfortable experience for two occupants. This article delves into the specifics of the Smart Fortwo 451, exploring its design, performance, features, and overall suitability for modern urban living.

What Defines the Smart Fortwo 451 Series?

The Smart Fortwo 451 represents the second generation of the iconic two-seater city car, succeeding the original 450 series. While retaining the fundamental concept of a highly compact vehicle, the 451 introduced a host of improvements and refinements that enhanced its appeal. It was slightly larger than the 450, growing by approximately 8 inches (20 cm) in length, which contributed to improved crash safety and a marginally more spacious boot. This growth, however, did not detract from its core mission: to be the ultimate urban companion.

Key to the 451's identity is its distinctive two-tone design, a hallmark that has become instantly recognisable. This design isn't merely aesthetic; it highlights the vehicle's innovative construction. The car is built around a robust steel frame known as the Tridion safety cell, which is painted in a contrasting colour to the interchangeable plastic body panels. This not only gives the Smart Fortwo its signature look but also provides exceptional protection for its occupants in the event of a collision, a crucial factor for such a compact vehicle.

Under the bonnet, the 451 series saw an upgrade in engine offerings, primarily focusing on efficiency and compliance with evolving emissions standards. Both petrol and diesel engine options were available, often paired with an automated manual transmission, a characteristic feature that contributes to the car's unique driving experience.

Design and Aesthetics: A Bold Urban Statement

The Smart Fortwo 451’s design is a masterclass in making a small car stand out. Its short overhangs, tall profile, and wide stance (for its length) give it a purposeful and stable appearance. The aforementioned two-tone scheme, with the Tridion cell typically in silver or black and the body panels in a vibrant array of colours, allows for a degree of personalisation and adds to its playful yet sophisticated character. From an aesthetic perspective, the 451 looked more mature and rounded than its predecessor, with larger headlights and a more integrated bumper design.

Despite its diminutive size, the 451’s design maximises interior volume. The wheels are pushed out to the very corners of the vehicle, reducing wasted space and contributing to its impressive stability and handling for a car of its dimensions. The large glass areas, particularly in the coupé and even more so in the cabriolet variants, contribute to excellent all-round visibility, which is invaluable when navigating tight city streets or parking. Every curve and panel serves a purpose, making the 451 a highly functional piece of automotive design that perfectly encapsulates its urban mission.

Interior Ingenuity: Spaciousness in Miniature

Stepping inside the Smart Fortwo 451, many are surprised by the sense of space. While it is undeniably a two-seater, the interior is remarkably roomy for its class, offering ample head and legroom for two average-sized adults. This is achieved through clever packaging, including a high seating position and the absence of a rear bench, which allows the front occupants to sit further back within the wheelbase.

The dashboard design is functional and intuitive, with a clear instrument cluster and centrally mounted auxiliary gauges for a quirky touch. Material quality, while not luxurious, is robust and designed to withstand the rigours of daily urban use. Storage solutions are thoughtfully integrated, with door pockets, a glovebox, and various cubbies providing enough space for daily essentials. Depending on the trim level, features such as electric windows, air conditioning, and even basic infotainment systems were available, enhancing comfort and convenience.

The boot, while small, is surprisingly practical for grocery runs or a couple of overnight bags. Its accessible nature, with a split tailgate (the lower half dropping down to form a small shelf), makes loading and unloading straightforward.

Performance and Urban Agility

The Smart Fortwo 451 was never designed for outright speed, but rather for efficient and agile performance in an urban environment. Engine options typically included a range of three-cylinder petrol engines, both naturally aspirated and turbocharged, offering various power outputs. There was also a highly efficient diesel option, particularly popular in European markets, known for its excellent fuel economy.

The most distinctive aspect of the 451's driving experience is its automated manual transmission. This gearbox, while offering the convenience of automatic shifting, operates differently from a conventional torque-converter automatic or a modern dual-clutch system. It has a noticeable pause during gear changes, which can take some getting used to. However, drivers quickly learn to anticipate these shifts, often by lifting off the accelerator slightly, to ensure a smoother transition. Once mastered, the transmission proves perfectly adequate for city driving, and its design contributes to the car's fuel efficiency.

Where the 451 truly shines is its urban agility. Its incredibly tight turning circle allows it to perform U-turns in spaces larger cars could only dream of, and parallel parking becomes an effortless task. The responsive steering (optionally power-assisted) and compact dimensions make darting through traffic and squeezing into tight gaps a breeze. On motorways, the 451 can hold its own, especially the turbocharged variants, though crosswinds can be felt due to its lightweight and tall profile. However, it’s in the city that the Fortwo 451 truly feels at home, offering a nimble and engaging driving experience.

Safety: Small Car, Big Protection

One of the most common questions about any small car, especially one as compact as the Fortwo, concerns its safety. Smart engineers meticulously designed the Fortwo 451 with safety as a paramount concern. The core of its safety concept is the Tridion safety cell, a high-strength steel cage that forms the passenger compartment. This cell is designed to absorb impact energy and distribute forces around the occupants, much like a crash helmet protects a motorcyclist's head.

In addition to the Tridion cell, the 451 was equipped with a comprehensive suite of safety features, including multiple airbags (front, and optional side airbags), Anti-lock Braking System (ABS), and Electronic Stability Program (ESP). These electronic aids work together to help the driver maintain control in challenging conditions. Independent crash tests, such as those conducted by Euro NCAP, demonstrated that the Smart Fortwo 451 offered a respectable level of occupant protection for its size, often performing surprisingly well against larger vehicles in specific collision scenarios.

Heating and Climate Control: Comfort in All Seasons

A frequently asked question regarding compact cars like the Smart Fortwo 451 is whether they come equipped with essential comfort features. To directly address the query: Yes, the Smart Fortwo 451 absolutely comes with a heating system as standard. Like any modern car, it features a conventional heater that uses engine coolant to warm the cabin, ensuring occupants remain comfortable even on the coldest British winter mornings. The controls for the heating system are typically straightforward, allowing for adjustment of temperature and fan speed.

Furthermore, an air conditioning system was available as an optional extra on most 451 models, and often standard on higher trim levels. This system provides cooling for the cabin during warmer weather and also assists with dehumidifying the air, which can be beneficial for demisting windows. Some premium versions even offered automatic climate control, allowing drivers to set a desired temperature and have the system maintain it automatically. So, whether you're facing a frosty commute or a warm summer's day, the 451 is equipped to keep you comfortable.

Models and Variants

The Smart Fortwo 451 was available in two primary body styles: the Coupé and the Cabriolet. The Coupé featured a solid roof, often with a panoramic glass roof option for an airy feel. The Cabriolet, on the other hand, offered the joy of open-top motoring with an electric fabric roof that could be opened partially like a large sunroof or fully retracted, along with removable roof bars for a true convertible experience.

Over its production run, Smart also released various trim levels and special editions, offering different interior finishes, wheel designs, and equipment packages. The most notable performance variant was the Brabus edition, which featured a more powerful turbocharged engine, sportier suspension, upgraded brakes, and unique styling elements, transforming the Fortwo into a genuine pocket rocket. Additionally, the 451 series also saw the introduction of early Electric Drive (ED) models, laying the groundwork for Smart's future focus on electric propulsion, though these were initially produced in smaller numbers.

Owning a Smart Fortwo 451: Practical Considerations

For potential owners in the UK, the Smart Fortwo 451 presents a compelling package. Its excellent fuel economy, particularly with the diesel variants or smaller petrol engines, translates to lower running costs. Road tax is often minimal due to its low emissions, and insurance groups are generally favourable, making it an economical car to own.

Maintenance is relatively straightforward, though access to the engine (located at the rear) can be a bit more involved than a traditional front-engined car. Common service items are readily available, and many independent garages are familiar with these vehicles. Like any used car, prospective buyers should look for a well-maintained example with a full service history. While generally reliable, some common areas to check include the condition of the automated manual transmission (ensuring smooth shifts) and routine checks for oil leaks or electrical issues, which are not uncommon on older vehicles of any make.
