If you’re after a motorhome that won’t have you reversing out of every country lane or car park, the Chausson Flash 510 might just tick your boxes. This 2015 French-built compact offers four berths in under six metres, which is no mean feat when you consider how many manufacturers struggle to fit a decent layout into anything shorter than 6.5 metres.
The Flash 510 represents Chausson’s approach to maximising space without creating a behemoth that’ll have you sweating through narrow village streets. With its electric drop-down bed system and separate shower compartment, it’s clearly aimed at couples who occasionally need extra sleeping space, or perhaps small families who don’t mind getting cosy. At 641kg payload, you’ll need to pack thoughtfully, but that’s the trade-off for staying under 3.5 tonnes.
Size and Practicality of the Flash 510
At 5.99 metres long and 2.35 metres wide, the Chausson Flash 510 sits in that sweet spot where you can still fit into most standard parking spaces whilst having enough interior room to live in. The 2.92-metre height means you’ll clear most car park barriers, though you’ll still need to watch for those sneaky 2.8-metre restrictions that seem to pop up everywhere these days.
When you’re navigating British roads, that sub-six-metre length becomes genuinely useful. You’d likely find country pubs and National Trust car parks far more accommodating than they would be with a seven-metre van. The turning circle should be manageable enough for most drivers, though you’ll still want to plan your routes carefully if you’re heading into the Cotswolds or similar areas where roads were designed for horses rather than motorhomes.
Driving the Chausson Flash 510
The Ford Transit 2.2-litre diesel engine provides the motivation, paired with a six-speed manual gearbox in this 2015 model. You’d expect reasonable fuel economy from this combination, probably somewhere in the mid-twenties mpg range when you’re not pushing too hard.
The Transit chassis has a solid reputation for reliability, which matters when you’re potentially miles from the nearest Ford dealer.
Cruise control comes as standard, which you’ll appreciate on longer motorway stretches. The Bluetooth connectivity means you can keep your phone calls legal, though the infotainment system won’t be as sophisticated as what you’d find in newer models. Air conditioning is included, which is worth having during those unexpectedly warm British summers or if you’re planning continental trips.
Living Space in the Flash 510
The interior layout makes clever use of the available space, though at under six metres, you’re inevitably making compromises. The half-leather interior should wear better than full fabric, particularly if you’re planning regular use. You’ll find the living area centres around a dinette arrangement that converts into one of the sleeping areas.
Storage becomes critical in a compact motorhome like this, and you’d need to be quite disciplined about what you bring along. The payload of 641kg sounds reasonable until you start adding water, gas, food, clothes, and all the other essentials. Two people could manage comfortably for weekend trips, but longer tours would require careful planning.
Flash 510 Sleeping Arrangements
The electric drop-down bed is the Flash 510’s party trick, creating a double bed above the cab area at the touch of a button. This is genuinely useful, no wrestling with heavy manual mechanisms or complex folding procedures. When lowered, you’d have a proper double bed that doesn’t require dismantling the dining area each night.
The dinette converts into additional sleeping space, giving you the four-berth capacity. However, you’d probably find this arrangement works better for children than adults, as the converted dinette won’t offer the same comfort as a dedicated bed. For couples touring alone, you could leave the dinette as seating and just use the drop-down bed.
Kitchen Space in the Chausson
The kitchen runs along one side and includes a three-ring hob, microwave, and fridge freezer. This combination gives you reasonable cooking flexibility, though you’d need to be realistic about meal complexity in the limited space. The fridge freezer is particularly useful for longer trips where fresh food storage becomes important.
Worktop space will be at a premium, as it always is in compact motorhomes. You’d likely find yourself using the dinette table as additional prep space when cooking anything more elaborate than a simple meal. Storage for pots, pans, and provisions requires careful organisation, but the layout seems logical enough.
The Flash 510’s Shower Room
A separate shower compartment in a sub-six-metre motorhome is genuinely impressive. Many manufacturers resort to combined shower/toilet arrangements at this size, so Chausson deserves credit for maintaining separation. You’d have a proper shower experience rather than the awkward gymnastics required in wet rooms.
The 122-litre fresh water tank and 100-litre waste capacity provide reasonable autonomy for a motorhome this size. You’d probably get three to four days of normal use before needing to find services, depending on your shower habits and washing up frequency.
Power and Water Systems
The electrical system appears straightforward, though you’d want to check the leisure battery capacity and charging arrangements. With air conditioning fitted, you’d need to be mindful of power consumption when not on hookup. The 122-litre fresh water capacity is generous for the size, giving you good independence from campsites.
Gas supply handles the hob and likely the heating system, though specific details about the heating arrangement aren’t clear. You’d probably find a blown-air system that should keep the compact interior comfortable in cooler weather.
Flash 510 External Features
The side awning extends your living space when weather permits, which is particularly valuable given the compact interior. A tow bar facility means you could bring a small car along, though you’d need to watch your weight limits carefully. The bike rack provides another transport option that doesn’t eat into your payload allowance.
These external features suggest Chausson designed the Flash 510 for active users who want to explore once they’ve reached their destination. The combination of towing capability and bike storage gives you flexibility in how you tour.
Other Motorhomes Worth Considering
The Chausson Flash 03 Updated Family Layout Refinements Review offers a different layout approach from the same manufacturer, potentially with more recent updates and refinements to the basic concept.
If you’re open to different manufacturers, the Roller Team Auto Roller 600 Italian Engineering Similar Size Alternative provides Italian engineering in a similar size category, though with different layout priorities and potentially different build quality approaches.
The Benimar Mileo 282 Spanish Motorhome Building Excellence represents Spanish motorhome building and might offer different features or value propositions in the compact four-berth segment.
Final Thoughts
The Chausson Flash 510 tackles the challenge of creating a genuinely usable four-berth motorhome in under six metres, and largely succeeds. The electric drop-down bed system and separate shower are standout features that many competitors can’t match at this size.
However, you’d need to be realistic about the payload limitations and compact living space.
This motorhome would suit couples who occasionally need extra sleeping space, or small families who prioritise manoeuvrability over spacious living. The Ford Transit base provides mechanical reliability, whilst the French coachbuilding brings different design priorities than you’d find in British or German alternatives. At eight years old, you’d want a thorough inspection, but the low mileage suggests careful previous ownership.
If you can live with the space constraints and payload limitations, the Flash 510 offers a practical solution for those who want to explore without driving something the size of a small bus.
