Atom Core 600 B vs Swift Merlin 122 and Auto-Trail Expedition 66: is a VW Crafter rear lounge worth the money?

The Atom Core 600 B is a two-berth campervan with a sofa at the back. That is the simple version. The fuller version is that it is a Volkswagen Crafter conversion priced to sit among Fiat Ducato campervans that are cheaper, better equipped, or both. So the whole decision comes down to one question: do you value the VW base more than the extra kit or the money saved? This piece lays out the real numbers, as listed on 5 October 2026, so you can make that call yourself.

Atom in two lines

Atom is a new British campervan brand from the Trigano group, selling VW Crafter conversions directly to customers rather than through dealers. There are two trim levels, Core and Element, each offered in a rear lounge (600 B) or a twin-single-beds-over-a-garage (600 G) layout, and nothing else yet.

What the Core 600 B is and what it costs

On Atom's own site and configurator the Core 600 B is £62,600 on the road, made up of £62,155 for the van plus £445 in charges. At the time of writing Atom is also showing a winter sale price of £60,655, so the gap between the Atom and its rivals moves by nearly £2,000 depending on when you order. Prices are correct as listed on 5 October 2026 and will change, so treat every figure here as a snapshot.

The basics, from Atom:

• Base vehicle: Volkswagen Crafter panel van, 140 PS diesel, six-speed manual gearbox
• Length 5.986 m, width 2.04 m, so it keeps the van's own slim steel body
• Maximum authorised mass 3,500 kg, so it drives on a standard car licence
• Two berths, two travel seats
• Mass in running order listed at 2,720 kg, which leaves about 780 kg of payload on paper

That payload figure is worth a pause. Around 780 kg is generous for a two-berth of this size, and it means a couple can carry water, a full gas locker, bikes and a week of food without nervously eyeing a weighbridge. We would still weigh it loaded before a long trip, because the running-order figure is a manufacturer number and real vans vary, but as a starting point it is reassuring.

Standard kit

Atom's "accessible" pitch does not mean stripped out. The Core 600 B comes with:

• Truma Combi Neo 4E heating and hot water (gas and mains electric)
• 70-litre compressor fridge
• Two-burner hob with an oven and grill
• Washroom with a shower and toilet
• 200 W of roof solar
• A tracker fitted from the factory
• 10-inch DAB+ infotainment screen
• 95Ah AGM leisure battery, according to Practical Motorhome

The oven and grill matter more than they sound. Not every panel van conversion at this price has an oven, and it is the difference between a hot meal on a wet October evening and another pan of pasta. The 70-litre compressor fridge is a sensible size for two, and compressor fridges cope far better with warm weather and uneven pitches than the older three-way type.

Options you will probably look at

Atom's configurator keeps the options list short, which is part of the direct-sales idea. The ones most buyers will consider:

• 340Ah lithium leisure battery: £899
• Wind-out awning: £1,095
• Reversing camera: £336
• 177 PS engine upgrade: £2,652
• VW automatic gearbox: £2,628

The lithium upgrade at £899 is the stand-out. Swapping a single 95Ah AGM for 340Ah of lithium is a big jump in usable off-grid capacity, and at that price it is hard to argue against if you plan to spend nights away from hook-up. Add the awning and camera and the Core 600 B lands at £64,930 on the road, a useful figure to keep in mind when we get to the Swift.

The rear lounge, and the bed question nobody has answered

The 600 B layout puts two facing benches at the back of the van. In a 2.04 m wide van that gives you a proper sit-and-look-out-of-the-doors space in the evening, which is the whole reason people choose a rear lounge over a fixed bed.

Here is the honest gap in the picture. Practical Motorhome reports that both Atom layouts sleep in single beds. Atom itself has not published bed dimensions for either model. In a rear lounge van, whether the two benches can be bridged into a double, and how wide and long that double is, decides whether a couple is happy in it. The Auto-Trail, Swift and Elddis rivals below all state that their rear lounges make a double. Atom has not said either way in print.

Before you order a Core 600 B, ask Atom directly whether the benches convert to a double, and get the length and width of the singles in writing. It is the single biggest unknown on this van.

Core 600 B against the rest of the Atom range

Atom's range is small enough to compare in a paragraph each.

Core 600 G: £660 less

The 600 G drops the rear lounge for two single beds over a rear garage, and costs £660 less than the 600 B. Same base, same kitchen, same washroom, same kit. If you carry bikes, surfboards or a lot of outdoor gear, the garage will probably matter more than the sofa. If you spend your evenings in the van, the 600 B's lounge is the better living space. With so little between them on price, layout, not money, should decide this one.

Element 600 B: £6,325 more

The Element is the same rear lounge van with a higher specification. For £6,325 extra you get the 340Ah lithium battery, a 3,000 W inverter, a roof rack, the awning, on-board Wi-Fi, a reversing camera, LED exterior lights and alloy wheels. Adding every matching option to a Core (lithium, awning, camera, Wi-Fi, LED headlights, alloys and the rest) costs around £7,000, and Atom does not offer the inverter or the roof rack on a Core at all.

So the arithmetic is simple. If you want most of the Element's kit, it is better value than a Core with options, and it includes an inverter and roof rack you could not otherwise buy. If you only want lithium and an awning, a Core with those two options costs £1,994 more rather than £6,325. There is no cheap route to a Core with an inverter, so if running a kettle or laptop charger off the battery is part of your plan, that pushes you to the Element.

The Fiat Ducato rivals

This is where the Atom's price has to earn its keep. Every rival here is a 2.2-litre 140 bhp Fiat Ducato panel van conversion, around 6 m long, two-berth, with a rear lounge that converts to a bed. The figures below are each maker's own listed prices and specifications on 5 October 2026. Check whether a given price includes on-the-road charges, because makers do not all present it the same way.

Auto-Trail Expedition 66: from £56,214

The Expedition 66 is also a Trigano product, which makes it the Atom's in-house rival. Auto-Trail lists it from £56,214, a 5.99 m Ducato with a rear lounge that makes a double, 200 W of solar and a 70Ah leisure battery. Against the Atom's £62,600 that is £6,386 less, or £4,441 less than Atom's winter sale price.

Where the Atom pulls ahead is the battery (95Ah against 70Ah, and a cheap lithium upgrade) and the VW base. Where the Auto-Trail pulls ahead is the bed, which is a confirmed double, and the dealer network behind it. The £6,386 difference would pay for the Atom's lithium, awning, camera and automatic gearbox with about £1,400 to spare, so you need to want the Crafter specifically.

Swift Merlin 122: £64,190

Swift's all-new 2027 Merlin range includes the 122, its 6 m rear lounge version. Swift lists it at £64,190. According to Swift, it has a U-shaped rear lounge that makes either a double or two singles and a 100Ah lithium leisure battery, and a 50-litre compressor fridge: Practical Motorhome reports that the 112 and 122 get the 50-litre unit, while the rest of the Merlin range has 80 litres. Dealers list the same 2.2-litre 140 bhp engine with a six-speed manual as standard, with an eight-speed automatic available.

This is the closest fight. The Swift is £1,590 more than the Atom's list price and includes lithium as standard, where the Atom needs the £899 option. Add that to the Atom and the gap closes to under £700. At that point the Swift gives you a U-shaped lounge and a confirmed double-or-singles bed. The Atom answers with a bigger fridge (70 litres against 50), more lithium once optioned (340Ah against 100Ah) and the VW base. Neither is obviously wrong: the Swift settles the bed question, and the Atom is the choice if battery capacity and the Crafter matter most to you.

Elddis Autoquest GTV 260: £66,827

Elddis lists the Autoquest GTV 260 at £66,827, and the headline is that an automatic gearbox is standard. Its rear benches make one large double, it carries a 95Ah AGM battery like the Atom, and it has no solar panel as standard. Compare like with like: a Core 600 B with the £2,628 VW automatic comes to £65,228, still around £1,600 less than the Elddis, and it includes 200 W of solar the Elddis does not. The Elddis wins on a confirmed large double bed and the automatic being built into the price with no decision to make.

Hillside Hopton: from £75,695

If you want to see what a VW Crafter rear lounge normally costs, Hillside lists its Hopton from £75,695. That is £13,095 more than the Atom's list price. Hillside is a smaller converter with a different approach, so it is not a straight swap, but it shows that Atom's pricing is low for a Crafter conversion rather than high for a campervan. The Atom is not expensive against other VW vans, and against these Fiats it sits in the middle on price.

The real trade: a VW base against a Fiat base

Strip the comparison back and it is this. For roughly the same money as a Ducato rival, Atom gives you a Crafter. For less money, the Expedition 66 gives you a Ducato with a confirmed double. For a little more, the Merlin 122 gives you a Ducato with lithium and a confirmed bed.

What the VW base actually buys you:

• A cab that many drivers find quieter and more car-like, with VW switchgear and a VW dealer network for the base vehicle
• A narrower body at 2.04 m, which is easier in lanes and car parks than a wider coachbuilt, though the Ducato panel vans are a similar width
• Generous payload on paper, around 780 kg
• A badge that has historically held its value well in the campervan market, though nobody can promise what a brand-new conversion brand will do on resale

What the Fiat rivals buy you:

• A lower entry price (Auto-Trail) or more standard kit (Swift, Elddis)
• A bed layout the maker has actually published
• A long record of Ducato-based conversions, which means parts, accessories and specialist knowledge are everywhere
• A dealer to walk into, where Atom sells direct

Direct sales cut both ways. You get a clear price and a short options list with no haggling. You also get fewer places to see one, sit on the benches and test the bed before you commit, which, given the unanswered bed question, is not a small thing.

What Atom has not told us

Three things a careful buyer should pin down before ordering, because they are not on Atom's site at the time of writing:

1. Bed sizes. Whether the benches make a double, and the dimensions of the singles.
2. Tank sizes. Fresh and waste water capacities are not published. For off-grid trips this matters as much as battery size.
3. Overall height. Atom's Core pages list 2,170 mm, which looks too low to be the outside height of a Crafter with standing room. If you have a car park barrier, a garage or a ferry booking to think about, ask.

None of these are red flags. New brands often launch with thin specification sheets and fill them in later. They are simply questions to ask in writing, so the answer is on paper when the van arrives.

Who the Core 600 B suits

Buy the Core 600 B if you are a couple or a solo traveller, you specifically want a VW Crafter, you like a rear lounge for evenings, and you are comfortable with an AGM battery or happy to pay £899 for lithium. At £62,600, or £60,655 in the sale, it is a cheaper way into a Crafter rear lounge than most of the market offers, with a proper kitchen, solar and heating all included.

Look at the Auto-Trail Expedition 66 instead if the Crafter badge does not matter to you and £6,000 does. Look at the Swift Merlin 122 if you want lithium and a confirmed flexible bed from the factory, and you are happy with a Ducato base and a smaller fridge. Look at the Elddis GTV 260 if you want an automatic and a big double without adding options.

And if you need four seats or four berths, none of these will do. Atom has no four-seat van at all yet, though Practical Motorhome reports the brand is looking at four-berth layouts. Until then the Core 600 B is a two-person van, priced as a VW among Fiats, with one bed question you should get answered before you sign.
