Swift Challenger Grande 670

The Swift Challenger Grande 670 is a family-friendly caravan that stands out with its innovative design and spacious layout. With an eight-foot width, it features an L-shaped kitchen that maximises storage and surface area, making it ideal for feeding up to six people. The rear bedroom comfortably accommodates four, with a double bed and two bunks, allowing parents to enjoy their own space in the lounge without disturbing sleeping children. With stylish interiors featuring tartan-inspired fabrics and luxurious cushions, the Challenger Grande 670 combines practicality with elegance, making it perfect for family adventures.

Layout trends make interesting study. The biggest of them all in recent years, of course, has been the rise in the number of eight-foot-wide models. The extra width has brought about greater flexibility in terms of layout that has given rise to configurations that would not have been possible on a standard-width platform; shower rooms alongside double beds are an obvious example. Now, we’re seeing a rise in the number of L-shaped kitchens, with cabinets protruding in the central area of the caravan, creating more storage space and more surface, too. 

Coachman has L-shaped kitchens in its six Lasers and its three Lussos, Bailey in three of its four Alicanto models, and there is a slight L-shape to the kitchen of the Buccaneer Barracuda. Swift now has 14 L-shaped kitchens. These are in all five of its top-spec Elegance Grande models, all four of its standard-width Challengers, and, for 2025, all five of its Challenger Grande models.  That’s the single-axle 560L and 580 and. The twin-axle 635, 650L – and this one, the 670.   

This is the family Challenger Grande. If you think L-shaped kitchens are trend-setters (and you’d be right), the 670 has a bedroom layout that’s awesome in terms of innovation. The rear sector is a true family bedroom, with beds for four. That’s a double bed plus two bunks. It’s not the only caravan of this layout in the marketplace; it has the company of two Elddis models, the Crusader Tempest and the Avante 868, and the Bailey Pegasus GT75 Amalfi. All four are perfect examples of layout invention that has been made possible by eight-foot width, the biggest element in touring caravan evolution since the advent of the fixed double bed.  

The Swift take on this novel way of accommodating a family was ours for a day at Leisure Sales, in Cheshire – and the team here sited the 670 on the retailer’s spacious lawn, away from the display area. Sometimes used to host promotional events, this hardstanding-and-grass site is a perfect venue for our review, with a campsite feel.  

Every which way you look at the 670 it has space in spades. The shower room – set forward of the bedroom – is generously proportioned; definitely designed with family use in mind. 

Kitchen surface is up to the task of feeding six. And the lounge is long enough for all six to sit together. Now for the details…  

We’ll start in the bedroom, since that’s what makes the 670 stand out from the crowd. The double bed is 1.86m long and 1.22m wide; that’s about 11cm less in width than most island beds, and has an angled cut-off area that provides an ample corridor between the double bed and the bunks. So the bed isn’t over-generous in width – and that gives a clue to the flexibility of use on offer here. You could think of the double bed as the parents’ domain. But think again. Parents have the option of transforming the lounge into a giant double bed.

In this scenario, the bedroom becomes the kids  zone. And it’s perfect for a very young family. The two older children will get the bunks, and the double bed is ideal for a carrycot – with plenty of space alongside to roll out a sleeping bag for another little caravanner. So four babes and juniors can have the bedroom to themselves – and here’s the important factor: this means the parents can stay up in the lounge for as long as they like, with minimal risk of disturbing the sleeping ones. When it comes to bedtime, parents have the luxury of a lounge conversion bed that’s 2.18m long and 1.68m wide. That’s 18cm wider than a standard king-size bed. Family harmony perfection? Certainly pretty close to it.  

And storage? Two wardrobes – one in the bedroom (that’s 43cm wide and contains three shelf spaces), and one alongside the fridge; that’s 53cm wide and has three even larger shelf areas.  There’s good space under the lower bunk, under the double bed – and under the lounge sofas, plus four upper lockers in the bedroom and six in the lounge – and there’s an exterior hatch to the nearside under-seating area.  

Spec level is impressive and includes two Al-Ko Secure wheel locks, a barbecue point, a cold water exterior shower point, a Truma Waterline for connection to a tap on a pitch, an onboard 30-litre water tank, an alarm system and Al-Ko’s Automatic Trailer Control (ATC) sway-detector and braking system that corrects instability at the first signs.  

New features for 2025 include a 120W solar panel, a wireless phone charging pad set into the windowsill – and the new L-shaped kitchen that gives you a total length of 1.12m forward of the hob when the generously sized (35cm by 56cm) extension is in place. Importantly the L-shape means that the kitchen surface is 75cm deep, so there’s ample space around the 38cm-diameter sink. 

And cabinet space? The L shape gives rise to a large cabinet that contains two drawers, 46cm by 20cm, that pull out on runners. The chopping board cover for the sink (that means the sink area can become part of the surface), and the drainer, sit in a slot inside this cabinet. Alongside, two drawers with soft-close mechanism, plus a drop down door cabinet, are all 35cm wide. There’s the usual pans cabinet unde the oven, plus, opposite, lockers above and below the fridge/freezer. This is the 133litre model with dual opening facility – it’s hinged on both sides of the door.  

The double-doored cabinet alongside the microwave is 80cm wide. Its right-hand section contains mug and plate racks. Overall, kitchen storage space is definitely up to the task of caring for six. 

There’s a new design for the washroom, incorporating marble-effect surface and more lighting than in previous models. The shower cubicle is a delight, with a ceiling-mounted, hinge-down towel rail, a shelf large enough for two shampoo bottles, and a bright light running the depth of the compartment, neatly integrated into the junction between the wall and the ceiling. 

So, lots of practicality and lots of style points to notice. The subtle tartan-inspired fabric on the panels that flank the lounge’s side windows inject a hint of traditional style. The cushions create a luxury look, with shimmering pale gold fabrics for the largest of the square cushions and for the bolsters. The smaller pair of square cushions, in dark green velvet, adds a touch of classic richness. 

Accommodating up to six in a caravan is always a challenge for  caravan designers, and this clever bedroom layout solution has definite appeal to families with very young children. 

Its versatility is its key to family caravanning harmony; who sleeps where depends on ages and preferences. 

However you use the four-person bedroom, its great advantage is that it’s a long way from the lounge in terms of light and noise exclusion. 

At £38,745. the 670 sits in the fiercely competitive middle price ground, and we think it acquits itself superbly for its quite specific market.
