Club Campers Frontier vs BMW 428i

What's the difference?

All in all, the Frontier is the best forward-fold camper on the market, although it is also the most expensive. If you were making a buying decision purely based on features, you’d probably look elsewhere, but if you are prepared to pay a little more because this camper-trailer is Australian made, you get a very functional camper that’s easy to set up, reliable, strong and light. 

The 4 Series line offers three distinct points of difference from the more traditional 3 Series, each with their own attraction. The sharpening of the sticker prices and the additional spec helps their cause as well, with the 430i Coupe probably our pick of the range. The 440i is the firecracker of the group, while the 420d is also worth a look, thanks to its value and prodigious torque output.

The real appeal of a forward-fold camper-trailer is the internal configuration. Because the bed folds out over the front of the camper, the trailer body is configured with a wrap-around lounge and dinette area, that also converts into a bed. It brings a certain level of caravan comfort to a camper-trailer-sized package. Cub’s execution is quite good. The lounge is comfortable and the dinette table is highly adjustable up and down or around and around. It converts into a bed more simply than any other on the market I’ve seen. 

The downside of the forward-fold concept is the quantity and access of storage. Very little of the internal storage is easy to get to, and in truth there’s very little of it. That’s what happens when you put a couch in a trailer, sorry. There are hatches under the seats, but even they are limited by the slide-out kitchen and battery box across the back, plus, they’re not as easy to get to as a drawer. It’s the same in every manufacturers version, though. However, the Frontier has one unique features that makes it stand out – a series of pigeon holes under the foot of the bed which provide the only easy-to-access internal storage in any forward-fold I’ve come across so far.

Two-doors are never the most practical devices, but the 4 Series Coupe and Convertible duo make a decent fist of it for front-seat passengers. There are bottle holders in both doors and a pair of cupholders in the centre console, along with a large lockable glovebox.

The centre bin is, however, quite shallow, and houses the car's single USB port inside it. There is covered storage under the dash for smaller items, and a small rubber-lined tray that the current crop of phones has outgrown.

The rear seating in the Coupe is reduced to almost a formality, especially if the front seat passengers are tall and the front seats are set back, while the sloping roofline reduces head space quite considerably. A centre armrest contains a pair of cupholders, and there are small side pockets.

Rainy conditions precluded us from trying the Convertible's metal folding roof, but the rear seat space restrictions also apply here. Its 370 litres of boot space is roomy enough for a drop-top, while a clever lifting function raises the folding roof structure up by about 300mm to allow luggage to be stowed under the panels when the roof is down. Capacity drops, though, to just 230 litres.

The Gran Coupe, on the other hand, is the most practical car in the entire 3 and 4 Series line-up outside of the 3 Series Touring wagon. With a large, flat load area, and a hatch-like tailgate, the Gran Coupe can swallow 480 litres of gear with the seats up and an impressive 1300 litres with the seats lowered.

Face-level rear vents, more head and backseat legroom – not to mention the fact you don't have to squeeze into the rear past the front seat – makes the Gran Coupe a most useful device, and it's little wonder it's the most popular variant of the three.

The Frontier is quite good under tow. Cub designed and manufactures its own coil-spring independent suspension and has paid quite close attention to the balance and dynamics of the trailer. 

As it’s not overly heavy, it’s not a handful, even on the beach, and behind the Mitsubishi Triton I tested it with, it was barely a struggle. On the road, the camper is well behaved, easy to see over and around and because it’s not very long, it’s not very daunting.

BMW introduced a raft of tweaks to the 3 Series platform late last year, which have translated over to the 4 Series. The key addition across the line is BMW's two-stage adaptive dampers that feature a Sport and a Comfort circuit, fitted as part of the M Sport pack that comes standard on the 430 and 440, and is a $2600 option on the 420.

Larger 19-inch rims are fitted to the 430i and 440i cars, while the 420 gets 18s out of the box. It's possible to fit 18s on the more expensive cars, as part of the no-cost Luxury option pack that supplants the standard M Sport pack.

While our test was brief and held in less than ideal road conditions, the large-wheeled 4 Series really didn't enamour themselves to this author. There's a distinct lack of communication from the tyres and chassis through the steering wheel and your backside, while the combination of firm Sport shocks and large 19-inch wheels with narrow-section tyres made for an uncomfortable ride over country roads.

Sampling a 420i with the Luxury 18-inch rims, however, improved things immensely, with much better feedback and comfort that didn't come at the expense of handling.

One of BMW's strong points should be its steering, given all the 3 and 4 Series cars are still rear-wheel-drive… but it's not, unfortunately. The electrically assisted set up is far from perfectly calibrated, feeling too dull and digital underhand, no matter what the setting.

The pick of the bunch performance wise is – logically – the six-cylinder 440i. The turbo powerplant is potent from right down the rev range, with a muted yet still pleasing engine note permeating the cabin. The self-shifting mode on the eight-speed auto does a good job of keeping up as well.

The updated 2.0-litre four is a sprightly performer, too.
