Read the Practical Motorhome Karmann Ontario 670 review – is it worth the outlay?

Design

Karmann’s unashamedly design-led approach is clear 
in the angled, tapered overcab shape. Its all-silver paintwork is eye-catching, as is its height of 3.22m. This is largely due 
to a 40cm-deep double-floor cavity which houses all the supply lines and heating trunking, and provides lots 
of additional storage space – perfect for all-season touring.

The beauty is not just skin deep, either: underneath is an unusually high level of build quality, with the sandwich walls fixed to each other with aluminium profiles. A colour-coded awning is a cost option.

The only exterior blemish 
is on the habitation-entry side: 
the electric step up to the 
60cm-wide entry door requires the sill to be cut crudely away, and appears unfinished.

On the road

With an AL-KO chassis lowered by 22 cm, the Ontario felt stable on the winding, cambered roads of our test drive, despite its high sidewalls. The 2.3-litre engine is standard but we had the 3.0-litre upgrade.
Payload on the standard 3500kg chassis is 400kg, with the option of up-rating to the 4000kg Heavy chassis.

The overcab, which protrudes 110cm from the Ducato windscreen, is the biggest 
we've ever seen and it is clearly visible from behind 
the wheel.

A good level of standard cab equipment, including driver and passenger airbags, single-key central locking cab and hab doors, was complemented in our test ’van by the optional Fiat Comfort Pack of cab air-con, cruise control, electric mirrors, and cab swivel seats with armrests and lumbar support.

Lounging & dining

The four-berth 670 has an 
L-shaped lounge and side sofa up front with transverse, rear bunks over the garage storage space at the rear. There are belted forward-facing seats 
for two rear passengers.

From the curtain-separated cab floor it is a step up to 
the living quarters (thankfully, the overcab bed base folds up to a vertical aspect).

As with many German-built ’vans, the table is fixed in place on its sturdy, free-standing leg, with the table-top mounted 
on sliders. The optional TV is supported on brackets, with a good view available from the cab seats and ‘L’ part of the lounge.

The two-tone furniture design throughout, of ‘Vermont walnut and white stream’, is attractive but makes for a rather gloomy interior, especially given 
that there is only one lounge window. There are, however, directional reading lights on 
a slider over the L-shaped sofa.

Kitchen

It’s a second step up into the kitchen area (see ‘Lounging and Dining’ section) but there’s still more than 6ft of headroom.

Part of the UK specification includes an oven and grill above a 117-litre Dometic fridge. The three-burner hob lacks spark ignition, though. Storage underneath the worksurface consists of an acrylic-faced wire veg rack 
and moulded cutlery drawer.

There’s an extractor fan and light over the hob, just where 
it should be, and the circular, steel sink is deep enough for 
a kettle, but has no drainer.

Sleeping

The lounge in our test ’van 
did not have a double bed (although it is a no-cost option).

Both rear bunks have slatted bed bases and substantial sidelight windows. The upper bunk mattress can be propped open by a support leg to allow access to a mini-storage space beneath (there is a separate access flap for this, too). 
There is no access to storage space beneath the lower bunk, apart from outside the ’van. We were surprised to find 
no partition or privacy curtain for the rear bunks.

The overcab bed, with a privacy curtain, has two single mattresses, and a box at the front end for odds and ends. Headroom is a generous 72cm. Twin spotlights and a single window illuminate the area.

Washroom

The bathroom door hinges through 180 degrees, and opens onto 
a Thetford C200 cassette toilet. Downlighters sit above a smallish basin, and there is vented heat at a low level.

The shower is a sealed, plastic unit with two drainage plugs 
in the base, and ventilation above. Overall, the washroom is functional and usable.

Storage

The lower of the two rear bunks is hinged to allow bikes to be stored in the rear garage space, (the entry door measures 120 x 70cm). There is also that cavernous double floor, and our test ’van was fitted with 
an optional bike rack, mounted 
on the rear panel.
The fresh-water tank sits beneath the forward-facing part of the lounge, and that somewhat restricts under-seat storage space.

The plentiful number of overhead lockers all have sturdy, domestic-style hinges and noise-dampening interior beading trim.

Verdict

Karmann-Mobil is a welcome and stylish addition to the mid-range market. Anyone looking for a motorhome that stands out from the crowd could do a lot worse than start their search here. However, with all the extras fitted, the total price of this test model 
is a hefty £51,662.
