IF IT AIN’T BROKE... Apart from meeting the latest emission levels, Daf Trucks has resisted the urge to fi x something that wasn’t broken. CM renews its acquaintance with the evergreen CF85 tipper at Euro-5.

T he Daf CF85 is as about as successful and versatile a truck as you could hope to fi nd. It’s an award-winning fl eet
tractor but it also makes a drawbar prime mover, and is the industry’s leading four-axle chassis cab.
Not that it stands out in any particular area. The CF85 is neither the lightest vehicle in its class, nor the most frugal, nor the cheapest. But it’s a reliable, seasoned all-rounder with a long production history and – perhaps more importantly – is known to have decent back-up.
The 85 reached the UK in May 1993 with an 11.6-litre straight-six lump. A Euro-2 model arrived in 1996 and by 1998 we had the 340hp XF variant, still based on the 11.6-litre design. In 2001 the CF was revamped, gaining a bigger cab.
Two years ago we tested the Euro-3 version (CM 17 February 2005) and it’s interesting to compare its spec with the latest model featured here.
The Euro-3 engine had grown to 12.6 litres, developing 375hp with 1,750Nm of torque, and drove through a ZF 12-speed automated AS-Tronic box. With a full 340-litre tank and 75kg driver, that CF85 had a kerb weight of 9,302kg.
The SCR Euro-5 engine is still a straight-six but thanks to a longer stroke it has grown again, to 12.9 litres, developing 408hp with 2,000Nm of torque. The AS-Tronic transmission is unchanged, as is the 340-litre fuel tank and CM’s notional 75kg driver. But a 15-litre AdBlue tank and bigger engine have helped push up the kerbweight to 9,412kg.
The list price has risen too: meeting Euro-5 has pushed the cost of a basic chassis-cab to £89,430 (our test vehicle came with a Rouse aggregates body featuring an air-operated tailgate and electrically powered sheeting system).
So what do you get for the extra cash? It depends who you talk to – but if your chosen Euro-5 truck has on-board diagnostics (OBD), the rewards will include a Reduced Pollution

And the LEZ is set to become a major factor for tippermen because of the London Olympics, with major construction projects up for grabs from next year right through to 2012 which will only benefi t operators running Euro-5 motors.

requires 400rpm less to achieve full power –and we ran it at 85km/h, which is the new motorway speed limit for all CM test vehicles.
This Daf being in the SCR camp, there is also AdBlue to take into account. Over 259.5km we used 4.7 litres of the blue liquid, equating to 5.3% of the diesel used.
CM records AdBlue consumption by its cost per 100km – and at 40p/lit (ex-VAT) that works out at 72p/100km. With diesel at 80p/lit the overall running cost for the Euro-5 CF85 comes to £27.76/100lit. With no EGR model to compare it with, we can only refer to our previous tests: the Euro-3 Daf CF85 cost £28.08/100km, while the Alpha and Kerax, which boasted better fuel economy when we tested them, would prove cheaper to run.
When it comes to productivity, the Euro-5 Daf is well matched to its Euro-3 predecessor.Overall the latest model costs more and weighs more but is more fuel-
effi cient – and in any case it will soon be the only version you can buy from new.
On the road Two years ago CM lauded the 375hp engine for the way it propelled 32 tonnes around the test route; not surprisingly with 408hp on tap power was never an issue. The only real challenge we presented the CF85 with was Edge Hill and its infamous U-bend half way up.
The Euro-3 version completed the climb in 2min 10sec, mostly in fourth (though it did change from fi fth to third then back to fourth in the space of three very long seconds and approximately three yards. That, as you might have guessed, was in auto). The Euro-5 model was seven seconds quicker and held on to sixth gear at just above 1,100rpm. This time the gear was held in manual to prevent a repeat of the previous test.
As long as you are consistent with the
The cab is similar to before but with a few modern appliances thrown in. These include electrically controlled wing mirrors, aerodynamic side collars, air-con (at last – a Daf demo truck with air-con), aluminium disc wheels and an MX engine brake. Warranty is also unchanged at two years.
Productivity We’ve looked at what the initial cost of Euro-5 technology might mean on the books, but we were keen to see how it affected day-to-day running costs. Back in 2005 the Euro-3 version achieved 8.05mpg overall; the latest Euro-5 model recorded 8.36mpg. Its A-road fi gure was on a par with the 2005 model but over the short motorway section the Euro-5 engine was thriftier by an impressive 9%.
The characteristics of the Euro-5 engine clearly helped here – it has 33hp more power and 250Nm more torque at its disposal, and

throttle, the AS-Tronic will change gear in all the right places. But up at the top end it’s advisable to switch to manual – and remember that you have done so, otherwise you’ll receive a sharp reminder when you try to pull out onto a roundabout. You’ll need training to get the best out of the CF85’s AS-Tronic transmission, and allow some time to adjust to the buttons, tricks and perceived advantages the automated box gives over a manual.
The ride is smooth and steering is exemplary out on the road; the Daf swings into and out of roundabouts with ease.
Cab comfort If you still have our Euro-3 roadtest from 2005 please refer to it because the cab is virtually unchanged. Yes, the new model boasts air-con, but try asking the demo driver to switch it on and the reply will be short and sweet (understandably in a market as competitive as this, where every scrap of fuel counts). The electric wing mirrors are helpful when you fi rst jump in, but once they’ve been set up the ease of adjustment is irrelevant unless you hit a branch, oncoming mirror or weighbridge gantry.
The day cab offers enough space behind the seats for coats, bags and spare hi-vis clobber, and is roomy enough for drivers who rarely venture 50 miles from base. If you need 40 winks during an arduous day the seat offers a little room to recline into for a power nap. Cross-cab access isn’t really an issue unless you fancy a challenge, and the absence of a clutch pedal leaves enough room by your left foot to change position and avoid deep vein thrombosis.
The driver’s mirror – the long one that lines up the offside of the truck – remains a bugbear because its position on the arm blocks out the 45º view from the driver’s seat. Most of the time this isn’t an issue, but when entering roundabouts it blocks off two vital areas: traffi c emerging from your right, and vehicles already on the roundabout heading for your exit or the exit to your left.
Traffi c has to come out of the blind spot before you can make a decision to maintain momentum or pull up. Yes, it’s possible to move forward or lean back to get a better view, but during a long shift that will become a real hassle.
There is a trend for road builders, encouraged by local authorities, the Highways Agency and the Health and Safety Executive, to attempt to slow down traffi c by blocking the view to the right at roundabouts with bollards, hedges and the like. This leads you to slow right down before making a split-second decision

about pulling out – wasting fuel and shortening the driver’s fuse.
Improving the view into roundabouts gives drivers more time to make the right decision without grinding to an unnecessary halt. With the EU demanding legislation fi tting trucks with more blind-spot mirrors, we have to wonder why manufacturers haven’t done anything about this obvious blind spot looking forward – especially when it blocks such an important line of vision.
If the mirror was lowered by just a couple inches you would still have the view down the side of the truck as well as that all-important 45º view into roundabouts. ■

OUR VIEW
The road transport industry has been busy adjusting to digital tachos and ever tougher emissions limits. But while it has updated the CF85’s driveline, Daf has wisely left the basic structure well alone so the shell of this vehicle is identical to its Euro-3 predecessor we tested in 2005.
The cost per 100km gives an indication of what Euro-5 might mean at the pumps, and manufacturers are keen to highlight potentially improved residuals which could offset the higher list prices associated with Euro-5.
As a workhorse, the latest CF85 is hard to fault simply because it does everything well. The only factor that might put off a potential buyer is its list price. But with the Euro-5 deadline next year this is an issue you won’t be able to avoid when picking a new vehicle. If you want a share of the Olympics bonanza, this is the sort of vehicle you should be buying now.
