It isn't often that a model is introduced mid-way into the life of a car that specifically targets fleet drivers. Citroen has done this with the C5, a car that made its UK debut two years ago. The model in question is the new VTR – a badge that has helped sell thousands of Saxos over the past seven years, and also adorns sporty petrol and diesel Xsara models.

Other VTR cars in Citroen's range could be described as 'warm hatches' rather than hot ones. The C5 VTR struggled to warrant even this description, using a 117bhp 1.8-litre petrol engine and the 110bhp 2.0 HDi diesel tested here.

These are engines at the lower end of the C5 range, unlikely to set pulses racing. However, Citroen's PR people insist that in the C5 VTR they are providing the type of car that will sell to fleets.

It has low carbon dioxide emissions, an attractive price, room for all the family and a badge to show off in the company car park. So the C5 VTR comes across as a sheep in wolf's clothing. There are little details that give it the appearance of a high performance saloon, but there is an absence of substance under the bonnet.

There are 16-inch alloy wheels, bespoke blue/grey interior trim and colour co-ordinated seatbelts, leather-trimmed steering wheel, carbon-fibre effect inserts, anti-theft alarm and rear wash wipe.

Until the end of March the car comes with a £400 VTR pack, which includes chrome-effect mesh lower front grille and rear spoiler. However, you won't find a sports setting for the suspension as you do on higher-spec C5s – just the Hydractive 3 suspension which is self-levelling and reduces the car's ride height on motorways to improve fuel consumption.

On the road, there is little the C5 does badly.

However, its limelight has been somewhat stolen by the introduction of the Vauxhall Vectra, Mazda6 and Toyota Avensis, all of which have raised standards for the sector in their own ways.

Quality in the C5 isn't at the same level as the Avensis, it isn't as much fun to drive as a Mazda6 and it doesn't feel quite as solid as a new Vectra. However, it is roomy and comfortable, and while the soft suspension might not allow the car to feel as surefooted on challenging roads as any of the other cars mentioned above, it eats up the motorways without batting an eyelid.

As my week with the car progressed, it probably covered more than 600 effortless motorway miles, returning an average of nearly 50mpg, a key attraction for fleet drivers and managers alike.

Apart from all the things we take for granted in a modern upper-medium car (four electric windows, air conditioning, ABS with electronic brake force distribution with emergency braking assistance and six airbags), the VTR also has automatic windscreen wipers and headlamps as well as speed sensitive stereo volume.

As for the carbon fibre-effect trim, on closer inspection the design resembles fish scales. Perhaps a metallic-effect plastic might have worked better.

Straight-line performance is adequate while the brakes are in the mould of traditional French cars – instant, reassuring stopping power.

So the C5 HDi VTR proves to be an ideal high mileage motorway car, but I can't help feeling a little short- changed by the VTR badging. It might have been better to use it on the more powerful 2.2 HDi diesel or 2.0 HPi direct injection petrol car in conjunction with switchable suspension settings.
