The interior is just as dramatic. The driver is hemmed in by a genuine cockpit feel, thanks to the high centre console, deep dashboard and roof-mounted switchgear console. The interior also relies heavily on metal trim, which appears, among many places, on the rim of the flat-bottomed wheel, around the instrument bezels and on the unusual, but effective, ‘shark’s tooth’ switches on the centre console.
The 161bhp 2.0-litre diesel engine, driving a conventional six-speed automatic gearbox (the manual version will cost about £26,000 in the UK), is smooth and willing, with an easy and pleasant gait.
The combination of the higher – and very relaxing – driving position and the car’s refined and long-striding powerplant give the DS5 a flavour of the classic French ‘Grand Routier’ cars that were optimised to waft unerringly across Europe. This is a notably refined car when cruising on part-throttle.
Downsides include the way the double A-pillars and the low-mounted rear-view mirror obscure the view through the shallow windscreen. But the real problem with this DS5 is the shockingly bad ride over very rough surfaces and potholes.
On good surfaces, the ride is more than acceptable, but the way it suddenly deteriorates over potholes and broken surfaces made more than one driver curse out loud in surprise during our time with the car. The amount of noise that is transmitted into the cabin is also unusual.
This problem goes beyond the 18in wheels and low-profile tyres on the test cars. But with a few months to go before the DS5 goes on sale in the UK, there may be time to rid this attractive car of such a significant flaw.
The Hybrid4 version of the DS5 gets a multi-link rear axle and this helps to improve the ride over rough surface a little.
The DS5 Hybrid4 has the technical prowess to back up the styling, offering a Co2 rating of 99g/km, a potential combined thrust of 197bhp and 369lb ft, part-time all-wheel drive and the option of part-time zero-emissions running, when just the rear wheels are driving the car via battery power.
Should I buy one?
The DS5 is a genuinely stand-out, original design: striking, practical and thoroughly likeable. But Citroën needs to smooth out the rough-road ride as a matter of urgency.
