The only nagging doubt I have with the DS4 is that cars that are suddenly in vogue can just as suddenly find themselves out of favour.
FAST FACTS Citroen DS4 DSPORT HDI auto Price: PS24,840 Mechanical: 163bhp, 1,997cc, 4cyl diesel engine driving front wheels via 6-speed automatic gearbox Max speed: 129mph 0-62mph: 9.
Alloy foot pedals add to the sporting interior of the DS4 and you can set the on-board computer to give you a digital readout from a window set in the middle of the conventional speedometer, a feature I often took advantage of because the pointer on the conventional speedo wasn't always obvious at a quick glance.
But while the smaller DS3 was conceived as a straight rival to BMW''s Mini, the C4-derived DS4 has no obvious direct competitors as it combines its coupe looks with a five-door practicality and the raised driving position of a SUV.
SpecCheck MAKE: Citroen MODEL DS4 DStyle HDi ENGINE: 1,997cc, 4-cyl diesel POWER: 163bhp at 3,750rpm PERFORMANCE: 0-62 in 9.
With its tall stance, deeply sculptured lines, panoramic windscreen and imposing DS grille the DS4 is a radical departure from the norm for Citroen.
Although it's a four-door, the DS4 looks like a coupe, with its rear door handles cunningly hidden at the top of the extended window frames.
A analise geoestatistica evidenciou que PG, DS1, DS3, DS4, r-UG2, r-UG3, r-UG4, r-UV1, r-UV2, r-UV3, r-UV4, l-RP1 e l-RP4 apresentaram dependencia espacial, ao passo que DS2, r-UG1, RP2 e RP3 apresentaram efeito pepita puro (Tabela 3).
I'm still trying to figure out how any vaguely coupe-shaped car with such an unusual relationship between length and height can emerge as pretty as this DS4.
This is the marque's mid-range offering, the DS4, a premium five-door hatch targeting customers that'll be new to a French manufacturer of this sort.
In this feature we explore the impressive DS model range, which includes the best-selling DS3 supermini, a past Top Car magazine car of the year, the luxury DS4, a prestige five-door hatchback with the unique style and grace of a coupe, and the sublime and well-appointed DS5 Crossover, a former Top Gear magazine family car of the year.
The new versions of the DS3 hatch and the slightly larger DS4 will be arriving in the UK in the New Year just six months after it was announced that DS was branching out of Citroen to become a car company in its own right.
