BODY TORQUE…
AND THE CITROËN C3
Back
in the eighties when my mate Leee John was topping the charts with Imagination,
body torque - the amount of twist and distortion transmitted to cars by road
and power variations was far from being just an illusion. (See what I did
there?)
In
many cases it was bad enough to be visible to the naked eye of those not even
in the car in question. Especially as it left a junction and crossed
conflicting cambers, it was surprising that the doors and tailgates didn’t pop
open, so extreme was the parasitic response by structures now devoid of the
traditional ladder or platform chassis.
The
mass migration to transverse engines and front wheel drive had not really
caught on across all manufacturers then as it has now. Rear wheel drive cars
continued to supply undirected force and their longtitudinal engines whipped
through every joint and component from front to back in their direction of
rotation, further exaggerated by distorting transmission shafts carrying the motion
to the back axle.
While
all these forces of physics were loose in the contraption, a certain amount of
give in the bodywork was pretty much a necessity. Suspension had to do its best
to keep the wheels on the ground, so body panels needed to absorb shocks that
might otherwise fracture the windscreen, while keeping construction as
lightweight as possible for performance and fuel consumption.
The
steel chassis was not about to make a comeback, although most of the parasitic
actions could be mitigated by the move to front wheel drive. Escorts, Golfs and
British Leyland’s Minis, 1100s, Allegros and Land Crabs still coexisted with
Sierras, Granadas, Passats and Cavaliers whose transmissions and structures
could seriously compromise their theoretical abilities on paper.
Our
local police force had two or three SR4i Fords and wrote them all off. I drove
a couple and could readily understand how. The architecture and damping was in
no measure equal to the power and performance of the 2.8 litre engine.
Other
improvements came in the form of the tubular backbone and ring of steel
conceived by Citroën for their BX replacement Xantia. A central chassis member,
akin the the arrangement Colin Chapman used for Lotus sports cars was filled
with lightweight plastic material that prevented the tube from twisting in
response to parasitic movements. In conjunction with the car’s
computer-controlled hydractive suspension, this allowed for accurate monitoring
of ride that didn’t threaten structural unity of the car.
I
have personally seen two cars of similar vintage rolled on the same section of
the M20. The other car’s passenger compartment was flattened. The Xantia
retained its structure.
Twenty
odd years on comes another major step forward in body structure as it dawns on
everyone that properly designed suspension doesn’t need the safety margin of
‘give’ in the rest of the car.
This
is especially cheering because the lamentable state of our roads as a result of
neglect and mismanagement takes an ever higher toll on our cars, with broken
springs and shock absorbers becoming commonplace. Little did the Beatles
predict in those times of optimism and solvency that we would now have enough
holes to fill the Albert Hall, the London Arena and the NEC several times over.
Already
we have noticed some benefits, notably in smaller cars that are more vulnerable
to outside influences than heavy limos - Kia and Suzuki have both made great
strides and larger cars such as the Vauxhall Insignia are offering exemplary
levels of comfort.
But
the difference can be best seen in isolation in Citroën’s great-looking new C3.
Much more distinctive to look at than its predecessor, it benefits from a
number of the innovations announced as part of the Citroën Advanced Comfort
package announced some months ago, though it doesn’t yet feature the new
suspension units.
The
previous C3 offered a good ride compromise between certain parameters. When
these limits were reached, although it lost no grip or control, it became upset
- especially on country lanes or boot fair fields. You knew instinctively the
maths had been done, but something wasn’t working as it should.
It
becomes clear on the new car what that something was; not the tuning of the
suspension, which remains the same, but the degrees of resistance offered by
the architecture of the car in more extreme circumstances.
Although
manufacturers are naturally keen to tell you in advance what to find when
driving one of their cars, I have always preferred to try the thing ‘blind’ and
see what actually happens. I knew the Advanced Comfort package was in the
offing and a number of Citroën dealers were alrady tumpeting it on current
models. On first driving the new C3, I thought it was an improvement, but
couldn’t make up my mind that any change had occurred in the underpinnings.
The
improvements, other than taking advantage of the opportunity to strengthen the
body shell, consisted of the other factors of the package, which include seats
dialled to the best resonance for the car and interior fixtures and fittings of
comparable quality and solidity to the bodywork.
The
difference is immediately appreciable and gives the car a real sense of
permanence and dependability. That being said. not only does it not achieve the
promises of the full CAC, but also falls back on a strange temporary solution -
what seems to be an abandonment of damping in general.
Bizarrely,
this seems to be surprisingly successful, though it can certainly be caught out
in a big way. I feel that a set of the ‘inertia’ dampers fitted to the 2CV, Ami
and Dyane would be an ideal solution, just as it was fifty odd years ago.
The
original C3 always put me a little in mind of Grüber’s little tank in ‘Hello,
hello’. It was distinctive, but wasn’t a standout visually. It’s replacement
lost the distinctive and became almost invisible. But the new car builds on a
more fun and confident look that began to characterise the range with the C4 Picassos
and the little C1. Especially in the colourway our car came in - bright red and
the new high white - it makes no apologies and even makes the likes of me look
cool and happening.
It
further benefits, of course, from the brilliant 1.2 litre Pure Tech petrol 3,
which has just been voted engine of the year yet again. Drive one and you’ll
see why.
A
long time diesel devotée, despite the muddled nonsense talked by the
government, I was dubious when I was delivered a petrol engined C4 Picasso some
months ago for a trip to Devon. When I further discovered that this big people
carrier was expected to respond to a 1.2 litre engine, my internal organs sank.
But
astonishingly, it was an absolute joy to drive, performing more like a hot
hatch, and even delivering sufficient power to pick up speed on inclines in its
equally surprising sixth gear. What’s more, despite a lot of hill work around
Torquay, it did both ways on a tank of fuel - equalling the 1.6 HDi diesel, but
adding the fun factor that comes from the free-revving three pot.
In
the C3, joy is potentially even more unconfined, though the ratios are slightly
different and the baby isn’t allowed a sixth cog.
The
look of the car and the fun factor are very much the main attractions. If you
are a Citroëniste by nature, you will enjoy its balletic pogress and its
singularity. Nothing the neighbours have will look like it, or make them smile
in the same way.
It’s
not perfect. Who thought it would be? But it’s good value and good fun.
It
might not be better (however you define that) than Frankenstein’s Mini or the
latest Fiesta, but it’s more noticeable, and its power unit is the best in the
business.
Leee
is wowing them with his Retropia tour and C3 shows us through expression, not
aggression that happiness is just a state of mind.
