BX update

Fourwheelsteer’s faithful if sometimes fallible Citroen BX has received some long overdue care from the good people of Preservation Garage Services (PGS) in Warwick. The same people who did such a good job of looking after my old BX performed a service and changed the cam belt and the car seems better as a result. There may be nothing measurable – it is too early to see if fuel economy has improved and I’ve not tried to measure acceleration or top speed – but the engine sounds sweeter and feels more willing.

A 1,360cc engine in a large-ish hatchback body might not seem like the perfect recipe for driving enjoyment but the BX only weighs 900kg so the 72bhp motor does not have to work too hard. The power unit is abetted in its task by a five-speed gearbox with ratios perfectly judged to make the most of the engine’s efforts. Although the overall gearing feels rather low – there is no rev counter to verify this assumption – there are no noticeable gaps between gears. The result is that there is always a gear that is right for the occasion.

Sadly, the merits of well-spaced gear ratios are being abandoned by manufacturers for the sake of fuel consumption and carbon dioxide figures. Several times this year I have read boasts of making the top three gears in a five-speed gearbox higher whilst leaving first and second alone – what can this do except leave a big gap between second and third gear? It probably fits the strictures of the standard test procedure perfectly but our roads are not standardised and on the road there will be times when the choice is stream or strain, neither of which is ideal.

This isn’t a new problem; the industry has been producing oddly geared cars for as long as it has been producing cars but it can make a big difference between enjoyment and frustration when driving. If you want a car with perfect gearing all the time surely you need some sort of continuously variable transmission.

Thoughts on this week’s Autocar

If I understand these things correctly a blog should be topical and updated regularly. Being topical isn’t necessary, I suppose, but it is interesting that the more I write the more ideas come for future entries – which is great for ensuring a steady stream of entries.

Every week I read Autocar, it is a good way to get an overview of the important motor industry news and it is a good read to boot. It is interesting to see what stands out. In the 2007 Green Grand Prix a passing mention is made of Mercedes’ BlueTec low emissions engines. It is interesting that Mercedes have focused on reducing hydrocarbon, nitrous oxides and particulates at the expense of slightly higher CO2 emissions. Because that approach isn’t compatible with a CO2 based tax system BlueTec isn’t coming to the UK. So is an obsession with carbon dioxide actually harming the environment by increasing emissions of other pollutants?

Green Driving

The environmentalists are at it again. The world is under threat because some people choose to do 80 on the motorway rather than the legally permitted 70. This apparently produces a third more CO2 which will cause the Earth to warm up until it can no longer support human life. Or it’ll cause more extreme weather and hot places will get hotter while cool places get cooler. The more you listen the clearer it becomes that no-one knows what will happen but everyone is happy to predict doom and gloom.

None of the news reporters, none of the lobbyists, no one at all has paused to consider what they are actually saying. Man made emissions account for a small amount of atmospheric CO2. Of that the UK is responsible for a tiny percentage. Transport might account for a large proportion of the UK’s carbon dioxide but remember transport is more than just cars and how much CO2 can be accounted for by cars exceeding the motorway speed limit as opposed to crawling through towns? The term “a drop in the ocean” barely seems adequate to express the magnitude the saving if the environmentalists get their way.

Anyone who makes long motorway journeys must have noticed that they are about the most economical (in terms of mpg) car journeys while driving in town use the most fuel. Where safe I treat the motorway limit as a guideline rather than an absolute rule (as most do). On long journeys it saves time, which is far more important than saving money. The amount of fuel needed to maintain steady motorway speeds is tiny even if doing 80mph produces a third more carbon dioxide than 70 (itself an unsound, one size fits all approximation) it is a third more of a tiny number.

Rather than trying to slow down motorway traffic the campaigners would be better advised to look elsewhere to make changes. If fuel consumption is at its worst in urban environments why not look at what can be done there to improve matters? Rather than having traffic stationary, burning fuel and going nowhere, try to keep the traffic flowing. Urban air quality would improve, people would be less frustrated, fewer precious resources (fuel and time in particular) would be wasted and less CO2 would be released into the atmosphere. Steve Cropley said much the same thing in this week’s Autocar. Of course if you want to stick to 70mph on the motorway feel free; just remember to keep left so other traffic can flow freely past.

C-Crosser makes me cross

I like Citroëns. I hope that is clear from my previous posts; as well as the C6 and my current BX I have fond memories of the C5 V6 (now sadly discontinued), the Visa and the iconic 2CV. The firm has blotted its copybook with the Xsara Picasso; an absurd vehicle good for nothing.

Now Citroën are jumping on the small 4x4-cum-mpv bandwagon with the C-Crosser, the result of a joint venture between PSA and Mitsubishi. I don’t blame Citroën for making what people want to buy. What I do object to, without quite knowing why, is the cloying emphasis on how kind it is to the environment.

Maybe if there was something identifiably Citroën about the C-Crosser it would be less annoying. Something minimal, lightweight, practical and go-anywhere - like an updated 2CV - would be brilliant. Sadly I don’t think the market wants such a car. Instead it wants soft-feel plastics, MP3 player compatibility, satellite navigation, two dozen airbags and low official CO2 figures for cheap road tax.

Citroën nearly went bust making the cars people should have wanted because the world was too dumb and too cautious to appreciate them. Sometimes, when I think of the Xsara Picasso and now the C-Crosser, I wonder if I wouldn’t be happier if the firm hadn’t survived the 1970s.
