History: Bedford CF design concepts [1966-1967]

Previously we learned that Bedford was working on a replacement for the CA since as early as 1956 with a CB prototype. In September 1965 a code name Bedford CD was already in the mock-up stage when Ford proceeded to release the Transit MK1 the following month. All of a sudden everything came to a stop to re-think the new van. 

In February of 1966 design work began on an all new CF, taking into consideration the new standards that the Transit set in the market. By August a target date of 1969 was set for the launch of the CF.
For the next 4 years, Bedford
would fall behind Ford with declining sales of the old CA, so the success of the new CF was critical for Bedford and also General Motors.
At that time it was also planned that the new CF would enter the US market to occupy the mid-sized van segment left open by the not so successful Chevrolet Greenbrier ("CorVan") that was discontinued  in 1965. The new CF chassis would also be used for a new Opel Blitz van to be launched in Germany in 1970.

Below are several design proposal drawings from 1966, including a Bedford TK replacement, a Opel Blitz replacement, Chevrolet Van and several variations of the Bedford CF, even a front wheel drive version!

"By the end of 1966 and early in 1967 Chevrolet were dropped from the programme and a separate Opel model had been rejected by the GM Board, instead Opel would continue to limp on with the Blitz B until the 1973 model year when it was planned to be replaced with an Opel badged version of the Bedford Van.
The final design was a semi forward control van that was longer, even in SWB form, and considerably wider than the CA and crucially its critical load dimensions were better than the Transit. Both Leo Pruneau and Wayne Cherry worked on the design under the guidance of David Jones and it showed, when the CF was launched it had something that neither the Transit nor any of its major competitors had – style and bags of it too. There were some corporate GM design cues included but they were all positive for once.

Mechanically the new van used very few carry over components from the CA, the 3 & 4 speed gearbox was the main one. The engine choice went from 2 to 4 and included the new 1599cc & 1975cc slant 4 OHC engine that was just about to be launched in the Vauxhall FD Victor along with a choice of 2 Perkins diesel units, the smaller version was previously offered in the CA. However, this diesel option could have been very different because the development of the slant 4 OHC unit also included diesel versions. The fully independent front suspension was also new and was a beefed up adaption to that would be used in the Victor FD.
Two wheel base lengths were designed – 106" & 126" – compared to 90" & 102" for the CA, also the weight range was planned to be widened to run from 14cwt to 35cwt, the largest 35cwt would use a modified TK back axle with twin rear wheels for the first time on a Bedford light van.
There has been much discussion surrounding why the van was named CF and not CE (there had been CB & CD projects), well the answer is because of the amount of components from the (F)D Victor it was decided to jump straight to C(F)."

History: 1965 Bedford CD Concept Van

"BEDFORD CD FORWARD CONTROL VAN SCALE MODEL 13.09.65 D-65589 © GM ARCHIVE"

The Vauxhall Vauxpedia site has dug up some interesting new historical details and archive photos from GM concerning the history of the Bedford CF.

The 1952 Bedford CA was the best-selling light van in the UK up until 1965 when Ford launched the Transit MK1. The Transit instantly became leader in the market while the CA sales plunged. Bedford took 4 years to finally respond with the launch the CF and recall the title.
Bedford had been working on a replacement for the CA since 1957. In a previous magazine article from 2004, we learned about the prototype Bedford "CB".


Now we learn about the Bedford CD, which was the replacement van that was being designed in 1965 right when Ford launched the Transit. Here is the story and archive photos:

"In 1965 Bedford had two distinct van ranges, the relatively small light weight semi forward control CA and the heavy weight normal control TJ introduced in 1958, but was basically an updated version of the post war TD range, was by this time a slow seller in the UK but popular in export territories such as Africa, it was however quite successful for ambulance conversions in the UK. The new replacement van would need to cover both the CA & TJ van ranges, but it didn’t stop there – in Europe Opel had launched the Opel Blitz B in 1965 and proved underwhelming sales wise, Opel had been the number one seller of commercial vans in Germany in the early 1960s but had been on a downward spiral ever since and so the planned Bedford replacement would also encompass a Blitz replacement as well. As if this wasn’t enough in the US Chevrolet had launched the unusual rear engine “CorVan” in 1961 based around the Chevrolet Corvair car mechanicals (not a wise choice) and then in 1965 launched the much larger G Series Van and phased out the CorVan in 1966 which left a gap for a smaller van to sit below the G Series so in the very early design stages Chevrolet were included in the plan.
Even before the launch of the Transit, Vauxhall had started preliminary work on a fully forward control van coded CD in August 1965, however this never got beyond the scale model mock-up stage, completed on 13 September 1965, before a complete re-think of the parameters for a CA replacement were put forward following the Ford Transit hit the market in October 1965."

History: The Bedford CB



























MISSING LINK:
BEDFORD'S SHORT-LIVED CB

People have often wondered why the successor to the long-running and popular Bedford CA was called CF. We still don't have the answer, but BARRY HARVEY, who worked in the Vauxhall experimental department, recalls some short-lived work on a CB project.

Before the Ford Transit conquered the market there was the Bedford CA. Bedford's long-running 15cwt van in production from 1952 to 1969 and for most of that time was Britain's most popular small commercial.
The CA's replacement was called the CF, so what happened to the CB, the CC, CD and CE?

Little has been written or said about this question, leading to the general conclusion that the CA was so good that various proposed replacements were considered to be no improvement until Bedford got to the letter F.
Whatever the truth of that, we now know that Bedford certainly produced a possible successor to the CA, as the photographs on these pages show.

Whether the public would have liked it is open to question. The styling of the CA was certainly American in origin but the overall lines were not extreme. In fact in 1952 they probably seemed attractively advanced, as indeed was the case.

The CA had independent front suspension, an up to date engine, from a Vauxhall Wyvern car, and an all-steel body mounted on a separate chassis.

The competition from Ford and Morris were quite old-fashioned designs in comparison and Austin's nearest competitor, the K8, more modern than the Ford or Morris, was designed for bigger loads.

Judging by these pictures, the CB was a much more radical American design than the CA. The high front panel and shallow windscreen, the low mounted grille, the dog-leg windscreen pillars and the sloping tail going in several directions at once, might have been too much for the more restrained British van buyer.

Even the name on this prototype is formed in a typical American magazine-style typescript that would have seemed quite foreign to British eyes.

As Bedford and its parent company, Vauxhall, were owned by the American company General Motors, it is hardly surprising that there should be a Transatlantic influence on what might be produced in Luton and Dunstable. The Vauxhall cars of the Fifties were unashamedly American in their styling.

Was this potencial replacement for the good old CA a scaled-down version of a Chevrolet or General Motors van produced in the USA?

When the CF appeared in 1969, its style too was inspired by General Motors' American products, but, like the CA, it was sufficiently restrained not to look out of place in Britain.

Whatever the origins of the intended CB, it was a short-lived project and the senior engineers of the time are no longer with us.

One man who was there, as a young trainee, is Barry Harvey, now retired but secretary to the Vauxhall Owners Club 1903-1957. He writes: 'I did a five-year apprenticeship at Vauxhall, starting in 1954. The first two years were spent in the Apprentice School learing machining, welding, sheet metal work, drawing, etc, with day release for college.

'After two years we were placed in various departments in the factory to continue training. I was lucky to be sent to the Experimental Division of the Engineering Department where I worked in various jobs for the whole of my 40 years' service.

'In 1956 or 57 (I think), during my spell in the Running Shop, where all lash-up, test and prototype cars, vans and trucks were built, I worked on the build of the CB van, the intended successor to the CA, which had been launched in 1952.

'After we had built about five vans, left drive and right drive, the project was suddenly shelved. Rumour at the time was that the van resembled too closely the newish Ford Thames 400E and Vauxhall would not risk being accused of copying the design.

'But the new Bedford was not too similar. Maybe it was the Ford Taunus van from Germany that Vauxhall was concerned about.

'The CB vans were parked up for some time, then brought into the workshops one at a time and scrapped. That was a shame, but the CA soldiered on successfully for many years after that.'

After all his years in the front line of Vauxhall-Bedford development it is hardly surprising that Berry has recently bought a rare surviving CA panel van which he is restoring …
