Currently reading: Throwback Thursday 1967: The future of electric cars and the Ford Comuta concept
Our thoughts from 1967 on Ford's tiny Comuta electric concept car, the future of electric vehicles as a whole and what would eventually replace the internal combustion engine

Although alternatively fuelled vehicles (AFVs) seem modern, the technology they employ is, in fact, ancient.

‘The death of the internal combustion engine’ is a topic that has been discussed within the automotive industry since its very inception, but, until very recently, that discussion may as well have been held in an echo chamber.

Now, nearly every major manufacturer is being proactive with replacing petrol and diesel, and significant sales growth is coming in.

But it has taken a while. If you were to order AFVs by their current likelihood of becoming the future of mainstream personal transport, I would argue the resulting list would go something like this: Electric batteries, hydrogen fuel cells, hybrids, plug-in hybrids (PHEVs), biofuel, compressed natural gas (CNG).

However:

CNG has been used to fuel vehicles since as early as the 1930s; the first ethanol (biofuel) engine was built in 1824, and the Ford Model T (1908) could use it, gasoline, or a mixture of both; Porsche built the Mixte PHEV in 1899; The Armstrong Phaeton of 1896 had a petrol engine connected to a dynamo flywheel, which charged a battery; one of the world’s first internal combustion engines, the de Rivaz of 1807, was hydrogen-powered, and that was applied to a car a year later; and experimentation with electric cars dates back to the early 1800s, with experimental electric cars appearing as early as 1867.

Back on 15 June 1967, we here at Autocar were having the very same thoughts about the future of automotive propulsion, although at a time when AFVs were markedly less prevalent, and we envisaged Wankel petrol engines, gas turbines or steam engines to be future possibilities.

“The car engine of the 1990s may not yet have been conceived,” we said. Well, it’s 2017, and we’re still waiting for something else, so it looks (for now) like electricity will be the one – as it did back then, as we took a view on Ford’s tiny electric Comuta prototype, “a practical vehicle of limited performance, designed for restricted use in cities, rather as electric golf buggies are used around a particular golf course”.

A box on wheels little bigger just half the size of a Ford Cortina, yet in which four people could just about squeeze, the Comuta was powered by four 12v 18amp lead batteries, which gave a range of 37 miles and a top speed of 37mph. Just like a milk float (of which there were nearly 50,000 in the UK by 1970).

“Ford’s announcement of the Comuta is mainly to put the present state of the electric car into perspective,” we said. “It is also to show that Ford is interested in tackling the problems posed and are pleased to let the public know about it.”

We could certainly envisage a future for the Comuta. “Suppose an area in the centre of London were closed to all road traffic as we know it,” we said. “The authorities then place an order for 50,000 small electric public vehicles to transport people from and to perimeter garages to destinations and back.

“We do not doubt that something suitable could be produced at not too high a price, within five years. The same basic vehicle could be van, taxi and self-drive car with maybe coin box payment.”

That electric cars produce “no exhaust noise, virtually no fumes,” and were far more reliable than internal combustion engines at the time also appealed – although electric cars were “not very quiet” back then. Much the same reasons as we laud them now, unsurprisingly, although the latter statement is now reversed.

However, the issues surrounding electric cars which present themselves now were naturally even more obstructive in 1967, given the technology available. The only feasible electric car battery was a lead-acid one, as more sophisticated units, such those made from silver zinc, achieved a much better power-to-weight ratio, but were far more expensive to produce and hugely increased running costs.

Now, of course, we have the advantage of lithium ion batteries, which were invented in the 1970s.

And while there were suggestions of Ford experimenting with sodium-sulphur batteries – estimated to kick range up to 200 miles, amazing even for nowadays – little came of it, and after having spent some £10 million (around £160 million today) on researching electric car technology, Ford withdrew to ‘await a breakthrough in battery technology’ just a few years later. Familiar wording!

“With the exception of the electrical control equipment, electric car design has progressed very little in some 50 years,” Autocar lamented back in 1967.

“Now a great deal of research is in hand, particularly on power supply, which could lead to rapid developments.”

Alas, Autocar and Ford’s suggestion of having Comuta-style cars commercially feasible by 1977 came nowhere near fruition, and we still await a true challenge to the petrol and diesel now, another 40 years on.

But it now looks now more likely than ever that in half a century’s time, we’ll look back at fossil fuels as a long-gone anachronism. So here’s hoping that nobody will be writing a Throwback Thursday about this very article in 2067 to a similar tone as I just have.
