Ah yes, the accident. The 8.8-mile Spa-Francorchamps was an exhilarating but daunting place to race the 1.5-litre F1 cars. Cliff, on a quick lap in practice for the 1961 Belgian Grand Prix, was pressing on in UDT-Laystall’s Lotus 18 when he arrived at Blanchimont too fast. “I got as much opposite lock on as I could, but it was becoming obvious it was going to spin. Then the nose of the car went onto the grass, and it just flipped over. “The first roll almost threw me out, but my lower legs were trapped by the steering wheel and got crushed as the car went over.

“Had I not got thrown out on the second roll, I would have been killed because the car was a complete write-off. As it was, along with the broken legs, I had shattered the nerves that tell the muscles when to lift your feet up.” It was the end of Cliff’s racing career, but bearing in mind what had happened to Chris Bristow and Alan Stacey at Spa the year before, you can only conclude he was lucky. Certainly, snapper Malcolm Griffiths, Neil and myself feel privileged to be standing at Mallory 40 years on talking to this kindly-faced fellow in period overalls, Les Leston boots, original varnish-bonded canvas crash hat and goggles. Cliff, by contrast, isn’t in awe. Quite the opposite, in fact; he’s giving us a debrief on his half-hour reacquaintance with the 12.

“It was great fun. I never got the line of the long first corner right; I was changing down, until I realised I was better off leaving it in top and concentrating on the line. Once I’d got it right, I did feel it skipping on the exit.”

I get a flashback of the photograph Cliff had shown us the previous evening, of him tricycling the 12 around Spa on his way to fourth in 1958. It was a brilliant drive that could so easily have been rewarded with victory, since the three cars that beat him that day — the Vanwalls of winner Tony Brooks and third-placed Stuart Lewis-Evans and Mike Hawthorn’s Ferrari — would not have lasted another lap.

“But there wasn’t another lap, so that’s that. I didn’t regard it as a missed opportunity, really. To be honest, we were very pleased to have come fourth. For a spindly thing like a Lotus 12 to have done so well compared to the might of Ferrari, Vanwall, Maserati and so on — it was quite a good result, wasn’t it?” Neil drives the car regularly, and says the 1.5 Climax is plenty powerful enough for him, since the 12 can get pretty twitchy. Its pared-to-the-bone lightness does wonders for its turn-in, but its consequent skittishness could necessitate the brown corduroys. Neil has been impressed, therefore, by tales of a 12 being clocked at 178mph at Spa. He seeks confirmation. “Oh yes, that would have been me,” nods Cliff. “With a 2.2 engine, it was like riding on a bullet. Out of tight corners, especially, it was like a dragster.”

Chapman was one of Cliff’s biggest fans, their relationship cemented when the man from Westmorland joined the short list of drivers who have chalked up a top-six finish on their grand prix debut, in Monaco 1958. But who else on that list worked on the cars, as a mechanic, the night before the race?

Cliff finished sixth at Zandvoort, then scored Lotus’ first points (no cigar for sixth until 1960) with that brave Spa effort. He lined up fifth at the British GP, equalling the time of Mike Hawthorn’s Ferrari, and two weeks later at the ‘Ring, using the new 16 fitted with a 2-litre engine, he was again in with a shout of victory.

“I had had only one practice session in a brand-new car, but we clearly had potential. I loved the Nürburgring because it was made up of roads similar to those from my area, the Lake District. Also, I found I could memorise circuits easily, so was able to race quite well there. I was in third place, in touch with the leader [Tony Brooks’ Vanwall] on the last lap, when the radiator burst.” He had done enough to attract Enzo’s attention. Hawthorn had told Il Commendatore of his intention to retire at the end of ’58 — and recommended Cliff as his replacement.

Ferrari was convinced. Cliff remembers fondly his first year with the Scuderia. “It was a terrific team. Tony Brooks was lead driver, and was unlucky to miss the title that season. Phil Hill and I were only in our second seasons, and Dan Gurney was a rookie. Dan became a close friend,” he enthuses. Aside from startling everyone with the quickest time at Avus (the lap didn’t count as he was listed as a reserve driver) and a fifth at Monza, the season was a learning one for him, gaining experience, developing a rapport with his Italian mechanics.

The following year started on a very positive note, Cliff winning the Buenos Aires 1000kms in a Ferrari Testa Rossa shared with Phil Hill. It was in Argentina that matters F1 also started to look up. In the heat of Buenos Aires, his 246 Dino was second despite nimbler rear-engined Coopers showing the way forward.

Then, disaster. Cliff crashed in qualifying at Monaco. He was hurled from the cockpit and struck the straw bales, which were reinforced with telegraph poles and huge metal bollards. “I misjudged my altitude,” he chuckles. “Had I got it right, I could have emulated my idol, Alberto Ascari, and gone into the water.” An arm was so badly broken that his 1960 season was over. “There were three alternatives, as I saw it: to stay with Ferrari; to retire altogether; to get a Formula 1 drive somewhere else. I took the last option which, in retrospect, was probably the worst”

After the Spa shunt, and the consequent decision to retire, Cliff’s next visit to a GP was at Silverstone in 1963. “All my friends made a fuss of me, but seeing them racing when I couldn’t made me so miserable. I didn’t go again for about 20 years.

“One of the nice things I do remember from that weekend is going to see Colin Chapman, who said: ‘I only wish I could have given you a better car when you were racing for me’.” A typically blunt ‘Chunky’ assessment that perhaps sells the 12 a little short, but which speaks volumes for Mr Allison.

And Chapman said: Let it be light

The first purpose-built Lotus Single-seater was intended for the new 1500cc F2. The car had a spaceframe chassis with an aluminium floor hard-riveted to the bottom to increase rigidly. It housed a 1475cc Coventry-Climax FPF, producing 141bhp.

Packaging was typical Chapman, aimed at reducing frontal area and drag: the engine was canted downwards so the prop passed as low as possible under the seat to the rear wheels, facilitating a low driving position; the radiator was angled backwards to allow for a sleek sloping nose.

It featured a novel gearbox, designed jointly by Chapman, Richard Ansdale and Harry Mundy. A small, lightweight, five-speed sequential unit, some wag at Lotus christened it the ‘queerbox’. The first chassis had a de Dion rear axle, but on subsequent cars this was replaced by a ‘Chapman strut’ — an angled spring/damper assembly, a radius rod to take fore and aft loads and lateral location provided by the halfshafts. At the front, a lower wishbone plus upper link stabilised by the anti-roll bar located the Standard/Triumph Alford & Alder upright, while braking was provided by discs, outboard front, inboard rear.

The ‘Wobbly Web’ wheels were another innovation included in the interests of weightsaving. The whole package was wrapped in a cigar-shaped body, sketched by Chapman and produced by Williams & Pritchard.

After testing the prototype at Silverstone in March 1957, a new 12 made its debut at the Goodwood Easter Monday meeting with Cliff Allison at the wheel. It retired with a twisted rear halfshaft.

Results that season were peppered with retirements, usually caused by failures in the driveline and/or suspension. Mac Fraser and Allison’s second places at the Brands Whitsun meeting and Oulton Park Gold Cup were the best of the year.

After solving initial problems caused by poor lubrication, the queerbox was further enhanced towards the end of ’57 by a move to a positive-stop mechanism. Its designer, fresh out of university, was Keith Duckworth. For 1958, Team Lotus stepped up to Fl, using a stretched FPF of 1960cc, and a further evolution of 2207cc. The first appearance of a works Lotus in Formula 1 spec came in the BRDC International Trophy on May 3, Graham Hill finishing eighth in a 2-litre Lotus 12. A fortnight later, Hill and Allison made their GP debuts at Monaco. By the French GP, however, the team was focused on the 16.

Works and privateer 12s were raced in F2, Ivor Bueb scoring the only international wins for the model, the Crystal Palace Trophy and Helsinki’s Elaintarhanajo-Djurgaardsloppet, at the wheel of Motor Sport’s test car, 359.

The final works appearance of a 12 was in the Lavant Cup F2 race at Goodwood in March 1959, Hill netting fourth. Twelve chassis were built, the majority of which survive. Sadly, the first running prototype, 351, was destroyed by fire after being shipped to Australia late in 1957. Three cars (352, 353 and 359) are currently running and they should soon be joined by 357, Cliff Allison’s regular mount.
