1971
was a very significant year. From a
personal perspective, I started my automotive career-proper at BMW, while, much
more significantly, the BRM P160 proved highly competitive in Formula 1, LPs of
great quality were released, such as Sticky Fingers, Who’s Next
and Tapestry, there was the announcement of cars like the Alfasud,
Maserati Bora and BMW 2002 Tii, and . . . hope sprung of a new dawn in the
Cam-Am Challenge, with the addition to the grid of the Lola T260 and its
driver, Sir Jackie Stewart.

A
Lola T70 Mk.2 in the hands of John Surtees had won the inaugural Can-Am Challenge in ’66. However, since then, the
M8 McLaren in its various iterations had steam-rollered the opposition, firstly
as the Bruce and Denny Show (Bruce McLaren and Denny Hulme), then with
Peter Revson partnering Hulme after McLaren’s death in 1970. At the time, many of us resented the McLaren
‘win machine’ as the cause of the Group 7 series becoming boring because of
repetitive, predictable results.

One
of the very few series rivals to get anywhere near bothering the McLaren juggernaut
was the Chaparral team of the innovatory Texan, Jim Hall. Not content with seeking ultimate
competitiveness from high downforce aerodynamics by mounting a tall rear wing
on his 2E machine during the ’66 season, he surprised everyone four years later
with his 2J – a car that achieved even more powerful ground effects by
mechanically sucking air out from under its floor. This was facilitated by a pair of
rear-mounted fans and thus anticipated the similar solution devised by Gordon
Murray for the Formula 1 Brabham BT 46B of 1978. Not unexpected really, as his high wing
concept had also found its way into Grand Prix racing during the 1969 season. The 2J ran in only six Can-Am races in 1970,
driven in the second of these – Watkins Glen – by the reigning F1 World
Champion, Jackie Stewart. In that first
year of the new decade, Jackie was feeling the dispiriting effects of the deaths
of several fellow drivers accumulated over the later years of the 1960s, and,
ironically, persistent criticism of him about his safety campaigning. Unsurprisingly, his enthusiasm for his
profession was waning. However, the
revolutionary nature of the 2J was enough to revive his interest. In his autobiography, Winning is Not
Enough, he says: As we were discussing what to do about the Nurburgring,
(its dangerous aspects) I was called away to take a telephone call from
America. It was Jim Hall, inviting me to
drive the Chaparral in a sports car event, and, even in the middle of all that,
I found myself getting as excited about the prospect of being behind the wheel
of such a special car as I had at any stage of my life. I instantly accepted his offer because the
Chaparral was known as the most advanced racing car of its time. Although his race at Watkins Glen ended in a retirement,
the experience seems to have had a positive effect, for it was not too long
before it was revealed that Stewart had reached agreement with Carl Haas to
drive the new Lola 260T in a full 1971 Can-Am campaign. Jackie was frank in the autobiography: The
F1 season was my priority, but Cam-Am offered a second income stream that was
hard to resist.

Haas
was a classic mid-century American automotive entrepreneur. A Jewish immigrant to the ‘States just before
WW2, he ran cars in several race series, including NASCAR, F5000, F1 and
Indy/Champcar in addition to Can-Am, eventually becoming best known for his
association with Hollywood’s Paul Newman and the formation of Newman/Haas/Lanigan
Racing. In the late sixties he contracted
with Eric Broadley to act as the U.S. importer of Lola racing cars and
developed the business to a highly successful level. Broadley was happy to allow Haas to function
as a works team and the American used his commercial nous to secure supportive
sponsorship from cigarette makers, L & M.
Whilst Lolas had been a familiar part of the Can-Am scene in the late
sixties, they had been relatively conventional and not front-of-the-grid
competitive. With such characteristics
persisting in the new decade’s opening season’s Lolas – the T220 and T222 – Haas
used all his powers of persuasion to convince Broadly that a more daring new
design was essential if the perception of the Lola brand was not to be devalued
because of lack-lustre results.

Broadley
acceded to Haas’s entreaties and briefed his designer, Bob Marston. He also sought input regarding bodywork from
his associate, Peter Jackson, (and body engineer Peter Wright), at the expert glass
fibre fabrication firm, Specialised Mouldings. Broadley wanted a basically wedge shaped,
compact form, with a relatively small overall footprint – he was keen for
instance to avoid the substantial front end overhang seen on the McLarens. But since the wedge format could, as had been
seen with the Autocoast Ti-22 at Mont Tremblant in 1970, be prone to end-over-end
loss of control incidents, the main aerodynamic emphasis was on the avoidance
of front end lift, coupled with maximum possible downforce on the rear
axle. The latter was sought without any
particular focus on the rear body surfaces but by simply using a large wing –
not especially high mounted, but full width and located unusually far forward, most
of its surface in front of the rear axle.
An additional distinctive bodywork feature was the presence of 207 small
holes in the upper surface between the windscreen base and the front brake air
duct openings. These were for the
purpose of releasing air that otherwise would cause a build-up of high pressure,
and thus lift, underneath the front end of the monocoque floor. The nose incorporated a depth-variable front
splitter.
Otherwise,
the T260 was largely ‘state of the art’ for the time, featuring an aluminium
monocoque, side mounted radiators, horizontal mounted, rocker arm actuated front
springs and inboard brake discs, front and rear. A relative novelty was the specification of 13”
front wheels. The engine was a Foltz-built 8.1 litre big block Chevrolet V8
mated to a Hewland Mk.2 four speed transmission. Output at 7,000 rpm was commonly quoted as
being 700-760 bhp and 600+ lb-ft torque.
Foltz offered some options regarding the amount and spread of torque
generated in order to make easier the evaluation of the car’s handling during
the early stages of development.
At
the time, Frank Gardner – mostly known for his F5000 and saloon car exploits – was
Lola’s test and development driver. He was
able to take the T260 out on track, (at Silverstone), for the first time in May
1971. With the first round of the Can-Am
due at Mosport in Canada in mid-June, scope was limited. Gardner was quick to express his concern
about this because it was immediately apparent that the car inherently
understeered, and a ‘cure’ would likely require a considerable number of
testing miles.

Stewart
for his part encountered the car at Silverstone at the beginning of June. The weather was against him – heavy rain – and
his initial impressions are not recorded.
He had however already prevailed upon Broadley to make a significant
change. Ten months previously Jochen
Rindt’s accident at Monza in the Lotus 72 still weighed heavily on the World
Champion’s mind. Not only were the
Stewart and Rindt families very good friends, but Jackie was especially close
to Jochen, considering the Austrian his principal rival on-track. Though the sudden, violent sharp left hand
swerve into the Parabolica armco was not per se the cause of Rindt’s death – that
was attributable to his belts not being properly secured – Stewart was highly
sceptical about the advisability of running inboard front brakes, given the
possible consequences of a shaft failure.
Broadley had no alternative but to agree that the front brake discs be
moved outboard. At the same time, a
similar revision was effected at the rear, since the limited testing so far
completed had revealed problems with heat not being dissipated sufficiently
from the discs. And there was a knock-on
from this. To accommodate the relocated
discs, larger diameter – 15” - front wheel rims were required – along with an
enlargement of the leading curve of the wheel arch.

We
do know that Stewart at last had the chance to drive the T260 in unconstrained
circumstances at the Mosport circuit on 10th June. His perception of the car’s handling
characteristics – not helped by the bumpy nature of the track – were summed up
by his apparent likening of the machine to a ‘pregnant elephant!’ The following day he was nevertheless able to
set the day’s fastest time and this proved to be good enough for pole position
when the Saturday session became rain affected.
Next day, at the opening round of the Can-Am season, he led the race
from Hulme’s M8F, but retired just short of quarter distance because of a
failed transmission seal. The McLaren
team had had a scare, but Hulme took the victory and the marque’s cars filled
places 1-6 in the race results table.

Two
weeks later, Round 2 of the Can-Am series was scheduled for Mont Tremblant. Like Mosport, this was circuit notorious for
its uneven track surface. Stewart
however was hoping for a better ride from the T260 as some additional changes
had been made after the Mosport event.
The rear suspension geometry had been revised and the wing relocated a little
further to the rear of the car. But in
practice and qualifying the car still proved to be hard work. Stewart nevertheless managed to qualify the
T260 2nd, just three tenths slower than Hulme’s pole time and 1.8
seconds better than Peter Revson’s 3rd place time in the second M8F. Though Hulme maintained a lead for much of
the race, he didn’t really get away from the Lola and when he flagged in the
latter stages, Stewart was able to get past and take his car through to its
maiden victory.

Road
Atlanta
hosted Round 3 in mid-July. Stewart
qualified 3rd, a full second off Hulme’s pole time. The race was a mixed bag for the Lola – Stewart
hustled it enough to record the race’s fastest lap, and moved up past Hulme and
Revson into the lead. However, the T260
then suffered a rear tyre puncture and the pit stop to fix this became
prolonged when the engine cut and didn’t want to restart. Although running at the finish, the car was
several laps down having also developed a rear damper failure – a disappointing
outcome as it had clearly had the beating of the McLarens on track.

A
fortnight on, the Can-Am circus reconvened at Watkins Glen. Perhaps helped by his familiarity with the
Glen from his Grand Prix drives there, (as was the case too at Mosport, and, to
a lesser extent, Mont Tremblant), Stewart put on another strong qualifying
show, just pipping Revson and Hulme to the pole. Next day he held a comfortable lead until a
little past the halfway point, when a driveshaft failure intervened and forced
retirement of the car.

Round
5 must have felt like ‘back to square one’ – the Mid Ohio circuit, like
the opening, Canadian, rounds’ venues was something of a car breaker, being
notable bumpy. In qualifying the
McLarens handled this better than the Lola – Hulme’s pole time was nearly a
second quicker than Stewart’s 3rd place lap. But it was fortunate that the T260 was not
further down the grid as it had been afflicted with multiple suspension
failures during practice. The confidence
evident in Stewart’s demeanour at the Glen was also undermined by his
perception of Mid Ohio as a particularly dangerous track with limited run-off
areas and a host of trackside hazards. He
was forthright on Sunday morning in saying how dissatisfied he was with the
place and that he didn’t intend to run at anything like his or the car’s full
performance potential. Thus it seemed
somewhat paradoxical that following the demise of both the M8Fs with driveshaft
failures, Stewart was able to chalk up his second victory of the season.

In
late August the second half of the series opened with the 6th Round
at Road America, (Elkhart Lake). With
the Mid Ohio win serving to re-boost confidence and signs that the long-established
McLaren superiority might be faltering with reliability issues, there was good
reason to expect that Stewart would be hunting Hulme and Revson down for the points
table lead. As an added positive, the
Haas team was also keen to be more adventurous in its efforts to improve the
car’s handling and aerodynamic behaviour – the chronic understeer still being a
real issue for Stewart. Thus, the car
appeared at the Wisconsin circuit with a fully reworked rear end – an even
larger-surface (and higher incidence) rear wing, with substantial end plates
integrated with the rear quarter panel sides.

edge of the nose.

Practice
and qualifying threw up some surprises. Whilst
Hulme secured the pole with a time 2 seconds quicker than his nearest
challenger, that competitor wasn’t teammate Revson – or even Stewart. Finally coming good was the controversial
Shadow Mk.2 of Jackie Oliver. Stewart
was 3rd, but apparently hampered by a lack of power. The team bit the bullet and changed the
engine for the race, but this overheated and failed after just 10 laps. So it was an unsatisfying end to the weekend
with uncertainties remaining, especially in regard to the car’s aerodynamics,
the original rear wing form having been reinstated and no conclusions reached
about the persistent understeer. Broadley
was struggling to understand cause and effect, though he had demonstrated his perspicacity
in wondering how well the body surface holes were relieving under-floor
pressure when the gauze covering of many of them was clogged with paint
required for the L & M livery! One could
not help but wonder if the car was founded on an aerodynamic theory full of
holes.
With five Grand Prix wins
up to August 1st, Stewart was assured of his second World Championship
by the time of Round 7 of the Can-Am at Donnybrooke. He was no doubt philosophic about the
contrast between his successes and confidence in his Tyrrell and his results
with the Lola, to say nothing of how little he’d been enjoying driving the
Group 7 car. The team would have hoped
to have had him smiling a little more by effecting some rear suspension upgrades
following the Road America event. But
hope was outdone by reality in this instance – the McLarens seemed to be
getting better after the mid-season frailties, whereas the Lola’s handling
continued to tax Stewart’s patience. With
no improvement clearly obvious from the revisions tried at Road America, the
rear wing form reverted to the original format.
As was becoming the pattern, Stewart was 3rd in qualifying, not
especially close to the times of Hulme and Revson. Nonetheless, the Lola got off the line well
and headed the M8Fs initially until Revson went past for the lead. Stewart was able to hold Hulme behind him, but
various troubles led to pit stops that hampered Stewart’s progress to the
extent that he could finish no better than 6th.

Late
September saw the Can-Am back in Canada, at Edmonton for Round 8. There was a further revised, tacked-on
‘shovel’ panel in place to give the nose
a more scoop-like profile and almost all of the rear wing depth was now behind
the back edge of the rear panel. The
effectiveness of these changes was difficult to judge in the track conditions
and Stewart’s qualifying performance could once again not achieve anything
better than 3rd. In the race,
his ultra-smooth skills enabled him to take and maintain the lead on a wet
circuit. Eventually, however, he had an
off, and this apparently caused some damage, as the T260’s handling was
subsequently less manageable. It
nevertheless remained one of the car’s better days, as Stewart was able to run
to the finish headed only by Hulme’s McLaren.

Laguna
Seca was the location for the
penultimate round. Despite Stewart’s big
and unsalvageable points deficit vis-a-vis the McLarens, effort was ongoing to
try and give him a car which could match his other-worldly driving
expertise. This time there was some
astonishment when it was seen that the front of the car was no longer just
being augmented with a relatively small re-profiler – it now had a substantial
tubular structure projecting forward of the nose, supporting a large,
full-width aerofoil which was promptly nicknamed, ‘The Cowcatcher.’ The rear wing remained distinctly rearward of
the back panel and run at a steeper angle of attack than as seen at Edmonton. The T260 had begun the season as the ultimate
‘stubbie’ but now boasted an exceptionally long footprint.

In
qualifying, Stewart was within a second of Revson and Hulme, the former taking
pole. However, the Lola was 4th
on the grid as the Mk.2 Autocoast Ti22 was three tenths quicker in the hands of
David Hobbs. The Ti had less race pace
and was soon displaced on the Sunday by Stewart who further progressed by
passing Hulme for 2nd. Revson
struggled with an ailing engine to finish the race but hung on to take the win. There was some post-race confusion as it was
contended by the Haas team that Revson should have been black flagged and the
race awarded to the Lola. However,
Revson’s victory was subsequently upheld, so Stewart had to be content with 2nd
– itself by no means a bad result.

The
teams were at Riverside at the end of October to close out the Cam-Am
series. The T260 made its way to its
customary 3rd fastest in qualifying.

place until the engine failed with 3/5 of the race run.

On
face value, the final series points table for the top three suggested ‘business
as usual’ for McLaren. However, Stewart
and the T260 had provided the most substantial challenge for a very long time
to the dominance of the M8s.
Although
there was never any prospect of Stewart committing to another season with Haas,
it’s reasonable to suppose that with a winter of development and a new,
ambitious driver, the wins tally could have been considerably greater than just
two in 1972. However, the obdurate
handling problems of the T260 had taken their toll. For Lola, the attraction of a new start
became irresistible, and thus Broadley laid down a brief for the T310 – a
Can-Am car that was long and wide and looking not at all related to its short
and stubby, highly characterful, predecessor.
But I have to leave the last word to Sir Jackie: I enjoyed working
with Carl Haas in 1971, but the car had been a dog to drive . . .
