Jaguar's Le Mans comeback: How Big Cat conquered 24hr race again

Le Mans News

Jaguar leapt into the Group C bear pit in the 1980s, looking to revive its 1950s Le Mans 24 Hours successes. Andrew Frankel explores how it did just that, vanquishing Porsche with its now-legendary Silk Cut XJRs

I was there, legs hanging over the old pits, when the Jaguar XJR-9LM of Andy Wallace, Jan Lammers and Johnnie Dumfries won Le Mans in 1988. I can remember the almost physical release of pressure in the crowd when Jan brought the car over the line to end Porsche’s run of seven straight wins in France. And we didn’t think too much about how the Jaguars really should have won the year before, nor did we know by how thin a thread – a single shaft holding its gearbox together – even that ’88 win had hung. And we certainly didn’t think about how Jaguar got back to Le Mans in the first place after all those years away. For that is a story which starts not in France, nor even in England, but in a land far, far away.

Would Jaguar have won at Le Mans in 1988 had the American race car driver Bob Tullius not found himself eight years earlier short of work for his race team? It is one of those questions that is as interesting as it is unanswerable. It is possible that Tom Walkinshaw, fresh from eventual success with the XJ-S in the European Touring Car Championship would have put together a proposal that resulted in a Jaguar Group C car anyway, even if Tullius’ Group 44 operation had not already built a prototype of its own and had been using it with considerable success in the cross-pond IMSA category racing for which it was designed.

“The XJR-5 was good, but we were up against the most successful sports car ever built”

Nor should we allow ourselves to think of what Tullius was up to a private affair with no connection to Jaguar or the factory. Because it happened over there, it is tempting to think the company itself had little involvement in the project. On the contrary: the pitch to Jaguar was made by none other than Mike Dale, then the marketing boss of Jaguar in North America and signed off in 1981 by the newly minted chairman of a Jaguar finally free from the clutches of Leyland. Group 44 was to Jaguar in the early to mid-1980s very much what TWR became thereafter.

Tullius’ IMSA car, which Dale christened the XJR-5, was as fluently executed as you’d expect a Group 44 product to be, but very conventional. An aluminium monocoque carried a 6-litre version of Jaguar’s already ageing V12 motor as a fully stressed member producing initially around 570bhp and designing not only with IMSA regulations in mind, but those that would permit it to race at Le Mans. It was quite successful too, winning several races despite an inbuilt disadvantage relative to the turbocharged Porsche 935 and March-Porsche 83G.

But at Le Mans in 1984 against the fully developed Porsche 956 it stood no chance despite a driver line up including Brian Redman in one car and John Watson in the other. In qualifying the quicker of the two was still 17 sec off the pace of the pole-sitting Lancia LC2. “Sadly, we just couldn’t get near the Porsche,” Redman told me. “The XJR-5 was a good car, but we were up against the most successful sports racing car ever built.”

“The Group 44 team were very impressive,” he continued, “the cars were the best turned out on the grid and immaculately prepared but really taking on a car designed by Porsche and to do so with a normally aspirated road car engine was never going to be an equal fight.”

The two cars were back in 1985, now over 20sec from pole and while one car driven by Tullius himself sharing with Chip Robinson did complete the race, it came home in 13th place, 50 laps down and minus one of its twelve cylinders. Winning the GTP category came as scant consolation given that the Jaguars were the only cars entered therein…

Besides by then Tullius knew the adventures at Le Mans with Jaguar were over. Jaguar had decided to continue the campaign, but contracted the work out to TWR instead. If Tullius was bitter he did a fine job of disguising it. “While I was disappointed that TWR was given the job, I wasn’t surprised,” he said. “I guess it would have been a little odd for an American team to do a works Le Mans programme for a British manufacturer.” He instead developed the XJR-5 into the composite chassis XJR-7 which raced in IMSA with some success for another couple of years.

And Tullius did what he could to help Walkinshaw, lending three XJR-5 chassis to TWR as they sought to perfect their own, very different, Tony Southgate-designed XJR-6. There was a plan to run the car with 48-valve heads too, which were designed, tested and gave enormous power but were abandoned either because they could not get the fuel consumption to sit with the Group C regs, or because it added more weight high up to an already high and heavy engine. Probably both.

“You can see why Jaguar chose Walkinshaw for the Group C car,” says Redman who raced not only a Group 44 XJR-5 at Le Mans in 1985 but also a TWR XJR-6 in 1986. ‘Tom’s car felt like it was from a different generation. It had a carbon-fibre tub, more power, better brakes and far superior downforce. It was lighter, quicker, stiffer, better in every way you could measure.’

It’s perhaps not widely appreciated today that the original plan was for the TWR and Group 44 Jaguars to race at Le Mans together in 1985 and if you look at the entry for that race you will indeed find no fewer than three XJR-6s on the list. It’s a shame the cars weren’t ready because the comparison would have been fascinating, even if only to see how much faster the British car would likely have been. With the engine expanded to 6.5-litres and its output up to 650bhp, with proper venturi tunnels for full ground effect and its state of the art construction, it made the XJR-5 look exactly what it was: a well engineered but quite conservative race car from another era.

The TWR Jaguars instead made their debut two months later at Mosport with one car driven by Martin Brundle, Jean-Louis Schlesser and Mike Thackwell winding up not only on the podium but best of the rest behind a brace of factory Rothmans Porsche 962s. It was a very encouraging start, followed by splitting the two Porsches at the season finale in Malaysia. But the first win didn’t come until Silverstone the following year when Derek Warwick and Eddie Cheever beat the factory Porsches and Lancias in what was, astonishingly, the first victory in the World Sports Car Championship by a factory Jaguar since that dreadful day at Le Mans in 1955, some 31 years previously.

But Le Mans was too high a hurdle in the first full year of the TWR programme. We should not pay too much attention to qualifying times in which Porsche could use boost levels unavailable to them in the race, but the fact is the Jags were never really in the hunt. Then fuel pump failure stranded one car, half shaft failure another. It is true that the third, driven by Warwick, Cheever and Schlesser, was in second place on Sunday morning when a blown tyre destroyed both its suspension and chances of finishing the race, but so too was it eight laps down on the leading Porsche at the time. No more wins came that season, leaving TWR with a lot of work to do over the winter.

The team did not waste its time. The XJR-8 that made its debut the following season was arguably the most successful racing car ever to wear a Jaguar. Now revised in all key areas and boasting a 7-litre engine in a ten round season, it won eight times, missing out only on the sprint race at the Mickey Mouse Norisring and the race for which it would have sacrificed all others: Le Mans. Jaguar was World Champion by miles but the ultimate prize still eluded the team.

What’s more, a disagreement between Porsche’s engine management and the ACO-supplied fuel knocked out one of the two works 962Cs, leaving the survivor to face three XJR-8s. It led into the night, chased by a pack of howling Jaguars, but one by one they faltered, leaving a sole survivor to finish fifth behind four Porsche-powered cars.

So the following year TWR threw the kitchen sink at the race, with no fewer than five XJR-9LMs entered but the team was as fortunate in 1988 as some much argue it had been unlucky in 1987. For now it had a new opponent in the form of the works Sauber-Mercedes C9s which had hounded the Jaguar through the season to date. But then Klaus Niedzwiedz performed the biggest save of his life when a tyre let go at something around 230mph in the Mulsanne kink leading Mercedes to withdraw both its cars when the problem could not be identified. After the tragedy of its previous works effort at Le Mans in 1955, such caution was understood.

The rival instead was a very special Porsche 962C, built especially for this race and driven by Porsche’s best drivers, Hans Stuck, Derek Bell and Klaus Ludwig. Would it have won had Ludwig not run it out of fuel? Who knows but the gap at the flag was certainly far less than the time that had been lost. Remember too it was the only one of the five Jaguars to remain in contention, two retiring, the other two respectively 11 and 63 laps behind the winner.

But Mercedes was back in 1989 and, as if to prove a point, won every single round of the championship, scoring over three times as many points as the now outclassed TWR Jaguars. And even though Le Mans was not part of that championship thanks to one of those spats between the ACO and FIA that pop up from time to time, it made very little difference: the Mercedes simply ran away with it, finishing first and second with the best of the four works Jaguars down in fourth, beaten even by an old privateer Joest Porsche. Something needed to be done.

And the XJR-12LM was it. Throughout the 1990 season the Mercedes C11 was the class of the field, even against the new twin turbo XJR-11 it met at sprint events. But for Le Mans TWR deemed the old V12 to offer a better chance of victory even on a circuit with a straight now punctuated by chicanes. Victory seemed even less likely that the previous year however, not just because of the Mercedes menace, but no fewer than eight Nissans, including six works cars, one of which Mark Blundell used for one of the most ridiculous pole laps it has ever been my pleasure to watch on YouTube. The fastest of four Jaguars languished down in seventh place behind a gaggle of Nissans and private Porsches, fully nine seconds off its pace. Rumours were that Nissan had already printed its victory literature. But the Mercedes never turned up, the PR reason being it didn’t want to take part having won the previous year and while the race retained non-championship status. Privately people wondered if it hadn’t already decided it didn’t much fancy losing to a Nissan.

It is a decision the team must have come to bitterly regret. Nissan’s apparent vice like grip on the race fell to pieces in an orgy of unreliability leaving what should have been a straight run to the flag for the Jaguars. But even now they were hard pressed by the brilliantly driven and run Brun Porsche 962 which lay within striking distance of a Jaguar carefully managing its gearbox with just an hour to go. Walkinshaw was sufficiently concerned to parachute Brundle from a broken sister car into the leader for the final stint but in the event he need not have bothered: with three laps to go the engine of the heroically driven Porsche let go, leaving its driver Jesus Pareja literally weeping at the side of the track.

The 1991 running of the Le Mans 24 Hours was surely the weirdest in its history. It was a race in which some of the cars that took part weren’t meant to be there and others that were meant to be there didn’t take part. It was a race where the car on pole was over three seconds a lap slower than the car starting down in 11th place, which itself was almost 40 seconds a lap (yes, 40) faster than the car immediately ahead of it on the grid. It was a race that attracted the smallest entry in almost 60 years and was won by a car of a kind that had never won before, nor has since, and that would not come close to even troubling the podium in any other round of the 1991 championship season.

Very briefly, the only way Le Mans was getting back into the championship was to subscribe to the new Group C rules that mandated 3.5-litre engines. But there weren’t enough of them, so the old cars were allowed to race for one more season, albeit ballasted to, in theory, make them uncompetitive. Mercedes and Jaguar both had their new 3.5-litre cars and brought them to Le Mans with zero intention of racing them knowing their chances of survival was almost nil. But the ballasting didn’t slow the old cars by as much as expected, and Jean-Louis Schlesser’s pole time in the old C11 was 3.5sec faster than that of the 3.5-litre cars. So the ACO said the highest any old Group C car could start was 11th. The only exception was the rotary-engined Mazda team, which because it was technically an IMSA rather than a Group C car, avoided the ballast penalty, running fully 170kg lighter than all the other Group C cars. And the fact that six times Le Mans winner and double sports car World Champion Jacky Ickx was their manager surely had nothing to do with it.

At the start the Jaguar and Mercedes teams simply let the 3.5-litre cars go – a pair of Peugeot 905s being the only serious players in the category – in the almost certain knowledge they’d break, which they duly did. The Mercedes had the legs of the Jaguar as it had the year before, but the unencumbered, bulletproof Mazda was a constant concern for both teams. Uncharacteristically it was the Mercedes team that proved vulnerable, its best car retiring with a three lap lead with just three hours to go, gifting the best Mazda a lead it would never lose, despite the best efforts of the hard-charging but overweight Jaguars. At the flag Ickx’s team won by two laps, followed by three XJR-12LMs on the trot.

Most people think that’s the last time a Jaguar raced at Le Mans, but it’s not. Then again perhaps the less said about the Gentilozzi-entered XKR which qualified last in 2010 and expired after just four laps, the better.
