The Car That Took Down Porsche

Through its early years Group C Sportscar racing was dominated by just 1 manufacturer. Porsche. With the 956 and 962 Porsche defined the era, winning Le Mans 6 times in a row. But by the late 80s a new challenger was emerging. Swiping Porsche’s long held World Sportscar Championship crown in 1987, then ending their Le Mans winning streak too in 1988, Jaguar put an end to Porsche’s dominance, and it was no fluke.

Like you tried telling 5 years old me that brand is cig and I wouldn’t believe it. The colors of red and white along with the arrow shape just makes it a really striking but simple design next to gulf and martini.

I am a lucky man went to every LeMans from 87 to 91 and 95 for the XJ220 also every Silverstone, Brands Hatch & Donnington 1000km oh & a Spa race, during this period. Don’t know if I missed this point & I know it isn’t part of your subject but every year Jaguar won LeMans they also won the Daytona 24 hrs a few months before. Some people have commented that the Jag engine was the worst in group C. The whole point was jaguar cars wanted their cars to race with an engine that actually came out of their road cars! It worked I owned a BRG V12 XJS for years. Oh at Brands Hatch they raced one car with a 48 valve engine (normally the V12 is only 24 valve) they found out it was far to top heavy and went with the V6 turbo engine.

Good stuff! I watched the Jaguars throughout the IMSA GTP days race at Mid-Ohio. The GTP days were magical watching all the manufacturers beating the hell out of each other each week. Mid-Ohio was packed to the hilt for the IMSA GT weekends with SCCA Trans-Am series racing too. It was a race fans dream weekend actually. Trans-Am back then was also a manufacturers battlefield. I see those battlefields starting back up next year with GT/Hypercar/Prototype again....can't wait! Multiple manufacturers racing each other is the best.

Great content. One correction though... the XJR-16 was developed by TWR USA for use specifically in IMSA GTP. The design ethos was maximum downforce, at the expense of aerodynamic efficiency. TWR considered this most appropriate for the IMSA GTP tracks of the time... mostly street circuits and high downforce tracks like Laguna Seca and Lime Rock. The high downforce, high drag design would have been ineffective on the smooth, longer circuits of Europe. The keen eyed among you will point out that the XJR-16 won at Road Atlanta and Road America in 1991 - both tracks that emphasize straight line speed (especially Road America). I have no response for this...

[@exhorderhd]

Very good video explaining some of the lesser well-known characteristics of the Jag Group C cars. Thanks for that! I might add a couple of observations, happy to discuss those of course! First off, increasing engine displacement for the XJR-8 was less because of more top-end power, but for increased torque across a wider rev spectrum. This had a similar effect to what Mercedes were doing with their low-boost V8s. This lowered average fuel consumption, which was so critical in Group C. You can also observe the massive advances in carbon fiber technology during the mid-80s. Porsche actually looked at a CF chassis when designing the 956, but decided against it because they didn’t see a lot of advantages at that stage. Just a couple of years later though, it was evident that the conventional aluminum chassis couldn’t stand a chance against the newly designed Jag chassis - not just because of its lower weight, but because it could handle the increased load of that massive downforce you mentioned. And let’s not forget one crucial piece of the puzzle here. Yes, Tony Southgate‘s design was excellent in terms of chassis strength and aerodynamic refinement. Arguably though, Tom Walkinshaw‘s uncanny ability to bend the rules right up to the breaking point, and doing naughty things when nobody was looking, was even more important for TWR‘s success.

[@AfroMyrdal]

Hey man, your WSC/WEC videos are fantastic! The other videos are awesome too, but I really really enjoy these! I dread the day you've done them all and we won't have any more of them 😅 but I think there was a mistake in this one, @16:04 isn't that Sauber a V8? At least I always thought it was!

[@automobilistic]

all the Sauber Mercedes cars up to the C11 were V8s. But the 1991 C291 used a 3.5L N/A Flat 12 (which wasn't very good). Mercedes designed the new engine for the 3.5L N/A engine rule change that made their twin-turbo 5L V8 ineligible for group C1.

[@ziggystardust4627]

That Porsche achieved success in their first year in GrpC, whereas TWR took 3 years to get the championship, and 4 to get Le Mans, is an indicator of 2 things: 1. Porsche did really well out of the box 2. The bar to succeed in GrpC after Porsche got there was far higher than in the beginning. Once they got it together, they were fantastic, but then Sauber caught up and surpassed them. They did fundamentally elevate the level of the game, though.

[@marks7197]

Tom Walkinshaw always stated that three years was the target for Le Mans success, which they achieved in 88. It was 3 years not 4 as you stated because the XJR6 didn't run at Le Mans in 1985. As for Porsche winning in group c from the outset, somebody had to and the Rondeau, WM, SHS and Lola were not as competitive in the years before so no reason to suggest they would suddenly come good. The closest cars to the works Porsche initially were modified coupe 936's from the late 70's which tells you plenty.

Jaguar cheated to win the 1988 Le Mans. During the night, they brought in the lead car into the pits of one of the other 5 that dropped out, got that one extra tank of fuel to keep ahead of the 962C #17 which was relentlessly reeling it in lap-after-lap (especially during the rain, like 3-7 seconds a lap). I worked with the same mechanic I met at the race (I did an engineering stint for Porsche North America) from Jaguar. 1 year later he's at Jim Busby's IMSA team(Laguna Beach CA) who campaigned 962's in the US. He confirmed what was suspected all along (and I wonder WHY he looked so glum after the race at the celebration party...he KNEW that 'win' was as fake as a 3-dollar bill)). Today, with camera's/eyes everywhere, that wouldn't happen. - In hindsight, like the F40, whereas Jaguar debuted the XJ220 as a failed response to the 959(of which every car on the planet now has some it's DNA), the XJ220(which REALLY sucked) is but now a forgotten asterisk in history.

[@Kneedragon1962]

About 8 minutes in ~ I have one real question about this car. The engine was a large naturally aspirated V12. It was derived from the V12 in the road-going Jag cars of that era. Fine. Now, I am an aviation and flying nerd, have been for well over 50 years. I don't know about today, so much, but from the mid '70s through about 2000, we heard a constant stream of horror stories about people building home-built planes in the garage, which were 2/3 scale replicas of Spitfires and Hurricanes, and sometime something else like a Mustang, but usually Spitfires. Word at the time, born out by a tragically large data set, was that if you decided to give up the V12 sound and the 'pure British tradition & heritage' and made your plane with a Chev V8, that was more or less acceptable, and with a little bit of work, it could have the cooling system upgraded to be more than acceptable. We got the Aluminium LS motors and they were great. But ~ tragic part, if you used a V12 Jag motor, didn't matter what you did with it or how you modified it, the cooling system simply wasn't up to being used as an aircraft engine. They would & could & did overheat and stop, often violently. They killed people, dozens of people, over a 30 year period. Now my question, right in the middle of this period, Jaguar went racing in Group-C and won a world championship, and won Le Mans. So ~ the engine in the Le Mans Jag can't be the same engine that doesn't work in home-built aircraft, right? Well ~ as far as I can work out, it is. So [head scratch] WTF??? How come that engine is completely acceptable in a 24 hour endurance racing car, but complete amateur hour in a home-built plane?

[@luislongoria6621]

Do you know how a radial piston engine works? A rotary engine functions on the same principle yet those were only used on torpedoes

[@Kneedragon1962]

@@luislongoria6621~ Incorrect. They were used in torps, but they were also used on early aero engines. A radial engine has a stationary engine and the propeller bolted to the crank. A rotary engine has the crank bolted to the aeroplane and the propeller bolted to the engine casings. That's not the way we do it today but up until the end off WW1 in late 1918, that was the more conventional design. The reason had to do with cooling, and getting air-flow to every cylinder the same. Early designs found some pots never got up to full temp and others overheated, but if they spun the engine, that problem disappeared. Then you get things like the Wankel Rotary, which is a whole different animal again.

Hi

[@carlosmagnus717]

Very easy, with a 7-liter naturally aspirated V12 engine (760 HP), against a 2.65-liter biturbo (956) (620HP) or a 2.86 l. also biturbo (962) (680 HP), it's obvious that the difference in power is noticeable on the track. Then the Mercedes C9 and C11 would arrive with a 5.0-liter biturbo V8 (street car Mercedes E-500 engine) that exceeded 800 HP and that achieved 407 km/h in Les Hunadieres, that it would be the fastest and most powerful. From then on the regulations would put an end to turbo engines and only naturally aspirated engines were allowed, generally coming from Formula 1 with 3.5 liters of displacement limit such as the Jaguar XJR 14 (with a Ford HB engine like the Benetton F1 of the time) and the Mercedes C291 with a 3.5 liter V12 that wasn't competitive at all. Peugeot 905 would also debut at that time with Jean Todt's team, which had left rallies and debuted a naturally aspirated V10 that would later compete in F1 without much success, but only as an engine builder. At that time Jean Todt asked to join the lion constructor as a team in Formula 1 (chassis and engine) to which Peugeot refused, ending up Jean Todt to sign for Ferrari at the time of Michael Schumacher, Ross Brawn and Rory Byrne in Ferrari's succesfulest era in F1.

The horsepower of the cars was never particularly different in period, mostly due to having to stay within the fuel allocation. The turbo cars had a big advantage being able to turn up the wick as it were where fuel allowed them to. The Jags had to remain conservative in how they ran throughout.

@@marks7197 It's clear that the limits of fuel consumption tended to equalize performance, but the difference in displacements between Porsche and Jaguar first and Jaguar and Sauber-Mercedes (and Mercedes) later, was a fairly large distance even with fuel limits, since not only It was absolute power, it was also the torque values in the low and medium rpm range that compensated for those fuel limits. Then with the naturally aspirated engines things became quite equal, even the Mercedes no longer had that advantage, Jaguar with the Ford HB F1 engine didn't go much further either, and it was Peugeot with a new team, much more motivated and with an engine V10 that was designed to make the jump to F1 which ended up being the most competitive. Mercedes left Group C to also make the jump to F1 but already with an different engine that it bought from Mario Illien (Ilmor V10 engine) and that it would develop for many years until it became competitive but nothing to do with the flat 12 cylinder of the C291 which Mercedes itself designed.
