superfastlive4speed, you are totally right. Motorsports in general is awesome, but this forum is especially about a certain niche in motorsports, the Group C race cars. And, to add about what you said about the 787B, it was the only Japanese car to win Le Mans. Also, it was the only rotary to win Le Mans.
Layla's KeeperFor chrissakes, THE ROTARY ENGINE WAS NEVER BANNED AT LE MANS!!!!!!!!!!!!
How many times do I have to drag up pictures of Kudzus, Courages, and other WSC cars that used rotaries? I mean, seriously folks. What happened was a change in class format that rendered the Wankel uncompetitive due to restructuring.
And in fact the 787B compared to the other Group C cars of the time (especially the TWR Jaguars and Sauber Mercedes) was dog slow - slower than the Aston Martin AMR1 - and it was fuel efficiency and reliability in a freak year that landed Mazda the win.
Mazda knew that the N/A four row was down on power, and experimented with a turbo rotary GTP/Group C car in IMSA competition. It was fast but fragile, and gained a reputation in IMSA for setting itself on fire. However, the Crawford (yes, the Daytona Prototype chassis constructor Crawford) chassis was excellent and Mazda Motorsport was sure they could get the wrinkles ironed out.
Unfortunately for them, Cat. 1 came down heavy on turbochargers, favoring (as the ACO often does) the French Peugeot team. And so, in desperation to continue their winning ways, Mazda put their name on a TWR Cat 1 chassis with a Judd V10 engine. A 4th place finish was the reward for their trouble.
The Mazdaspeed boys took the next three years off and came back in 1995 with a Kudzu chassis WSC car. They nailed down 7th overall, which was not bad for going from custom 5.2L 4 row rotaries to a 3.0L 4 row version of the venerable 13B.
In 1996 Mazda re-motored again, going to the 20B three row and a different Kudzu chassis, going after the new LMP2 category, which they won although the result was a 25th overall finish amidst the remaining WSC cars, the abundance of GT1's, and the new LMP1's.
1997 the rotary presence was reduced to a privateer LMP1 Kudzu effort, but that team still brought the car home 17th overall.
This has been the pattern since then. Privateer entries, variations on the 13B, and Kudzu chassis. Now, though Mazda has funded an ALMS Courage/Renesis combination which scored an LMP2 class win at Mid-Ohio. The rotary has never left Le Mans. It has been restricted, bumped up in class, and lost support from a financially strapped Mazda racing budget, but certainly was never banned from Le Mans.
Layla's KeeperWell, bimmer, let's not forget that the rules changes were put in place to slow the turbo cars and to favor French manufacturer Peugeot's return to Le Mans.
Layla's KeeperThe Porsche 956/962 also had very little competition at Le Mans during the years it was winning. In the earliest years, the only "serious" competition that the 956 had was the Rondeau.
It wasn't until 1983 that the fast but fragile Lancia LC2's showed up. They remained the only threat to Porsche dominance of Group C racing until they withdrew in 1985.
Layla's Keeper1986 was the year that Tom Walkinshaw Racing, with Silk Cut sponsorship and factory backing, took everything that Fabcar and Bob Tullius's infamous Group 44 had learned in their Jaguar GTP program and began assaulting Porsche's dominance. In 1987, they won Le Mans, and they did it again in 1988.
Layla's Keeper1988 was also the year we saw the emergence of Toyota's 88C program, Nissan's series of Group C prototypes, and the Sauber-Mercedes alliance that led to an overall victory in 1989.
1989 being one of the hardest fought 24 Hours of Le Mans in history and also the debut of the Aston Martin AMR1.
By 1989, the 962's saving graces were reliability and strength in numbers. But the speed of the massive factory efforts of Nissan, Mazda, Toyota, Jaguar, Mercedes, and Aston Martin were proving more than the stretched 956 could handle.
1990 was another year of Jaguar triumph, and 1991 proved to be the grand fluke as Mazda's 787B came from 19th on the grid to win a mechanical failure laden 24 Hours, with all three Jaguars right behind it.
Layla's KeeperHowever, it must be noted that 1991 was also the year of the "category split" in Group C that was intended to introduce a more modern form of the Group C prototype with less reliance on turbochargers and downforce. The primary Category 1 cars were the new Peugeot 905's, while most everything else was a Category 2 car.
Layla's KeeperUnfortunately, the die was cast. 1992 was contended primarily by Cat. 1 cars, and the only Cat. 1 cars with realistic chances of winning were the Peugeots. Toyota's TSO10 put up a gallant fight to take 2nd, and Mazda's swan song in prototype racing, the Judd V10 powered MXR-01, captured a solid fourth, but only Toyota would return the next year to contend with Peugeot.
By 1994, all that was left of the mighty Group C class was a mishmash of prototypes titled "LMP1/C90". Expanded rules in the GT1 class, coupled with Dauer's run of "street legal" 962's, meant that a pair of Porsche 962's were able to run the GT1 class, where it claimed the final victory at Le Mans for a Group C car.
Layla's KeeperYes, Greycap, the Group C (and even moreso their GTP cousins) cars were - and to a degree still are - the absolute pinnacle of sports car racing. Their speed, grip, and braking was unparalleled until the GT1 movement of the late 90's. It took extreme driver skill to haul ass in a Group C or GTP car.
After all, where do you think Schumi got his start?
Sauber-Mercedes C-11, 1991. Karl Wendlinger, Michael Schumacher, Fritz Kreutzpointner. 5th overall.
crimson_menaceGroup C Club...
If the XJ220's are in, then count me in! Whoooooooooo!!!!!!1!!one...!!!!!!
👍
nitro_2005and i know that the engine from the xj220 was developed from the engine used in the jaguar xjr-9, a group-c car i believe. jaguar actually used and develope the engine from the metro 6r4 and used it in the xjr9 first, before developing ot for the xj220. ah, what would i do without my "too fast to race" dvd?
THE ED3i'm no expert on this type of racing as i wasnt old enough when these cars were around to watch but i love the way the cars look, i love daytona prototypes and LMPs... the cars in gt4 are fun to.
Gil AbobeleiraDaytona what??? Oh, those spec "medieval-times" ca4s
