Companies like M-Sport, Prodrive, Ralliart or TTE/TMG are well known in the world of rallying, but there was a lesser known satellite operation like this, that once looked promising as well, Mazda Rally Team Europe (MRTE).
The story begins with Achim Warmbold, who was a competent rally driver as his two victories in the first WRC season in 1973 show. For his co driver, current FIA president Jean Todt, these were the first wins on world level as well, but unlike Todt, Warmbold wouldn't win any WRC rallies overall from within the car any more.
Let's jump to 1982, when MRTE was founded by Warmbold as a private team preparing Mazda rally cars. Apparently the company was briefly situated in Geneva of all places, but quickly moved to Brussels. Their first car was a Mazda 323 Turbo homologated in the new Group A class. At the 1982 season opener, the Rally Monte Carlo (RMC) the car debuted in the hands of Warmbold/Cleas Billstam and won its class. Given that the Group A regulations were new and competition was therefore limited, this class win could be considered meaningless. The car itself though, was probably not too bad as it was a sensible base for a rally car thanks to it's compact size, McPherson struts all round and a turbocharged engine. But as the car had very few further outing in the hands of MRTE it's difficult to judge.

Mazda didn't seem interested so far, but the company developed a Group B car based on the ''pedestrian'' first generation RX7 regardless. As a result it utilised the steel production shell, was RWD and had a live rear axle. Given that 4WD was already a thing in rallying and the 037 showed how far you could go within the Group B regulations, the RX7 was not destined to be a winner from the start. The late homologation in early 1984 made life more difficult, as shortly after the first Group B cars that made full use of the liberal regulations started appearing. But at this point it was still a young private operation, so a specialised car was not possible. Outings remained few and far between, with the cars debut being at the Rally Acropolis in 1984. Warmbold/Michele Espinos-Petit, finished 9th and scored the cars first points in the WRC. A year later Ingvar Carlsson/Benny Melander managed to finish 3rd at the Acropolis, this sparked Mazdas interest in the team, but not in the old fashioned RX7.

In late 1985 the 323 4WD Turbo was launched as a hot version of the new 323. Mazda wanted to enter Group A with this car, wich was not a bad idea considering that most successful rally cars that followed were in principle very similar to the 323 4WD Turbo (compact, 4WD, turbocharged, McPherson struts). The only obvious flaws the car had were the 1,6 litre engine and the lack of a centre differential. While it's clear the small engine hindered the cars potential later on, the same can't be said about the missing differential, as the car was lauded for its great handling. The 323 4WD Turbo was only entered for a few events in 1986 with the pairings Carlsson/Jan-Olof Bohlin and Rod Millen/John Bellefleur. The car finished only three times, but Carlsson/Bohlin won the Group A class at the RAC Rally (nowadays called Rally GB) while Millen/Bellefleur managed the same at the Olympus Rally.
As Group A was the new top class from 1987 onwards, few manufacturers were better prepared than Mazda. They already had a season under their belt with a car that seemed perfect for rallying and as a bonus hired the World Champions Timo Salonen/Seppo Harjanne who were the most successful pairing in Group B cars. Most manufacturers entered 2WD or bigger 4WD cars, the only car similar to the Mazda was the Lancia Delta HF 4WD. MRTE was rightfully considered as one of the favourites, and the season didn't start badly as Salonen/Harjane won in Sweden. Warmbold was a rally winner again, only this time as a team principal. But this was as good as it got, the 323 continued to be unreliable (especially the transmission and engine) and MRTE entered only 6 events, not enough to make a meaningful impact on the championship (note that back than it was normal to only enter selected rounds and not the full season for all drivers and manufacturers).

While World Champions Hannu Mikkola/Christian Geistdörfer arguably strengthened the line up in 1988, the situation didn't improve. By now the 1,6 litre engine proved underpowered against the 2 litre competition and reliability was still not sorted. 1989 was better though as I. Carlsson/Per Carlsson won the season opener in Sweden and added to their tally when they won in New Zealand as well. In the end MRTE finished third in the manufacturers championship despite only entering 6 out of the 13 events.
The long awaited new 323 GTX with the 1,8 litre engine and centre differential finally arrived in the middle of 1990 at the 1000 Lakes Rally (nowadays called Rally Finland). Two of the three entered cars retired with engine trouble. Same old, same old. The 323 GTX had reportedly superb handling and was as good to drive as it's predecessor, but that didn't seem to matter at this point any more. MRTE even sent the old 323 4WD Turbo to Rally Australia. In 1991 the same problems kept hampering the team and as a result the 323 GTX never finished a rally on the podium. The only notable thing about the 1991 season would be that Warmbold hired two young talented drivers, Tommi Mäkinen and Jesus Puras. Both of them had their first works outings in the uncompetitive 323 GTX before they went on to have successful careers.

Meanwhile the 323 GT-R was conceived as Mazdas first true homologation special. In principle the same car as the GTX bar some changes, notably a bigger turbocharger which according to Mikkola would have fixed most of the reliability problems, and some redesigned bodywork, primarily front bumper and bonnet. In the wake of the disappointing season, the team sat out the 1992 season to develop the new GT-R which was due to be homologated in 1993. Mikkola seemed hopeful, but it came to nothing. Considering the bad recent results, Mazda withdrew their support of MRTE and the Mazda works team was gone for good. As MRTE was a relatively small operation with limited funds, the team didn't continue on its own either.

The new 323 GT-R was homologated regardless and put to use by privateers, but it was rarley entered as a Group A car. It did however enjoy success as a Group N car and won the FIA Cup for Production Rally Drivers in 1993 as did both its predecessors in 1988 (323 4WD Turbo) and 1991 (323 GTX). The success in Group N is further proof that all 323 variants handled great but both the engine and transmission were to quickly overwhelmed by more power.
It is worth mentioning that MRTE were not the first ones to enter Mazdas in rallies, but they were a professional operation that eventually gathered interest from Mazda and received works status. In the end their lack of success can probably be attributed to limited support from Mazda and a not quite so well suited base car for rallying as many thought.
