Rosa wins the Eifel-Rennen with Alfa Romeo

by Hans Etzrodt
There were 12 starters in the modest racecar class, divided into four classes. The large cars dominated the race where Taxis (Alfa Romeo) held the lead until lap five. Ludewig (Bugatti) then was in first place for two laps to be passed by Rosa (Alfa Romeo) who led on lap seven before Ludewig regained the lead which he held until lap 13 when he ran into trouble. Rosa then led the remaining laps and battled with Kaufmann (Steiger), who charged too late. Rosa won after 15 laps with Kaufmann second ahead of Ludewig and Tatenhorst (Dürkopp). Rosenberger in a 1924 Benz Monza type held fourth place before he retired on lap five. Taxis crashed on lap eight, Schulz (Bugatti) crashed near the end causing the death of his passenger. There were eight finishers on this cold rainy day.
The Eifelrennen at Nideggen was first held in 1922, again in 1924 and the 1925 event was the third running. The official name was Eifel-Rundfahrt, which changed in 1924 to Eifelrundfahrt and to Eifel-Rennen in 1925. The ADAC organized the races to win the German Tourist Trophy including three prizes for each class. The circuit remained the same since 1922 with the start at Nideggen, leading clockwise through the towns of Berg, Wollersheim and Vlatten, then continuing through Heimbach, Schmidt and Brück from where it was just 2 km to Nideggen, completing the 33.2 km lap. The undulating mountain course with 80 turns was also referred to as 'The German Targa Florio'. The races for motorcycles, touring-, sports- and racecars were held for three days. This report limits itself to the racecar event, held on Friday, June 19.
The race became disappointing and interest lessened after the Mercedes team had withdrawn, also Hans Kolb with the Grand Prix Bugatti and Max Buchholz, who according to the report, had his 1500 Mercedes racecar stolen in Cologne a few days before the race. Most entries were in the 2000 class, including T30 type 8-cylinder Bugattis by Ludewig and 60-year old Schulz, two Dürkopps by Volkhart and Tatenhorst, Rosenberger with a 1924 Benz RH "Monza" and Gustav Münz with his 2-liter 4-cylinder Ford Spezial which he had built himself on a Ford chassis. He was a garage owner and Ford dealer in nearby Düren. Before WW I, he had worked for 11 years at the Mercedes factory and was a mechanic preparing Otto Salzer's racecar in the 1908 French Grand Prix.
      In the smallest class for 1.1-Liter cars was only Conrad Mederer, a manager of the Cologne Opel branch, with a little Opel Laubfrosch, which was not a racecar. In the 1500 class were the young Lammertz with a supercharged 6/25/38 Mercedes touring car without 4-wheel brakes and a supercharged 1300 NSU of Josef Müller.
      The over 2000 class comprised two 6-cylinder Alfa Romeos of Taxis and Rosa to fight against the Targa Florio Steiger of Kaufmann. The entries are also listed at the beginning of this report.
It was a cold and unpleasant morning with fine drizzling rain and a coolness in the air. The racecourse was still in excellent condition but steady drizzling rain caused fears that the roads would become slippery. Compared with the motorcycle races of the day before, there were less spectators.
      The start of the 12 cars began at 6:12 AM in Nideggen when the starter lowered the red flag for the first car, Taxis (Alfa Romeo). The cars were released separately at intervals of one minute between each car. Rosa (Alfa Romeo) was next, then Kaufmann (Steiger), followed by Ludewig (Bugatti), Tatenhorst (Dürkopp), Volkhart (Dürkopp), Rosenberger (Benz), Schulz (Bugatti), Münz (Ford), Lammertz (Mercedes), Müller (NSU) and Mederer (Opel) last.
      After the first lap, Taxis (Alfa Romeo) had a time of 27m08s. The order in which the cars passed the grandstand was the same as they had started except that Rosenberger in the Benz had passed the two Dürkopp cars. Mederer (Opel) took 34 minutes. Münz (Ford) was overdue. After 48 minutes he had still not passed the finish area. A few minutes later it became known that the Ford had slowly left the road, probably with an engine problem, just short of Brück which was only two km ahead of the finish. Unknown to the general public Münz worked intensely on his Ford engine to bring it back to life.
      At the end of the second lap at 7:07 AM, Taxis, Rosa, Ludewig and Kaufmann passed close together at the turn of the grandstand. Taxis' time for the first two laps was exactly 55 minutes, while Ludewig used less time with his Bugatti. Rosenberger in his Benz arrived only at 7:16 AM, so he took 64 minutes for two laps. Volkhart arrived at 7:18 AM, close behind him was Müller from class II. Schulz arrived at 7:20 AM, Lammertz at 7:24, Mederer at 7:28 and Tatenhorst at 7:30 AM.
      After the third lap at 7:35 AM, Taxis arrived with a lap in 26m47s. At 7:37 AM passed Ludewig, who had made a very good time, followed by Rosa and Kaufmann. The times achieved were considered good, as the roads had become slippery. The hope for better weather was in vain, as it began to rain heavily. Suddenly at 7:55 AM, loud shouts from the crowd announced the appearance of the lost Münz (Ford), who completed his first lap. Just minutes earlier, Rosenberger, Mederer and Schulz had passed the grandstand.
      After four laps exactly at 8:00 AM, Taxis passed with a lap in 26 minutes. Three minutes later arrived Rosa and Kaufmann. Rosenberger, who passed at 8:17, took 28m08s but did not advance. Schulz drove unsafe, at the lower turn, where he hit the road edge but escaped safely. Lammertz had a defect at the same place and Münz (Ford) nearly collided with him but avoided an impact in the last moment. At 8:30 Müller and Volkhart passed through. All drivers except Mederer and Münz had completed the fourth lap.
      After five laps, the lead changed when Ludewig arrived first, after a lap in 28 minutes. Rosa and Kaufmann followed with Taxis now fourth with a lap of 34 minutes. His best time so far was 26m40s. At 8:45 AM Rosenberger retired at Hasenfeld due to a gear shifting defect. Schulz was the oldest driver in the field, supposedly over 60 years old. At 8:52 AM he was sliding passed the grandstand in fifth place after 30 minutes. At 8:56 AM passed Lammertz and one minute later Volkhart with a time of 28m05s. The best times of the Class leaders after five laps were as follows:
      Class I Mederer (Opel) 2h55m35.2s.
      Class II Lammertz (Mercedes) 2h35m31.2s.
      Class III Ludewig (Bugatti) 2h16m12.1s.
      ClassIV Kaufmann (Steiger) 2h18m58.3s.

      At the end of lap six at 8:59 AM, passed Ludewig in first place with a lap of 27 minutes. One minute later appeared Rosa with the same time. At 9:01 AM passed Münz, at 9:03 AM Kaufmann and four minutes later Tatenhorst. Taxis finally arrived at 9:11 AM with a lap time of 37 minutes when he completed his fifth lap. At 9:23 AM appeared Schulz who had driven insecurely several times. Volkhart passed at 9:24 AM and took 28 minutes. Lemmertz passed at 9:26 AM after which the new leader of the seventh lap arrived.
      After seven laps Rosa was the new leader, one minute ahead of Ludewig. Kaufmann passed at 9:31 AM. Münz passed next with a lap in 30 Minutes. Rosa was leading Class 4, Ludewig Class 3 and Lammertz Class 2. At 9:37 AM appeared Tatenhorst, already on lap behind. The best lap time until now was made by Taxis (Alfa Romeo) in 26m31.8s. He was now in fourth place and had dropped to third position in his class as he passed at 9:42 AM to begin his eighth lap. At 9:55 AM Mederer passed closely followed by Volkhart.
      After eight laps at 9:56 AM, Ludewig passed first with a lap in 27 minutes. Kaufmann followed at 10:00 AM and Rosa in third place passed 5 minutes after Ludewig. Müller, already lapped, completed his seventh lap at 10:01 AM, Lammertz likewise. At this time, Schulz also completed his seventh lap. The Ford of Münz took 33 minutes and arrived at 10:04 to start his sixth lap. Taxis had crashed at Hasenfeld, suffering a broken leg while his passenger escaped without injuries.
      At the end of lap nine at 10:23 AM, Ludewig passed with a lap in 27 minutes. Kaufmann in second place passed at 10:26, Rosa at 10:29, Lammertz at 10:31, Schulz at 10:32 who took 31 minutes. At 10:40 passed the two Dürkopp cars which were one lap behind. Münz passed at 10:50 with a lap of 46 minutes.
      After the tenth lap at 10:51 AM, Ludewig was still leading, with a lap in 27 minutes. His lead over Rosa was just over four minutes. At 10:55 AM Rosa and Kaufmann passed the grandstand, the latter in 29m11s. Lammertz, who was one lap behind, arrived at 11:00 AM, Schulz likewise. A short time thereafter passed Mederer in the Opel to start his ninth lap. At 11:12 AM appeared the two Dürkopp cars. The best times of the Class leaders after ten laps were as follows:
      Class III Ludewig (Bugatti) 4h36m00.4s.
      Class IV Kaufmann (Steiger) 4h41m34.6s.

      After lap 11 at 11:19 AM, Ludewig was still first with a lap in 28 minutes. Rosa followed 3 minutes later with a lap in 26m24,4s, the fastest time so far. Kaufmann who had been ahead of Rosa on lap nine was now third. At 11:25 AM Müller completed his ninth lap, and at 11:31 AM Münz passed the grandstand to begin his 8th lap after he made his 7th lap in 41 minutes. Schulz passed at 11:32 AM to begin his eleventh lap, Lammertz did likewise. At 11:36 AM passed Mederer who was beginning his 10th lap, the last one he had to do in Class I. Volkhart arrived at 11:37 AM after a fast lap in 26m50s and Tatenhorst arrived at 11:42 AM.
      At the end of lap 12 at 11:47 AM, Ludewig passed first with a lap of 12 minutes and one minute ahead of Rosa. At 11:53 AM passed Kaufmann followed at 12:00 PM by Münz with a time of 29 minutes. At 12:02 PM, Lammertz began his 12th lap, his last one in Class II. At 12:05 passed Volkhart who drove his lap in 27 minutes. At 12:09 PM, Mederer the Class I winner crossed the finish line with a time of 5h45m34 s. At 12:13 PM passed Tatenhorst, third in Class III, followed by Schulz, fourth in Class III.
      After lap 13 at 1:14 PM, Rosa was leading with a lap of 27 seconds. At 12:19 PM, Müller began his 11th lap. He had fallen behind when he had to change tires and valves four times. Simultaneously arrived Kaufmann, five minutes behind Rosa, who had made a new best lap in 26m19.2s. At 12:25 passed Ludewig, who had some defect. At 12:30 PM passed Münz with a lap in 29 minutes. At 12:35 PM, Lammertz (Mercedes), winner of Class II, crossed the finish line after completing 12 laps in 5h15m23.8s.
      At the end of lap 14 at 12:41 PM, Rosa passed after a lap in 27 minutes and began his last lap. He had a 5-minute advantage over Kaufmann. In the meantime, Tatenhorst and Schulz had passed the grandstand. At 12:57 PM passed Ludewig to begin his last lap. A 1:00 PM passed Münz with a time of 30 minutes. Volkhart took for this lap almost one hour.
      After lap 15 at 1:08 PM, Rosa (Alfa Romeo), winner of class IV, crossed the finish line, completing the 498 km in 6h54m48s with Kaufmann (Steiger) in second place after 6h58m24.2s. On his final lap Kaufmann also made the fastest lap in 26m16.2s. At 1:27 PM Ludewig (Bugatti), Winner of Class III, crossed the finish line after 7h12m03.2s. At 1:42 PM Tatenhorst who had passed Schulz, passed the stand to begin his last lap. Schulz was reported to have crashed in one of the turns and his injured passenger died.

In retrospect:
This report would not have been possible without the help of Marco Kieser who did a lot of research in Aachen and Düren and found the snippets of the Dürer Volkszeitung which provided the details to produce most of the content in the report. Credit goes also to Hugo Boecker who sent these and other reports to us and also to the journalist who wrote the reports.

The ADAC timekeepers generated poor and incomplete information reported in the Dürer Volkszeitung and used in our report. There is dispute regarding the final times for Ludewig, Lammertz and Mederer:
      Ludewig (Bugatti) finished after 7h12m3.2s. Also mentioned was 7h55m05s and 7h55m05.4s.
      Lammertz (Mercedes) finished after 6h23m00.8s. Also mentioned was 6h15m28.8s and 6h15m23s.
      Mederer (Opel) finished after 5h45m34s. Also mentioned was 5h45m37s.

Although the race was held to determine the fastest driver, the time keepers were incapable to provide the speeds attained. We calculated the speeds afterwards for fastest lap and class winners.

Ginaldi wins the Coppa Acerbo with Alfa Romeo

by Hans Etzrodt
The 26 starters at the Coppa Acerbo included 7 Bugattis, two Alfa Romeos, three Fiats, one each Itala Special, OM, Chiribiri and many others. Materassi (Itala Special) had the fastest car but never-ending tire failures set him back and allowed the trouble-free Alfa Romeo of Ginaldi to hold the lead. When second placed Bertocci (Alfa Romeo) pitted, Minciotti (Bugatti) took his place on lap 10. Materassi carried on with his fast sprints interrupted by tire stops until he ran out of tires and ended his race on lap 17. Ginaldi won ahead of Minciotti, Croce (1500 Bugatti), Balestrero (2000 OM), Weber (1500 Fiat), Clerici (1100 Salmson), Platè (1500 Chiribiri), Fagioli (1100 Salmson), Lagorio (1100 Amilcar) and Sandonnino (900 Citroën). Three drivers exceeded the maximum time and 13 retired.
The Automobile Club di Pescara held the 1925 Coppa Acerbo for the second time. In 1924 Minister Giacomo Acerbo had named the race in honor of his brother Capitano Tito Acerbo, a decorated war hero, who was killed during the last year of WW I. The same triangular 25.5 km Pescara circuit was used, over 20 laps or a total of 510 km for all cars. The start was at Castellammare, north of the seaside resort of Pescara, where the road went straight for about one kilometer along the shore of the Adriatic Sea. Before Pescara the course made a wide right turn heading inland for about 11 km along a winding road up into the Abruzzi Mountains through the villages of Villa Raspa, Spoltore and Capelle. From here, the road led into the approximately 11 km long Montesilvano downhill straight to the coast where cars could reach their maximum speed. A right turn at Montesilvano railroad station led into the Lungo Mare straight along the coast and back to the start and finish at Castellammare.
      The entries were divided into five categories, over 2000 cc, up to 2000, up to 1500 cc, up to 1100 cc and up to 900 cc. The Pescara Automobile Club had a total prize fund of 108,000 lire. The overall winner, who completed the race in the shortest time, received the Coppa Acerbo and 50,000 lire. In each of the five categories the winner received 6,000 lire and a gold medal, second 4,000 and third 2,000. The fastest lap of the race was awarded with a gold medal by Mussolini.
The Coppa Acerbo promoters received a total of 39 entries but only 26 drivers, all independents, started in this national event. The favorites besides Materassi in the 5.8-L Itala Special were the 3.0-L Alfa Romeos of Bertocci and Ginaldi, the 2-Liter Bugattis of Minciotti and Antonelli and the OM of Balestrero, all candidates for one of the leading positions. Materassi's Itala Special had only a few Itala parts (clutch, gearbox and transmission) so to call it an Itala 55 Special, as it is often done, is misleading. The car had a custom-built chassis and suspension, but it was called an Itala for publicity reasons as Materassi owned the Itala agency in Florence. The engine was half of a V8 Hispano-Suiza aircraft engine so the capacity was about 5.8 liters. The source of the figure of precisely 4722cc which is to be found in contemporary motor sport literature is a mystery. This is explained in Alessandro Silva's article about Italian aero-engined specials, which was published in The Automobile magazine. A complete list of entries is shown at the beginning of this report.
Sunday at 8:00 AM the stands were already crammed with spectators and crowds were all along the circuit. Only 27 cars entered the track, stopped at the pits, waiting to take place on the grid. Ruggeri's Alfa Romeo broke the cam drive chain when driving to the pits forcing him to give up. The starting area was cleared as the now 26 cars lined up on the grid. The start was in order of the race numbers with an interval of two minutes between each category.

The starter General Attilio Teruzzi, assisted by timekeepers Marley and Celpi, lowered the flag at 9:00 AM to release the three large cars of Category V when Materassi shot into the lead. After an interval of two minutes, the three cars of the Category IV were started.

After a break of two minutes it was the turn of the nine cars of Category III up to 1500 cc, but the order of the line-up is not quite clear. The following cars started but not necessarily in this order: De Bernardinis (Fiat), Weber (Fiat), Nardi Pelagalli (Bugatti), Platè (Chiribiri), Montanari (Bugatti), Paris (Bugati), Spinozzi (Bugatti), Croce (Bugatti) and Ciriaci (Bugatti). After a two-minute interval, the seven cars of Category II were flagged away.

After another 2-minute interval, the cars of Category I were flagged off, which were the four Citroëns of Favia, Sandonnino, Serventi and Sorrentino, but the line-up of this group remains unknown.
      After the start Materassi assumed the lead until just five kilometers from the start at Villa Montani, when he stopped to replace a tire. Ginaldi passed him and at the end of the first lap was first after 16m09.4s. Materassi was chasing after Ginaldi and produced a spectacular run-up in second place. Bertocci, who followed in third place drove at a lesser pace and lost ground.
      Materassi caught up with Ginaldi during the third lap and easily passed him along the first straight. But a rear tire thread separated again and forced Materassi to stop losing the lead again. Weber had a long pit stop due to carburetion problems while Platè was struggling with spark plug trouble. In the meantime, Antonelli's Bugatti retired and Ciraci walked back on foot after the gearbox breakdown on his Bugatti. Sorrentino with his Citroën also retired.
      During the fourth lap, the two Alfa Romeos of Ginaldi and Bertocci were in front but the latter was heavily delayed. Materassi was gaining and his comeback was spectacular. When the Bugattis of Spinozzi and Nardi Pelagalli retired, Croce in another Bugatti, then took the lead in the 1500 class and climbed to fifth place overall. Clerici (Salmson) was first of the 1100 class and Sandonnini (Citroën) led the 900 class. Ginaldi and Bertocci headed the field with Minciotti in his 2000 Bugatti in third place, just four minutes behind Ginaldi. The field was down to 21 cars with the following times of the leaders after 5 laps:
1.Ginaldi (Alfa Romeo)1h19m10.8s
2.Bertocci (Alfa Romeo)1h21m25s
3.Mincicotti (Bugatti) 1h23m10s
4.Materassi (Itala Spl.)1h30m49s

On the 7th lap Minciotti made the record lap for the 2000 class with 16m31.2s at 94.328 km/h. During lap 6 and 7 Materassi was safe from tire problems, using his mechanically intact Itala with superior speed to catch up with the leading Ginaldi. Favia's Citoën retired on the 7th lap and Vaghi's SAM was also out of the race.
      During the 9th lap, Borzacchini retired his Salmson. Materassi made the fastest lap of the race in 14m04s at 108.778 km/h average speed and exceeded the 1924 record of Bonmartini (Mercedes) in 14m05.4s at the average of 108.778 km/h.
      On the 10th lap, mid race after 255 km, the 18 cars still in the race began their refueling stops. While Bertocci's Alfa Romeo lingered in the pits with an ignition problem, Miciotti with the 2000 Bugatti took over second place. Once the problem was fixed, the Alfa Romeo resumed the race, but with the engine still not running properly, Bertocci retired on the 11th lap.
      Materassi was struggling once again with replacing tires, whose supply in the pits was being reduced at an alarming rate. The Ginaldi-Materassi duel intensified but the battle continued at a rather uncertain level. As Ginaldi maintained his very regular pace with long stretches in the Alfa Romeo, Materassi delivered dizzying high-speed runs in his Itala Special, interrupted by tire failures with pit stops. After the retirements of Serventi's Citroën on the 13th lap, Bepi Crespi's SAM on the 15th lap and Montanari's Bugatti 1500 on lap 16, Materassi began his 17th lap. He no longer had spare tires on board, since the stock in the garage was used up. The seventeenth tire failure happened and Materassi's race ended along the route.
      There were only three laps left at the end of the race and the spectators finally realized that the leader was a driver from Abruzzo. At the end of the 20th lap, Ginaldi victoriously crossed the finish line in his Alfa Romeo. Minciotti in the 2.0-L Bugatti was second, almost nine minutes behind, while Croce in the 1500 Bugatti was over one lap down, followed by Balestrero, Weber, Clerici, Platè, Fagioli, Lagorio and Sandonnino the last finisher in tenth place. De Bernardinis, Paris and Luigi Crespi did not classify as they exceeded the maximum allowable time but completed 16 laps or more.

In retrospect:
We had to settle controversy. Two of our sources claimed that there were 40 entries, 27 starters and 10 cars were classified. But none of our six contemporary sources listed the 27 starters. The book by Santuccione & Smoglica, was the only source listing 26 starters of which they classified 9 finishers, 4 did not classify and 13 retired. After deleting one duplication, we counted 39 entries, 26 starters, 10 finishers, 3 did not classify and 13 retired.

      The timekeepers must have had a difficult time, since the final classification times published in our six sources deviated often by large margins. We hope that we have selected the correct times.
