Champion

Also known as ZF Champion, Champion 400, Champion 400 H

It began in 1946 as a design study at a gear works: a doorless two-seater. Over the next eight years it grew doors, a roof and a water-cooled twin, and passed through five firms, repeated insolvencies and one owner who disappeared, before Maico bought what was left.

Drawn at true proportion. The track is 3.6 metres long; the adult stands at the same scale. The Peel P50 is the smallest production car, on every page for comparison.

The story

History

Zahnradfabrik Friedrichshafen, ZF, was, as its name says, a gear works. In the summer of 1946 its chief engineer, Albert Maier, drew up a small car: a doorless two-seat roadster 1,980 mm (78 in) long, weighing 170 kg (375 lb), with a Triumph two-stroke single from Nuremberg of nominally 196 cc, though its 65 × 61 mm bore and stroke actually give 202 cc. It had 5 PS (3.7 kW), a two-speed gearbox and a rear axle with no differential, and it did more than 50 km/h (31 mph). Three to five were built, and it was one of the first small-car projects of post-war Germany.source 1 An ILO engine had been planned; the motoring press reported that the Triumph Gemo 200 had proved itself in testing, thanks to its flat torque curve.source 1

„Hierdurch soll auch der günstige Norm-Verbrauch von 4,5 l/100 km erreicht sein.“

Motor-Rundschau 1948, no. 1/2, p. 18, on the Triumph engine in the ZF Champion, as quoted by German Wikipedia. In English: “This is also said to give the favourable norm consumption of 4.5 l/100 km.”source 1

ZF did not want to develop or build the car itself, so Hermann Holbein took it over, by a contract of 12 January 1949.source 2 German Wikipedia calls him a racing driver; the Weiner museum, a former BMW man who, when BMW in Munich closed its gates after the war, decided to design a car for the masses. Both may be true; no biography of him has been found.source 3source 4 His Hermann-Holbein-Fahrzeugbau, at Herrlingen near Ulm, built a single CH-1 in April 1949: 2,420 mm long, 190 kg, a 198 cc Triumph of 5 PS, still two speeds and no differential, for 50 km/h and 3 litres per 100 km (94 mpg). Its body needed no special tooling, and its wheels came from motorcycles.source 5source 4

The CH-2 followed, two prototypes in June 1949 and a revised series from November: a 248 cc Triumph of 6.5 PS (4.8 kW), three speeds, a body by Karosseriebau Böbel of Laupheim, 2,800 mm and 220 kg, 60 km/h (37 mph), DM 2,650. Eleven were built, and when the first cars developed gearbox trouble Holbein recalled them all for repair.source 6source 4 The 250 and 250 S roadsters of March 1950 to March 1951, 2,850 mm long, with 6.5 or 10 PS, made 267 more.source 7source 8 In Austria Perl built about 100 Champion 250s under licence between 1951 and 1954.source 7

Paderborn and the 400

Holbein’s firm was too small to survive alone. In July 1950 he and Benteler, a steel-tube maker from Bielefeld, founded Champion-Automobilbau GmbH, in a factory on a former military airfield at Mönkeloh, near Paderborn, with about 70 staff.source 3source 2 That May the Berlin motor show had seen the car that would carry the name on: the 400, a two-door convertible saloon with a body by Drauz of Heilbronn and a 396 cc Triumph single of 10 PS. Four prototypes were built.source 9 The Weiner museum describes the result as modern and almost symmetrical, with half-moon side windows that wound down into the doors.source 10

Production began in February 1951, and the car suffered on the way. Benteler wanted to supply as many parts as it could, and the changes to the chassis made the car tail-heavy, spoiling its road-holding and ride. Triumph would no longer supply engines without security, so the series 400 had a water-cooled ILO 398 cc twin of 14 PS.source 11 It cost DM 3,750, then DM 3,995 from July 1952, and 1,904 were built by May 1953.source 11 Rumours of bankruptcy made suppliers fear for their money, and the Weiner museum says a deal with the owner of the Delta refrigerator firm kept things going.source 10

Ludwigshafen, and a disappearance

In December 1952 a Champion dealer, Hennhöfer & Co. of Ludwigshafen, took over the tooling as the Rheinische Automobil-Fabrik.source 3source 12 When ILO stopped making the engine, the 400 H of June 1953 took a water-cooled twin from Heinkel, maker of the Heinkel Kabine, of 396 cc and 15 PS, with hydraulic brakes.source 13source 10 In July came the first Champion with four seats, the 500 G estate, with a wooden rear body and a 452 cc Heinkel twin tilted at 60 degrees to keep the load floor low.source 14 Hennhöfer stopped in November 1953 after 1,681 cars, owing DM 1.18 million.source 12

Henning Thorndal took over in mid-1954 and built about 300 more by November, meaning to start again in February 1955. Instead he vanished, leaving DM 6 million of debts. In October 1954 a four-seat prototype with its engine in front, driving the front wheels, had been shown; it never went into production.source 15 On the last day of 1954 Ostner Fahrzeugwerke of Sulzbach-Rosenberg, which had hoped to merge Thorndal’s firm with Champion, applied to the court for composition proceedings, as auto motor und sport reported in February 1955.source 16 German registrations of the car had climbed from 106 in 1950 to 1,685 in 1953, and fell to 428 in 1954.source 3 In June 1955 the receiver sold the rights, the assembly equipment, the tools and the stock to Maico, for about DM 300,000.source 3source 15

Maico MC 400

1955–⁠1958 · a record on this page

Maico, of Pfäffingen in Württemberg, kept the Champion going under its own name. The MC 400/H of September 1955 was almost the same car as the 400 H, and 1,374 were built by June 1956, with 21 MC 500 G estates alongside, to December 1956.source 17source 18 In September 1955 auto motor und sport, surveying the smallest cars at the Frankfurt show, still counted the Champion among the names that held the market.

„Beweist, daß sich auch dieser noch so junge Markt im Zeichen von Messerschmitt und Isetta in erster Linie, Goggomobil, Fuldamobil und auch Champion in zweiter Linie bereits so sehr konsolidiert hat, daß kaum jemand den Mut findet, zu den genannten noch in Konkurrenz zu treten.“

auto motor und sport 20/1955, report on the Frankfurt motor show, September 1955. In English: “[It] proves that even this still so young market, under the sign of Messerschmitt and Isetta first, and Goggomobil, Fuldamobil and also Champion second, has already consolidated so far that hardly anyone has the courage to compete with them.”source 19

From June 1956 came the MC 400/4 and the four-seat MC 500/4, with a body by Baur and the 452 cc Heinkel twin of 18 PS, for 95 km/h (59 mph) and DM 3,490. German Wikipedia gives 6,301 MC 500/4s, and no second source for the figure has been found.source 20 Maico advertised it as a fully fledged car and a comfortable four-seater; one source finds it cramped even for two, another says four adults had no complaints.source 20 In September 1957 Beutler bodied four 500 Sport convertibles.source 21 Steering arms began to break. The warranty claims were costly, the car’s name was ruined, and Maico gave up making cars.source 20

Famous for

Three points

  1. Born at ZF

    ZF of Friedrichshafen designed the first Champion in 1946, and built a replica of it in 2005.

  2. Five firms in six years

    Herrlingen, Paderborn, two firms at Ludwigshafen, then Maico: one owner vanished, leaving DM 6 million of debts.

  3. Half-moon windows

    The 400’s side windows were half-discs that wound down into the doors of an almost symmetrical body.

Survivors and collecting

Today

Perhaps two CH-2s survive. The Weiner museum restored one, and a CH-2 is on show at the PS.Speicher, Einbeck.source 4source 6 Of the 400 H the museum could only say that few remain.source 10 When the Hammond Microcar Collection in Kent closed in 2022, four surviving Champions were among the 47 or so cars sold on 27 October (see museums and meets).source 22 One lot was a 500 G in poor condition with a second as a parts car, which made £6,800, about €8,840 with the premium.source 14 ZF published the marque’s history, Hansjörg Dach’s Champion – eine Legende, in 1997.source 1source 3
