What is it? Quiz #469

This is a 1927 Grofri 4/20 PS Type A, a licence-built Amilcar CGS from Atzgersdorf, Austria. Grofri (Gross & Friedmann) started in 1921 with building six-cylinder cars, but turned to producing these Amilcar-based light cars from 1925 to 1927, mostly without mentioning their technical origin. The bodywork was strengthened because of the Austrian roads, some racing cars were fitted with Roots superchargers. The picture shows the German crown prince Wilhelm 1927 in Vienna. After a test drive he bought a silver Grofri Sport, which had a Riccardo cylinder head for higher output.

Well this must be a 1926 or 27 Grofri. Austrian Company from Gross and Friedmann. Most likely a licence of Amilcar 4C. They were from 1921 to 1931 in the business, had 4 and 6 cylinder cars of their own design and from 1924 to 27 made these little sportscars under licence from Amilcar. The company resided in Atzgersdorf near Vienna and was named Grofri Werke AG. They also build farming equipment.

This Austrian Grofri was the result of Robert Gross and Leopold Friedmann. Their first model in 1922 was a 6 cyl car, which was succesfull in local races. From 1925 onwards small sporty 2 seaters, made in “lizenz” after the French Amilcar were built. These affordable sports-cars qualified in numerous Hillclimbs and some equipped with a Compressor, special cylinder-head and brakes on all 4 wheels could reach a top of 85 miles. Even three- and four-seat models were built, but looked nowhere near the the lean and sleek 2 seater models. Production ended in 1927

Dear prewarcar-team,

enjoy the early-summer-days.

Here the solution to Quiz #469:

Grofri Werke AG, founded in 1921 in Vienna-Atzgersdorf by GROss and FRIedmann, started with a large six-cylinder Tourer (12/40HP), which could also be moved sportive (1922 Ries race at Graz: First Prize 3.5 class).
In 1925 Grofri acquired the Amilcar-CGS-license. It was offered with 4/20HP four-cylinder-inline-engine with 1074ccm, three-speed-gearbox, with and without compressor, with 2- and four-wheel brakes as well as 2, 3 and 4 places.
We see the visit of the German ex-Crown Prince Wilhelm in September 1927 in Vienna. After a test drive he bought such a 4/20PS-Grofri in silver-gray. At the end of 1927 Grofri stopped production.

Austrian built Amilcar - Grofri

I think it looks like a GROFRI Amilcar made under license in Austria.
To check my opinion I googled Wikipedia.


Grofri was the brand of cars manufactured in Austria from 1921 to 1931 (1924 to 1927 under the licence of the French Amilcar). SV 903 cc or 1074 cc four-cylinder engines were used in these sporting cyclecars. Racing versions were also made, some of them with Roots superchargers.

Austrian car Grofri 4-24-40ps Super Sport Kompressor 1927 year. License of Amilcar.

Austrian Grofri, a licence-built Amilcar CGS named after Robert Gross and Leopold Friedmann. In Atzgerdorf they built the 1,1-litre French-based sportscar from 1925, before that larger touring cars were produced. Racing versions with blowers were also offered. Factory driver was Max Hofman the man behind Porsche 356 Speedster and BMW 507

It's a Grofri, made about 1927 near Vienna / Austria. It's the Austrian equivalent of Amilcar's famed CGS with 1,074cc side valve four-cylinder engine.
