Very
shortly afterwards, the car was fitted with a Renault 8 Gordini engine,
and achieved several excellent results in Formula Libre in the hands
of Roger Cohen, the "works" driver. It even took overall honours against
Formula 3 single-seaters!

The
commercial success of the Barzoi shouldn't detract fron its competition
success: Francois Lacarrau took second place in the 1968 Grand Prix
de Paris at Montlhery, against such well-known names as Servoz-Gavin,
Wicky, Jungenet etc armed with Matra 470BRM, Ferrari, Porsche 906's
etc !
Sport-Auto
remembered it as a "David versus Goliath" race, with the little
Barzoi, powered by a 105 Bhp R8Gordini engine, up against cars with
250 to 400 Bhp!

In
1970 Marcel Fournier retired, leaving Andre Marcadier to continue
working away. In the same year he produced a two-seater sports-racer
specifically for competition, and which used the Barzoi as its base.
This model, called Can-Am after the American cars which inspired
its appearance, was the first of a series which allowed talented
amateur drivers to have a real competition sports racer at a budget
price.
Thus,
at the 1975 French mountain-climb championships, Marcadiers,
powered by Renault 8 Gordini 1300cc engines, finished 4th and
5th, up against Formula 2 single-seaters and 2-litre prototypes!
The
1978 season brought even greater success in what was already
becoming a more "professional" discipline: Marcadier's final
creation, an elegant sports racer powered by a 300 Bhp Ford-Hart
2-litre engine,totally dominated its class and even worried
the Formula 2 single-seaters which, due to their handling
and low weight, were the quickest cars on the mountains.
The
driver was not altogether unknown: Roger Rivoire had been
an apprentive at Fournier-Marcadier who, in 1974, had come
very close to becoming French mountain-climb champion).The
low-budget but talented Marcadier/Rivoire combination won
its class on 11 out of 14 events: in the 3 other events
the car was using an engine which was "past its prime".
In
early 1967, a brilliant develpoment of the open-top sports car emerged
from the Lyon workshops: this was the unforgettable Barzoi.It took
its mechanicals from the earlier model, but had a roof and doors incorporated,
to cater for buyers who wanted a more usable car. Like the Mercedes
300SL, it had gull-wing doors because of its tubular chassis and low
height
