In April the diesel offered for 204 Break was increased in size to 1357 cc and become also available for the Furgonette.
In April, because of the oil crisis Peugeot presented the 504 L. It feature a live rear axle and a smaller 1,796 cc engine rated at 79 bhp (81 bhp for Automatic).
304 Cabriolet and Coupé were withdrawn from the market, without direct replacements, respectively in July 1972 and August 1973.

Introduced at last year's Paris Motor Show, the Peugeot 104 marked a return by the oldestablished French manufacturer to small cars, indeed to the smallest four-door saloon currently in production. The 104 is only 11ft. 10in. long but will accommodate four, and the luggage boot is surprisingly large. The light-alloy engine is set transversely at the front, and drives the front wheels through a four-speed gearbox with all-indirect gears. Although of less than one-litre capacity, the 104 will touch 85 m.p.h., and accelerate from a standstill to 50 m.p.h. in 12 seconds.
The front-drive Peugeot 304 saloon uses the same basic body shell as the smaller-engined 204, so it has a performance plus. The engine is a four-cylinder overhead camshaft unit mounted transversely at the front of the car where it is inclined at 20 degrees to reduce bonnet height and to lower the centre of gravity. It is a lively, well finished car with excellent ride and handling qualities. Besides the saloon there are also Cabriolet, Coupé, and Estate versions, the latter being a very commodious vehicle for 1.3 litres. They come from one of the world's oldest-established motor factories.
Unlike the smaller Peugeots, the 504 has its engine mounted longitudinally at the front where it drives the rear wheels.
Diesel engines are attracting increased attention as a means of cutting fuel costs and Peugeot have put one in their 504 L saloon. The L is the lowest-priced version of the 504, with a rigid rear axle, radius arms and coil springs instead of independent rear śuspension. Mechanics from alt Peugeot dealers have already been trained to service the diesel which should be specially attractive to commercial users doing big mileages.
The two 504 Estate models derive from the saloon, but have a longer wheelbase (9ft 6in. compared to 9ft.), greater overall length (15ft. 9ins. compared to 14ft. 8½in.) and a much greater load capacity. The Estate is a five-seater, and the Family Estate a seven-seater. Both cars are powered by the 1971 c.c. engine, and both will approach 100 m.p.h. The 504 Estates have a completely difierent rear suspension from the saloon models.
