World Record #22 - the most economical car in the world

This is a “real car” in the sense that it is road-legal. But it never made it into production:

Volkswagen 1 Litre

From the article:

The 1-litre car is powered by a one-cylinder diesel engine, centrally positioned in front of the rear axle and combined with an automated direct shift gearbox. The crankcase and cylinder head of the 0.3-litre engine are of an aluminium monobloc construction. The naturally aspirated, direct-injection diesel engine employs advanced high-pressure unit injection technology to generate 6.3 kW (8.5 bhp) at 4,000 rpm. This gives the vehicle, which weights just 290 kg, an astonishingly lively temperament.

Fuel consumption is a mere 0.99 litre per 100 kilometres. With a 6.5-litre tank, this gives a range of some 650 kilometres without refuelling.
