Engine alternatives in ”The Triplets” (Toyota Aygo, Citroen C1 and Peugeot 107)

Two engines has been available to choose between, however I not sure the Toyota is available in diesel anymore..? Inputs is appreciated.
  1. 4 cylinder 1.4 liter diesel engine: 2WZTV engine, (PSA developed)
  2. 1 liter (996 cc), 3 cylinder petrol engine: 1KR-FE engine
My own interest is in the petrol version, so here goes:
The engine is assembled in Poland or Japan (according to wiki)
The engine comes from Toyota, but is designed by Daihatsu. The engine has been chosen “International Engine of the Year” 2007-2010 in the sub category below 1 liter engines.
The engine uses a Timing chain, so you won’t have to replace a belt. The chain will probably last many years before starting to get noise and will need to be replaced. The engine block is made of aluminum and uses Double Overhead Cam (DOHC). The fuel injection system is “multi-point”.
It has VVT-i technology and has 4 valves per cylinder (twelve in total). It produces 50 kW, which equals 50*1,36=68 Swedish Horse powers (hkr). It doesn’t produce mush carbon dioxide footprint either. Here in Sweden it is a “environment friendly car” and the road tax is therefore low on this type of car.
The engine is used in the following cars:
Daihatsu Sirion
Toyota Aygo
Citroën C1
Peugeot 107
Toyota Yaris (1 liter version, called Vitz in some parts of the world)
Toyota IQ
Subary Justy (2008-)

The engine is really small and weights only about 69 kg. Some Internet pages say 67 kg. Perhaps this number is without accessories.
