When Perodua launch its new model Axia recently, one of the most interesting fact is the new engine they are using under code of 1KR-DE2.
Most of us noted that Perodua Axia is base of underpinnings Daihatsu Ayla and Toyota Agya model, but it seem the previous engine code is stated 1KR-FE, after that 1KR-DE is launched and the latest is 1KR-DE2, here some fact from Wikipedia website,
1KR-FE[edit]
The 1KR-FE is a 1.0 L (996 cc) version built in Japan and Poland. Bore is 71 mm and stroke is 84 mm, with a compression ratio of 10.5:1. Output is 67 PS (49 kW) at 6000 rpm with 91 N·m (67 lb·ft) of torque at 4800 rpm or 71 PS (52 kW) at 6000 rpm with 94 N·m (69 lb·ft) of torque at 3600 rpm. When originally on sale it met European emission standard EU4 requirements and had CO
2 levels of 109 g/km, but current applications meetEuropean emission standard EU5 and can have CO
2 levels as low as 99 g/km.[1] This engine has been given the 2007, 2008, 2009 and 2010[2]International Engine of the Year awards in the sub-1.0 liter category.

- Toyota Vitz/Yaris (2005–)
- Toyota Belta (2006-2012)
- Toyota iQ

- Subaru Justy (2008-)
- Toyota Wigo (2014-)
1KR-DE[edit]
The 1KR-DE is the non VVT-i variant of the 1KR engine. It produces less power and torque than 1KR-FE. Output is 65 PS (48 kW) at 6000rpm and 85 N·m (63 lb·ft) of torque at 3600rpm. Bore is 71 mm and stroke is 84 mm, while the engine displacement is 1.0 L (998 cc).[3][4]
The 1KR-DE was specially designed for the Indonesian LCGC (Low Cost Green Car) market to reduce cost. The engine cylinder head cover is made from plastic-resin instead of aluminium to save 10 kg of weight. The exhaust manifold is integrated to the cylinder head together with the catalytic converter and oxygen sensor to save even more weight.[5]
Applications:
- Toyota Agya/Daihatsu Ayla (2012-)
1KR-DE2[edit]
The 1KR-DE2 is the more powerful variant of the 1KR-DE engine which is redesigned by Perodua. It produces 66 PS (49 kW) at 6000rpm and 90 N·m (66 lb·ft) of torque at 3600rpm. Like the 1KR-DE, bore and stroke are at 71mm and 84mm respectively, and engine displacement remains at (998 cc)[6][7] The 1KR-DE2 achieves Euro IV emission standard, but still lacks VVT-i when compared to 1KR-FE. The compression ratio for this engine is 11:1.[8]
Applications:
- Perodua Axia (2014-)
