Article from wikipedia
"The 1998 incarnation of the Storia/Duet (called Sirion outside of Japan) came with two petrol engines (with multi-point fuel injection): a 1.0 litre 3-cylinder with 54 bhp (40 kW; 55 PS), and a 1.3 litre 4-cylinder 86 bhp (64 kW; 87 PS) unit. Both were available with either a 5-speed manual or an 4-speed automatic gearbox. As of 2001, 1.3L models have 102 hp (76 kW; 103 PS) engines capable of accelerating from 0-60 mph in 9.6 seconds and reaching a top speed of 111 mph (179 km/h). This engine is very fuel efficient with an average rating of 49.6 mpg (21.1 km/l) and the 1.0 model averaging 51.4 mpg (21.85 km/l).
So, this engine is DVVT DOHC 12valbe EFI engine.
Dynamic Variable Valve Timing is the name of Daihatsu and Toyota is named as VVT-i .
