The Liana won't give you much acceleration either, mainly for two reasons:
The gearing is taller, for more fuel efficiency around town so the pick is less. Secondly, it is a heavy car to pull around for a 1.3.
Out of the two, I feel the Liana is a better package. Nice interior materials, and nice color scheme on dash, doors, etc. Good seats, nice deck, nice gauges, powerful AC, awesome FF CNG kit, Good ride and suspension, and ABS available on some models. Boot size is good too, and very good pricing.
Plus the sport version has a nice body kit and 15inch wheels with low profile bridgestones and the ABS brakes that I just spoke of.
