The Suzuki won't be as efficient.
The most fuel efficient gasoline engines, pound-for-pound, out there are the engines in the Jazz/City and the Vios/Yaris. Even without the CVT, the Toyotas get good numbers... but the Honda CVT is a definite advantage in traffic.
Of course, since the Picanto and Getz have 1.1 liter engines available, despite the lag in engine technology versus the Japanese, the smaller size pays dividends at the gas pump.
But the overall, most fuel efficient AT on the road? A scooter. Buy one and you have enough change left over versus a car to build yourself a nice new TV room with a 60" LCD, 5.1 surround, Laz-E-Boy seats and a popcorn dispenser.
