Not just has the power output increased, there is a substantial spike in the fuel efficiency as well. From an earlier ARAI certified figure of 17.9 kmpl, the fuel efficiency for the petrol Swift has jumped up to 20kmpl. Thanks to the new weight reduction techniques adopted by Maruti Suzuki, which also includes incorporation of advanced plastic fuel tanks, the fuel efficiency of the diesel engine too has gone up. The ARAI figures for Swift 1.3 DDiS diesel is 23.8kmpl, and increment of 2.8kmpl over the efficiency of the earlier version.
The engines for the new Swift will come mated with a five speed manual transmission. A much needed 4 speed auto variant will also be introduced a year down the line.
