Now why Suzuki is not thinking seriously about diesel is perplexing.India is its main market now and boy do Indians love diesel.
Maruti did have plans to launch the diesel version of the SX4 sometime this year[2008] possibly with a tweaked 1.3L multijet engine but given the demand for these engines in the other cars Maruti would just not be able to sell any diesel SX4's due to lack of availability of the engines and hence have now postponed the plans for the disel SX4.
This should come as a shot in the arm for rivals especially ones who have diesel options.As far as the waitng period for the swift dzire goes someone just told me book now and get delivery only in 2009.
