It is well known that Maruti is being crippled increasingly by its workers striking work at the Manesar plant and this has been pushing up the waiting period for its cars to many months.  Tata Motors which has the Fiat Multijet engine in its range in the form of the Quadrajet just as Maruti does (the same engine which Maruti calls DDiS) is trying to take advantage of the demand for diesel engined cars and Maruti’s inability to meet demand, by increasing the production of its own vehicles.  Tata has the very capable Manza and now the facelifted Vista to take on the Dzire and the Swift from Maruti.
