Maruti Suzuki is on a engine upgrade spree and lined up is the diesel variant of the Maruti SX4 by August. The SX4 could be powered by 1.3 litre or 1.6-litre DDIS engine. However the obesity of the SX4 will make the latter engine more favourable. Fiat is also planning to offer a more powerful 1.6 litre multijet diesel powerplant in the Linea in the next few months. We have to wait and watch which engine Maruti chooses. We think it will be the 1.3 litre with VGT.
