Petrol engines blend power with economy

Now fitted with upgraded electronics and low-friction components, Kia's revised 2.0-litre 'Theta II' petrol engine delivers more power, improved durability, enhanced refinement and reduced fuel consumption and emissions.

This four-cylinder 1998 cc powerunit has dual CVVT (continuously variable valve timing) for both the intake and exhaust valves, four valves per cylinder and features weight-saving, all-aluminium construction with a cast aluminium block, cylinder head and sump. Fitted in new Sportage, maximum power is 163 ps, with 194 Nm of peak torque at a modest 4600 rpm.

Later this year, new Kia Sportage buyers whose priority is fuel-economy, will be able to order Kia's 1.6-litre Gamma petrol engine fitted with GDI (petrol direct injection) technology. Producing a highly competitive 140 ps, the arrival of this engine marks the first appearance of GDI technology in a Kia vehicle.

GDI lowers emissions while raising power and torque outputs and improving fuel economy. The typical range of benefits include delivering 7% more torque at low revolutions, 12% more torque at high revs and 10% better fuel economy overall - compared to a conventional engine of a similar capacity.
