In November 2011, a new line of 1.6 and 2.0-liter petrol engines debuted. There is an aluminum block for 4 cylinders with cast-iron liners and an open cooling jacket, an aluminum 16-valve cylinder head with hydraulic compensators, intake and exhaust de phases, an IHI AL0070 or IHI AL0071 turbine (depending on the engine version) with an air intercooler, direct injection system, oil pump variable capacity and timing chain drive. The 2.0-liter engines have a Lanchester balancer to reduce vibration.
