The Reno,Forenza, Optra, Optra 5 are based on the DAEWOO LACETTI & NUBIRA III ...... they have no relation to the Lanos or Aveo.
They have the same 2.0L engine as the older Daewoo Nubira but they are slightly smaller and have a slightly different chassis.
The Aveo is based upon the Daewoo Kalos
The Lanos is dead.... nothing new is based upon it.
The RENO/Optra 5 are half way between a Lanos and a Nubira size wise.... I would say my car is atleast 12" to 16" longer and quite a bit wider.
As a result it's also heavy like the USA/Canada Daewoo Nubira.
The Aveo has many similarities but it's not the same chassis.
