Yes Chevrolets next Optra is being tested and is going to replace the current model which was launched in 2003. The new Optra or Nubira looks a bit like the Civic from behind and Corolla from the front. Not a bad thing. However what is important is how good is the engine and gearbox, something which was never the strong point of this Chevy.
The 2.0 TCDi engine which does duty in the current Optra diesel and Captiva will be used in the new Optra as well. But GMDAT(General Motors Daewoo Auto Technology) need a good petrol engine which has good mileage and doesnot feel strained at higher revvs. This new Optra should take the fight to the Civic and Corolla as its going to be priced well with good standard equipment and features.
