However, Honda Australia has managed to switch sourcing of its best-selling Jazz hatchback to Japan - now selling as the Jazz Vibe special edition - and is getting set to follow suit with the Civic sedan when the new generation arrives next month, says GoAuto. The production switch of both cars was arranged in just three months.
Ultimately, Civic sedan production will revert to Thailand, along with production of the Jazz and Accord.
Honda Australia will also resume importing the current-model Accord from the Thai plant once it becomes available, ahead of the roll-out of the American-designed model in 2013.
Meanwhile, Honda Japan is preparing to wheel out a super-efficient and powerful new 1.6-litre diesel engine under its Earth Dreams banner at the Geneva Motor Show next month.
Destined for the new Civic, due in Europe later this year, the engine is one of nine new Earth Dreams engines - in both diesel and petrol forms - that the company says will make it number one in fuel economy within three years.
Honda promises less than 100g/km CO2 emissions from the new diesel, which is also good for 88kW of power and 300Nm of torque - superior to the 82kW and 270Nm of the similar-sized diesel of the Mini Cooper D, which achieves 99g/km CO2 emissions.
Honda Motor Europe says it will show a cutaway version of the latest turbo diesel, which it claims will be the lightest in its genre, delivering a "class-leading balance of fuel economy and performance".
