I would wait until the technology is thoroughly proven before I put my money on the counter for an EcoBoost engine. Lower tech vehicles markedly reduce exposure to expensive repairs and replacements.
Spinning at over 170,000 rpm turbos generate 2,000 ºC temperatures that can cook engine oil and produce harmful sludge. Turbos don't age well. The high operating pressure severely stresses internal engine components prejudicing long-term reliability. Expensive engine repairs are often required around 120,000 kilometers, just after some powertrain warranties expire.
Gasoline direct injection (GDI) is also producing severe teething problems including high pressure fuel pump failures, gasoline diluted oil, carbon build up on intake valves and excessive noise.
Better to choose a vehicle with a larger non-turbo/GDI engine if you need more power.
