PSA make engines for most everybody now; yes even your beloved thumping v6 diesel ford tonka wagon... hangon, thats the same motor with the volvo stamp, no now its bmw, what? No? its also a Landrover??? ... now i'm just confused, you want me to believe its Peugeot or Citroen??? look now it says its Mazda...
So PSA make millions of diesel motors every year in small and large wrappers... if you want a lightweight high speed alloy block diesel for aircraft you use PSA turbo charged Citroen Berlingo common rail.... start and end discussion here.
