i think its ok as a car in its own right, can't see why they called it a delta though, it hasn't got any lines on it that are even slightly the same as the old delta.
The Delta is called the Delta for the same reason as the Golf is called the Golf.
Lancia have used the Greek alphabet for many years. They couldn't really call one of their cars the Alpha, but otherwise their models have been called Beta, Gamma, Delta, Ypsillon and Thesis. There was also an early model called the Theta. I'm not sure if Theta or Thesis is actually a Greek letter. Perhaps they all are. The first ever Lancia was actually called the Alfa. Maybe they didn't register the name which could be why Alfa Romeo were able to use it.
The Model T Ford, VW Beetle, VW Golf and Toyota Corrolla have two things in common. They are all massive selling cars and they all kept the same name for decades. The FIAT Tipo will never feature on the list of the World's top selling cars for more than one reason, but the major one is that they didn't sell it for long enough.
It would have been a lot easier if one of the 3 brands had been dropped because marketing them all must be a nightmare.
Personally I can't wait for Lancia to return and I would definitely buy one. One oddity about Lancia is that since their withdrawl from right hand drive markets, a number of their models have, instead of pictograms on the minor controls, have had the functions written in English!?
