Proposition: if you're a European car maker, your ability to make a successful model within different categories is determined by the alcoholic drinking habits of your native country.

So if you are based in a country which makes more wine than beer - stick to small cars - your attempts at big cars (whether saloons, SUVs, MPVs etc) will fail, so France, Italy, Spain etc are doomed, although your small cars will be successful.

However if your country prefers beer, you can build successful big cars alongside small ones - think UK, Germany, Sweden, Czech.

Does this work outside Europe??
