Yep definately 18d probably 150hp or 160 hp and emissions bellow 100g per km. The idea of that wide range of engines in Europe is that the laws in the countries are very different and the taxes for example in the scandinavian countries are killing!!! Everybody wants a 306hp 35diesel, but when it comes to taxes...things get ugly and in some countries very ugly!!! In normal city driving the fuel consumption difference between 20d and 35d would be in the range of 1-2 litres (quart to half a US Gallon), but the taxes and the price returns everybody to earth here on the continent. Great compromise is 30d and the 23d would superb too. Lets just see what will be the prices here and is going to make it to the states
