My judgement is based on following grounds:

Volkswagen Polo: apart from the DSG gearbox, innovations are c1early rare at this level of the range, but the overall package in terms of quality, finish and road behavior is exceptional. Volkswagen's selling price is competitive.

Toyota iQ: unlike the Polo, this car is packed with innovations. However, the car, while featuring innovative technology, needs to progress in terms of finish (improvements planned for 2010) to be able to c1aim the top slot.

0pel Astra: a pity the concept led to an excessive increase in the car' s overall size without any significant gain in cabin space, while the current trend is for less heavy cars. Excellent dynamic performance, good design.

Ex-Peugeot 3008: the surprise of the year in terms of dynamic performance. A selfish car which is a little too focused on the driver (instrument panel). Clumsy design. 

Citroën C3 Picasso: a marvellous way of utilizing an existing platform. Good design, ample cabin space but an expensive package overall.

Ex-Skoda Yeti: Good use of existing sub-assemblies. Good finish given the competitive selling price. A great... UFO.

Mercedes E-class: Its key quality is that it's a worthy descendant of the previous generation. Is that enough? A step change in terms of desing.
