First of all, congrats on the very informative and organzied post. :)
Now, on the cars:
Porsche 918 Spyder - Loving it. For the first time Porsche has done something that drastic in their design. Although it's a concept, I hope it will come out like this. Just not with those rims, pl0x.
Peugeot SR1 Concept - carbon + alluminium + that design = awesome! Just give me a petrol engine in it and I'll be very happy.
Mansory Bullcrap Ghost - just no!
Lotus Elise - loooks too much like an Evora. I miss that round tricky look it had.
Citroen DS3 Racing - not a fan of those coloured roofs. But other than that looks pretty awesome. Very powerful for a Citroen as well.
Audi A1 - from the door back, it reminds me of the Fiat 500. The front is yet another A series, I'm sorry but having so much models with the same front is just a no-no. '
Merc F800 Concept - yet another "nature friend". Why would you get a Merc, pretending to be eco-friendly, when it can only do 18 miles? Who buys such things?
Ferrari 599 HY-KERS - this one is nice but Ferrari, don't show-off too much, we all know that your cars make a lot of CO2, so this one is a bit late, eh?
VW Touareg - the new fancy front, God, why putting it on all the models? Though I admit they've done a good job on this one, technically and visually.
Citroen SurVolt Concept - I love when Citro's designers go beserk, remember the GTbyCitroen? Do want one in my imaginary garage.
Porky Cayenne - have you seen the rear of that thing? Looks so Renault Koleos-ish. I'm sorry, I know it was an ugly car and proably still is but don't put such cheap parts on it.
Lexys CT200h - looks promising but after they've showed us they can do great cars (such as the IS-F and the LF-A), I just can't help thinking that they are just doing those hybrids for publicity.
Alfa something - looks awful. The 8C took a lot of time to get used to but this one...sorry, no!
Porsche 911 GT3R Hybrid - hybrid - yes, a smart and interesting one - yes. Good job, the first Porsche hybrid that attracted my attention.
Carbon Fiber Egg - ah well, you just get used to seeing a new Veyron every time. Give me a ZOnda F Roadser, please.
Zonda Tricolore - yay! Yet another piece of art from Pagani
Audi RS5 - looks great. Should drive great. In a test by Auto Motor und Sport, the S5 beat the M3. So imagine what this will do to the cocky M fella. :D
Lambo LP570-4 SL - everything good about it has already been said. One of the greatest Gallardos ever made.
Phew, and there are more new. Don't forget the Agera, Mikey. :p
