First thing I think when looking at a Falcon is yes, i'll take the 4 cylinder option. Worked so well in the Commodore years ago. Why Ford hadn't thought about doing it earlier is beyond me.
 
If anyone is truly considering buying a Falcon, wait six months and buy it at the end of the year. They pretty much give them away, especially ones that have been registered by the dealer. A dying model presents excellent value for money.

Every review I have read has praised the Ecoboost Falcon.  Losing 60kg over the front axle apparently transforms the steering, and the thing can lay down really respectable acceleration times (0-100k in 6.7s and 400m in 14.5s from memory).  I personally don't think it is the size and performance of the engine that is an issue, especially with 350Nm of torque available at a lazy 2000rpm; more that people are generally buying smaller cars to begin with.
