We are going to trade in our 06 plate golf and want something with a bigger boot. An estate seems like the obvious choice.
Looking online though they all seem to have 1.2 or 1.4 engines. My golf is 1.6 and not a fancy racer edition or anything. So why do these bigger cars, with capacity for a larger load have smaller engines?
Will I notice them being sluggish, or are newer engines more efficient at getting mph out of the car? 
Also can you recommend some?
I'm thinking golf/ Passat - lovely but ££
Skoda Octavia estate
Not sure what else TBH.
Thanks! :)
