Matthew – I wondered the same as you, I wanted to know if it felt ‘quick enough’ when overtaking. Mat Watson from Carwow does a good review on YouTube if you want to watch it. I’m not sure how to put the link here so if you search it, it’s called: This new XC40 is the BEST Volvo! *Review*.
He compares it to a standard XC40 T5 and does a drag race and rolling start. It gave me the confidence that it’s more than capable when pulling onto motorway etc.
