Mazda seem to have introduced a 2.2 range of engines. Nothing on mazda.ie so I emailed them a few days ago just to get a response today.
I am copy pasting their response here FYI. I think it is a great car and I will definitively consider upgrading to it soon.
Thank you for your enquiry with regards the Mazda6. The new 2.2l diesel engine will be available in three power outputs the 125ps, 163ps and 185ps. Two of these power outputs (163ps and 185ps) are now available via our dealer network with prices starting from €31,145 for the Mazda6 2.2 (163PS) 4dr Sport model. The 125ps will be introduced later in the year and will be a direct replacement for the 2.0l 140ps engine currently available (pricing and performance will be almost identical).”
