Business or private user, the main consideration to make when choosing between the 1.5 and 2.2 diesels is the trade-off in efficiency vs performance. Are the newcomer’s economy savings enough to warrant the latter’s drop-off, or are 0-60mph times, cruising refinement and top-end numbers more important? And don’t forget those low-emission family hatch rivals either, the classy Golf Bluemotion and great-value Octavia 1.6 TDI Greenline. But if it’s a Mazda you want, plenty of drivers will be more than happy with this decent, all-round capable 1.5D.
