2012 Mazda CX-5 at Frankfurt

2012 Mazda CX-5 - Frankfurt Debut Mazda has been touting its SKYACTIV Technologies for some time now, and the new 2012 Mazda CX-5 – which Mazda will debut at Frankfurt next month – is the first Mazda to come endowed with a complete raft of SKYACTIV stuff. The clever stuff includes Mazda’s new modular platform that can be used for everything from the Mazda3 upwards, and which is said to give the CX-5 not just car-like handling but proper sporty and stable driving dynamics too. The SKYACTIV technology comes in to play with the engines too on the CX-5, with the new 2.2 litre diesel delivering 173bhp and a remarkably low 120g/km in standard guise.
