Mazda is currently enjoying a series of successes that's envied by almost every other car company in Australia, with a number of its models striking a real chord with Aussies.

From the Mazda3 and CX-3 through to the CX-9 and BT-50, the Japanese company really can do little wrong in the eyes of its customers.

One of its biggest hits of recent years has been the mid-size CX-5 SUV – in fact, the company says it's the one of its most successful product launches of all time, and became the pioneer for a new look and a new technical direction for the company.

The CX-5 has been the number one selling SUV in Australia for the last four years, which puts the company in an interesting position. How far can it go in fixing something that's demonstrably not broken, especially for its pool of 115,000 CX-5 owners?
