It took decades to catch on, but Range Rover eventually inspired German carmakers to look outside big sedans to satisfy luxury car buyers. When BMW introduced its first SAV - Sports Activity Vehicle - the X5, the outrage was palpable. Nearly two decades later, the X5 is as indispensable to the BMW oeuvre as the 3 series.

The X5's sales statistics have been impressive, with 55,000 sold in Australia since 2001, and each generation outselling the previous one.

The fourth-generation X5 has arrived in Australia, with two diesels now and a petrol arriving early in 2019 before four-cylinder, plug-in hybrid and the head-butting X5 M arrive over the next year or two.

The G05 X5 is bigger, better-looking and loaded with new technology.
