2018 BMW X3 vs Lexus RX350

What's the difference?

BMW's 'B58' six-cylinder engine is what's known in the trade as 'a cracker'. Three litres and a turbo's worth of silky smooth power, it delivers big dollops of torque with the kind of immediacy once reserved for much larger units.

It's already a perfect match for the M140i hatch, as well as the M240i coupe and convertible. And once you hit on a winning formula, why not spread the joy into the ever-growing world of SUVs?

Enter the X3 M40i, the first performance variant in BMW's compact SUV range, sitting just under $100k (before on-road costs) and aiming up at a quality field of similarly sized and specified performance versions like the Audi Q3, Jaguar F-Pace, Merc-AMG GLC, Porsche Macan, and Volvo XC60.

For those of us unlucky enough to remember the first Lexus RX to launch in Australia, the memories aren’t the fondest.

If you can’t remember it, just picture the stodgiest-looking SUV you can - make it so bland a mere picture of one could cure insomnia - dragging a glass-walled cube behind the rear wheels. 

All of which makes the current-generation RX so incredible. I mean, just look at it; those big rims, the 3D-effect grille, the outrageous lines and creases. It’s about as far removed from its snooze-worthy predecessors as it is possible to get.

Little wonder, then, it has emerged as the second-strongest performer in the Lexus line-up. And with the RX recently refreshed (and with a seven-seat RX L model added for the first time) its high time we took a closer look at the Japanese premium brand’s large SUV.
