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.
BMW was once a brand most known for its range of sporty sedans and coupes. In the last 15 years, though, things have literally changed the face of the Bavarian juggernaut.
If its X3 SUV range is anything to go by, things are set to change a lot more before the brand has settled into its new comfort zone of electrified SUVs.
You see, unlike most of its rivals, the X3 is now offered in petrol, diesel, plug-in hybrid, and as the fully-electric iX3. This allows BMW to hedge its bets over various drivetrains, but it’s also one of the first automakers to have such a comprehensive offering for a single model.
For this review we’re looking at the xDrive30e plug-in hybrid model to find out if BMW’s PHEV offering has what it takes to win some premium dollars from the likes of Volvo, Mercedes, and Lexus, all of which have added hybrid rivals with plugs in this space in recent years.
BMW has form when it comes to performance SUVs, in the shape of M versions of its larger X5 and X6 models. And it has expertly applied that experience here. The X3 M40i is properly quick and dynamically sharp, yet comfortable, refined, and most of all practical when it needs to be. The price tag is large for a compact SUV, but the M40i's quality, value and all-around ability justify it.
The X3 xDrive30e is a sporty SUV with fantastic ride quality and slick driving characteristics, although its specs seem a bit behind on the electrified front despite it being the most expensive PHEV of its peers.
This leaves it with an odd split personality of being particularly limited to tight city driving to make the most of its EV features, while its engaging nature beckons more to the open road than some of its rivals. A jack of two worlds perhaps, but a master of neither.
