Though an SUV, the 2020 X3 M Competition’s chassis is tuned for the utmost track experience. (BMW)

What we’re driving: 2020 BMW X3 M Competition

BMW’s max-performance compact SUV provides stunning thrust, but with a severe ride-quality penalty.

The concept of the high-performance SUV (more appropriately, “crossover”) can be difficult to reconcile. I understand that everyone currently wants an SUV body style and performance brands have to answer that demand or else it’s a sale potentially lost. But the notion of SUVs or crossovers that are “tuned” for performance is perplexing because SUVs and crossovers exist because of their supposed utility and/or off-road capability. That usually implies long-travel suspension and heightened ground clearance – chassis aspects typically at odds with hot racetrack lap times.

In no vehicle I’ve driven has the performance-SUV dichotomy been more butt-blisteringly obvious than BMW’s X3 M Competition. Its stupendous accelerative performance comes with the most abysmal ride quality I can recall. Driving on the “Comfort” setting of the fancy Adaptive M Suspension electronically controlled dampers, the ride is so relentlessly brittle I thought perhaps the adjustment was malfunctioning.

But ratcheting up to the Sport and Sport + settings, did, astoundingly, find a way to make the ride harsher yet. Accelerating moderately over a low, rolled curb while tightening the steering angle produced a suspension response so violent it jerked the wheel from my hands. I don’t know how much suspension travel the adaptive dampers and the M’s revised suspension pieces deliver, but it feels like zero. If you don’t relish constant head toss from your $80,000 compact crossover, the X3 M Competition ain’t the choice for you.

But if you want the maximum expression of the company’s still-wondrous turbocharged inline six-cylinder, then this is place. The most-powerful-ever iteration of the turbocharged S58 3.0-L I-6 is magnificent: tuned to a 503-hp, 442 lb-ft (599-Nm) fare-thee-well yet revving to 7300 rpm, it’s V8 muscle and Mad Max-perfect exhaust menace all slathered over with that renowned inline-six butter.

It’s hard to imagine what BMW could do to make this engine more satisfying or more expressive (apart from upping the 14 mpg city/19 highway rating). A more appropriate transmission to support it would be BMW’s dual-clutch automated manual rather than the adequate but surprisingly slurry 8-speed torque-converter automatic. The dual-clutch handles X3 M Competition-type torque in other M models.

The X3 M’s interior is beautifully executed and trimmed, with the 14-way adjustable M sport seats being a particular treat. The digital instrumentation is a little cold for a performance machine, but everything is assembled so tightly and robustly – all X3s are built in BMW’s Spartanburg, SC, assembly plant – the cabin somehow feels as if it will survive the lifetime pounding the suspension is designed to inflict.
