2018 BMW X3 Specs & Changes: First-Ever 355-HP X3 M40i

Going strong since 2003, BMW's compact crossover gains big 2018 updates heading into its 3rd-generation. Oh, and a 355-hp M Performance model for the first time.

Shedding about 55 kg of weight, an updated cabin with added storage, more aggressive exterior styling, and the first-ever M Performance version with the M40i, BMW’s premium compact SUV enters 2018 as a new, redesigned third-generation model returning to its 2003 origins.

Here, we look closer at the small German hauler’s significant updates for 2018. And if you’re looking for a plug-in hybrid version, BMW added a PHEV version with X3 xDrive30e in 2020.

X3’s Styling Changes

While the new X3 footprint is virtually the same as the outgoing model, other significant changes have been introduced, including a wheelbase that’s 5 cm longer, a long bonnet, and an extremely short front overhang, resulting in a more balanced version of BMW’s popular mid-size SAV (Sport Activity Vehicle).

Up front, the 2018 X3 finds a new windshield in acoustic glass; the headlights and new, horizontal-styled fog lamps (versus the round ones) are LEDs. The kidney-snapped grill finds an active air flap control and in the grill below the license plate holder is the optional Driving Assistant Plus sensor, including the semi-autonomous driver assistance systems.

The rear styling is more sculpted: a single exhaust pipe replaces the dual round ones, and the X3 M430i now gets the sports exhaust system: an automatic tailgate, and optional LED rear lights in a new 3D look round things out. Overall, the 2018 X3 looks way more planted, balanced, and aggressively styled when compared to the 2017 model.

BMW X3 Interior Adds More Cargo Space for 2018

The cabin finds all the new technology you’d expect but also offers additional storage like the door pockets holding one-litre bottles and the larger storage area in the centre console. In the trunk, and new adaptive fastening system is a nice addition for stowing larger items, and the 40:20:40 split rear-seat backrests can fold down electronically by the press of a button; opening the rear cargo from 550L to an extendable 1600L when needed. Plus, extra storage is now in the underfloor compartment, including a luggage compartment cover.

Optional upgrades include a full-colour HUD, additional chrome treatments throughout, an ambient air package, ambient lighting including light carpet, and a three-zone auto climate control system. For infotainment duties, a 12.3-inch instrument cluster and a 10.2-inch touchscreen with gesture control are also optional.

The engines in the 2018 X3 extend on the outgoing version, so there is nothing new besides an improved eight-speed Steptronic transmission and the BMW xDrive intelligent all-wheel drive system. The engine lineup includes the xDrive20d with a four-cylinder diesel engine, the xDrive30d with a straight-six diesel unit, and the new power plant in the top-end BMW X3 M40i, as discussed below. Following the official release, an xDrive30i and 20i engine variants will also be available.

Perhaps the biggest news here is the arrival of the first-ever M Performance variant of the X3, dubbed the X3 M40i, powered by a new M Performance six-cylinder in-line engine that will propel the 355-hp M40i from 0-100km/h in 4.8-seconds, hitting a top speed of 250km/hr. The is 3.0L engine claims to remain fuel efficient (if that even matters to consumers stepping up to this performance version), burning just 8.2L of fuel per 100 km on average (or 34.4 mpg imp).

Up against the likes of the Mercedes-Benz GLC and Audi Q5, the next-generation X3 is slightly bigger than the outgoing model with updated interior styling and features. But the big news is the new and anticipated X3 M40i — the first-ever M Performance variant in the lineup. Powered by a 3.0L inline-six, the 2018 X3 M40i can put down an impressive 355 hp and 369 lb.ft of torque to handle the roads ahead.

And if you’re looking to hit the back trails, the X3 features 8-inches of ground clearance will handle the job; while Adaptive M Sport Suspension will take care of both comfy highway drives and twisty mountain passes paired to an 8-speed Steptronic Sport Auto transmission.

2018 X3 M40i and X3 xDrive30i Release Date and Prices
