2021 BMW X3 and X4 facelift includes torque boost for M Competition models
Updates part of wider facelift for SUV and coupé-SUV line-ups
The range-topping M Competition versions of the BMW X3 and X4 have gained a revised powertrain that offers extra torque as part of the mid-life facelift of the wider model range for the two SUVs.
BMW has made a series of changes to the wider X3 and X4 range, with design tweaks to both models that include a revamped larger kidney grille and new-look headlights. The facelifted version of both models will go on sale in the UK in September, with pricing starting at £43,370 for the X3 SUV and £49,010 for the more sweeping X4 coupe-SUV. Meanwhile, every engine in the standard X4 and X4 line-up is now electrified.
The X3 M Competition and X4 M Competition will also go on sale in September, priced from £85,100 and £86,860 respectively.
For the range-topping M Competition versoins, BMW has made tweaks to the in-line six-cylinder 3.0-litre twin-turbo petrol engine used by the Porsche Macan Turbo rivals, which were first launched in 2019. Although peak power remains at 503bhp, the addition of the lightweight crankshaft used for the M3 and M4 models and a revamped cylinder head core has allowed BMW to increase the torque by 37lb ft to 479lb ft, on tap from 2750rpm to 5500rpm.
Both machines can achieve the 0-62mph sprint in 3.8secs, with a top speed of 155mph. The X3 M Competition has a fuel economy of 25.7-26.1mpg and CO2 emissions of 241-251g/km; on the more swooping X4 M Competition those improve to 26.1-26.4mph and 238-248g/km respectively.
The X3 and X4 M Competition both retain an eight-speed torque-converter automatic gearbox, along with a rear-biased all-wheel drive system.
Adaptive M Sport suspension is standards on both models, with electronically controlled dampers used increase ride comfort by reducing wheel and body movements. That combines with the M Servotronic steering and Dynamic Stability Control (DSC), and BMW has added an M Dynamics Mode that allows for extra wheel slip to enable on-track drifting.
The performance models also feature 21in wheels and M compound brakes as standard. BMW claims new forged allows save 2kg of weight per wheel.
The M Competition models take styling cues from the updated versions of the standard X4 and X4 (see below), with the addition of M-specific styling elements. They use a one-piece frame version of the enlarged kidney grille, which features the frame finished in gloss black. It also features a built-in black bar that houses the front-facing camera. Adaptive LED headlights are standard, with BMW’s laser light system optional.
BMW has also added new bespoke M Competition side air intakes, which are framed with high-gloss black elements, and a revamped rear spoiler. That is part of a revised rear apron, which features a new design shaped like a ‘large anvil’ and twin black chrome exhaust pipes.
Inside, the sporting variants feature sports seats and the ‘control island’ used in the M3 and M4, along with BMW Live Cockpit Professional, which is based around two 12.3in digital displays. A Harman Kardon surround-sound system is also standard.
For the first time on the X3 and X4 M Competition models, BMW's Driving Assistant Professional system will be offered as an option, which included features such as Active Cruise Control and parking assist.
*X3 and X4 reveive styling overhaul, new equipment*
BMW has made design tweaks to the standard versions of the X4 and X4 models that include a revamped larger kidney grille and new-look headlights.
The tweaks are designed to give the third-generation X3 a more 'robust' SUV appearance. The kidney grill has been increased in size, with a new black bar to give it more visual separation. The headlights are flatter, with full LED as standard and BMW's Laser Light system available as an option.
The X3 gains a new front April, raised underbody protection and window graphics and roof rails finished in aluminium. The rear styling has been reworked with larger exhaust pipes and narrower rear lights.
The styling of the X4, which is 43mm longer than the X3 and sits 55mm lower, has been reworked to emphasise its more ‘sporty’ coupe-esque styling. That includes the revised grille, and a revamped rear engine design.
Both models will be offered in M Sport trim, which adds a mesh kidney grille with black gloss surrounds, along with extra gloss exterior trim and M Performance aerodynamic styling.
In the UK, 19in wheels will be standard, with the M Competition versions sitting on 21in alloys.
The interior styling has been revamped with a new centre console taken from the latest 4 Series, with a central display built around a 12.3in touchscreen. Enhanced sports seats are available, and M Sport models feature leather upholstery as standard.
The petrol and diesel line-up for both models has been revamped, with 48V mild-hybrid or plug-in hybrid on all powertrains.
Three diesel engines will be offered on both models: the 187bhp xDrive20d, 282bhp xDrive30d and 335bhp M40d.
The X3 will be offered with the petrol-engined 177bhp xDrive20i and the 249bhp xDrive30e plug-in hybrid, which can complete up to 31 miles of electric-only running.
Both the X3 and X4 also feature a 355bhp M40i model, which used in in-line six-cylinder engine and can achieve 0-62mph in 4.9 secs.
As standard the X3 and X4 use BMW's all-wheel-drive technology, which is rear-drive optimised in an effort to offer typical BMW handling.
Every powertrain uses an eight-speed automatic gearbox, with the M40i, M40d and all X4 models gaining a sport version that offers paddle shifts and launch control.
All M Sport-spec models gain variable sports steering and M Sport suspension, with adaptive suspension optional. The M40i and M40d feature a flap-controlled M Sport exhaust system, along with upgraded brakes.
