SINGAPORE

Sportier, more modern, and more digital. That’s what BMW is promising with the midlife refresh of its X3 SUV and X4 SUV-coupe.

The third-gen X3 SUV and its sibling, the sleeker X4, are set to be officially launched in the metal at this year’s Chengdu Motor Show in China on 27th August, and then make its European premiere at the IAA in Munich, Germany, on 7th September.

There will be three petrol engined versions of both cars, plus an X3 plug-in hybrid. Separately listed are the also-updated X3 M Competition and X4 M Competition (see below)

Along with the usual visual tweaks, all the petrol versions of the cars will come equipped with 48-volt mild hybrid systems for better efficiency, and eight-speed automatic transmissions.

Immediately apparent from images is that the front bumper, intake grille, and headlights of both models have been given a new look. The tail lights also feature a new design motif. 


We tested the plug-in hybrid version of the BMW X3 against the regular gasoline model – and the numbers really were quite impressive.

While the X4 does feature the same nose as the X3, it adds an exclusive distinguishing feature in the form of the mesh kidney grille, already familiar from other sporty BMW models. The X4 also has flat full LED rear lights that are designed to emphasise the vehicle width.

The X3 and X4’s in-car technology has also been given a big update, and they will have BMW’s Driving Assistant Professional, available for the first time as an option. These systems deliver a lot of active safety aids and functions that are useful for urban driving safety, including active cruise control and city brake function. Another new feature is the optional BMW Drive Recorder, which can take videos around the vehicle.

The cars’ dashboard architecture is shared with the current BMW 4 Series. BMW’s Operating System 7 holds court in the cabin, which means that it will have free, downloadable over-the-air updates to keep the system up to date for the foreseeable future.

The range starts from the X3 and X4 xDrive20i, with a 184 horsepower, 2.0-litre turbo engine. Fuel economy is rated at 8.4l/100km.

Next up is the X3 and X4 xDrive30i, with the 2.0-litre turbo engine up-rated to 245 horsepower. They are only marginally thirstier, with a fuel economy figure of 8.5l/100km.

Further up the line, sitting just a notch below the massively powerful X3 M Competition and X4 M Competition, are the X3 and X4 M40i. Both are powered by the same inline-6 cylinder, 3.0-litre turbo engine with 360 horsepower and claim an official fuel economy of 9.5l/100km. 



The X3 gets an extra variant in the form of the X3 xDrive30e. The new car will be an update of the current-generation plug-in hybrid, which features a full petrol-electric hybrid drive system with a 2.0-litre turbo engine. It can operate as a full electric vehicle for up to 50km, or be driven as a standard hybrid vehicle. 

The X3 and X4 are essentially mechanical twins with different shaped bodies, so much that their performance figures and fuel economy figures are identical. Also of interest is that unlike other more affordable SUVs, the X3 and X4 feature active four-wheel drive across the entire range, which is what the ‘xDrive’ in the model names represent.

The updates carry across the board, which means that the high performance versions of the X3 and X4 get new clothes too. Not just that, the engines have also been fettled to pull even harder. 



Peak power from the 3.0-litre, inline-6 cylinder turbo engine remains unchanged with 510 horsepower, but torque has been increased by 50Nm to 650Nm, partially through the used of a lightweight crankshaft taken from the new BMW M3 and M4. The net effect is that the 0 to 100km/h sprint time of the X3 M and X4 M have been shortened by 0.3 seconds, to a supercar-like time of just 3.8 seconds.

The new control island from the current BMW M3 and M4 models has also been ported over to the X3 M and X4 M. The centre console now includes two new buttons in addition to the specific M gear selector with Drivelogic rocker switch, the BMW Controller and the red engine start button. Two individually configured variants of the M set-up can be permanently stored and retrieved at any time using the two M buttons on the steering wheel. 



Based on the current range available at Singapore’s BMW dealerships Performance Motors and Performance Munich Auto, we can expect both the xDrive30i and xDrive40i variants, along with the X3 xDrive 30e and M versions to all be available in Singapore once again. Prices are not yet available, but the word is that the new models will arrive in Singapore in the final quarter of 2021. As it is with the vagaries of the local COE system, current X3 and X4 prices can be used as a rough gauge but we will know more in a couple of months.
