BMW’s X3 and X4 are quite clearly siblings, the latter obviously being the naughtier of the two.
Yet although they share the same face, the latest generation of these crossovers have been differentiated more than they were in their previous guises, even in the way they drive.
We recently test drove the X4 20i and X3 30d back-to-back and it made for some interesting comparisons, so we decided to do the obvious and square them off in a single review.
Design and packaging
Although the pair share a common 2864mm wheelbase and 204mm ground clearance, the X4 (below) has a sportier stance, its body being 44mm longer, 55mm lower and 27mm wider than the X3's.
Whereas the X4’s dimensions prioritise racy looks and road holding, bearing in mind that its centre of gravity is still too high to qualify as a truly dynamic machine, the X3 is shaped more around practicality.
That’s not to say that the X4 is necessarily cramped or impractical. As with the X3, rear passengers have plenty of leg-stretching space, but that sloping roofline - nice as it is to look at - restricts headroom in the X4 and anyone even slightly taller than average will find themselves feeling pretty claustrophobic back there.
The X3 (below) solves that problem and also has a more useable boot. Although the X4’s luggage compartment is somewhat larger in terms of surface area, and only slightly smaller in terms of outright luggage volume (525 litres versus 550 in the X3), it’s shallow like a sedan’s boot and you can’t load it up to the roof as you can in the X3.
Engines and performance
BMW has taken a ‘top and tail’ approach to the X4’s engine line-up as it has found that South African buyers tend to prefer either the cheapest option or the baas-vannie-plaas performance version.
Hence the X4 is available in two ‘base level’ 2-litre turbocharged four-cylinder variants, namely the 135kW/290Nm 20i petrol and 140kW/400Nm 20d diesel, and there’s a thunderous M40i 3-litre turbo six on offer with 265kW and 500Nm, while the M40d is on course for early next year.
The X3 range comprises all the aforementioned plus two midrange variants in the form of the higher-output four-cylinder 30i petrol (185kW/350Nm) and 30d six-cylinder diesel (195kW/620Nm).
We’ve driven all but the 30i in the course of the last year, and it’s the 20d that hits the sweet spot for those seeking something at the more sensible end of the price spectrum. It doesn’t necessarily feel fast, but it’s got enough grunt for the average driver and the best economy in the range. At R711 369 for the X3 and R846 542 in X4 guise, it’s priced within a few thousand rand of the equivalent 20i xDrive (all-wheel-drive) petrol models in both cases. The X3 20i is still the cheapest option however if you’re going for the ‘sDrive’ rear-wheel-drive option, at R661 199.
The X4 xDrive20i that we were exposed to recently offers acceptable performance and it’s not laggy off the mark, but it does lack responsiveness once on the boil. It also consumed almost 12 l/100km in town. There’s really no good reason to take this over the diesel.
But it gets even better. The X3 xDrive30d has a gem of an engine, with its silky-smooth power delivery and slightly throaty straight-six soundtrack - we actually wished for an adjustable exhaust flap just to crank up the volume a bit. Economy proved acceptable for its engine size, the 30d drinking 9.6 l/100km in urban confines. It’s a lovable package for sure, but comparatively pricey at R901 213.
The range-topping M40i models - R1 038 126 in X3 guise and R1 144 185 as an X4 - offer sports car like performance that is downright exciting, and the M40d doesn’t trail too far in that regard - all of course, at a price.
All engines are mated to a smooth-shifting eight-speed automatic gearbox.
Although the X3 and X4 share their basic underpinnings, the X4 has a firmer suspension set-up and more rearward-biased torque distribution and as a result it is generally more fun to drive, but the downside is that the ride feels a bit too firm for South African roads.
The X3 is also set-up a little on the firm side, but it’s reasonably comfortable nonetheless and ultimately offers the better balance between ride and handling.
The steering on both is precise and nicely weighted, imparting a sturdy and confidence-inspiring feel.
Interior and gadgets
Although they don’t have BMW’s new-generation operating system with its futuristic graphics, as seen on the soon-to-be-launched X5, the X3 and X4 still feel fairly modern and classy inside, and there’s no faulting the materials used, for visual and tactile quality at least.
You can spec them to the hilt with electronics and gadgets, to the detriment of your budget, and the optional Navigation System Professional infotainment system with its tile-style layout still feels crisp and modern.
Some of the fancier options include gesture control, a comprehensive heads-up display, digital instrumentation, multi-colour mood lighting and BMW’s ‘Driving Assist Plus’ package that allows semi-autonomous driving in certain instances, complete with steering assistance.
As for standard amenities, all X3s and X4s do come with three-zone climate control, automatic tailgate, iDrive with navigation (Business) and synthetic leather seats.
There’s no denying that BMW offers a broad and enticing range of crossovers in the middle segment, but if you’re looking for a winner here the smart money is on the X3. Not only is it locally made, so you’re supporting the economy by buying it, but it’s over R100 000 cheaper, as well as more practical and comfortable on the road.
But if you’re swayed by the X4’s more athletic design and dynamic qualities, and money isn’t too much of an issue, you will have more fun in an X4 and enjoy more distinction out on the road.
A standard BMW X4 xDrive 20d M Sport starts at R891 442 before options. It is sold with a 2yr/unlimited km warranty and a 5yr/100 00 km maintenance plan.
In terms of dynamic abilities, the BMW X4 is right up there in terms of handling and body control. The speed with which it settles after a quick change of direction is impressive and BMW's xDrive system provides an abundance of grip. The turbodiesel engine and gearbox are a perfect marriage of performance, economy and refinement. It's pretty hard to think of an offering out there that delivers everything as well as this X4.
With a coupe roofline, there's bound to be a loss of practicality and it's up to the buyer to decide whether the compromise is worthwhile. In effect, you pay BMW an extra R130 000 to take some of your packing space away. That price, R891 442 before ticking boxes beyond M Sport seems a little high, because you're getting mighty close to something like a VW Touareg. Alternatively, you save money and opt for a Volvo XC60 instead.
Here’s how much the new BMW X4 M40d will cost you in SA
Back in February 2018 when BMW whipped the covers off its second-generation X4, one of the most interesting snippets of information was the introduction of the new M40d derivative. And while this diesel-powered M Performance variant was not part of the range at the local launch, we now have pricing ahead of its arrival in South Africa in the first quarter of 2019.
The X4 M40d will start at R1 165 863, making it some R21 678 more expensive than its petrol-powered sibling, the M40i.
While the M40d – which we drove at the international launch in South Carolina – ships standard on 20-inch alloys, 21-inch items can be optionally specified. Other interesting extras include an electrically operated tow hitch (R11 500), a panoramic sunroof (R21 100), Adaptive M Suspension (R10 300) and a head-up display (R17 000).
As a reminder, the M40d draws 240 kW and 680 N.m from its straight-six turbodiesel heart, completing the obligatory dash to three figures in a claimed 4,9 seconds (one-tenth behind the M40i derivative).
It employs an eight-speed Steptronic transmission (with shift paddles) and xDrive all-wheel drive as standard, as well as M Sport brakes and an M Sport differential.
Tuner hands new (diesel-powered) BMW X4 performance upgrade
AC Schnitzer has revealed its performance upgrades for the new BMW X4, handing two of the Bavarian automaker’s diesel powertrains extra power and dollops of torque.
The oil-burners in question are the Munich-based brand’s 3,0-litre six-cylinder in M30d and M40d states of tune. The aforementioned engine, which produces 195 kW and 620 N.m of torque as standard, has been uprated to deliver 232 kW and 705 N.m to all four corners via BMW’s xDrive system. The M40d, meanwhile now produces a whopping 279 kW and 780 N.m of torque (up from 240 kW and 680 N.m).
Although the power output falls short of that produced by BMW’s recently unveiled high-performance X4 M (353 kW and 600 N.m) and Competition (375 kW and 600 N.m) models, you may have noticed that torque is significantly more. The Aachon-based firm believes “increasing torque is more important”.
To fully utilise this performance (especially when cornering), the German tuner has equipped the G02-generation X4 with a suspension kit, which can lower the car by up to 25 mm.
The coupé-styled SUV has also received some aerodynamic updates, such as a carbon-fibre “Racing” rear spoiler (a revised roof-mounted item is also fitted) and an extended front splitter.
The interior has received a dash of aluminium, with the pedals and iDrive controller finished in this material.
The performance-infused BMW X3 M and X4 M are expected to in South Africa later this year and although we will be driving both in the United States this week, BMW has revealed the X3 M and X4 M with performance parts, take a look…
While we wait in anticipation for our very own Ciro De Siena to return from the US with a report on the X3 M and X4 M, this is what they will look like dressed-up in M Performance bits.
Carbon fibre is extensively used to complete the look with features such as a carbon fibre radiator grille, carbon fibre intakes and door sill finishers with carbon fibre inserts and an M Performance overprint. The roof edge spoiler is finished in gloss black, the same finish for the rear fins on the X4 M. The M Performance decals add colour and exclusivity to the overall package. LED door projectors with M Performance motifs add a special touch at night.
BMW X3 M and X4 M get M Performance Parts treatment
BMW is now opening its M Performance Parts catalogue to the X3 M and X4 M, allowing owners to give a more distinctive design edge to their high performance crossovers.
As it goes with these packages, there are no performance mods here, but remember that the X3 M and X4 M are already fitted with the M Division’s most powerful six-cylinder engine yet, good for 353kW in the standard models and 375kW in the Competition derivatives, with 600Nm on command in both cases. According to BMW, the respective versions get from 0-100k/h in 4.2 and 4.1 seconds.
What the Performance Parts offer is a more distinct style through a range of exterior components that are hand-crafted from carbon fibre, and then given a high-gloss polish.
Buyers can opt for a grille surround, air breathers and door sill finishers, all in carbon fibre, as well as M lettering on the front, side and rear of the car. Also available are a rear spoiler for the X3 M and rear fins for the X4 M, both finished in high-gloss black.
