BMW's third generation X3 is a premium mid-sized SUV that's a larger, plusher and more powerfully efficient choice than its predecessor, stacking up impressively against prestigiously-badged alternatives from Audi, Mercedes, Jaguar and Volvo in this sector. Like its rivals, dynamically targeted almost exclusively towards on-road use, it's another example of just how car-like a model of this kind can be.
You might think that sandwiched between the X1 and the X5, the X3 wouldn't have to spread its talents too broadly, but such is the span of rivals of this size that this third generation X3 needs to cater for quite different customer expectations in the compact luxury SUV segment. If those expectations extend towards a dynamic driving experience, then the X3 comes well prepared. With ideal 50:50 weight distribution, a finely honed chassis and xDrive intelligent all-wheel-drive, linked to Dynamic Stability Control, this SUV proudly shows off the handling characteristics for which the Munich maker is renowned. To further improve dynamics, the car is now lighter and rear bias of BMW's xDrive all-wheel-drive system has been increased.
As for engines, well as before, most buyers will choose a diesel, probably the 190bhp 2.0-litre xDrive 20d variant. There's also a 265bhp straight-six xDrive30d diesel derivative. And a potent 326hp M40d variant. BMW thinks that petrol power will get more of a take-up this time round, so is offering an entry-level xDrive 20i version, plus there's a range-topping 360bhp X3 M40i variant to take on rivals like Audi's SQ5. As usual with the brand, there's an optional Dynamic Damper Control system, optional Variable sport steering and an optional sports braking set-up. BMW also boasts that a fording depth of 500 millimetres gives this SUV decent off road ability too. Across the range, 8-speed auto transmission is standard.
The exterior dimensions of this third generation X3 are largely unchanged, but its five-centimetre-longer wheelbase, long bonnet and short front overhang emphasise its 50:50 weight distribution between front and rear axle. At the front, the chunky three-dimensional kidney grille and LED fog lamps feature a hexagonal design for the first time on a BMW X model. Moving to the rear, the three-dimensional LED light clusters, downward-sloping roof spoiler and twin exhaust pipes further enhance the appearance.
The interior of the this X3 follows BMW tradition with a driver-focused and ergonomically designed cockpit. Hexagonal forms and precise, bevelled edges are a distinct design theme. The material quality and fit and finish are of a class above what you'd expect for a mid-range SAV, as you'd expect from a BMW, while it is also impressively functional, with more cabin stowage compared to its predecessor.
To further improve comfort in the rear compartment, the angle of the standard 40:20:40 split/folding rear seat backrests can be adjusted individually and through various stages thanks to the optional rear comfort seat. This feature also allows the backrests to be released remotely from the load compartment, which expands the standard load capacity of 550-litres to 1,600-litres.
This X3 has come of age in third generation guise. If it struggles to match the profitability of its predecessor, then that'll be because competition in the premium mid-sized SUV sector is so much tougher these days. This model is, after all, an immeasurable improvement over the MK2 version in every possible way. Even the best of this car's prestige rivals can't match this one's hugely impressive blend of handling and efficiency. It feels up-market, it rides impressively and, thank goodness, on-tarmac, it drives just as a BMW should.
All of which means that buyers in this sector who can afford the asking price should find that this X3 adds up very nicely indeed. Assuming that they don't prioritise off road ability of course: few will. A vehicle this good ought to speak for itself. Try one and we think you'll find that it does.Click here to find out more about our BMW X3 range
