BMW X5 4.8i Steptronic (2007) Driving Impression
Question the merits of the existence of the performance SUV as much as you want, they’re big business – both in the strictest sense (making money) and as image builders that through shared DNA raise the desirability levels of lesser models.
In both instances BMW has done well with the original X5, creating a niche within the SUV segment for a series of macho performance- and road-oriented vehicles that have become smash-hit sales successes, and also allowing for the emergence of a little brother, the X3. Who knows what will follow next!
But right now, the spotlight is on the second-generation X5, a vehicle that has to defend BMW’s honour against a whole raft of newcomers from the likes of Porsche, Audi and Volvo. Tested here is the most powerful variant, the 4,8i.
Presence by the bucket load
Being more than 50 mm wider than the original, as well as a significant near-200 mm longer, the new X5 casts a significantly larger shadow. And with mammoth 19-inch alloy wheels filling flared wheel arches, and plenty of “power bulges” to be seen in the design, especially on the bonnet, the X5 broadcasts its powerful intentions with zero restraint. Yet, at the same time, the design is also far neater than before, with beautifully balanced proportions and a particularly neat rear-end.
The extra length has been used to accommodate a third row of seats to combat the likes of Volvo and Audi. As with most such premium seven-seaters, the rearmost pews are optional, and in the BMW’s case cost R13 900. While it is true that seven seats are occasionally useful, most owners are likely to keep them folded down most of the time, in which case the extra length results in a truly massive boot, swallowing 620-litres worth of luggage! It helps, of course, that there’s no spare wheel to accommodate – in typical modern-day BMW fashion the X5 uses RunFlat tyres. Spare wheels are, however, offered as options on five-seater variants.
As for the rest of the cabin, BMW has managed to not only improve the perceived quality, but also the comfort levels. The second row of seats is split 60:40 and can fold/recline and slide individually. By sliding the seats forward, legroom for those in the third row can be improved. That said, those two extra rear seats are really not very comfortable and are only suitable for children and for shorter distances.
In front there’s preciously little to complain about. The layout follows the modern BMW norm, with a very simple, almost minimalistic instrumentation panel, neatly grouped audio and ventilation system interfaces and a colour screen to access a mind-boggling number of control sub menus. BMW’s iDrive has been refined significantly since the first generation made its debut at the dawn of the new millennium, and now offers far more logical menu structures. The standard specification of this model is comprehensive to say the least, and includes climate control, xenon headlamps, cruise control, a premium sound system, six airbags etc. And yet the options list is rather vast, allowing customers to effectively personalise their X5.
Lots of grunt
This X5 is powered by BMW’s high-tech 4.8-litre V8 petrol engine that delivers a whopping 261 kW and 475 Nm of torque. It makes use of a six-speed automatic transmission to send power to all four wheels via BMW’s xDrive permanent all-wheel drive system. xDrive was really developed more for extra security and grip in slippery conditions, rather than off-road ability, and the X5 offers no diff-locks and low-range transfer ‘box.
What it does offer, however, is frankly stupendous performance! Weighing in at over 2.2 tonnes, this X5’s sprinting ability will surprise many a lightweight sports car. The 0-100 km/h dash is completed in 6.5 seconds, accompanied by a lovely roar from the exhausts. The overtaking acceleration is excellent, too. There is a penalty, of course, and it is in the form of very high fuel consumption. The figure of 12.5 litres/100 km will take some light-footed driving to match.
Agility of a sports car
BMW’s chassis engineers need to stand up for a round of applause. That a vehicle of this size and weight can corner with the poise, precision and agility that it does is an enormous achievement, and very nearly matches the best that is out there (Porsche’s Cayenne). Even the “basic” X5s handle brilliantly, but when specified with the optional Adaptive Drive system (more than R30 000 extra), the X5’s body control is really stupendous.
Amazingly, the ride has not been badly compromised in the pursuit of its dynamic edge. Sure, at low speed the stiff sidewalls of the RunFlat tyres can be felt over poor surfaces, but as speeds rise, the ride becomes more absorbent and relaxing. A slight negative remains the low-speed steering, which is simply too heavy.
Verdict
Although the BMW X5 4.8i Steptronic is not cheap, it is nevertheless nearly R100 000 cheaper than a Porsche Cayenne and runs it very close for performance and agility. It also offers the option of seven seats, which the Cayenne can’t. Does that make the BMW the new champion? In many respects, yes, but it can’t yet match the Porsche for badge desirability and resale value. And in this segment for top-dog SUVs, desirability and badge appeal count for more than usual. In a few years’ time, when the Cayenne’s high residuals will still keep it beyond the financial means of most, a well-kept X5 4,8i may just be one of the biggest bargains around.

Also consider:
Following the recent facelift, a lot better looking though still not as stylish as the BMW. More powerful than the X5, and remains the class leader from a dynamics point of view. Bullet-proof residuals.
Down on power, but a new 5.5-litre V8 engine will soon address that criticism. Remains a very strong rival, with excellent comfort levels and superior rough-road ability, should it be needed.
This German is well-priced and has been popular with South Africa’s fashion conscious. Imposing looks and a well-built cabin that offers seven seats are big attractions, but dynamically it can’t match the Porsche… or the BMW.
