What is Munich playing at? The X3 is to the 3-series what the X5 is to the 5-series. Yet its wheelbase is just 25mm longer (yes, just one inch), overall length is but an additional 102mm, width varies by only 10mm and height by 46mm. The X3’s 480-litre boot is 15 litres bigger and, in most important dimensions, interior roominess is virtually identical.
Their 3.0-litre engines both develop the same 228bhp, while the money difference between the £32,015 X3 and its marginally higher- priced challenger is a mere £1130, or 3.5 per cent. In other words, the two could hardly be closer. And because it’s 235kg lighter, the X3 is quicker – 7.8sec to 62mph versus 8.5sec – and uses nine per cent less fuel.
Of course, we’re dealing here with the top X3 model (versus the bottom X5 model), for that is BMW’s (lucrative) way of launching new cars. Already, BMW GB has announced a £28,615 2.5-litre X3 and confirmed the summer ’04 arrival of the 3.0-litre turbodiesel, that’s expected to be priced almost identically to the 3.0-litre petrol. More affordable, four-cylinder petrol and diesel engines are in the pipeline, to further distance X3 from X5, but there are no plans for an X3 V8. Still, that bizarre size similarity remains. What we can be sure of is that the next-generation X5, due in 2006, is certain to be pumped up in all major dimensions.
Drive them and you’ll feel the difference, the engineers claim. So we did and, yes, the X5 is more macho, while the X3, aimed at a younger buyer, is lighter on its feet, the driving position not quite as commanding as the taller, older model. However, they are really not that different.
‘We have two offerings [in the same class],’ admits one senior Munich marketing man. ‘You can have two varieties of apples,’ he says, explaining that there is a size below which Americans won’t take any SUV seriously. That size, apparently, is defined by the X3.
BMW says the X3 is built on a new platform. True, but only up to a point. In fact, the front suspension is derived from the X5, the rear from the 3-series four-wheel- drive.
The X3 does, however, adopt BMW’s new design language. No, the X3’s not quite as radical as other recent BMW designs, but it is going to split opinion just the same.
