The Q7 owes its heritage to the Porsche Cayenne/Volkswagen Touareg, the Q5 to Audi’s new A4. The major differentiating factor is height – the Q5 is some 210mm taller than the A4 – but in other respects the two share similar dimensions, with practically identical wheelbases, while the Q5 is fractionally wider and, surprisingly, a little shorter.
The extra height and glass area takes it toll on the scales. The Q5’s claimed 1730kg kerb weight is around 135kg heavier than a similar A4 quattro, and with options our test car weighed a hefty 1880kg.
The new Q5 doesn't share its underpinnings with the A4 per se, with the next gen adopting the Volkswagen Group's MLB platform, which is already used on the current generation A4 and Q7. Overall both Q5s are similiar in size, with the second generation incorporating better packaging to improve interior space.
Unlike the current generation, there are also plans to create for the first time a RS Q5 to follow a similar move for its smaller sibling - the RS Q3. Not many details exist about this hot Q5, but it is said to include Audi's 3.0-litre V6 petrol engine.
