The new model is based on the same platform as the X3 but will be a four-seater with a more coupe-like profile. It’s just like the relationship between the X5 and the X6.
The newcomer will be available with all of the same engines as the X3, so that means a diesel only line-up. Kicking it off is a 141bhp 2.0-litre diesel, with a 309bhp 3.0-litre diesel topping the range.
When the X4 goes on sale late in 2013 it will be priced just above the X3, so expect to see a price tag of around £30,000.
