I've just been through a similar search and in conclusion the XC40 has now gone out to a November delivery. It then depends on what other features of an SUV you are after, I was looking for 4wd and petrol which greatly limits the choice.
A lot of smaller SUV's only offer front wheel drive and a lot only offer diesel for it's torque. However diesel is being hit by governments at the moment and I suspect that is only going to get worse.
If you need some pulling power then you'll be looking at quite an expensive Petrol engine New discovery/Jag E-pace have a 250bhp engine as does the XC40. In my case the discovery was a bit too long and quite expensive when kitted out with goodies, the E-Pace was also similarly expensive with a reasonable set of toys. From what I've seen the 'premium' brands are a better quality but tend to be priced with few options.
At the start of our search we were looking at a 2.0L TFSI Q2, that has proved to be a bit small and I've lots with "little old ladies" in
The Q3 is a very old model now and to be replaced later this year. The new Q5 from 2017 can come with a 250bhp petrol Quattro setup.
If you're happy with diesel the options broaden and I suspect the offers do too as many dealers are having trouble shifting stock.
Don't forget the newer road fund rules mean anything over £40K will suffer an enhanced charge for a few years
If you are however not look at the premium brands then pretty much everyone has an SUV type vehicle from Dacia upwards LoL.
Andi.
