So you want a SUV that's quick, economical, with plenty of gadgets....Keep an eye out on the Tesla for the model X details..
It wouldn't be cheap, probably start at £60K, but will be based on the Model S drivetrain. So basic spec will be:
All wheel drive
250 mile range (on £8-10 of electricity at peak rate - Half that if charging via off-peak rates)
0-60 in around 5 seconds
8 year and UNLIMITED miles warranty on the drivetrain
More gadget than an Apple store
Memory seats + mirrors
FREE use of Tesla supercharges for LIFE!!
and Gull wing doors
But apparently already a 20,000 waiting list, so you might be waiting a while, delivery due to start Sep-Oct this year (2015) :)
