The odd thing is that Cupra Ateca DOES have electric seats in some EU countries, but Seat UK have seemingly decided against offering that option. Not sure why - suspect that they may have been trying to hit a maximum price point (£40K for tax reasons???), though a fully loaded CA does (slightly) exceed £40K. But still seems odd not to offer it as an option, though I suppose it could happen in the future.
Two other thoughts: First, while the Ateca's infotainment system is a few years old now and could do with a better processor, slightly larger screen etc, there's no doubt to my mind that it has a better mix of touchscreen and mechanical controls. I'm not anti-touchscreen but there are some controls that are just ergonomically better done with a mechanical control, like selecting drive mode.
Second, I've come to the conclusion that most manufacturers just don't see a market slot for a smaller but premium 4WD SUV with strong performance, at least not one that could make a £40K price-point. In other words, if it's relatively small then no-one is going to pay significantly over £40K. So anything that could be described as a compact performance SUV is automatically a non-premium model with significant economies made in its fixtures & fittings. The only exception to that right now is the new Evoque P300, though an (R)SQ3 could be a challenger too if one ever appears.
Part of the story may also be that many manufacturers are on the cusp of launching their EVs in this sector, which if they're endowed with twin motors and a decent battery will probably have a strong performance. IOW now is not the right time to be looking for this class of car. In a year's time the XC40 EV T99 with the new Sensus could be a much more inviting proposition. But I just can't wait that long!
