For city use, the Toyota Fortuner is not ideal. Since you have private parking that accommodates a charger, this is a perfect time to switch to an EV. The Mahindra XEV 9E is more appealing than the Harrier EV, but the Mahindra XEV 9S is the one to focus on because it is more practical and also costs less. 

It offers enough range for your 100 km weekend runs, has sufficient power and torque to tackle steep inclines, and has adequate ground clearance for rough roads. The Fortuner will handle rough roads better, but given that it is much more than the 9S. It is hard to justify the extra spend for occasional rough-road use.
 

As you rightly said, the Toyota Innova HyCross is better from the rear seat, while the Tata Harrier EV is more enjoyable from the front. It's up to you to decide where your priority lies. 

When it comes to performance and dynamics, the Harrier EV ticks more boxes, as it has a much stronger and more responsive powertrain, sharper steering, tighter dynamics and a pretty comfortable ride in isolation too. 

However, its shortcoming is that of all EVs - the limitation of range and dependency on charging. Plus, the Harrier EV has shown signs of electronic glitches, at least on early cars. 

If these are things you can work with, the Harrier EV seems like the better choice for you. The Innova, meanwhile, is the better all-rounder. It's more spacious and comfortable, with rock-solid reliability and a seamless service experience. 

The Toyota Innova HyCross is a 6-7-seater MPV that ranks high on reliability and dependability. With Toyota's strong backing, your ownership experience over the next 10 years is likely to be hassle-free. 

The Tata Harrier EV, on the other hand, is a fantastic product with all the bells and whistles which you may or may not expect at its price. And while the driving experience of the Harrier EV is superior to the Hycross', Tata doesn't have a reputation for a niggle-free car, and its service centre experience can be a hit or miss. 

So even though the Harrier EV is a good car, for sheer peace of mind, the Toyota Hycross is a better bet.

Given your budget, and that you are a performance enthusiast, you should check out the Tata Sierra with the new 160hp, 1.5-litre turbo petrol engine. It comes with a smooth 6-speed torque converter automatic, which means there should be less of the rubber band effect that you might have gotten with a CVT auto. 

The Skoda Kushaq 1.5 petrol is another good option, although there is a facelift due in the second half of next year, which will bring many new features. While an EV is also a good option, the Tata Harrier EV will be slightly out of your budget, and the Tata Sierra EV will only be launched in 2026.
