The best strong hybrid option for your budget right now is the Maruti-Suzuki Victoris. It is a part of having an efficient hybrid powertrain that is well-equipped and easy to drive. 

You could also look at the Victoris’s sibling, the Grand Vitara Hybrid, which is being offered with some discounts now, as a facelift is coming soon. There is no timeframe announced for the implementation of BS7, and there are no BS7 cars available in the market either. 

Getting a BS6 model today won’t make your car obsolete even when BS7 norms come, which is unlikely to be before 2028. 

Broadly speaking, the higher you sit in a car, the more comfortable you are, which is why SUVs and MPVs are more comfortable over long drives. But it's not just the height of the car but lots of other factors like the ‘H-Point’ (the distance between your hip and the floor) under thigh support, the seat cushioning and finally the driving position which impacts comfort on a long drive.
 

Given your requirements, you should consider the Toyota Hyryder, Maruti Suzuki Grand Vitara and Victoris strong hybrid. Since your usage is high, you'll benefit from the exceptional fuel efficiency of the same strong hybrid-petrol powertrain that powers all three. The Hyryder and Grand Vitara mileage is 27.97kpl, while the Victoris mileage is 28.65kpl, which is slightly higher (claimed). 

All three SUVs also come equipped with all the features you want in their respective top-end trims - a panoramic sunroof, ventilated seats, alloy wheels, a touchscreen infotainment system and much more. 

We would recommend you go for the Maruti Victoris since it's the newest of the lot. It has the most features and also a 5-star Bharat NCAP crash safety rating, which the other two don't have. 

As for pricing, the top-spec Victoris ZXI+ (O) string hybrid is priced at Rs 19.99 lakh, while the Grand Vitara Alpha+ (O) costs Rs 19.72 lakh and the Hyryder V is priced at Rs 19.76 lakh (ex-showroom, India). 

The Maruti Brezza and Toyota Hyryder are in two different segments, and which one you buy really depends on your specific requirements. The Brezza is a compact SUV that sits within the 4 meter length. Also, it is good for cities with its compact dimensions and a nice, cushy, low-speed ride.

However, since you drive more on the highway, the Hyryder would suit you a little better as highway stability is very good, and the ride and handling balance is well set up. Both cars, however, aren't punchy out on the highway. Also, do bear in mind the Toyota Hyryder is essentially the Maruti Grand Vitara, so you could also consider this in case you get a better deal.
