Questions you may find useful

I am looking to buy a new EV for my daily office commute, which is roughly 100 km round-trip. My current ride is a Toyota Innova Crysta. While it is a reliable workhorse, I find it increasingly tiring for daily use. The constant body roll, low-speed bounciness, and typical ladder-frame wobble over uneven roads are wearing me down. I want to switch to a smooth, refined electric SUV. My usage will be a mix of self-driving and being chauffeur-driven. My absolute top priorities are: Ride Comfort & Stability: I need a car that glides over bad roads, handles speed bumps cleanly, and minimises vertical movement/head-toss. I want to avoid the wobbliness of the Crysta at all costs. Cabin Space: Generous legroom, good under-thigh support, and a spacious cabin environment are highly important. I am currently considering four upcoming/recently launched options, but I am torn between them: Mahindra XEV 9e, Mahindra XEV 9s, Tata Sierra EV, Tata Harrier EV. Given my 100 km daily run, battery efficiency is a factor, but comfort overrides everything else. Which of these four will offer the most stable, plush, and fatigue-free ride for someone moving away from an Innova Crysta? I do not intend to sell the Innova Crysta, as I want to keep it for the airport and family runs for long distance.
