The Tata Sierra and Mahindra XUV700 belong to completely different segments in terms of size, engines and price. We have yet to drive the Sierra, but based on confirmed details, it is a Creta-sized SUV at about 4.3 metres. It will offer three engines: a 1.5 litre turbo petrol, a 1.5 litre turbo diesel from the Curvv, and a 1.5 litre naturally aspirated petrol, which is likely to be the volume seller. Tata Sierra prices are expected to start around ₹11 lakh for the base variant and go up to about ₹20 lakh for the top trims.
The XUV700, on the other hand, is a segment above and rivals the Tata Harrier and Safari. It is much larger, gets more powerful 2.0 litre turbo petrol and 2.2 litre turbo diesel engines and also offers a seven-seat layout. Naturally, it will be significantly more expensive than the Sierra, especially in the higher variants.
Given that most of your driving will be on the highway and you want something powerful, the XUV700 will suit your needs far better.
