The Tata Sierra specifications read like a proper SUV spec sheet, built around space and engine choice. The body measures 4340 mm long, 1841 mm wide and 1715 mm tall, on a 2730 mm wheelbase. That footprint gives five people room to spread out. The tall roof adds head room front and rear.
Three engines sit on the Tata Sierra specifications list. The 1.5 litre petrol makes 105 bhp and 145 Nm, easy going in town. The 160 bhp turbo petrol brings 255 Nm for stronger response when you push on. The 1.5 litre diesel delivers 116 bhp and up to 280 Nm with the automatic, ideal for loaded highway runs.
Gearboxes vary by engine on the Sierra. Most trims use a six speed manual, the petrol adds a seven speed DCA, and the diesel offers a six speed automatic. Tata has not published ARAI mileage yet, so treat any economy talk as a guide. The diesel should prove thriftiest on the highway, while the turbo drinks most when driven hard.
Practical numbers stand out here. The 622 litre boot is large for the class, and the 205 mm ground clearance suits rough roads. The 50 litre fuel tank supports long drives between fills. Seating is five, on a wide, supportive rear bench with usable knee room.
Safety and comfort kit climb steadily with the trims, so read the ladder before you buy. Higher versions add more airbags, driver aids and cabin tech. See how the Sierra engines line up across trims, since the engine you pick shapes running costs more than the trim does.
