Tata Curvv: which powertrain?

Prices from Tata's own variant price list for New Delhi, read 28 Oct 2026: 15 standard versions, which match the brochure's powertrain matrix cell for cell (October 2026 Series X brochure). Left out: the 11 #Dark versions (₹20,000-₹25,000 over the trim they are built on), which add Carbon Black paint, black wheels and black leatherette and nothing our registry prices. The Hyperion direct-injection petrol and the diesel automatic are sold only on the Accomplished X+. Equipment from Tata's per-variant specification list on its own site, checked against the brochure's feature walk, in which each trim is stated as additions over the one below (Pure X over Smart X, and so on to Accomplished X+ over Accomplished X); they agree. Paddle shifters are on every DCA. Level 2 ADAS (adaptive cruise, autonomous emergency braking, lane keep) is on the Accomplished X+, which is sold only as a DCA, and the brochure says adaptive cruise is available in DCA. Smart X has no infotainment unit at all, so no audio is credited. Mapping: the 10.16 cm (4-inch) cluster on Smart X to Pure X+ sits below the lowest cluster rung and earns nothing; the 10.25-inch digital cockpit from Creative X+ earns the full digital cluster; the 12.3-inch screen from Accomplished X earns the 12.3-inch rung; the Ergo Lux 6-way powered driver's seat sits at the 4-way rung; the 9-speaker JBL system with a subwoofer earns premium sound; the 'Blind View Monitor' camera view earns the blind-spot monitor from Creative X+; the R17 AeroStyle wheels on Smart X and Pure X are listed by Tata as a different wheel type from its alloys and sit at the wheel-cover rung; the 'TPMS' from Creative X+ is listed separately from the iTPMS (indirect) on Pure X and Pure X+, so it is credited and the iTPMS is not. NOT CREDITED, each because the maker says less than our entry needs: a rear wiper (only a rear defogger, from Creative X+, is listed); a connected tail lamp (the Light Saber tail lamp on Accomplished X+ is not described as connected); the dashboard mood lighting on Accomplished X+ (dashboard only, not doors); the Serenity Screen rear sunshade (not the rear-door sunshades the registry prices); tilt steering (no telescopic adjustment); the electric tailgate switch on every trim and the gesture-powered tailgate on Accomplished X+ (not registry features). Tata prints the engines in kW: Revotron 88.2 kW and 170 Nm, Hyperion 91.9 kW and 225 Nm, Kryojet 86.7 kW and 260 Nm. Tata publishes no certified fuel efficiency for any Curvv powertrain, so none is stored.
