The Tata Sierra EV, launched in late June 2026, revives an iconic nameplate in fully electric form and positions itself as a capable, long-range electric SUV. It directly competes with the MG Windsor EV, a popular crossover utility vehicle (often described as a CUV or MUV-like) that has been a bestseller in India’s electric segment thanks to its competitive pricing, innovative Battery-as-a-Service (BaaS) option, and spacious cabin.
While the Sierra EV emphasizes range, performance (including an all-wheel-drive option), and premium SUV features, the Windsor EV focuses on affordability, everyday practicality, and value-driven ownership for urban and family buyers.
Pricing and Variants
Tata Sierra EV starts at ₹18.79 lakh (ex-showroom) for the entry-level Pure 63 kWh RWD variant and extends up to ₹25.99 lakh for the top Empowered A 75 kWh QWD (Quad Wheel Drive). It offers multiple personas—Pure, Pure S, Adventure, Empowered, and Empowered A—with 63 kWh and 75 kWh battery options. Introductory pricing makes it aggressive in the midsize electric SUV space.
MG Windsor EV is significantly more accessible, with prices ranging from around ₹14 lakh to ₹18.39–18.60 lakh (ex-showroom) depending on the variant and battery. It comes in variants like Excite, Exclusive, Essence, and Pro versions. The standout BaaS model lowers the upfront cost (e.g., starting near ₹10 lakh + battery rental per km), making it appealing for cost-conscious buyers. The Sierra EV commands a premium of roughly ₹4–8 lakh over the Windsor, justified by its larger batteries, superior range, and more advanced powertrain options.
Battery, Range, and Performance
The Tata Sierra EV offers two lithium iron phosphate (LFP) battery packs: 63 kWh (MIDC range up to ~565 km, real-world C75 estimate 440–460 km) and 75 kWh (MIDC up to 665 km, real-world 510–530 km). The top QWD dual-motor version claims 624 km MIDC. It supports 120 kW DC fast charging (20–80% in ~25–26 minutes, adding up to 263 km in 15 minutes) and includes V2L/V2V capabilities.
Power outputs vary: 63 kWh RWD models deliver around 238 PS and 315 Nm, while 75 kWh versions offer strong performance, with the QWD dual-motor setup producing up to 306 PS combined and 504 Nm torque. The QWD variant accelerates 0–100 km/h in 5.8 seconds in Boost mode. It includes terrain modes for better off-road or varied-surface capability.
The MG Windsor EV uses smaller batteries: 38 kWh (claimed range ~331–332 km) and 52.9 kWh (~449 km). It features a single front-mounted motor producing 134 bhp (around 136 PS) and 200 Nm torque. DC fast charging (45–60 kW) takes about 45–50 minutes for 0–80%. AC charging is slower, around 6.5–9.5 hours depending on the pack and charger.
The Sierra EV clearly leads in range and performance versatility, making it better suited for highway trips and varied conditions, while the Windsor prioritizes efficient urban commuting.
Design, Dimensions, and Practicality
The Sierra EV is a traditional 5-seater electric SUV with modern styling that nods to the original Sierra, built on the Acti.ev+ platform. It offers strong road presence, with features like LED lighting, up to 18-inch wheels, and good ground clearance for an SUV. Boot space is competitive (reports vary around 447–622 litres).
The Windsor EV adopts a crossover/MUV-like design with flush door handles, connected lighting, a panoramic glass roof option, and Aero-Lounge reclining rear seats. It provides impressive interior space on a 2,700 mm wheelbase, with boot capacity around 579–604 litres—excellent for a family hauler in its class. Both are 5-seaters, but the Windsor often feels more MPV-like in rear comfort and space, while the Sierra offers a more rugged SUV stance and capability.
Features and Technology
Tata Sierra EV impresses with a technology-heavy cabin, including a Horizon View triple-screen setup, ventilated seats, panoramic sunroof (higher trims), wireless charging, premium audio, Level 2+ ADAS, 360-degree/540-degree camera, auto park assist, digital key, OTA updates, and advanced connected features. Safety includes 6 airbags, electronic stability programs, and a lifetime battery warranty (terms apply).
MG Windsor EV stands out with a large 15.6-inch touchscreen, 360-degree camera, Level 2 ADAS (in higher variants), ventilated seats, ambient lighting, wireless connectivity, and reclining rear seats. It also offers strong connected car features via i-SMART. Safety covers 6 airbags and standard assists.
The Sierra edges ahead in premium tech and drive assists, while the Windsor delivers standout comfort features like the panoramic roof and lounge seats at a lower price point.
Which One to Choose?
The Tata Sierra EV suits buyers seeking superior range (over 500 km real-world in top variants), stronger performance, AWD capability, and a more traditional SUV experience. It is ideal for those planning longer drives, occasional off-road use, or wanting future-proof battery tech with Tata’s established EV ecosystem and service network.
The MG Windsor EV remains a bestseller for good reason: lower entry price (especially with BaaS), spacious and comfortable cabin, adequate range for city/highway mixes, and feature-packed value. It appeals to urban families and first-time EV buyers focused on running costs and practicality.
In summary, the Sierra EV raises the bar on capability and range in the segment, while the Windsor continues to win on affordability and clever ownership solutions. Test drives are essential, as the choice ultimately depends on budget, daily commute needs, and preference for SUV stance versus crossover comfort.
