Quick HighlightsTesla upgrades the India-spec Model Y Long Range RWD with a 84.2 kWh battery, up from ~79 kWh.Claimed WLTP range increases by almost 40 km, from 622 km to 661 km.Prices remain unchanged: Long Range RWD starts at ₹67.89 lakh (ex-showroom).No changes in powertrain or performance metrics; this is a capacity + efficiency upgrade.Tesla’s Quiet India Upgrade: What’s NewTesla has quietly upgraded the battery of its India-spec Model Y Long Range RWD, boosting its WLTP-certified range without altering the price tag. Earlier, the Long Range model was offered with a battery pack close to 79 kWh and claimed 622 km of WLTP range. With the new update, the battery has been upped to 84.2 kWh , which brings the WLTP range to 661 km , an increase of 39 km.This enhancement aligns the Indian variant with the latest global spec seen in some markets and leverages Tesla’s shift to newer LG battery chemistries — higher energy density and efficiency enabling more usable capacity.Technical & Performance InsightsThe motor and drivetrain remain unchanged. The electric motor on the rear axle still handles propulsion; the 0–100 km/h time remains 5.6 seconds.Tesla achieves the extra range primarily via the increased battery usable capacity (an additional 5.2 kWh) combined with improved battery efficiency.Under ideal DC fast-charging, the Long Range variant claims to add 267 km of range in 15 minutes.The Standard RWD variant remains unchanged with this update.Pricing & Market PositioningTesla’s strategy here is notable: it has kept existing ex-showroom prices despite the upgrade. The Long Range RWD continues to be priced at ₹67.89 lakh , and the base Standard version remains priced at ₹59.89 lakh ex-showroom. This means customers who booked or will book the Long Range variant automatically inherit the improved battery spec without paying more.This move could help mitigate price sensitivity, particularly in India’s competitive EV market, by offering more value and stronger range credentials — a powerful marketing point when range anxiety remains a key barrier to adoption.Implications & Strategic AngleStronger competitive edge : The 661 km WLTP range places the Model Y ahead of many rivals in the Indian EV market in terms of claimed range.Psychological advantage : Communicating “no price increase, more range” amplifies value perception among prospective buyers.Battery supply strategy : The shift to LG’s newer cell chemistry suggests Tesla is optimizing its supply chain and cost-per-kWh metrics, possibly enabling efficient upgrades in other markets too.Real-world gains : While WLTP figures offer one benchmark, the improved battery margin could translate to fewer charging stops and better buffer under real-world conditions (hot climate, highway + city mix).Challenges & RisksRange claim vs real world : WLTP ratings tend to be optimistic; gains in actual driving range will depend heavily on driving conditions, climate, payload, speed, and usage of AC/heating systems.Charging infrastructure : The extra capacity is meaningful only if India’s DC fast-charging network keeps pace to enable long-distance travel convenience.Battery degradation & warranty : As battery chemistry evolves, health over the life of the vehicle will be closely watched by consumers.Expectation setting : There might be customer expectations of further upgrades in the future (e.g. Performance/AWD versions), so Tesla must manage roadmap clarity.ConclusionThis battery upgrade is a calculated, low-risk move by Tesla in India — more range at no extra cost. It reinforces Tesla’s commitment to delivering the latest tech in its international markets even after initial launch. For Indian EV shoppers, the decision tilts further in favor of Tesla’s offering, especially for those seeking long-range SUVs without paying a premium.
