Long-Range RWD up to ~ 600 km WLTP in some markets; strong efficiency.
Competitive WLTP range: e.g. ~ 482 km for RWD “Premium” export model, ~ 456 km for AWD Performance.
IM6 Performance ~ 505 km; some trims around ~ 555 km WLTP; smaller trims ~ 450 km.
Acceleration / Performance
Performance version: ~ 3.5 s 0-100 km/h (in some trims); other trims slower.
Sealion 7 Performance is strong, but tends to lag Tesla in some performance metrics. E.g. AWD version ~ 4.5 s in some configs.
Very strong in Performance AWD: 0-100 km/h in ~ 3.4 s in the IM6 Performance in tests.
Interior / Comfort / Tech
Tesla continues with minimalist aesthetic; recent updates (Juniper refresh) improved aerodynamics, comfort, interior tweaks. Good build generally, but still critiques.
BYD has been praised for premium cabin feel, large rotating screen, good interior materials. Tech well-equipped.
IM6 gets high marks for interior space, premium finish, quality of materials. Some critiques about ride comfort (can be jittery), and tech overload.
Charging / Fast Charging
Tesla’s Supercharger network is a plus (depending on region). Charging infrastructure strong.
Sealion 7 has fast-charging capabilities; export versions support decent DC charging power.
IM6’s electric architecture includes 800V capabilities in certain trims, allowing faster DC charging.
Price / Value / Warranty
Tesla tends to be pricier, especially with performance trims; resale value strong; service & charging advantages in many parts.
BYD is usually well-priced for what it offers; strong competitive value, especially in its home market and export markets entering now.
MG IM6 often undercuts Tesla in some markets; generous features; warranty is decent, though in some areas service network etc may lag Tesla.
Pros & Cons: Which Might Be Best Depending on What You Care About
Here are some use-cases / priorities and which car looks better for each:
Priority
Best Pick / Why
Maximum real‐world range + efficiency
Tesla Model Y (Long-Range trims) – best overall if you want longest distance between charges, low energy consumption.
High performance / acceleration
MG IM6 Performance is very fast; Sealion 7 Performance is strong too; Tesla in its Performance spec competes well. If you want sportiness, MG or Tesla Performance.
Interior luxury & tech features
BYD Sealion 7 & MG IM6 shine here (huge screens, premium interiors) more than Tesla for some users, depending where you are.
Charging infrastructure & reliability
Tesla (where Superchargers exist) still has a big edge; else it depends on your local charger network.
Value for money
MG IM6 & BYD Sealion 7 often offer more kit per dollar/euro; if you don’t need top Performance trim, they can get you a lot more car.
Weaknesses / Things to Watch Out For
Tesla: Interior can feel utilitarian; depending on market, build-quality (fit, finish) still criticized in some reviews. Performance trims cost a lot. Service / repair costs / parts availability can be an issue depending on country.
BYD Sealion 7: The tech is good but some “quirks” noted; some versions have less efficient power delivery; export versions sometimes have reduced charging spec vs home market. Also, dealer/service network might be less mature.
MG IM6: Ride comfort can suffer (bumps, road imperfections) especially in Performance or sporty trims; heavier car, possibly higher energy use; some tech feels “overloaded” or still being polished.
My Tentative Verdict
If I had to pick one, here’s how I’d decide:
If I want best all-rounder (range, efficiency, good charging network, reliability), Tesla Model Y still likely edges out the others.
If I care more about value + tech + “luxury feel” at a lower price, MG IM6 might be the more attractive choice.
BYD Sealion 7 is tempting and strong, especially if it fits well in your market, but in many cases it trails Tesla on top range and MG on some performance specs.
