Tesla Model 3 vs BYD Seal vs MG IM5: Performance EV Showdown (2026)

2026 Tesla Model 3 Performance vs BYD Seal Performance vs MG IM5 Performance: A Comprehensive Comparison Review

All three of these electric cars have 'performance' in their names and pack a punch. But which is best – and which is a true performance car that's as good on a country road as it is around town?

Summary

Tesla Model 3: The most engaging of these three, so it’s the one we’d love to see fitted with simulated gear shifts and engine sounds, as in a Hyundai Ioniq 5 or Ioniq 6 N, which make for an even more connected driving experience.
BYD Seal: The slowest car in this group – zero to 100km/h in a claimed 3.8 seconds (or 4.0sec as tested) – but you’d be hard-pressed to call the Seal Performance slow.
MG IM5: On paper, the IM5 might not look like an agile and dynamic car to drive, at 2.3 tonnes in weight, more than 4.9 metres nose to tail, and a wheelbase longer than that of a Toyota LandCruiser.

Interior and Technology

Tesla Model 3: Minimalism is the name of the game inside the Tesla, with a single 15.4-inch touchscreen hosting most vehicle functions – and little in the way of conventional switchgear.
BYD Seal: Leather-like materials are used on most touchpoints – the armrests, door panels, and even the centre-console kneepads – plus supple suede-like door accents, and good perceived build quality without squeaks or rattles.
MG IM5: The IM5 is like no other MG sedan before it, and it makes quite the impression on the inside. There is rarely a straight line to be seen, with an abundance of curves and wavy shapes, supple leather-like materials everywhere you can touch, and a few metallic trim elements to contrast the grey leather-look upholstery in this test car.

Charging and Range

Tesla Model 3: The fastest of the group, needing 33 minutes to go from 10 to 80 per cent in Model Year 2025 examples, or 32 minutes and 40 seconds in MY26 builds.
MG IM5: The fastest, boosting from 10 to 80 per cent in an astonishing 17 minutes and five seconds as tested, thanks to a claimed 396kW peak charging power.

Safety and Warranty

Tesla Model 3: The best of the bunch, with lane-keeping and driver attention warnings that do not annoy, traffic sign recognition that can be permanently set to a visual alert only, and quality parking cameras.
BYD Seal: The brand has come a long way in tuning its crash-avoidance features to work with the driver, not against them, but we still have a few gripes.
MG IM5: The most intrusive of the bunch. The driver attention monitor is overzealous and beeps at the driver for brief glances away from the road, and the speed sign recognition will chime when the car exceeds the speed limit it has detected, even if it has misread the sign.

Conclusion

Tesla Model 3 Performance: The winner of this comparison. It is the most expensive car of the bunch, and lacks a few features from the others – Apple CarPlay and Android Auto, chief among them – but it feels like the finished article.
BYD Seal Performance: Incredible value for money. It’s the cheapest car here by a significant margin, but it’s still spacious inside, well equipped, loaded with technology, and easy to live with day-to-day.
MG IM5: Leans even further into luxury grand tourer territory, with a lavishly appointed cabin and loads of high-tech tricks, backed up by immense acceleration, capable roadholding, and fast-charging performance that blows its rivals away.
