MG3 Review (2026): A $20,990 Light Car With a 155kW Hybrid Surprise

The MG3 is the car that anchors MG's range at the bottom and does a lot of the heavy lifting in the brand's sales. It is a light hatchback aimed squarely at first-car buyers, downsizers and anyone who just wants cheap, easy transport, and the latest version throws in a genuinely surprising hybrid. Here is the data-led take.

How much is the MG3?

Five grades across petrol and hybrid. All prices are before on-road costs.

That $20,990 starting price puts the MG3 among the very cheapest new cars on sale, alongside the Suzuki Swift and a shrinking handful of others. The hybrid premium of about $7,000 over the base car is significant in this segment, but you get a wildly different car for it.

The hybrid is the star

The petrol grades are exactly what you expect from a budget light car: an 81kW/142Nm 1.5-litre engine, a CVT, a claimed 6.0L/100km, and a job done without fuss. They are cheap and cheerful city runabouts.

The Hybrid+ is the one that turns heads. It makes a combined 155kW and 425Nm, which is an extraordinary amount for a car this small, more than double the petrol's output and more grunt than many mid-size SUVs. The result is a light hatch that is genuinely quick, with strong electric torque off the line, while still claiming just 4.3L/100km. It is the rare case of a hybrid that is bought for performance as much as economy, and at $27,990 it badly undercuts other hybrid hatchbacks.

Dimensions and practicality

At 4,113mm long on a 2,570mm wheelbase, the MG3 is a true light car, so think of it as roomy enough for two adults up front and kids or occasional adults in the back, rather than a family hauler. The 10.2m turning circle makes it easy to park, and the light kerb weight (1,199kg petrol, around 1,300kg hybrid) helps it feel nippy. The petrol's 45-litre fuel tank gives it long range between fills; the hybrid runs a smaller 36-litre tank but goes much further on it thanks to the economy.

Inside, the MG3 punches above its price with a central touchscreen, a clean modern layout and more soft-touch material than you used to get at this money. As with all value cars, the infotainment is functional rather than slick, but nothing about the cabin feels as cheap as the sticker.

Running costs

The petrol MG3 at 6.0L/100km costs roughly $1,710 a year in fuel over 15,000km at $1.90/L. The hybrid at 4.3L/100km drops that to about $1,225 a year, a saving of nearly $500 every year, and that gap widens the more city driving you do, where the hybrid is at its best. Over several years of ownership the fuel saving claws back a meaningful chunk of the hybrid's higher purchase price, and you get the performance as a bonus.

Safety and ownership

This is the MG3's one real caveat. It holds a 4-star ANCAP rating dated 2024, not the maximum five stars that most rivals now achieve. It still comes with autonomous emergency braking, lane-keep assist and the expected active-safety features as standard, but if a 5-star rating is non-negotiable for you, that is the trade-off for the low price. On ownership, MG's 10-year/250,000km warranty is the longest in the class, with servicing every 12 months or 10,000km. Resale on newer MGs is still establishing itself.

How it compares

The closest rival is the Suzuki Swift, which is lighter, more fun to throw around and carries a 5-star rating, but cannot match the MG3 Hybrid for power or the MG's warranty. The Toyota Yaris is the quality benchmark and holds its value best, but costs noticeably more. If you like the MG ownership package but want an SUV body, the MG ZS is the next step up. For outright value and surprising hybrid performance, the MG3 stands alone.

The verdict

The MG3 is a clever little car. As a $20,990 petrol it is simply one of the cheapest ways into a new car with a long warranty. As a $27,990 hybrid it is something more interesting: a light hatch with mid-size-SUV power and frugal economy that nothing else in the class can match. The 4-star safety rating is the honest catch, and you should weigh it against the price. But if value and surprising performance top your list, the MG3 Hybrid is one of the standout budget buys of 2026.
