New MG3 Deals

Beyond the headline figures, the MG3 is built around the week-in, week-out job of a British supermini: short school runs, supermarket car parks, the occasional motorway stretch between visits to family. The hybrid system is tuned for exactly that pattern of use, which is where its efficiency genuinely shows up rather than only on a test cycle.

Want to see the self-charging hybrid in action before you order? Our MG3 Review above focuses on the Hybrid+ specifically, walking through the cabin, the tech and how the petrol-electric system behaves on the road.

New MG3 Interior

Open the door and the MG3 Hybrid interior feels a size up from what the exterior promises. The all-black interior pairs a 10.25-inch floating touchscreen with a fully digital 7-inch driver display, both standard across the range. The dashboard reads as one continuous surface rather than a screen bolted onto a conventional cluster. That means less time glancing down to find the control you want and more time with your eyes on the road. Chrome detailing and high-gloss panels pick out the edges, and a soft-touch multifunction steering wheel keeps the frequently used controls under thumb.

That steering wheel sits in front of a driver's seat with six-way adjustment as standard, four-way for the front passenger, so dialling in a comfortable position is a two-minute job rather than a compromise. Choose the Hybrid+ Trophy and the seats are finished in leather- and suede-style upholstery, with heated front cushions and a heated steering wheel. That combination pays off on the first frost of autumn and keeps paying all winter. You can set off with warm hands on the wheel rather than scraping ice off it one-handed before you have pulled onto the road.

Practicality is where the MG3 quietly out-punches its footprint. The boot swallows 293 litres with the rear seats up, expanding to 983 litres with the 60:40 split-folding bench down. A pram, a weekly shop, or a pair of golf bags all go in without rearranging the household first. Smart storage touches, from the adjustable cup holder to the front centre armrest with storage, mean the small items that usually migrate to the passenger footwell have somewhere to live instead.

New MG3 Exterior

From the kerb, the MG3 reads sharper than its segment usually allows. A wide, open front grille sits beneath integrated LED daytime running lights, giving the car a planted stance that photographs well and, more usefully, makes it easy to spot in a busy car park. The silhouette tapers through a rising shoulder line into light-trailed rear tail lamps, and a sporty rear spoiler at the top of the tailgate finishes the roofline without pushing the design into boy-racer territory.

Those 16-inch Atlas alloys do more than fill the arches: their spoke pattern is shaped to reduce drag, a small aerodynamic gain that supports the Hybrid+ model's 64.2 mpg combined figure. Electrically adjustable, heated, body-colour door mirrors are standard throughout the range. Rear parking sensors with a reversing camera come fitted across all three trims, taking the stress out of parallel parking on a terraced street.

MG3 Specs and Trims

The MG3 is offered in three trims across two powertrains: the MG3 Petrol SE, the MG3 Hybrid+ SE, and the range-topping MG3 Hybrid+ Trophy. The table below sets out the equipment split, with features and safety kit grouped by category so you can see at a glance what each step up adds.

MG3 Engines and Performance

The MG3 keeps the powertrain choice simple: a conventional 1.5-litre petrol with a manual gearbox, or a self-charging hybrid pairing the same displacement with an electric motor and a three-speed automatic transmission. The table below sets out the performance, economy and emissions figures for each.

WLTP figures are for comparison purposes and may not reflect real-world driving. Economy and CO₂ figures vary with driving style, load and conditions. Hybrid+ figures apply to both the SE and Trophy trims.

Day-to-day, the Hybrid+ switches automatically between EV, Hybrid and Engine Drive modes, drawing on the battery for low-speed town work and the petrol engine when motorway pace demands it. In EV mode, you get zero tailpipe emissions whilst driving, which matters in city centre clean-air zones even if the headline economy figure matters more to the monthly budget.
