The MG 3 will be priced between £8399 and £9999 when it goes on sale in September.
The four-strong model range features LED daytime running lights and hill-hold as standard, alongside six airbags, ESP, corner brake control and traction control. All models, bar the entry-level car, feature DAB as standard.
MG is making a range of personalisation options available, which from launch will include 'graphics packs', contrasting door mirrors and interior 'finisher' colour packs, which include colour-coordinated keys.
The entry point to the range is the £8399 3Time. The £9299 3Form adds air-con and Bluetooth, while the £9549 3Form Sport adds a bodykit and 16in alloy wheels. The range-topping 3Style, priced at £9999, also features cruise control, parking sensors and automatic headlights and wipers.
The supermini is offered with a 105bhp petrol engine, mated to a five-speed gearbox. MG says it predicts a 4E insurance rating, which it claims is half that of its rivals.
