BMW has announced details of its new flagship M Sport model for its 1 and 3-Series.

The 3-Series M Sport cars come with a more aerodynamic bodykit, stiffer and lowered suspension and 18-inch alloys as standard.

Inside the cars will be sportier seats and an M leather steering wheel and gear lever.

Prices start at £28,330 for the 320i M Sport Coupe rising to £40,250 for the top-end 335i M Sport Convertible.

The range-topping 130i M also gets a boost with a limited edition Sport model.

Featuring a 3-litre engine producing 265bhp, the 155mph M Sport Limited Edition will be available in carbon metallic black with a lemon-coloured leather interior.

The scorching-hot hatch will also feature 18-inch World Touring Car Championship-style alloy wheels, chrome exterior surrounding the windows and a bespoke start/stop button.

Only 160 of the limited edition 130i M Sport will be available with an on-the-road price of £30,270.

Both M Sport ranges will be available from April.
