An all-new Mazda3 range, plus details of Volkswagen’s new Golf Plus and Audi’s A5 Cabriolet, were revealed at the Bologna Motor Show this week.

The new Mazda3 range, which will come to the UK in April in four-door saloon and five-door hatchback guises, will offer a range of engines including, for the first time, a sub-120g/km of CO2 unit in the form of the 1.6-litre diesel version.

Following on from the launch of the new Golf, Volkswagen revealed the Golf Plus at the show.

The taller, more MPV-ish Golf will go on sale next spring with the range of engines offered in the standard Golf hatchback.

Elsewhere, Audi debuted the A5 Cabriolet to replace the ageing A4 version.

The Convertible goes on sale next summer with a choice of front and four-wheel drive, manual and automatic gearboxes, plus petrol and diesel engines.

Unlike rival BMW, which has opted for a folding metal roof on the 3 Series, Audi is sticking with a fabric roof.

Continuing the soft-top theme, MINI has revealed details of its new Convertible.

Due on sale in March, the Cooper and Cooper S models will be based on the Mk II MINI hatchback.

Prices will start at £15,995 for the Cooper and £18,995 for the more powerful S.

• Fiat is extending its Bravo range with a new diesel engine. The 165bhp 2.0 MultiJet will be offered in Sport and Dynamic trim, with prices starting at £16,855. The engine returns 53mpg combined and CO2 emissions of 139g/km.
