The entry-level Mini, making its debut at this week’s Geneva Motor Show, will be called One.

The 90bhp range starter and the 115bhp Cooper model both go on sale in the UK on 7 July. Sales in other markets commence later in the year followed by the U.S. launch in 2002.

The four cylinder, 16-valve, 1.6-litre engine, produced in Brazil in a joint venture with Chrysler, gives the One a 0-62mph (0-100km/h) acceleration time of 10.9 seconds and a top speed of 115mph. The Cooper has 115bhp for a top speed of 125mph and 0-62mph in 9.2 seconds.

Front and side airbags, disc brakes with anti-lock, rear screen wiper, chrome headlight rims and door handles, remote control central locking, six-speaker sound system and electric windows and mirrors are standard on all Minis.

The Cooper version adds 15″ aluminium wheels in silver or white, a black or white painted roof with matching side mirrors, a tyre pressure warning system, and chrome radiator grille, exhaust and light rims.

Options include side curtain airbags, a panorama sunroof, bonnet stripes to match the roof, leather trim, Steptronic automatic transmission, multifunction steering wheel, rain sensor, satellite navigation, dynamic stability control and xenon head lights.

BMW will also offer three option packages called Salt, Pepper and CHILI, offering combinations of features at attractive prices – typically a 30 per cent saving over the cost of adding the items individually.

UK press reports say that the Mini will use the Chrysler engine until 2007, when it will be replaced by a new BMW unit built at the Hams Hall factory in England.

Toyota is expected to provide the engine for a diesel version of the new Mini, essential if the model is to be a success in Europe. The 1.5-litre unit will be similar to the one used in the Japanese company’s Yaris model.
