MINI Spirit returns

British legend's big plans for new small car are exclusively revealed

It’s MINI’s biggest ever secret – and autoexpress.co.uk has all the details.

We’ve uncovered a bold plan by the British car maker to develop a new family of city cars, including a zero emission flagship powered by an advanced electric engine.

Though exact details remain scarce, it’s believed that the ultra efficient model line up will also offer drivers fuel sipping petrol engines as MINI owner BMW seeks to build an army of green machines aimed at beating tough legislation on CO2 and other gas emissions due in 2012.

Set to hit the road as early as 2011, it’s been confirmed to Auto Express that the top-secret machine is being developed alongside two new models from a joint venture between Fiat and BMW that’s tipped to mark the return of the famous BMW Isetta and Topolino nameplates

Aimed at a fast growing family of soon to be launched rivals – including Volkswagen’s Up! and a new family of small electric cars from French maker Reanult, MINI is promising to return to its roots with a lightweight model the promises to be every bit as innovative as the 1959 original.

It’s said to be no accident that MINI has chosen its 50th year to begin to develop such a ground breaking new model.

With its engine in back, petrol models will offer four seats and easy to access four door cabin. Individual chairs for driver and passenger will ensure safety is first rate, while the car’s wheel at each corner stance promises to ensure the car feels secure and stable on the road.

Plenty of effort is being poured in to ensuring that visibility is as good as it can possibly be with a large glass area set to ensure that the car is as easy as possible to drive on congested city roads.

Also under consideration is lightweight, tough plastic bodywork, like that fitted to the Mercedes Smart, while the car’s chassis will mix aluminium and composite materials like carbon fibre to deliver enormous strength and light weight.

Electric models could further improve the car’s interior space by locating the batteries in a thin sandwich under the car, and placing electric motors in all four wheels.

Technology to propel this version of the machine is reportedly already well advanced, and has already been publicly trialled in a prototype MINI called the E. This machine, which uses a battery and engine set up similar to that developed by American sportscar firm Tesla is set to be made available in small numbers in both the USA and Germany.

There’s no word on pricing for the newcomer, but given the advanced technology it’s expected to offer, it’s likely that flagship models will cost at least £20,000. A concept paving the way to full production is tipped to make an appearance at this year’s Frankfurt Motor Show.

The 100mpg fuel busters!

BMW and Fiat are joining forces to bring a revolution in the market – with a pair of ‘bubble’ cars which promise world-beating economy and ultra-low CO2 emissions...

Two of the most important new cars ever are about to ‘bubble’ to the surface – and in a world exclusive head-to-head, Auto Express has brought them together for the first time!

These are the clearest illustrations yet of BMW’s new Isetta and its sister, the Fiat Topolino. They are the result of a new deal between the two firms, which will also be extended to include next-generation versions of the MINI and Alfa Romeo MiTo.

The Isetta and Topolino are crucial to BMW and Fiat’s attempts to reduce the overall CO2 emissions of their ranges – but they will also offer buyers 100mpg fuel returns! Reviving a name not seen since the bubble car of the Fifties, the Isetta will take BMW into a new sector of the motoring market.

It will be joined by the Fiat Topolino – which we featured in Issue 1,013. Both machines will offer incredible fuel consumption and low emissions, as well as tiny dimensions, and rival the imminent VW up! and Toyota iQ.

The Isetta will be hugely important, because it will help BMW comply with the European Commission’s plans to impose an average 120g/km limit on the model ranges of all firms selling cars across the Continent by 2012. And, as there are plans for an electric version, it would also enable the manufacturer to meet California’s upcoming zero-emissions vehicle legislation.

As you can see from our artist’s impression, the Isetta harks back to the original bubble car shape. But it has been given a modern reworking by the design team, with the addition of some BMW-style chunkiness. The body is made up of simple panels, likely to be fashioned from plastic to save weight and help resist parking dings.

Meanwhile, the Topolino gets a retro look inspired by the 500, with a cheeky front end featuring a smooth nose and large headlights. Under the skin
of both models lies an all-new platform that places the engine in the rear and sends drive to the back wheels.

With an electric-only Isetta some way off, small-capacity petrol and diesel engines will feature initially. And as Fiat is using a new 900cc two-cylinder petrol motor in the Topolino, the Isetta could benefit from the same unit.

The new powerplant was previewed in Fiat’s Panda Aria concept at last September’s Frankfurt Motor Show, and it arrives in dealers under the bonnet of the 500 later this year. While two outputs will be offered in this car – a 105bhp turbo and a normally aspirated 65bhp unit – it will be the latter that powers the Topolino.

Twin-clutch semi-automatic gearboxes are likely to be used by both models, as is a stop-start set-up which switches off the engine when the car
is stationary in heavy traffic. Combine this technology with a lightweight body, and the newcomers will be incredibly efficient. Expect combined fuel economy of 100mpg and CO2 emissions of less than 90g/km.

The interior layout is still up for debate, but there is likely to be enough room for three occupants with an occasional fourth seat, allowing owners
to juggle luggage capacity with passenger space.

It will be interesting to see if BMW and Fiat can make the rear-engined, rear-wheel-drive layout work efficiently. An insider at VW recently told Auto Express that a similar mechanical layout in the up! is being ditched in favour of a front-engined, front-wheel drive format, after it was found that the layout was too costly to develop and made the car unstable in cross winds.

Although official production dates have yet to be decided, the Isetta and Topolino are set to arrive some time in 2010.
