BMW’s open-top eco-supercar set for production?

BMW has released pictures of its i8 Spyder concept – the third version of its hybrid supercar that will be unveiled at the Beijing auto show later this month.

And stories suggest that the concept – capable of both 155mph and 90mpg – will reach production with an £80,000 price tag.

According to Autocar magazine sources at BMW say that the petrol-electric open-topper will go on sale in 2015.

If the car does reach showrooms, it will follow the i8 coupe, due on sale in 2014. The new concept is said to give more direct clues to the look of the production coupe, particularly the solid doors which replace transparent versions seen on the earlier concepts.

What form the roof structure of the Spyder will take has not yet been revealed but it is said to be a removable panel possibly in carbon fibre.

The car will use a lightweight structure of plastic reinforced with carbon fibre, as do all models in BMW’s eco-focused ‘i’ sub brand.

A 1.5-litre 219bhp three-cylinder turbo petrol engine – mounted in the middle of the car and driving the rear axles is combined with a 129bhp electric motor driving the front, giving four-wheel-drive capability.

The car will also be able to run powered by only the front or rear wheels, on petrol power alone or, for up to 19 miles, pure electric power.

It is said to be capable of five-second 0-60mph times with an electronically-limited 155mph top speed and up to 94mpg on the combined fuel economy cycle.
