This is the i8 Spyder, the latest concept from BMW's new i sub-brand. Due to be shown at the Beijing motor show later this month, the latest i8 is the third version of a concept that started off at the 2009 Frankfurt show as the Vision Efficient Dynamics concept.
It then morphed into the i8 coupe for the 2011 Frankfurt show, before becoming this, the Spyder version - the closest yet to the coupe that's expected to make production in a couple of years time.
Among the key differences between the latest concept and its predecessors (apart from the absence of a roof) are new scissor-style doors (the glass ones of the other concepts have sadly gone), a blanked-off grille and subtly softer exterior surfacing.
Oh, and unlike the original i8 concept, the new car is a two-seater and so has a shorter wheelbase.
It's still a plug-in petrol-electric hybrid, however, with a 223hp 1.5-litre three-cylinder turbo petrol motor (coming to a 3 Series near you in some form or other, we would be willing to bet) powering the rear wheels and a 131hp electric motor sending drive to the front axle.
Together that makes for 354hp, 0-62mph in 5.0 seconds and a 155mph top speed, along with 90mpg-plus. Sounds like an appealing combination to us...
