It'll be unveiled at this year's Beijing auto show later this month and is, as you'd imagine, a pretty good sign that Munich's going to give us a drop-top to join the i8 coupe. For those hard of memory, that's the 250km/h, 2L/100km sportster due to land in showrooms come 2014.
Underneath, there's an aluminium chassis with a lithium-ion battery buttered along its length, keeping the centre of gravity nice and low and achieving a 50:50 weight distribution. It's got the same plug-in powertrain as the coupe, too; a petro-electro melange of 95kW electric motor driving the front wheels and three-cylinder turbo petrol engine sending 165kW to the rears (that's 260kW in all).
All together, it makes 550Nm of torque, which gets it from 0-100km/h in 5.0 seconds and a tethered top speed of 250km/h. And it's claimed it can do 30km on the battery alone.
Unlike the 2L/100km coupe, the convertible only claims a piffling 2.5L/100km, but charge time on a domestic socket is impressive; BMW says it would be "less than two hours". It'll do 30km on EV power alone, and the batteries are charged up when you coast, cruise and stop.
There are, as you'd imagine, some spurious concepty add-ons. Also included are a pair of electric scooters housed under a transparent tailgate, a camera-based proactive collision warning feature, and the interior can be pre-warmed on a cold morning so it's all toasty and warm when you go to drive it.
