The drop-top version of the BMW i8 was spotted once again and this time our spies were able to get a closer look at the soon-to-be-released convertible.

To be officially called the i8 Spyder, the prototype almost has an identical design with the hardtop. The only major difference can be found at the rear where BMW gave the i8 Spyder a pair of buttresses, replacing the rear windshield. As for the front fascia, it appears the sports hybrid will get a new hood, along with a slightly altered set of headlights and front grill.

As the car is still heavily camouflaged, we're not entirely sure if BMW did some alterations on the doors, side skirts and body panels. What is clear, however, is that the i8 Spyder will use a soft-top, not a folding metal roof. This could mean that the upcoming Spyder will have conventional doors instead of the standard gullwing doors.

The 1.5-liter three-cylinder TwinPower Turbo hybrid engine will likely be carried-over to the i8 Spyder though it may get a slight bump in power. Currently, the powertrain cranks out 362 PS and 570 Nm of torque.

There is no clear timeline yet as to when BMW will officially launch the i8 Spyder.
