As for the R8 Spyder, a spokesman for Audi previously confirmed that it has been delayed to allow time for sales of the V10 hard-top to eventually die down. The Audi rep also confirmed that the Spyder will feature a full convertible soft-top roof instead of a smaller targa set-up, which was the preferred choice of engineers back in Germany.
Other major changes for the car that are expected to make it to production will be additional air intakes located behind the seats, as well as a pair of safety roll-over bars. Sadly, the R8’s trademark aluminum side blades have been removed. The placement of the fuel filler cap will also be changed due to the missing rear pillars, while changes under the sheet metal will likely include extra chassis strengthening.
