We're just getting settled with the latest update to the Porsche 911 (997) Carrera, but we also know the 998 is just around the corner. We've already seen the spy shot of the future Turbo version out for a little testing, and now we see the convertible testing to make sure the new top can handle the cold stuff.

What's really great from this spy shot is the shape of the new convertible roof. The next 911 Cabriolet may use a lower and flatter roof, which is reminiscent of the 356 Speedster. How much will this drop-top take from the classic Porsche design? We should know by 2011 when this new 911 hits the streets.
