Here are the first spy shots of the newly facelifted Porsche 911 Turbo convertible, which launches next year. The drop-top 997 Turbo will get a direct injection engine like the recently updated standard 997. It'll also benefit from Porsche¹s excellent PDK dual-clutch gearbox, which offers rapid, seamless shifts.It's likely that the 997 Turbo's new breed direct injection engine will offer 20-30bhp more than before, pushing peak power beyond 500bhp. But direct injection also means that the Turbo will be around 15 percent more economical than before.Like the facelifted 911 we've already driven, the Turbo will be marked out with LED tail lights and cosmetic changes to the front and rear spoiler. These subtle changes are most noticeable at the front, where the air intakes in the spoiler are different.
