The upcoming heritage model will reportedly pack the GT3's drivetrain as well.
Work continues on the next special edition Porsche 911, the upcoming 911 ST. The ST is part of a trio of special 911 models Porsche has been planning out for a few years now, comprised of the 911 Sport Classic, ST, and (maybe) an upcoming 911 RS. With the Sport Classic out of the way, Porsche has started work on this.
If you've missed our previous batch of 911 ST spy shots, the new P Car is a tribute to a 24-car run of 911 racers from the 1970s. At the time, the goal was to make the lightest 911 on sale. We'll have to wait and see if Porsche can pull off the same feat here.
Our spies report the new ST will be based on the existing GT3 Touring, which likely means a manual, just like the Sport Classic. The Touring's bodywork has been significantly modified, and now features a unique double-bubble roof, and some camo around the rear of the front fender hides some GT3 RS aero trickery. Additionally, these are said to be the same carbon fiber doors as the RS with some different handles fitted.
Unfortunately, much of the lightweighting can't be seen. We don't have x-ray specs, but there will be plenty of work going on under the metal to ensure this 911 is at least one of the lightest models in the lineup.
Given the ST's GT3 derivatives, we're expecting the powerplant to largely carry over to the new car. That'll mean a rear-mounted 4.0-liter naturally aspirated flat-six engine, with power outputs set somewhere around 502 horsepower and 346 lb-ft of torque.
Finally, we see another Porsche Heritage giveaway. On the engine cover, we see a small circular badge. This appears to be one not unlike the badge found on the Targa 4S Heritage Edition from a few years ago. There's no word yet on a debut, but we could see this new 911 ST within the next year or so.
