WATCH: New Porsche Taycan Sport Turismo Hits The Nurburgring In Full Stealth Mode

Development of the facelifted Porsche Taycan range is continuing a pace. While the Taycan sedan, Cross Turismo, and a new mystery variant were spotted before, it's time for the wagon - or Sport Turismo model - to undertake public testing. Even better, the long-roof model was caught stretching its legs at the Nurburgring for some stealthy, hot laps, courtesy of CarSpyMedia.

As expected, the facelifted Porsche Taycan Sport Turismo will adopt the subtle updates on the sedan and Cross Turismo we've seen before. The updated headlight clusters are prominent, particularly the four bars of daytime running lights. This reflects the ones seen on the refreshed Cayenne SUV.

One particular point of intrigue that we've seen before and we're seeing again is the camouflaged front bumpers, specifically the odd indentations hidden underneath the wraps. They look like fog lights, which will be replacing the teardrop-shaped vents of the outgoing model if it remains true in the production model. At the rear, the changes are difficult to discern. The full-width, narrow LED strip remains in the prototype, though, so it appears that it won't go away in the facelifted version.

Meanwhile, our previous spy shots indicate that a new, hotter Taycan could be underway. Reportedly called the Turbo GT, the spruced-up model was spotted testing before with a huge rear wing, modified side skirts, and a different set of wheels. A similar Taycan variant was spotted last year with a roll cage and Recaro racing seats, hinting that the high-performance model will be highly capable at the track.
