Porsche has already confirmed a new model debut for next week’s 2011 Detroit Auto Show, with one official boastfully describing it as something “spectacular”.  While the automaker has several brand new models in the pipeline--the production version of last year’s awesome 918 Spyder Concept, a new entry-level sports car and compact SUV--the release of these models is still several years away, at the earliest.

Instead, we’re more likely to see a model previewed not for general sale but rather one aimed at well-heeled racing enthusiasts and professional motorsport teams.

According to AutoBild, Porsche is expected to preview a new customer race car in the form of a 918 Coupe. Like the Audi R8 LMS and Mercedes-Benz SLS AMG GT3, the 918 Coupe will be strictly for track use and come with a race-bred V-8 engine.

It will ride on the new mid-engine platform being developed for the upcoming production 918 Spyder due for sale in 2014. Importantly, it won’t feature the 918 Spyder’s advanced hybrid drivetrain but rather a more conventional naturally aspirated mill. Peak output is expected to come in at around the 600 horsepower mark and pricing will range into the hundreds of thousands of dollars.

If you can’t make it to next week’s Detroit event, you can catch a live stream of the unveiling at Porsche's site (not yet live).
