An entirely slain-outside Porsche 911 test mule caught testing. At first blush, it might not seem any different in the deluge of present-generation 911 models, but look carefully and it is given by the details away as a brand new GTS.

The GTS's unexpected look only two years into the life cycle of the 991, joined with the recent glut of 911 form introductions of Porsche, suggests patience is being abandoned by the brand and spitting out 911 versions as they are developed. Formerly, Porsche would space out the introductions of its significant amount of 911 versions over the run of the automobile.

This type of strategy is probably a matter of cash: Why compel customers to await the special 911 or GTS? The automobiles will be bought by brand loyalists regardless offering them up earlier simply fills the coffers of Porsche that much more rapidly. As for enthusiasts of naturally aspirated Porsche functionality, its character is also reprised by the GTS as the zenith of non-turbo, non-pseudo-racecar 911-ness.

Stage: It's difficult to tell, but the GTS image shot by our spy photographers seems to once again use the all-wheel-drive Carrera 4's broader body and track. The last-gen GTS was the lone way to couple those broad hips with back-drive, although all-wheel drive was accessible, also. Otherwise, suspension and the structure should reflect 991 menu that is normal, albeit with some more solid suspenders for improved management and more sportiness. A couple of intriguing details will place the GTS apart from the 911 bunch, including exceptional engine-cover venting, extractor ports behind each back wheel, closely bunched double exhaust exits (every other 911 has broad-place exits except the GT3, which gets two centre-exit conduits), and center-lock wheels, the same as the last GTS. A cabriolet version is all but ensured, although it isn't pictured here; the outgoing GTS was offered by Porsche in type that was topless.

Powertrain: Not a lover of turbos? We anticipate the 911 GTS will function as a pariah -revving aspiration that is natural, and better still, it should offer a manual transmission--something the more strong but automatic- GT3 can not fit. Porsche probably will stick with the Carrera S's 3.8-liter flat six engine, but like the preceding GTS's factory, it should be massaged for somewhat more power.

Estimated Arrival and Cost: The GTS should arrive in showrooms following an auto show introduction in the autumn, toward the ending of the year.
