Porsche has revealed the 911 Carrera GTS ahead of its official debut at the Paris show.
The new rear-wheel drive car gets a 23bhp boost over the standard Carrera S, and incorporates the wider track of the all-wheel drive 911s for improved handling.
The GTS also gets some minor design tweaks and the black 19-inch alloy wheels previously seen on the RS Spyder. The car is likely to prove the final evolution of the standard 911 as Porsche is due to replace the model next year.
Porsche has extracted the extra grunt from its 3.8-litre flat six engine by modifying the intake manifold and fitting a new sports exhaust. The additions push the GTS's output beyond 400bhp.
This boost in power means the car makes marginal gains in performance. Fitted with the optional seven-speed PDK gearbox, the new 911 will hit 62mph in 4.2 seconds - half a second quicker than the Carrera S. Stick with the six-speed manual and it's 0.1 second faster at 4.6 seconds.
As well as the wider rear necessary to incorporate the bigger track, the GTS also has a SportDesign front bumper with black spoiler edge, special side skirts and model-specific logos down the flanks.
Inside, Porsche has added black Alcantara to the centre sections of the sport seats and any surface the driver is likely to touch - the steering wheel, gear lever and handbrake.
While the GTS is behind the GT2 and GT3 in the Porsche pecking order, the new model will sit at the top of the conventional 911 Carrera range.
Following its debut in Paris the car will go on sale in the UK in December, priced from £76,758 for the Coupe and £83,493 for the Cabriolet.
