The concept is due to be shown at the Volkswagen Group's evening gala event ahead of the show.
Volkswagen's show car indicates the production version of the Golf GTI is not far away, with all the GTI's traditional cues applied to the seventh-generation VW Golf that also makes its public debut in Paris.
The horizontal grille gains that trademark red line, and the alloy wheels are of a more dramatic design than those found on regular Golfs - though this time there's a five-blade design compared with the telephone-dial-style alloys of the previous two Golf GTIs.
The rear end features twin outboard tailpipes, releasing exhaust gases from an engine that leaked details also indicate the new Volkswagen Golf GTI will be powered by a detuned version of the new Audi A3's 2.0-litre turbocharged four-cylinder.
With 160kW, there's a 5kW power increase over the outgoing GTI, while torque is set to increase to 350Nm.
That's good enough to cut a few tenths from the Golf GTI's 0-100km/h acceleration capabilities - to 6.6 seconds.
Fuel efficiency will also improve for the hot Golf that, like regular versions, is lighter than its predecessor.
The interior also adopts the now-familiar GTi cues: flat-bottomed steering wheel, red stitching and the tartan seats.
CarAdvice will be at the unveiling of the concept and will bring you all the official images and details of the Volkswagen Golf GTI show car once it's revealed.
