Photos of Porsche’s new 911 GT3 RS based on the 991-series 911 have already leaked onto the web ahead of the car’s expected debut at the 2015 Geneva Motor Show in a week’s time. Now some of the car’s specs have also leaked.

According to the leaked information, obtained by Motor Trend, the new GT3 RS will be powered by a 4.0-liter flat-six naturally-aspirated to the tune of 500 horsepower and 339 pound-feet of torque. This suggests the engine is related to the 4.0-liter unit fitted to the 997-series 911 GT3 RS 4.0 special edition, which featured identical numbers.

However, according to a previous report, the engine fitted to the new GT3 RS is an all-new unit and is expected to appear in other 911 variants once the current model undergoes its mid-cycle update later this year. The leaked information says the engine will feature all-aluminum construction, direct fuel injection and an 8,800 rpm redline.

There won’t be a manual, as many had hoped, with Porsche instead sticking with its seven-speed PDK dual-clutch unit. Other tidbits revealed include the addition of a multi-link rear axle with an integrated auxiliary spring, anti-roll bar, and chassis bearings with ball joints at the rear.

The wheels will reportedly measure 21x12.5 inches at the rear, with a 20x9.5-inch set used at the front. These will sit within pumped fenders made from carbon fiber. The roof will be magnesium and the rear and side windows will be polycarbonate, all aimed at helping reduce weight.

For the interior, look for carbon fiber seat frames, a unique steering wheel lined in Alcantara, silver accents including for the seatbelts, and a Pit Speed button that limits the vehicle speed to a pre-determined level for when entering the pits at your local track. Some of the options are said to be a roll cage, six-point racing harness, a HANS brace connector for the driver, and a fire extinguisher.
