With a top end output of over 404kW when unrestricted, it beats its RS sibling in wattage by 21kW while also being more focused in just about every other aspect.
Actual power and weight of the car will vary depending on the BoP (balance of performance) restrictions, but an example of restricted weight for the previous GT3 R was 1250kg in the FIA GT World Cup race in Macau, 2017.
In addition, engine power is usually pared back to keep its power-to-weight ratio in line with other cars.
The GT3 R is able to be so much lighter than the road car (the current GT3 RS weighs 1430kg) through extensive use of an aluminium-steel composite, carbon fibre-reinforced plastic, and polycarbonate for the windows.
A dry-sump 4.0-litre boxer six is found, as you’d expect, at the GT3 R’s rear, hooked up to a 6-speed sequential ‘box.
The powerplant is closely related to the version used in the 911 GT3 RS, Porsche says, as is the R’s aerodynamic setup.
Review: Porsche 911 R
While the wing on the road car is hardly subtle, the race car’s 1.9-metre-wide adjustable wing tops it for spectacle.
The wing, as with most of the panels and doors, is made from CFRP, and works with the front fairing and splitter to create a balance of downforce.
Porsche says its brakes have also been upgraded, with better control over the ABS system and 6-pistons at the front on 390mm discs, and fours at the rear on 370mm discs.
It has a base price of 459,000 euros before any local taxes, meaning it’ll likely set Aussie buyers back well into over the AUD$1m mark, and putting it in firm contention for the title of most expensive GT3 racer available.
