This is the new Porsche 911 GT3 RS. We'll give you a moment to let that sink in.

Now for even more good news. This is not merely a GT3 with a bigger wing. This is really something special: bespoke new 4.0-litre flat six engine, magnesium roof, carbon fibre bonnet and boot lid, body based on the 911 Turbo, wider tracks, more aero, lighter weight, staggering Nurburgring lap time. And, contrary to rumours, it's very much not turbocharged.

This is Porsche showing that while it might be able to do tech with the 918 Spyder, it can also do pure motorsport cars. So let's ignore the fact the GT3 RS does 22.2mpg on the combined cycle and instead focus on some exciting numbers.

493bhp is a good place to start, also 354lb ft. Now on paper these are not significant rises over the standard 911 GT3 (469bhp and 325lb ft), but the increase in displacement of this direct injection motor from 3.8 litres shows Porsche's commitment to engineering, its desire to endow the RS with more torque and - we'd guess - better driveability at low engine speeds. Also, it's now the same displacement as the old 997-gen GT3 RS 4.0. Cool.

Yes, it drives through a PDK gearbox. No manual. No massive surprise if we're honest. And besides if you want a manual you now have the Cayman GT4 to keep you happy.

A couple of new functions have been included in the double-clutch gearbox's software - pull both paddles and you get neutral, and there's a pit lane speed limiter, too. More importantly, it helps endow the GT3 RS with a 0-62mph time of 3.3 seconds, with 0-124mph taking just 10.9 seconds.

Total weight saving over the standard 991-gen GT3 is only 10kg, but Porsche is at pains to point out that it's the reduction in the centre of gravity that's most important, hence the focus on reducing weight higher up on the car with the adoption of a magnesium roof and carbon panels for the nose and engine cover.

The indentation in the bonnet is a nod to historic 911s, while the slats over the front arches are claimed to increase front axle downforce, balancing out the additional aero created at the back by that outrageous new wing.

The suspension has been retuned, and the wider 911 Turbo body means fatter track widths front and rear, which, teamed with wider tyres, helps increase grip and roll stability.

Throw this all together and the end result is that the new 911 GT3 RS has the ability to get itself around the Nurburgring Nordschliefe in 7 minutes 20 seconds. Yep, that's 9 seconds faster than the mighty Carrera GT managed, 12 seconds faster than the standard GT3.

It costs £131,296, which includes carbon fibre sports seats based on those in the 918 Spyder and the Club Sport pack with bolted-in roll cage and six-point harness.

Also standard are bi-xenon headlights, 20-inch front and 21-inch rear wheels, PASM, PTV, PSM and, we're sure, other initials. Sport Chrono is optional, but probably worth having as it includes a GPS lap timer and the ability to link to your smartphone. You know, so's you can compare data with your GT3 RS driving mates. Nothing competitive in that...

But really, just how much do you want a GT3 RS? More than a Carrera GT? More than a 918 Spyder? More than, well, anything?
