Which Porsche 911 GT3 is your favourite?

The 911 GT3 arrived in 1999. One of the first production cars to lap the ‘Ring in under eight minutes (says Porsche), it got a 3.6-litre N/A six-cylinder engine that made just 360bhp. By today’s standards, not very much at all. It did rev to 7,800rpm though, and was paired with a most excellent six-speed manual gearbox carried over from the 993-generation 911 GT2. All-in, it weighed 1,350kg. This is nothing.

Four years later the GT3 was updated, and offered in the USA for the first time. Now with more power – 381bhp – and an even higher redline (8,200rpm), it was still based on the 996-shape 911, but was more serious an item than ever. 0-60mph was dealt with in 4.3 seconds, and you’d see 190mph. This GT3 also marked the arrival of carbon-ceramic brakes – they were a rather pricey option.

The 997-era GT3 was revealed in 2006. Though it was still powered by an N/A 3.6, power was increased to over 400bhp, and the redline to 8,400rpm. Porsche ‘Active Suspension Management’ was now fitted as standard, and the chassis honed to near-perfection.

The 997 was updated in 2010, so the GT3 was too. Now 3.8 litres in capacity, the flat-six gave 435bhp and 317 lb ft of torque, meaning 0 to 60 mph was dealt with in 4.0 seconds flat, and you could run on to a top track speed of 194mph. The redline, meanwhile, climbed yet higher to an ear-damaging 8,500rpm. ‘Ring time? You’re looking at 7 minutes and 40 seconds. Serious stuff.

Things changed for the 991. We waved goodbye to the manual gearbox and hello to Porsche’s admittedly excellent PDK dual-clutch auto, which was fitted as standard. There wasn’t even the option of a manual (at first…). But no matter – this was a tremendous car. As, indeed, all GT3s are. 475bhp, 9,000rpm redline, 0-60mph in 3.3 seconds (thanks PDK) and all-wheel steering meant the ‘Ring time fell to 7 minutes and 25 seconds.

The updated 991.2 GT3 did it in 7 minutes, 12.7 seconds. Around 45 seconds quicker than the first-ever GT3. Progress. Its 4.0-litre engine, still N/A, makes 500bhp and allows for a 198mph top speed. The manual gearbox is back, too, and for the first time there's a 'Touring' version that does without the massive wing. Looks ace, doesn't it?

Now we arrive at the brand new 992 GT3. And in the least surprising news ever, it's really bloody good. Read why by clicking on these blue words. Question is, would you have one over and above an (also excellent) older GT3?
