Porsche 964 911 Turbo S

Though not a GT2 by name, the 964 Turbo S born of the early-‘90s was a GT2 by nature.

With a 280kW/490Nm turbocharged 3.3-litre flat six pulling a 1290kg car, the Turbo S could launch to 100km/h in 4.7 seconds, and then onto a blistering (at the time, but it’s even quick now) 290km/h.

It’s in this list because it was as ground-breaking (some might argue more so) in terms of potential as the GT2s it preceded.

One of these rarities sold for £1,848,000 (or $3,133,000 AUD) at an RM Sotheby’s auction last year, but that one only had 12,730km on the clock after two decades.

Developed as a road car, the water-cooled 3.6-litre flat six peaked at 355kW and dipped below 4.0sec to 100km/h.

Adding variable geometry turbos upped the kilowatt count to 390, it topped 200mp/h and lapped the Nurburgring in 7min 32sec.

That alone should tell you what you need to know about the GT2.

With 456kW/700Nm it was the most powerful 911 ever built and the combination of turbo lag and two-wheel drive meant it could be hard work even for experienced hands.

The extra power and 70kg diet meant it could hit 100km/h in just 3.5sec on its way to a 330km/h top speed.

During development its code name was 727, a reference to the Nissan GT-R’s then-benchmark 7min27sec Nurburgring lap time, a mark the GT2 RS shaved nine seconds off.

Just 500 were built and price tags now approach A$1million.

With 515kW/750Nm (a total 59kW/50Nm over its predecessor), the current RS is claimed to be able to pull its 1470kg mass to 100 km/h in 2.8 seconds.
