It’s no secret that the Porsche 911 is the money maker in the Porsche lineup, it’s the car that the German brand is known for, and it’s the reason there are no less than twenty-seven 911 models listed on the Porsche website for the SA region with a few extra special editions on the European site. There’s pretty much a Porsche for every taste, not so much for every budget though seeing as the entry-level model here in SA starts at R2,158,000, which should set you back at least R40,000 a month if you bought it like a conventional car. When the Cayman was released, it was the smaller and much less powerful sibling to the 911, and it also cost a fair bit less. Some called it the poor man’s Porsche but even if that was the case, it’s still out of reach of this here SXdrv scribe. As the Cayman became more popular, Porsche started putting a lot more R&D into the platform, so much so that the current range-topping Cayman is now regarded by many in the automotive world as one of the best Porsches you can buy. It did help that the men in white coats at Porsche managed to shoehorn the 911 GT3’s engine into the smaller car. With all the right tweaking to the suspension and the programming for the transmission the end result is a properly fast car in a straight line and on a circuit too. You can find loads of reviews and videos online comparing the two, and many from some of the most respected names in the game.

This latest video comes from the Carwow team and sees Mat Watson and Yianni Charalambous from Yiannimize pitch these two range-topping Porsches against each other. Yianni was on hand to pilot the blue 911 GT3, which admittedly looks better in different paint than what you see here, but that’s a subjective choice. If we chose a blue for a 911, it would be Miami Blue. The GT3 sees fitment of a normally-aspirated flat-6 that makes more power than it should considering there are no extra power adders in the mix. It’s rated at a very healthy 386 kW with 470 Nm of torque. Power goes to the rear wheels only via a 7-speed dual-clutch transmission and it can hit 100 km/h in 3.2 seconds and has a top speed of 296 km/h. These things start at R4,858,000 here in SA. Watson pilots the Cayman GT4 RS, which features the same normally aspirated 4.0 litre flat-6 from the GT3, but the power has been toned down ever so slightly. In this setup, the car creates 368 kW with 450 Nm of torque and also has a 7-speed DCT transmission. This one can hit 100 km/h in 3.6 seconds, but oddly has a better top end up at 315 km/h. This one in SA starts at R3,024,000 - which is already looking like a bargain. These slight differences in performance are probably down to weight, the 911 GT3 tips the scales at 1,435 kg and the Cayman at 1,415 kg. Any proper testing of these cars should be on a circuit, that’s a given, but it is cool seeing them go head to head in a drag race.

Take a look at the YouTube video that pits two of the best modern Porsches in existence today against each other. Representing the 911 line is the 911 GT3, widely regarded as one of the best ever created, and representing the Cayman line is the GT4 RS, the smaller and lighter sibling with the same ridiculously powerful powerplant: Porsche GT4 RS v GT3: DRAG RACE | carwow
