I loved the GTS and the way it tackled those surfaces, somehow finding the perfect balance: not so stiff that it was deflected by secondary imperfections yet sufficiently controlled to maintain exemplary primary ride control. It does wonders for your confidence. I could have driven it all day and, were there not a shockingly yellow GT4 to try as well, would have done.
Settling into the GT4, you notice first that those optional buckets are brilliant, but the engine sounds pretty much the same, while the steering is curiously a touch lighter as you come off-centre, despite the stickier, fractionally wider front tyres. It’s not better or worse; I just thought I should point it out. The ride, however, is inferior and, with it being more stiffly sprung in both spring rate and sidewall, it would be a surprise were it not. On this difficult road, there’s a restlessness to it that you just don’t get in the GTS. It feels a little more connected to the surface but not enough to offset what it loses in ride compliancy for those wanting a thrilling yet still daily-drivable car.
But what if you’re not? What if you simply want the best-driving Porsche available for a five-digit sum? Actually, I might direct you towards the GTS again. It’s so quick, so easy and so reassuring – even on dry roads, let alone wet surfaces to which its tyres would be far better suited than those of the GT4 – that it would probably be the better car for most people most of the time.
Yet there’s something else here. No GT Porsche is for most people. Most people who buy a Porsche buy an SUV. And for the right person – the person who really likes to put a car through its paces and who ranks the resulting experience above all – the GT4 suddenly comes into its own. Drive both cars hard and you’ll find the GT4 changes direction better, has more traction (although the GTS is hardly deficient), far better brake feel on its optional discs (which surprised me, because I always prefer the feel of iron rotors on 911s) and, when you’re really pressing on, where the feel for the road is all, it’s just more of what you want a true driver’s car to be.
Bear in mind, too, that we took neither car to a track, an environment in which the GT4’s small on-road dynamic advantage over the GTS would likely only widen further.
