Porsche Macan prototype 2018: first drive of refreshed SUV

And now you’re going to have to forgive me for being a little less statistically precise than usual, because at the time of writing the car does not actually exist, officially at least. The cars I drove were partly disguised and there is no press information, so what follows is based on unattributable gen gleaned from the various development drivers with whom I shared the cars.

Even so, I believe that what follows is absolutely what will be announced nearer the car’s official autumn unveiling, or as near as makes no difference.

The biggest changes come under the bonnet. Sadly, in line with Porsche policy the diesel Macans have gone (and rumours of a hybrid in this generation appear exaggerated) but the base Macan, the Macan S and Macan Turbo all receive considerable engineering upgrades.

The standard car retains its 2.0-litre turbo motor, but with its output raised from 248bhp in the current version to something close to the 300bhp the same engine generates in the likes of the VW Golf R.

Always something of a rarity in the UK, the performance upgrade this brings – along with the tax and fuel consumption benefits – are likely to make it a far more significant player in the UK market, especially now the strong selling diesels have gone.

The Macan S and Turbo both receive entirely new engines, though in the former case it might not look like it as it remains a 3.0-litre V6. But it’s the new-generation V6 from the Porsche Panamera that places its turbo in the vee for better emissions performance; its power is likely to rise from the current 335bhp to 355bhp with an appreciable additional slug of torque.

In short, it sits in the space occupied by the Macan GTS today. The replacement for that car will, in usual Porsche fashion, follow the rest of the range at a respectable distance.

The Turbo uses essentially the same engine but in 2.9-litre capacity (the reduction because it needs a beefed-up crank to cope with the extra power and therefore has a shorter stroke). It will increase power from the 394bhp of the current 3.6-litre motor to 434bhp, which just happens to be the same output as today’s car when carrying the optional Performance Pack. That hits 62mph in 4.4sec and I’d not expect the new one to be significantly different.
