On the whole, the decisions it makes are good, and at dawn the next day as I chase NSX-mounted creative director Andy Franklin up the Grossglockner in the Porsche, it looks rapid and composed, and with twin electric motors vectoring front-wheel torque, it jets out of hairpins, leaving me working the balance, traction and grip to keep the 911R in touch. But that’s the fun, isn’t it? The Porsche acts on your inputs, requires you to manage the situation, to do the brainwork and master the car. And it does take some mastering. The rear-wheel steering is aggressive, a mid-corner lift will significantly change your trajectory, the ride is firm, the engine only does its best work above 5,000rpm. It takes effort, concentration and nerve to drive quickly. But the overall effect is magnified by the work you have to put in, so I get to the top, some 2,500 metres up, fizzing with energy and enthusiasm. My senses are on high alert, so even the scenery seems punchier, more magnificent in scale and grandeur after driving the 911R. And what scale, what grandeur. New vistas open, others close, it’s like Stanley Kubrick has directed what I’m seeing through the windscreen. It’s a visual bombardment, relentlessly stunning.
