Mark Webber tips into turn one at Phillip Island with all the fuss of someone stirring a cup of tea. Except, of course, we’re doing somewhere north of 250km/h.

We’re sitting next to him as he’s flogging a new 991 Turbo. He smashes the brakes into turn one, the car wriggles on its tyres a little bit before settling, at which point Webber’s foot is again buried in the firewall carpet, a throttle pedal beneath it.

We’re very lucky to be riding alongside Webber for the launch of the new 911 Turbo and Turbo S, where he’s showing us what it can do. Originally we thought we’d be reporting on the 911 GT3 for you. But it’s had a few, err, issues (see page 12).

That’s indeed a lot of dough. Over the Turbo you get active sway bars, special LED headlights, carbon ceramic brakes and centre-lock 20-inch wheels. And in case the $359,800 Turbo’s 383kW/660Nm and 0-100km/h time of 3.4 seconds didn’t quite scratch your itch, Porsche adds more chilli for the S.

For $441,300, the 3.8-litre twin-turbo flat-six is wound to 412kW/750Nm (on overboost) and the rev ceiling raised from 7000 to 7200rpm. The 0-100km/h time lowers to 3.1sec and 0-200km/h drops from 11.1sec to 10.3sec.

Particularly on track. Of course, the throttle pedal feels like it’s connected to the nozzles of the Saturn V rocket. The brakes seem to have limitless bite the harder you squeeze them. The all-wheel steering unlocks new levels of high-speed stability but also low-speed agility. You step out of a 911 Turbo after a few laps of the Island able to mumble words only one at a time.
