Cutaway Porsche 997 Turbo

Yea okay, it’s just another 997 Turbo sitting on the showroom floor. No biggie, right?

Wrong. This cutaway 997 Turbo is currently on a world tour of Porsche dealerships and motor shows, and is making a short stopover in Adelaide. It provides a fascinating chance to get up close and literally see what makes up the 911 legend.

The biggest thing that strikes you is the craftsmanship that goes into these cars. For sure, they are mass produced these days, but they possess the same precision that makes old 911’s so reliable and durable. Anyone who’s ever seen under the skin of a modern Ferrari or Lamborghini would no doubt be surprised at how home built they look. 

And I guess the quality shows. I really could picture driving a 911 Turbo to work every day and on the track every weekend, but most people wouldn’t consider doing the same in an F430 or Gallardo.

There’s really not a lot of material separating the 370hp, 3.8 twin turbo flat 6 from the quiet confines of the passenger compartment.

And the passenger compartment is carefully placed around the mechanical package. The large transmission tunnel divides the rear seats, and houses the six speed manual gearbox…

… and prop shaft running to the front transfer case, and driveshafts out to the front wheels. The 4WD system features Porsche Traction Management, which can send power to the front or rear axles to counter under or oversteer. It adds a whole lot of grip, but it also adds a whole lot of weight.

It’s in photos like this where you can see why these cars are expensive – just think of the cost and complexity involved in manufacturing those cast aluminium suspension arms, and that’s just one part of thousands.

I really love looking at the packaging of the 911 Turbo, and how they’ve managed to pack so much technology into such a small place. Just look at the intercooler flow. The cool air flows into these scoops just behind the doors (or where there are usually doors…)

… and flows through that big black plastic path over the rear wheel, and down into the intercooler. Once through, it the warm air then exits through a vent in the bumper just behind the rear wheel.

And it’s even more impressive when you see that there is only about a 3 inch pipe from the exhaust mounted turbo to the intercooler, and then short routing from the top of the intercoolers into the centrally mounted intake. Keeping the charge tracks short means minimal lag, something these modern Porsche turbos are famous for.

Even the front mounted fuel tank has been cut away, and is specially shaped to fit in around the front transfer case.

You can see how modern cars are designed and built with safety in mind. This is a perfect cross section of where the windscreen meets the roof – it almost looks like an integrated roll cage made from perfectly formed sheet metal.

My German is non-existent and Google translate is a little vague, but this roughly translates as “Model built through technical vocational education and the press department of Dr. Ing. h. c. F. Porsche AG”. So basically, the car was built by students and funded through Porsche’s PR department.

It’d take more of a man than I am to crack into a $400,000 997 Turbo with an angle grinder, but what an incredible project to be involved in.
