Thanks for posting that, Brett. Small detail, FWIW; the article claims that the car does not come with "conveniences" like cruise control, but it's listed among the standard features for US cars on the configurator.

I hear the Cruise control unit adds another 100lbs to the US cars.

The numbers are purely awe inspiring!

"It forsakes fuel-saving measures like engine stop-start"

Good riddance!

" and PDK's coasting feature"

Excellent!

"and conveniences such as cruise control."

Eh? No cruise, Really?

Wow - those interior sound levels seem extreme.

At full throttle, it's as loud as a gas mower, chain saw, or bulldozer! One hour of exposure to that sound pressure level can cause permanent hearing damage! And remember, noise damage is cumulative.

Cruising at 70mph is as loud as a washing machine, hair dryer, or garbage disposal. Sounds fun.

I guess they did away with the creature comforts!

It should be easy to tell who the new owners are. Ask them 'how is your new car?' and they will reply 'WHAT?'.

Let's hope their sound pressure meter is as poorly calibrated as their stopwatches are.

When C&D tested the interior sound level of the 2010 997 GT3 at 70mph it measured at.....77db; exactly the same at the 991 GT3. Must already be a lot of deaf GT3 owners out there.

Say what....?

What comes close in terms of the 70-0 stopping distance? 135 seems like a leap from amazing cars doing the feat in about 145 ft.

Yes as you will see form the table I posted on page 2 the 991 GT3 is pretty much the same noise level as those that have gone before it...

Many cars would turn in amazing numbers with next gen R-comps (I hear MPSC2s are better than Trofeos). Not really an apples to apples comparison to any other car. Not saying that the numbers are not incredible.....but, tires make a massive difference.

To achieve the trap speed of 126 MPH, the engine has to be generating a minimum of 500 HP. Yes, PDK helps, but that trap speed for a "475 HP" car is unreal. The engine is clearly under-rated.

Thats a cop out argument. Thsi is comparative data. We are comparing it to figures for other recent Porsches and GT3 (aslo on R compound).

What about the ambient temperature, weight of driver, age of fuel/octane rating, altitude, condition of tarseal, time of day, humidity???????????????????????????????????????

Yes very had to find apples and apples. Lets not end up in another BS discussion about tyres vs tyres.

Its bloody quick. We know it, its been reported now in three separate independent tests. Discussion closed....

Whats of more interest is the relative power calcs. We knew it was around 490bhp as Andreas told us it was knocking on 500. Wonder how they will position the RS then....

This car was tested in Germany with likely the equivalent of US 95 octane in the tank....This would help to ensure every pony in the trunk was used to maximum effect. I would not be surprised to see Road and Track or Motor Trend post a slower time if they test a car in CA with our junk 91 swill in the tank.
