ipse dixit

Interesting observation and numbers from MT tests of the 911/50

Any thoughts on why that would be? Especially given the extras HP in the 911/50 versus the C2S. Is it just the additional weight? The additional drag because of its big butt?

Overall, the folks at MT loved the 911/50.

maybe the presence of the sports chrono in one but not the other? i couldn't think of anything else

The 911-50 is AWD. There is your difference.

No it's not.

The 911 50 is 2 wheel drive so that is not the difference. There must be something else.

Porsche factory claims slightly better 0-60 (3.8) and 1/4 mile (12.1) times and they are usually conservative. My guess is that there are differences in testing circumstances like drivers, temperature and maybe the cars used in the test.
Having said that it was a great endorsement for the car.

Yes & Yes to both. Extra weight & possibly drag are the only logical explanations. The X51 kit does not help much until you get to the top end. In fact if you look at the curves , the regular 3.8 motor pulls somewhat stronger at certain points in the lower end of the curve. Also there is no 4WD despite the wider rear end to provide more traction when starting from stop.

The numbers they quotes seem to be from this story:

The original C2S weighs about 60lb less and came with ceramic brakes (mentioned in the specs table). I image production differences, the slight weight advantage, less unsprung weight, different weather and drivers resulted in the differences.

It's disappointing the 30hp power kit doesn't make a more significant difference other than the price and a nice engine cover. :-(

The 911_50 shown in their test has the yellow calipers - hence Ceramic brakes as well. As @tcbrown states, any number of factors can add up to these minor differences. I can say this much...having spoken to Randy Pobst after this test, he was truly in awe of the car and was totally impressed by the handling - he said it was more dialed than the 918 - FWIW...

Acceleration times can also vary based on the number of miles on the engine. Before placing my order I tested 2 991S vehicles, one with a little over 1000 miles and the other with 11,000 miles. The difference between the two was like night and day. The one with 11,000 miles was very, very quick and very responsive. The other just the opposite. Based on my personal experience the engine really starts to open after 5000 miles. Porsche claims 10,000 miles for the power kit.

Also air temp & altitude make significant differences too, so if the C2S was tested in colder weather it was at an advantage (assuming test was at same track/altitude) and I doubt they would have checked the tyre pressure prior to each test.

Maybe because, in spite of what they say in the article, the car they tested does NOT have the powerkit. Well, the one they photographed for the article, anyway. It clearly does not have the center radiator.

When they botch such obvious stuff it really makes you wonder about the rest.

Money, friendship & favours always test professional integrity to the limit. I certainly see a lot of favouritism in tests & reviews for certain products/companies who incidentally seem to have a stronger PR department!

As an aside the 911/50 no longer shows up on the Canadian web site. I believe they are now all spoken for. Not sure about other countries.

All production was already sold out a couple of weeks ago when I attempted to order one, however I was lead to believe that I managed to get the last unspoken for car in uk yesterday. Would love to know the sales breakdown. I heard from one of the US reps (in rennlist I think) that 599 were sold to US, I'm guessing 1000 for Europe and since UK has a 10% historical share of European market for Porsche - 100 ended up here. Given the popularity of Graphite grey I think 50-60% would have been made in this colour and rest shared between Black & geyser. Would love to know actual numbers or alternative guesstimates.
