0-60 MPH
968 6-spd Coupe = 6.1 seconds (average from 8x reviews)
Cayman 2.7 5-spd = 5.6 seconds (average from 2x reviews)
60-100 MPH
968 6-spd Coupe = 9.4 seconds (average from 7x reviews)
Cayman 2.7 5-spd = 8.3 seconds (from just 1x review I've seen to date)
1/4-mile trap speed
968 6-spd Coupe = 97-mph (average from 5x reviews)
Cayman 2.7 5-spd = 100-mph (average from 2x reviews)
Avg "G" over 1/4-mile (my favorite as it gives a sense of how hard the car accelerates)
968 6-spd Coupe = 0.24 G (average from 5x reviews)
Cayman 2.7 5-spd = 0.25 G (average from 2x reviews)
Now one area the reviews gave a huge advantage to the Cayman over the 968 was in breaking distances. But don't forget, the 968 tests were conducted on 10-15 year old tire technology.

The oem tires from the 90's will not only hinder decel, but accel as well.
what is the fastest time from the 2 reviews you had for the Cayman? the quickest 968 times i have are from cr & driver. 5.6sec 0-60 & 14.2sec 1/4. Also take into consideration that the 968 tests cars were almost excusively cars not equip with MO30. So the handling & braking distances were not the best they could have been.

Porsche might be playing CAFE (corporate average fuel economy) risk vs. reward games in the US.
Historically they have paid their penalties instead of meeting the mpg rules. They may be sending cars with just enough power to sell; at the same time providing just enough average mpg to offset the CAFE penalties and still make money.
I suspect the tuner markets ability to get big numbers out of modern porsches has changed. In the past porsche brought cars to the US already maxed out. Now they rely on tuners to bring the best out of the cars. They provide the advanced engineering and rely on the aftermarket to bring the big performance.[/quote]
i have to disagree with your last statement. Porsche has not sold a car that was maxed out as far as power goes for a long time. From 930's to 911's to 964's to 928's to 944 Turbo's to 968's....there has always been more power to be had. I cant think of a single car thats maxed out from the factory. People say that about the M3 & S2000 due to their insane hp/liter...but tuners have proved otherwise. Andin the cae of the M3....BMW even brought a more powerfull car to the market with the same 3.2L I-6, only it wasnt sold in the u.s. (M3 CSL with 360HP)
