987 2.7 vs 986 2.5 review

[paintboy]

Experts like Pete Townshend, Tim Curry and Paul Williams all agree that the 2.5 is the engine to own. Many 911's have had their new motors replaced with 2.5s that have upwards of 100k miles on the clock. A spokesman for NASA, B. J. Smegma, stated that if the 2.5 was available in the 1960s, it would have powered the Apollo rockets into space, instead of those silly American made Saturn 5 things. And had 2.5 been available to the German war machine in WWII, who knows how things would have turned out....a Tiger tank doing 0-60 in six seconds would have been unstoppable.....

Thanks Paintboy - you have brought us back to earth! While much less interesting and fun than contemplating the world order if the Germans had the 2.5 in WWII, I just checked the EPA site re: the fuel economy numbers for the 1999 2.5 versus the 2000 2.7:

1999 Boxster 2.5 manual: 17 MPG city, 24 MPG HIghway, 20 MPG combined
2000 Boxster 2.7 manual: 17 MPG city, 25 MPG Highway, 20 MPG combined

Wow, if Porsche changed the gearing on the 2.7 for the purpose of improved fuel economy, they failed dismally! The combined number is identical and the 1 MPG improvement on the highway cycle could probably be explained by anything from varainces in individual cars to the improved fuel injectioin system. Even worse, while trying to improve fuel economy at the expense of performance, they actually by their own admission in the brochures (and as confirmed by contemporary tests) IMPROVED performance. Porsche got it all wrong!

I have not read all the responses in this forum but I understand that the 2.7 Boxster base(2001) does 0-60mph(0-100kph) in 6.5 seconds. So what is reported time for the 2.5 litre engine?

Porsche 0-60 Times & Porsche Quarter Mile Times | Porsche 911 Carrera 0-60, 944 Turbo, GT2, Boxster S, Cayman R, GT3 and Porsche Cayenne 0 to 60 stats!

The above site posts 0-60 and 1/4 mile times for various cars, apparently based upon averages from contemporary magazine tests. They show the following:

1999 Boxster 2.5: 0-60 6.3 seconds, 1/4 mile 14.8 seconds
2000 Boxster 2.7: 0-60 6.0 seconds, 1/4 mile 14.5 seconds

The following is a quote from the above web page in connection with 0-60 times:

"Porsche pegged the 2000 base Boxster at 6.4 seconds in the benchmark 0-60 dash, a modest .3 seconds up on the 2.5 litre original. The real-world time was probably more like 5.9...."

The actual times vary, although it would seem clear that the difference in 0-60 times is at least .3 seconds as between the 2000 2.7 and the 1999 2.5. I don't have my brochures here with me (and I don't have one for a 2001 Base which was a bit heavier than the 2000 due to the lined top and cupholders), but the 6.5 second figure you refer to may reflect 0-100 kph (which is actually a little over 62 MPH), or it may have increased slightly due to the additional weight.
