We can disagree without starting an argument. I only state my opinion based upon limited experience, as I don't trust the opinions of periodicals that sell advertising space to the same companies whose products they are reviewing. I have owned four Porsches, but that doesn't make me an expert by any means.
Back in the mid-eighties, when the exchange rate was favorable, and there was the "one car per person per lifetime" emissions exemption, I made a few trips to Germany to bring some cars over. On one trip, I purchased a 928S, and three Mercedes with 5.0 liter engines. One was a ten year old, another a new limo, and the other a new convertable roadster. The Porsche got spanked by all three.
Porsches in Germany are not as popular as I would have thought. They are a car for a pimp, drug dealer, or man going through a second mid-life crisis. 911s are a lot of fun to drive and tinker with. I think this is because they are a rear engined car, which mechanically is a silly idea, but they have been refined over the years. They get alot of traction, but in bad weather, they go straight no matter what the steering wheel input. The first time I made a lane change on the highway, I almost hit the center divider, the front end is so light at speed.
At very high speeds, they get sloppy. You know how an NSX pushes the front during a high speed turn, imagine having half the grip. How a whale-tail spoiler on the back is supposed to help settle a car with too much weight over the back, I'll never understand.
As far as engines, I think the horizontally opposed design runs out of steam over 100 mph, which justifies Porsches continued use of turbos. The new water cooled engines are much more efficent, and less sensitive to temperature, but still only accelerate half as fast as an NSX over 100 mph.
When driving on the Autobahn, most trips are lengthy, not short bursts of spirited driving. Having a larger engine, that has to work less, means that it has more in reserve than a smaller maxed out engine with twin turbos, intercoolers, and high compression pistons. Also, having the engine over the steering wheels helps settle the car at very high speeds.
If acceleration was all important, we would all be driving Vipers. Too bad the NSX is so under-appreciated here in the states where "Bigger is better". This "Super-Size it!" mentality doesn't improve the breed, only the performance numbers. Heck, American cars became so wimpy, that trucks became the new muscle cars.
Again, these are only my personal opinions, and are subject to my own experiences and prejudices. Your mileage may vary.
