Meh, I am so tired of people saying that cars won't be fast or interesting to drive in the future. As long as people want them, someone will figure it out. Tesla and Fisker have already, wait till we figure out fuel cells better or improve the battery tech as well as using composite materials. Heck, the Porsche hybrid RSR beat all the GT cars at the ALMS race at Laguna last weekend while running uncategorized.
Do people honestly believe that Ferrari are going to build Prius type cars in the future? No, they will be exciting and wild, just like a Ferrari today is.
I don't think anyone thinks Ferrari is going to stop making amazing sports cars/super cars, but how many people can afford a Ferrari? Or a Tesla, Fisker or Porsche? More and more mainstream car manufacturers are doing away with their "fun" cars. Honda and Toyota don't make anything to drive around a track anymore, will others follow suit? Sure hope not, but it is definitely a possibility. Toyota has been rumored to be bringing their Subaru collaboration out for some time, but who knows what/when it'll be when it sees the light of day. Honda canned the S2000 (to me an embodiment of a modern sports car, it's fun to drive at 15 mph) and was rumored to be bringing the S3000, but with a lot more weight and more power, effectively killing what the car was. They finally put the NSX out of its misery but scrapped its replacement altogether (not that the NSX was originally an affordable car, or the replacement was going to be anywhere south of $120k), another bummer.
The flipside to all of that is what's happened to engine output in the last ~10 years. Relatively speaking, everything is quick off the line these days, but even with ~280 horsepower you wouldn't want to track a Chrysler Town & Country, but 5 years ago a Crossfire would've been fun to toss around.
