Reading about these vehicles convinces me that even if I wanted to, or could afford to, replace my 2002 M3 convertible, I certainly wouldn't replace it with one of these. Mine has a proper manual transmission and none of the gimicky electronic stuff that seems to float everybody's boat these days. It's an absolute HOOT to drive--and isn't that why you should buy a car like that in the first place?

A mid-engine sportscar weighing less than 3200 lbs. against three sedans with two doors removed. That's an honest comparison? Where is the CTS-V? Why this Audi? Comparing different cars with different purposes is either stupid or dishonest.If the goal is to provide readers with a comparison of viable options, it seems to me that those options ought to be aimed at the same compromises and uses. This is just silly.And you didn't even stick to your price criterion. The Boxster tested is almost 50% over the line.

What baffles me is why none of these were tested with a real transmission, instead of slushboxes. If no manual is offered than strike one right there! For $64K I want a car to be engaging, and that means letting me do the shifting!!

Great car!

Why the constant emphasis in track specs ? 98.5% of the readers will never take their street cars to a racing environment, or really give a damn about lateral g's. What I want to know is how these or any other cars you report on will treat my lower back after a three-day road trip. Human issues, please.

Great video! The Traverse City area is one of favorite driving destinations----"Up North" from my Ann Arbor home town. I wrote a letter to Automobile telling them that they just "don't understand" all wheel drive. Watch the Stig vs Jeremy Clarkson on Top Gear. The Stig gets around the track WAY faster because he doesn't make useless blue smoke from the rear tires. Audi got around the track 1.5 seconds (a lifetime in a race!) faster than the bogy target M3 by not spinning its tires. And it came in third place! Methinks these car testers are aping that heavy handed ape Jeremy! Blue smoke wins again. Not!!!Meanwhile, I'll smile every mile in my own Audi 4.2 V8---in a 2004 allroad. An amazing vehicle---in any weather and on any sort of road---even playing with the Jeeps in the rough stuff.

With peak acceleration of 0.85g's the Audi trumps the other three cars by quote a margin. IMHO this throw you back in the seat acceleration should add to the dynamic edge the report says is missing in the RS5. The Boxster (one of my all-time favorite cars) clearly does not belong in this group. The BMW may well be the "as tested bargain of the remaining three, but for non-track, Northeast winter driving, I would go with the Audi and might. I have an A6 now and need something more exciting.

Now that you have included the 2013 Porche Boxster, a two seat sports car along with the two seat (minimal back seat)coupes, why not include the Audi TT RS?It may not be the track car the Boxster is, and few cars are, but I would take the TT RS (4.1 secs. to 60) and fabulous Quattro drive system for the open road any day.

WOW it's funny how automobile mag did'nt include the cts-v its a better car than all the above cars, it seems like they did'nt want the caddy to show them up i understand

So the heavy, isolated RS5 shows its taillights to the Boxster S on the track? Matches my on track experiences exactly (srsly).
