If you're in the market for a German sports coupe with a naturally aspirated V8, run, don't walk, to your nearest dealer because they are going to be gone very soon. European fuel economy and emissions rules have conspired to force automakers into seeking forced-induction mills. Motor Trend personality Jonny Lieberman is hosting the retirement party in the latest Head 2 Head video, where he takes on the 2014 Audi RS5 and 2014 Mercedes-Benz C63 AMG Edition 507 to decide which is the ultimate Teutonic V8.

To make the decision harder, Lieberman challenges the duo on the first soaking wet roads that Southern California has seen in ages. It forces the coupes to confront some of the actual weather that the rest of the country encounters regularly and serves to even the playing field somewhat between the charismatic rear-drive Mercedes-Benz and the all-wheel drive Audi.

It really is the end of an era for these coupes. The next Audi RS4 is rumored to switch to a twin-turbo V6, and while Mercedes won't officially admit it, the next C-Class AMG will likely switch to a 4.0-liter twin-turbo V8. And we already know the next BMW M3/M4 will rely on a 425-horsepower, 3.0-liter inline-six. Let's enjoy these eight-cylinder German giants while we can, and scroll down to watch the video.

      My two Audi's had lots of problems. My E 320 CDI has been great for 225K miles. I'd take an S 350 BlueTEC, short wheelbase thank you.

      Benz, best built, best ride, best engine. Mercedes get better with age, they don't feel haggard until well over 150,000 miles.

        Really now? I've had the exact opposite experience. Also, MB rates higher than Audi in nearly every single reliability study.

      The RS5, hands down. As if looks alone weren't enough, real world handling and acceleration makes the Merc look overpriced and under engineered. My dealership sells both, so I have no dog in the hunt.

      Fortunately I have friends with both. I've driven both. The RS5 looks better in person. The C Class coupe's front doesn't flow smoothly to the back. The back needs a wider flare. It looks disproportional. Audi on the other hand has the most obnoxious group of drivers I've ever seen, and their commercials are equally annoying. From a driving perspective I'd have to take the C63. There is no replacement for displacement and torque. Driving the RS5 is fun when your in the power band, but that power band is small. The lack of torque is really felt with a heavy driver such as myself (280lbs). You really need launch control to do anything impressive. From a visual perspective the RS5 hands down.

      Don't' even need to watch the video....I'd have an RS5.

      I'm sorry, but cars like this should only be available with a manual by law. If you don't know how to operate a manual tranny, then you should not have an option to get into one of these cars, putting into drive and then simply just step on the gas pedal and go. It invites too many average to below-average people with little to no driving skills, or true interest in driving, to pilot one of these. Yes, in the name of sales, if not for these drivers then companies could not justify this level of car, but then it just becomes something about a pissing match and status than the pure excitement of having all that mechanical goodness at your disposal. The majority of people who buys these will never bring it to a track, never push it beyond 80mph anywhere and would have best been served by a more pedestrian version with no more than 250 hp and been fine.

        I'm sorry, but you're wrong. Two reasons: 1) A dual clutch is faster than you. These are about speed so get over yourself. 2) If you want these cars to exist, there have to be people to buy them. The buyers buy autos. Would rather live in a world where these cars don't exist?

      Having worked for Mercedes, and please forgive me for this MB. I am in love with the Audi. That RS5 is one awesome vehicle. The AWD is just plain crazy cool. So the Audi is my pick.

      Both look like terrific cars, and probably are stupidly fun to drive, so taking a holistic view of things, I would probably opt for the MB based on the one category where it likely is much better than Audi: the after-sales experience. MB is legendary for its customer service, and owning a car like this, I'd expect to be well taken care of after the fact.
