V6 Or V8? Audi’s New RS5 Takes On Mercedes-AMG C63 S

The new Audi RS5 has a lot going for it but does it have what it takes to challenge a hooligan like the Mercedes-AMG C63 S Coupe?

Audi has replaced the naturally aspirated V8 for a smaller, twin-turbo 2.9-liter V6 that pumps out the exact same number of horses (444hp) but offers 125lb-ft more torque for a total of 442lb-ft.

The new German sports coupe sends its power to all four wheels via an eight-speed automatic transmission. Tick the right option and you’ll also get a rear sport differential with real torque vectoring, along with a few more goodies like an RS Sport suspension and a 174mph top speed limiter. 0-62mph comes in 3.9 seconds.

In comparison, the Mercedes-AMG C63 S offers more cylinders, more power and torque and of course rear-wheel drive. It also weighs a bit more which should favour the Audi but AMG has proven that their C-Class is not an easy car to beat.

Motor Trend
pits the two together in their latest Head 2 Head video, which also has Jethro Bovingdon making his first appearance as a host next to Jonny Lieberman.

    V8 hands down, but that is only because its just about time before they stop making and V8’s. or at least sorta affordable V8s.

    The Best or Nothing indeed! Mercedes Benz is killing it this year!!!!

  • Charlie Medina’s Smiling Coach

    Top Gear magazine absolutely crucifies the RS5 in a comparison test on their website. Uploaded today. Merc wins.

  • SteersUright

    Audi wins on looks, interior and that gorgeous paint scheme of black and green. MB wins on monster engine, awesome look in the rear due to very wide rear track and flared fenders, and proper rear drive chassis. Which do I take home? A white C63 coupe. Its got that exotic, untamed factor that makes it thrilling in a way an AMG and RS car should be. The Audi RS is just too tame for an RS car. That should’ve been the regular S or maybe S+ model.

      All agreed man!

    I’m kind of disappointed that Audi didn’t up the HP of the RS5. Should have been at least 500 horses this time. I wonder if Audi being under the VW umbrella had anything to do with this corporate decision. Like the car had to “slot” in between other cars outside of the Audi brand but within the VW brand.

      Because I’m certain they will have an RS5 PLUS in the next few years, so they can milk more money, and bring the spotlight on themselves once again.

    • Belthronding Tinuviel

      Most probably rs5 performance/plus version ll be coming up after some time with more power

      • nastinupe

        Yeah but who makes a next generation car with the same freaking power? Even Porsche adds 15 or 20 HP every iteration.

  • Belthronding Tinuviel

    Audi rs5 should be really good decision but mercedes v8 still keeps me after it
