All German Kansas City Car Show



The interior on this one has the Designo option, which usually runs around an extra ten grand.  The leather is to die for and the styling, well, see for yourself.  Check out the all-electronic dash.  It even comes with different types of interior scent choices (yes, scent!) as well as LED colors for the lighting.

I just couldn’t get enough of these seats.  Imagine this kind of styling and comfort, and yet this non-AMG car, thanks to its 4.7-liter V8 twin turbo rated at 450bhp and 516 lb-ft of torque, is propelled to 60mph from a standstill in just 4.5 seconds.  Beyond the S550 there’s an AMG (S63) version with a 5.5-liter V8 twin turbo that will do it in 3.9-seconds in stock form.  Very nice.

Speaking of big AMG cars, I’ve already seen 580 wheel-hp, pump-fuel dyno figures with over 600 lb-ft of torque on otherwise stock 5.5-liter AMG turbo Mercs, upgraded with just Renntech software.  Yes, just software!  Even the older 5.5-liter V12 turbos on the S600s couldn’t surpass 525whp with software alone—their turbos were maxed out.  And the 6.0-liter V12 turbocharged AMG S65’s maxed out around 560-570whp with software alone.  The Mercedes cars of today really mean business (done quickly)!


While Audi didn’t have much representation that day, a few guys showed up in lightly modded RS4s and  RS5s.  I caught this RS5 as it shot out of the parking lot, but with not enough time for me to make the proper camera adjustments.  Still, with its big brakes and bronze-colored HRE monoblock wheels, I figured it was still worth showing.  With a stock 450 bhp from its naturally-aspirated 4.2-liter V8, this tank will do 0-60mph in 4.4-seconds and a 12.8-second quarter-mile in stock trim.  That’s an impressive specific output for an engine of this size.
  It’s not often you see a B7 Audi RS4, let alone a yellow one.  With the same engine displacement as the RS5 above, the RS4 accelerates with about the same quickness as the RS5 while making due with 30 hp less.  We don’t know what other upgrades were on this car, except for a clearly visible AWE Tuning cat-back exhaust system.  The car sounded mean when it drove in. 

I spent some time modifying a local friend’s Audi RS4 before and, contrary to popular belief, these cars can respond well to basic mods.  Starting out at 320 all-wheel hp on Modified by KC’s dyno, we finally ended up with 361 awhp with the addition of Stratomosphere/Milltek down-pipes with high-flow cats, a Magnaflow exhaust, GruppeM carbon fiber intake and Revo Technik stage 2 software.


Ahh..the Porsches.  I’ve always said there’s nothing more intoxicating to drive than a modified 911 Turbo.  Did you know that stock 997 turbo wheels are extrememly light.  I remember fitting one for a magazine article with stock-sized Dymag Carbon fiber wheels with Magnesium centers and titanium lugs (the lugs were a $1200 option on these $10k wheels).  And we lost 1-lb per corner.
