2010 Geiger Cars Shelby GT500 – Click above for high-res image gallery

We don't know why Karl Geiger is fascinated with American performance cars, but we're sure glad he is. The 2010 Shelby GT500 is the latest muscle car to go under the German tuner's knife, and the results are nothing less than impressive. Thanks to a larger Whipple supercharger, larger throttle valves, upgraded fuel injection system and ported cylinder heads, the 5.4-liter V8 produces an incredible 799 horsepower and 697 pound-feet torque. Geiger claims a top speed of 220 miles per hour, but with the Mustang's aerodynamics we would peg that number as more theoretical than anything.

To cope with extra horsepower, Gieger has also fitted the GT500 with a three-disc carbon clutch and reinforced the six-speed transmission. Handling improvements have been made through a "racing chassis" (we're not sure what that means), a panhard rod with polyurethane bushings and adjustable lower control arms. Finally massive 15-inch, six-piston front brakes help haul the Shelby down from inevitable high speed runs. You can see the full press release after the jump, and high-res images courtesy of Gieger can be found in the gallery below.

Alongside the Ford Mustang V6 and its V8 brother Mustang GT there is the crowning glory of the series the wild Mustang Shelby GT500, which is equipped ex factory with 540 PS, an aggressive body and traditional double stripe paintwork. Anyone who remembers the American racing legend Carroll Shelby will be able to instantly imagine how uncompromising and purist the Shelby GT500 factory settings already are. The US car specialist Karl Geiger from Munich has now got its hands on this vehicle and take a look at how the upright Cobra has been transformed into an almost untameable monster!

810 PS, 945 Nm engine torque

As usual the engineers at GeigerCars.de from Munich operated on the open V8 heart of the American muscle car and in the process left no stone unturned. For more pressure they donated a 3.3 litre compressor to the 5.4 litre aluminium engine block which with its 1.6 bar supercharging pressure provides real fire in the forged crank drive. Larger throttle valves, a modified injection system, a 100 millimetre air flow meter and machined cylinder heads also guarantee that the inner organs are fine tuned. Additional coolers for charge air, coolant and engine oil ensure that the eight cylinder can always work at the perfect temperature range despite massively increased power.
Thanks to the massive changes the Geiger Mustang Shelby GT now generates a legendary 810 PS at 6,700 rpm, whereas the maximum engine torque of 945 Nm at approx. 4,300 rpm pulls on the increased differentials. Of course with so much engine torque the transmission also had to be reinforced and in the same step its 5th and 6th gears were shortened. A 3 disc carbon clutch produces smooth power transmission. A special manifold with racing catalytic converters and customised sport exhaust guarantee that exhaust gases are disposed of properly according to type.

High end chassis engineering

So that so much power can also be transformed in acceleration, GeigerCars.de fitted the Shelby with a special racing chassis as well as a Panhard rod made from chrome-moly steel including polyurethane bushes on the ends to balance the axial offset and new reinforced and adjustable trailing arms for improved rear axle directional stability. For the all-important contact to the asphalt surface four classic OZ alloy wheels in 8.5 and 10x20 inch guarantee adequate grip thanks to Michelin high performance tyres in 245/35ZR20 and 285/30ZR20. The upright Cobra is slowed down using 6 piston high performance brakes on the front axle with 380 millimetre large drilled or optionally slotted brake discs.

Perhaps this Mustang Shelby version would also put the fear of God into the US racing legend Carroll Shelby!

      The picture of the engine bay looks stock to me.
        • 4 Years Ago
        Stock brakes as well. It looks like they took the pictures with new wheels and lowered prior to doing the performance mods.

      I have to say that this is like some bizarro first...it's a tuner car version of a tuner car? lol
        • 4 Years Ago
        The GT500 is not a tuner car, it was designed and built in house by Ford. Shelby's name is on the car only because Ford paid him for it.

      I think its great that these German Tuners take interset in American cars. No doubt that this car is a lot of fun. I myself drive a 09 GT and I love the car. I still find it amazing that people will bring up the live axle every time a Mustang is mentioned. Ford has done a lot to make these cars better each year with the live axle. Witness on weekends how well these cars do at the track. But I know that most of the people that do buy these cars dont road race , but they do drag race. Thats where the solid axle works best. Unless Ford comes out with an independent suspension that can take the drag strip abuse, and handle better than the live axle, I see no need to change it. Remember the Corvette uses a leaf spring rear, and it seems to work quite well. So change for the sake of changing is foolish.

      All that and a solid live axle!
        • 4 Years Ago
        Yup and it out handles the Camaro and Challenger with IRS. What is your point?

        Keep in mind I own a 2010 GT500 and driven the other cars so I'm speaking from experience.

        Murray: It ought to, considering Ford spent more than the total money saved by sticking with the live rear axle, in the process of tuning it to not suck so bad.

        Although, in all fairness they wound up with car that out handled its two competitors, while keeping the stronger rear setup.

        Only it doesn't.

        Chevy Camaro:
        Slalom, 6 x 100 ft (mph): 68.6
        Handling rating: Very good

        Mustang GT
        Slalom, 6 x 100 ft (mph): 68.4
        Handling rating: Good

        The only problem with that comparison and your argument is that the Camaro beats it by 0.4 mph using the OLD 315hp GT engine... not the new engine.

        So you are comparing a 426hp Camaro to a 315hp Mustang... and it only beats the silly solid axle Mustang by 0.4 mph
        • 4 Years Ago
        Yep, those are the only other cars on the road. Every other car company is realizing that independent rear suspension is the way to go. However, the myopic view of the Mustang crowd continues to live in the past with the Mustang yestertech rear suspension.

        @Keep in mind I own a 2010 GT500 and driven the other cars so I'm speaking from experience.

        You neither own or drove any of those. If you did, you'd immediately recognize solid axles don't work anywhere except perfectly smooth roads. That's why no one uses them in unibody cars. Except Ford.

      Lose THAT blue, ugh.
      • 4 Years Ago
      Wow, that's the most HP i've heard of coming out of a Mustang. Are they using some kind of variant of the new 5.0 motor, or is that 5.4 the same ol' 3 valver from the last gen?
