When you have a Lamborghini, but Mustang is life. We still... can't get our heads around this one. Okay, so this is pretty much old news, but it popped up again when it came across our office desk last week.One crazy guy took modifying his car to a whole new level when he seemingly woke up one morning and wanted to turn his perfectly good Lamborghini Gallardo into... a Ford Mustang. Now we have to admit, the level of workmanship that went into this build is impressive, but it still begs the question: why?! Above: Blueprints, you know, in case you want to follow in this man's footsteps. Above: Impressive engineering work. Codenamed "The Tractorri", a Lamborghini Gallardo's engine, drivetrain, and interior was transplanted to a 2007 Mustang body. Above: Interior is retained from the lambo. The build also involved using two Mustangs for parts and thousands of hours of labor fabricating custom one-off parts. Above: Body panels from the mustang are grafted onto a modified mustang chassis. The Tractorri Gallardo Mustang uses the mid-engined all-wheel-drive powertrain, a 520 horsepower V-10 monster. Above: The car is powered by the 520hp V10. The rear of the car was reworked with custom fabricated parts to imitate the Gallardo's rear-end, to further add to the one-off design of the car. The Tractorri Gallardo was on display at the 2007 SEMA show for all to see. The finished result is certainly impressive, and no doubt handles and performs far better than the Mustang part of its donor, considering it retains all the same suspension, driveline and brakes. The exterior is finished in a custom metallic candy apple red. The main give away for a casual observer would be the lambo wheels and huge brakes... oh and the rear engine. Above: Looks like a 'stang from this angle. Above: The rear looks somewhat awkward, where it retains the Lamborghini's tail lights, and rear cooling vents. Above: I can see what they were trying to do, but it still doesn't look quite "right"... Above: Functional intake vents. In case you thought this was just a static display done simply for 'wow' value... Think again... Catch the video at the top of this article to see it running. The car apparently went up for sale a few years back. We're unsure what came of it, or who bought it, but we hope they manage to keep the "crowd control" gene out of the hybrid build... (yes yes, you were thinking it, someone had to say it!)According to the seller's agent who posted the vehicle for sale:"The crown jewel of our private collection: The Tractorri. The short version? This is a body-in-white '07 Mustang shell with the mechanicals from a Lamborghini Gallardo underneath. From the ABS to the AWD to the E-gear transmission everything works. The long version adds two more Mustangs for parts, thousands of hours of labor and enough one-off parts to make most show cars blush. "Oh, and our president drives it around—he put over 1500 miles on it this summer alone! Built and maintained by our own Rick Roush this is a werewolf in wolf's clothing! Check out the pictures for now and we'll have a full description of the build and show history up shortly!"Now that you are completely confused, we will leave you with some close-up shots showing the level of detail and engineering that went into this build.. Even so, the age old adage comes to mind.. Just because you can doesn't mean you should.
