The last thing one would expect to find underneath the body of a 2007 Ford Mustang is a Lamborghini Gallardo engine, transmission, and all-wheel-drive system.

Yet what you’re looking at is a fifth-generation Mustang upgraded with the entire running gear from a Lamborghini Gallardo. The one-of-a-kind car was built for the SEMA Show and features a 5.0-liter V10 naturally aspirated engine mated to a six-speed automatic transmission from the Gallardo.

More than $700,000 have been invested in the build which was baptized Tractorri Custom Coupe as a tribute to Lamborghini’s beginnings as a tractor manufacturer. While it may look like a Mustang, the bodywork is completely custom and features Porsche 911 Turbo turn signals, steel fender flares and rocker moldings, as well as Lamborghini Gallardo taillights.

As you can imagine, fitting the V10 in a mid-ship position and connecting it to an E-gear transmission and all-wheel-drive system resulted in significant modifications underneath the bodywork. The car even features a front lift system, also sourced from the Lamborghini Gallardo.

Inside, the Tractorri Custom Coupe features a Gallardo dashboard chopped and modified to fit the Mustang body. The center console and seats come straight from the Lamborghini, along with the HVAC switches, gauges, and controls. The unusual hybrid also features a custom Alcantara headliner, custom door panels, and custom lit sill plates. The Gallardo’s factory keyless entry system has carried over as well.

The car has only covered 2,564 miles (4,126 km) from new and will go to Barrett-Jackson’s Scottsdale auction in January with no reserve.
