BMW 740i With Supercharged E39 M5 V8 Swap Sounds Awesome

This modified BMW 740i Sport is a prime example of tuning done right, as it’s powered by an E39 M5 powertrain… with a twist. Or, more accurately, a supercharger.

BMW may have never offered an M7, but this carcomes real close to what an E38 M7 would -or should- have been.

The perfect proportions of the E38 combined with its under-the-radar styling makes it one of Bavaria’s all-time greats, and this example has received just the right amount of mods to hit home with car enthusiasts.

Finished in its original Alpine White paint job, the car is offered with 53,550 miles at a Bring A Trailer auction. The seller bought it in late 2016 in stock condition and begun its transformation.

A rebuilt 4.9-liter S62 V8 engine, complete with its six-speed manual gearbox, was installed, along with an ESS supercharger, bigger brakes and a limited-slip differential from an E39 M5. Moreover, the suspension was upgraded with Bilstein shocks and struts, H&R springs, a modified rear subframe and axle from a 750i, new sway bars and more.

The interior’s original tan leather upholstery was dyed in caramel by a specialist, while the dashboard now features an integrated iDrive infotainment system that’s reportedly fully functional. The steering wheel and instrument cluster were swapped with items from an E39 M5.

At the moment of writing, the top bid was $40,000, but with four days until the auction comes to an end, we expect the winning bid to be even higher.

      I enjoy the search and build more than anything. Usually get bored after 2 years or so and move to another project. Thank you!!

    • RVAE34

    Its been done like 50 times before.. nothing special.

  • STILL ONE OF THE BEST LOOKING 7 SERIES. THEY SHOULD HAVE LEFT THE INTERIOR ALONE.

    • Ross Fuller

      Interior looks nice, tasteful and purposeful modifications.

      • IF YOU DON’T MIND THE TACKED ON LOOK AND AGGRESSIVELY DYED LEATHER, BY ALL MEANS.

        • MultiKdizzle

          I don’t mind one bit.

  • RVAE34

    Thanks for posting on my car and the kind words! It’s a very special machine and it will be missed. But it’s time to move on to new projects and let someone else enjoy this one.

    • Kagan

      Hey maybe you want to change cars with me, but you have to change the speedometer to km/h?

  • Bash

  • Kimcheebowl

    Gorgeous. Beautiful. Speechless. I don’t care if it’s been done before, timeless mechanicals in a timeless body. Moving on to new projects I assume?

  • Marc Gruben

    Drooled all over my keyboard. Lost all ability to speak. Eyes glazed over. I need this car. I could absolutely die happy. RVAE34, you’ve built a masterpiece. Thank you for sharing it with us.
