Tuner Tuesday: 2006 Hartge H50

While engine swaps on BMWs seem downright commonplace, there are the normal engine swaps (the well played out S50/52 comes to mind) and then there’s Hartge. The history between the two premier BMW tuning firms in Germany – Alpina and Hartge – is interesting. They’ve vied for the top spot for several decades with slightly different design philosophies. During that time, they’ve also seemingly flip-flopped; originally, Hartge took a more conservative route than Alpina, whose wild turbocharged creations challenged BMW’s own offerings. But after they were granted full manufacturer status in Germany in 1985, Hartge really came into its own and hasn’t looked back since. While like many firms they offer a line of aerodynamic tweats, wheels, exhausts and engine management chips, their party-piece is taking motors from the larger BMWs and popping them into the 3-series models. None of these conversions is more notable than the E90 H50 though. While the E46 H50 took the V8 out of the 5 series, the E90 had a V8 available in the lineup in the M3. Hartge therefore moved up the food chain to the E60 M5’s S85 V10. With a staggering 500 horspower out of the box and even 50 more with Hartge’s tuning, they transformed the rather mundane small executive sedan into a supercar:

Started life as a 2006 US Spec 325i shipped to Germany.

Current Mileage: 32,532

Power: 550 hp @ 7750 rpm

Torque: 391 lb-tq @ 6100 rpm

Weight: 3676 lbs

0-60mph: 4.3 seconds

There is only 1 Hartge H50 in the United States and this is it. Less than 10 exist worldwide.

The H50 conversion package costs roughly $220,000 (new E90 325i included) and takes 7-8 weeks to complete (not including shipping time to Germany).

This car was built to be 100% legal in the United States. The HARTGE H50 Conversion is done at the highest quality of workmanship. All factory features are still functioning. All of the practical functionality of a stock BMW has not been compromised during its conversion. The OBD port and factory check engine lights function like stock.

“A 200-mph BMW 3 Series is one of those deviant cars that we’re just happy to see from time to time. The fact that this one is every bit as easy to live with as the slightly more upmarket M5 makes it the ultimate sleeper.” — Edmunds Inside Line

“Beyond such shenanigans, everyday use is absolutely not out of the question. Just leave DTC on and Power off. The default setting for the seven-speed SMG III (pulled also from the E60) shift rhythm, however, is always at Level Five. For me, this is great since I do that anyway in either the M5 or M6. You can tell Hartge that you don’t want full-time Level Five as the default, sure, but that would, in turn, make you a wuss.” — European Car

“On the plus side, the H50 has the practicality of a 3 Series, including four real seats, highway cruising capability and all the storage any human being could reasonably want from a 200-mph car. Hartge has dressed the interior with a new steering wheel and acres of carbon-fiber, although this is all optional. This 3,680-pound beast is effectively the M5 CSL-Lite that BMW says it simply cannot make.” –Edmunds Inside Line

You may note in the Turner ad that this car was written up by Dan back in 2011. The pictures haven’t changed much and there are some more miles, but even three years on this remains one of the wildest E90 creations out there. It’s also incredibly well executed as you’d expect from a premier tuning firm. One thing that has changed is the price – up $20,000 since 2011. That may seem odd, but it reflects the low mileage, unique package and generally increasing market for BMWs. This is one wild beast, but importantly one with credentials backed up by German’s rigorous standards rather than someone’s garage. As they have since the 1980s, these firms remain on the cutting edge of what’s possible due to their longstanding and close links to the factory, and their creativity and execution push the imaginations of enthusiasts around the world.

    cool idea but unfortunate aesthetic choices

    @Carter – if the work wasn’t performed by Hartge in Germany, is it still a Hartge “backed up by [TUV] standards. . .”? Who did the work, Turner? Or are they just the seller? If they did the work I’d say that’s pretty good street cred still, IMHO.

    I wonder how it is on the street, it seems like it might be a bit much.

    The pictures on the ramp were aggravating, you can’t determine its actual angles & stance. I’m by no means a professional photographer but it’s crazy how many expensive cars we see on here with few high quality pics from all angles in & out. (For $100k I want to see it from underneath too!).

    And the windshield banner is a little too much for my tastes.

    Cool specimen though, and being sold by a well respected shop.

    * my bad, I misunderstood that it was bought then shipped to Hartage in Germany. (Why not just to euro delivery and drive it there yourself?).

    I wonder what happens to your “old” drivetrain, wheels, etc – that’s like $10-20k of takeoff parts.

    PS – I wonder what the import/export paperwork is like to send a car back to Europe temporarily and then sneak back with non-EPA equipment.

    Thorough speculation, but if I had to guess:
    Why not Euro delivery – probably the timetable. From my understanding, you only have a limited time that the car can remain in Europe. Or, it may not have been the original intention of the buyer. I bet this car was at Hartge for many months.
    Why ship over – well, built by Hartge it gets a Hartge Motorsports build plate, but probably not an original VIN (which would appear as European – see next point)
    EPA equipment – do you think they really check? I mean, silver 2006 BMW 325i goes in, silver 2006 BMW 325i goes out. I’d guess the title still states that it’s a 325i. Now, getting it to not flag emissions may be a trick, but I’d guess there’s even a way around that and the S85 was emissions compliant here anyway. Since I think all that Hartge stuff is available here anyway, even the exhaust wouldn’t likely raise any flags, and the wheels and a few shiny badges certainly wouldn’t.

    Just some thoughts

    Carter – I think all of what you’re suggesting makes sense. And ya we’d probably be catching 100% of all illicit drugs that cross the borders before we start catching functional, but mislabeled emissions control equipment. 🙂

    After doing a little more research it looks like Turner is Hartge’s exclusive US distributor, so it makes sense that they would do a sort of show piece even if it was only just driven by Turner for shows and stuff over the years.

    I checked BMW Euro delivery and it looks like it can stay in Europe for up to 90 days (so Turner, don’t complain that you had to ship it both ways on your dime).

    My only other nitpick is the seats/interior trim, you can tell they are non-sport base model…that’s malarkey for this $$.

    We have been taking care of this beast for a few years now. Car is a LOT of fun to drive, definitely a rocketship. The car is immaculate. All work is done by Hartge in Germany. Turner is just the seller here for our client.
    A well put together machine!

    A unique car, but for the same price as a well optioned brand spanking new M5, you’d be hard pressed to select the 2006 grey 3 series 4 door.
