Click above for image gallery of Hartge's V10-powered BMW Z4

Here at Autoblog, we cherish the simple things in life. Like a cold beer on a hot afternoon, spending the holidays with family or stuffing an oversized engine into a little sportscar. It's a time-honored tradition, and this example is no less worthy than any that has come before.

Evidently unsatisfied with the S54B32 inline-six powering the top-of-the-line Z4 M, one European enthusiast dropped in the 5.0-liter V10 from the M5 and M6 into his little Z4. But even the stock 507 horses from the high-revving ten wasn't enough for this Bimmerphile, so he went with Hartge's 550-hp version, complemented by the tuner's own 20-inch rims, but, worryingly, no sign of upgraded brakes to go with the 200+ extra horsepower. The converted roadster cost €170k new, but is now on the market for under €98k (tax in), or about $138,000 in American greenbacks. A hefty sum for sure, but can you really put a price on 0-60 in under 4?

      This BMW definitely lives up to the "Ultimate Driving Machine" moniker. Its a shame that the BMW sportscar is a dying breed.

      BMW SUV'S: X1, X3, X5, X6
      BMW Sports Cars: Z4 *silence*

        So under that logic, the Porsche 911 Turbo and Nissan GT-R aren't sports cars either?
        • 6 Years Ago
        Actually Eddie, you've just mentioned a different breed of sports car, the 2+2.

        http://en.wikipedia.org/wiki/2_plus_2

        On paper 2+2's seat four (obviously), but many 2+2's have rear seats only big enough for young children. Anyhow, yes, the GT-R is a sports car. M3/A5 vehicles are grand tourers:

        What about the M3, M6, 135, 335i coupe? Those are all sports cars.

        Jonathan,

        I am absolutely right there with you. Sports car = two seats, and fairly singular driving focus And there is no dishonor in NOT being called a sports car. It is a matter of classification. There are sport coupes, sport sedans, Grand Touring cars, and muscle cars (sport coupes with big engines, and less emphasis on handling) all can be faster than sports cars, on street or track.

        But a sports car has a singular design purpose, from it's drawing board inception, and the way it is designed, to be rewarding to the driver without excess.

        The M3 is a sport coupe, as is Mustang, Camaro, and many other 2+2 coupes with a sporting intent. A slight practical compromise separate it from a true sports car.

        GT-R is heavy, and big, albeit fast, and is also a sport coupe, as is G37. 370Z is a sports car, shorter, lighter. Unfortunately uglier, although GT-R isn't a looker either.

        The 911 always comes up, as the fence-sitter. Carreras and Turbos tend toward grand touring sport coupes, and GT3 and GT2, in an ironic name twist, are sports cars, with less weight, more focus, and only two seats. 986/987 is a sports car.

        Perhaps he meant roadsters?
        • 6 Years Ago
        Fair point. All of those cars are definitely sporting cars, but I don't consider them sports cars in the traditional sense. To me a sports car seats 2, and they are all about driving. BMW Z4 vs BMW 3, Z4 is more sporting. Audi TT vs A5, TT is more sporting. Thats not to say a 335 can't tear up the track, though.

      The people at Hartage are some kind of crazy!
      • 6 Years Ago
      I was surprised, no... shocked, at how clean the engine installation looks. If you ignore the wheels, this car looks like it just rolled off the factory floor.

      BMW does build too many SUVs.

      "A hefty sum for sure, but can you really put a price on 0-60 in under 4?"

      Caterham Superlight R500 - $61k+ and does 0-60 in 2.88 seconds. Seriously, if you are looking for something that goes 0-60 under 4 seconds, there are better alternatives.

      If i had the money i would definitely jump on it haha. As a Z4M owner i would really like that kinda of power in my roadster and life
      • 6 Years Ago
      Would rather have used the last M5's V8 as the M6 V10 sounded rubbish from inside and V10s I've heard from the outside (Audi S6, Lambo Gallardo) just don't sound special enough; loud, yes, but not gruff like and 8 or sonorous like a 12.

      Whats the German equivalent of rice?

      Those wheels!
      • 6 Years Ago
      The M Roadster's stock brakes are off a previous-generation M3 CSL. Not exactly a setup known for weakness. I be more worried about handling at the limit, as Richard Hammond's test demonstrated. I spun mine twice within the first three months of ownership before I dedicated some quality time on learning what to/not-to do.
      • 6 Years Ago
      That would make a fun sleeper, I would buy it, then have a half rollcage put in the cabin.
      • 6 Years Ago
      Those wheels made me throw up in my mouth a little bit.
        • 6 Years Ago
        I'll hold your hair back if you hold mine. Those wheels are horrible.
      • 6 Years Ago
      I think a 370z with a GT-R engine would be cooler.
        • 6 Years Ago
        That'd be awesome, right up until we see the Z's transmission fall out and tires explode. That'd be YouTube gold material.
