This is an example that Manhart can tune absolutely anything you give them. They just put another engine on a Z4 just to see “how it turns out”, and it did turn out great with the help of all the mechanics in their team, managing to get a whopping 621 Horsepower on such a tiny car with an unkillable engine.
Ask anyone in the business which BMW engine of the last twenty years deserves the most accolades and therefore the answers will most likely include the S85 mill. That V10 unit was developed back in the BMW Formula one day and it still fascinates enthusiasts of any brand. It had over 500 H.P. and sounded like somebody stepped on Cerberus’ tail. And yet, for some, it still wasn’t enough and tuned versions started shooting up, just like the one stuffed underneath the hood of the BMW Z4 at play here.
Back when the E85 Z4 was still being created, the people from Manhart racing were having tons of fun with the S85 engine. they had so much fun with it that they somehow thought it’d be a decent idea to throw it in the engine bay of a Z4 simply to see how it would turn out. Not solely that but they also modified the V10 to make additional power, as if the 500 it was already making weren’t ok already.
The engine was bored and stroked to 5.8-liters and, thanks to some additional tinkering with the intake, exhaust, camshafts, and different sorcery, they managed to enhance the power output of this enlarged version of the S85 to 621 H.P. Luckily, they additionally modified a handful of other things to make sure nothing blows up once putting this Z4 in motion, just like the gearbox and brakes, as an instance.
This created the MHZ4 600 a record-breaker not in the official sense of the word however more like in an unofficial approach. it’s most likely the most hardcore Z4 ever created and, as you’ll be able to see, it goes extremely quick with a soundtrack worthy of the best F1 tracks in the world. and that manual gearbox is something to die for. Enjoy!
