Not many tuners have touched the BMW Z4 let alone turned it into a tuners dream-car until now. Manhart Racing, a German company known for stuffing big V10’s and V12’s in cars that were never originally designed for them, has taken the BMW M5’s V10 and put it in one of their latest creations, a BMW Z4M. Already, the Z4 M is not slouch sharing the S54 engine from the BMW M3 producing about 343hp. Why not slap a supercharger on that inline-6, no no, Manhart had to take it a few notches up… BAAM… A big V10 powers this Z4.
Obviously stuffing the mammoth V10 from the E60 M5 was no easy task but they did that and were able to squeeze another 50hp out of it. They used the same manual 6-speed and rear differential from the donating M5. The clutch was replaced with a Fichtel & Sachs. The V10 is able exhale through an AC Schnitzer stainless steel exhaust system with HJS racing cats.
The Z4 sits on Blistein B16 PSS10 coilovers and .5x19f/235/35ZR19 fronts – 10×19 285/30ZR19 rear black BBS Challenge wheels.
With this complete package you can haul butt from a standstill to 60 miles per hour in 3.9 seconds. That’s fast!
PRESS RELEASE Manhart Racing – BMW Z4 V10
HEART TRANSPLANT – 550 HP in Z4
The M version of the BMW Z4 is famously known by nature for being anything but underpowered, since the chassis of the sports convertible already has a heck of a lot of work with the 343 HP and the forward thrust in the lower gears could last forever.
As is generally known however, the sport oriented motorist can never have enough power at his command. Sufficient cause for Günther Manhart, who by now has over 25 years experience in rebuilding BMW engines – a first for Europe – to transplant a brand new, much stronger heart into the Z4. The transplantation of the ten cylinder engine from the current M5 generation into the narrow engine bay of the roadster was anything but a walk in the park and it earned the Manhart Racing engineers quite a few grey hairs. Nevertheless: everything fitted in the end and now the fire of a 5.0 litre V10 engine with an impressive output of 550 HP blazes above the front axle of the Z4. A catalytic converter, a modified DME electronic control unit and the removal of the factory-set V-Max restriction up to 250 km/h are part of the rebuild. Consistent to the M5 V10 engine Manhart Racing has treated the Z4 to an original M5 E60 6 gear manual transmission which includes a Fichtel & Sachs clutch and a M5 E60 differential. An AC Schnitzer stainless steel exhaust system with four muffler tips which was fitted with HJS racing catalytic converters caters for a perfect V10 sound at the rear.
The Manhart Z4 M V10 goes like hell and thanks to the perfectly tuned Bilstein B16 PSS10 coilovers, the virtually unrestrained power of 550 HP can be brought under control to the tarmac. Black BBS Challenge wheels rotate in the wheel arches of the Manhart Z4 M V10 with 8.5Jx19 ET35 235/35ZR19 front tyres and 10Jx19 ET20 285/30ZR19 back tyres.
Conclusion: 550 HP ten cylinders, an acceleration from 0 to 100 km/h in 3.9 seconds, kerb weight 1450kg, 2.6kg per HP… who could guess that these impressive figures belong to a Z4? Hardly anyone, however Manhart Racing turns dreams into reality and does this with 25 years experience.
