Manhart Racing – BMW Z4 V10

Fans of the BMW Z4 would surely have been disappointed to learn that Munich is not planning to introduce an M version of the new two-seat hardtop. The highest that the Z4 goes as far as power is concerned is 225kW (306hp) which might increase to 245kW (333hp) if the BMW Motorsport kit is introduced for the model. Other than that no manic coupe/ roadster is in sight.

Panic not Z4 M fans because Manhart Racing has a solution. The tuner, whose founder Günther Manhart has 25 years of reworking BMW engines under his belt, has shoehorned the V10 naturally aspirated engine from the M5 and M6 into the small and narrow body of the Z4. Fitting such a monster powerplant proved a harrowing challenge but one that was eventually overcome. Now it sits just above the car's front axle. The total kerb weight is 1,450kg.

Factory power is a good 373kW (507hp). Manhart has increased this to 405kW (550hp) by, among other things reworking the ECU. Performance looks to be quite strong with the 0 - 100km/h dash said to be attainable in 3.9 seconds. They have also removed the 250km/h speed limit.

Other modifications include an AC Schnitzer stainless steel exhaust system with four muffler tips, an original M5 E60 6-speed manual transmission which includes a Fichtel & Sachs clutch and a M5 E60 differential. All the equipment is kept on tar by 8.5Jx19 ET35 235/35ZR19 front tyres and 10Jx19 ET20 285/30ZR19 rear tyres.

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.

But that doesn't help owners or those who aspire to own the overall significantly better current Z4, because this conversion is based on the old Z4 which had an M version anyway...

The Engine is pretty cool, and I love those BBS wheels. The Z4 is just meh though.

In europe the M5 has and 7 speed smg gearbox, but why have americans the option to choose for a 6 speed manual?

the 6 speed manual M5 that the Americans got has a non switch-off able traction control

This is insane. I prefer the looks of the older Z4 much more than the new one. And with that V10 this a masterpiece.

the old one is the better choice , it's lighter. i wonder what the weight distribution is in this thing.

because most people around the world do not mind to have their bread buttered on one side. americans want their bread buttered on both sides. they nagged for the 6 speed and it turned out that the engine was tuned and built from the early stages to work with the SMG transmission. end result: a worse performing car due to a unfit transmission. if they stuck the smg in this z4 i think after it hitting about 300kmh it might start to fly :-). this is no doubt one of the best z4 project ive ever seen. if they could only sqeeze a bit more space for a twin turbo set up i would sell a kidney or some other body part worth money to buy 1 :-)

Absolutely fully sick...Manhart sure are making heads turn and hearts beating V10 times faster than normal...still a personal favorite is the M3 E91 5.0 V10 SMG Touring...i'll take that any day :)

they should have coupled the smg gearbox on to this rather then the 6 speed

Interesting, they've used the Z4 M body kit rather than a tasteless design.
