The car tuning engineers at Manhart Racing have revealed a powerful version of the BMW Z4 with a 5.0-liter V10 engine producing 550 horsepower. That is more than a 200 hp increase from the factory 343 hp, and allows the car to sprint from 0-100 km/h in only 3.9 seconds. Along with the new 5.0-liter engine swap are new catalytic converters and a customized DME electronic control unit. To accomodate the large V10, the Manhart Racing BMW Z4 received an M5 E60 6 gear manual transmission, M5 E60 differential, and a Fichtel and Sachs clutch. Fitted underneath is an AC Schnitzer stainless steel exhaust system, and the new catalytic converters are from the HJS racing series. Trying to keep the ten cyclinders glued to the pavement are 235/35 ZR19 tires in the front, 285/30 ZR19 tires in the rear, which come mounted on black BBS Challenge wheels.
