Доработки двигателя от немецкого ателье G-Power существенно увеличили отдачу мотора нового поколения баварского спорткара, который после переделки стал еще и сильно динамичнее.

До сих пор последнее поколение BMW Z4 не имеет полноценной M-версии, поэтому образовавшийся пробел заполняют независимые тюнинг-ателье. Одним из последних подобных проектов на базе родстера стал автомобиль от компании G-Power.

BMW Z4 By G-Power

Взяв за основу модификацию M40i с 335-сильным 3-литровым 6-цилиндровым двигателем, путём перепрограммирования блока управления, установки новых турбин и других доработок мастера увеличили отдачу мотора до 494 л.с.

Прирост мощности сказался на динамике. С места до 100 км/ч доработанный BMW Z4 разгоняется за 3,9 секунды против 4,5 секунд у базового варианта. А максимальная скорость тюнинг-кара не ограничена электроникой на 250 км/ч — модель G-Power способен развивать до 300 км/ч.

Все комплектующие можно заказать либо в комплекте, либо порознь. Блок управления двигателем Performance Software V3 оценивается в 1639 евро, новые турбины стоят 2899 евро, модифицированный интеркулер — 1471 евро, а спортивный выхлоп — 1639 евро. Ещё 500 евро придётся отдать за снятие электронного ограничителя скорости.

Единственные визуальные доработки, которые предлагают в немецком тюнинг-ателье, — разноширокие 20-дюймовые колёса за 6681 евро.

The "real" Z4 M by G-POWER: BMW Z4 M40i (G29) with 500 hp

In its meanwhile 3rd edition, the BMW Z4 returns to its roots. Forgotten is the metal roof, from now on, a fabric hood spans over the heads of the passengers, as it suites best for a real roadster. And the visual appearance leaves no doubt that the current Z4 generation is again a true sportscar. As already known from other BMW series, the 40i claims the prestigious addition "M" in the name, thus marking the pole position in terms of performance for the time being, with standard 340 hp (250 kW) and a torque of 500 Nm. Rumors of a "real" Z4 M persist, but have not yet been confirmed. So, BMW enthusiast who just can ́t have enough power have two options now: either prepare for an uncertain waiting time, or head directly to G-POWER now for a performance upgrade.

Key Facts: G-POWER Z4 M40i (G29)

275/30 R20 rear axle / 10,5x20'': from € 6,681.00

(all prices are net)

Because as usual G-POWER - the performance specialist with over 35 years of experience – is one of the first companies to unveil the potential of this racy two-seater. Only a few weeks after its market launch, G-POWER offers already no less than four different performance stages up to 500 hp (368 kW) / 700 Nm.

As usual, G-POWER uses a bespoke software mapping in order to start its performance upgrades. It replaces the standard programming of the engine control unit with the so-called Performance Software V1, a mapping developed by G-POWER for the new Z4, which produces an extra 40 hp and 30 Nm. A somewhat "more aggressive" tuned V1 S version of the Performance Software boosts the maximum power output to an awesome 410 hp (301 kW) / 580 Nm. A plus of 70 hp and 80 Nm. Everything purely electronic and without changes to the hardware periphery of the inline-six-cylinder engine. 

Modifications of the periphery are only needed from the next performance stage on. Here, G-POWER combines flow-optimized downpipes incl. sports catalytic converters with the matching tuned Performance Software V2 and the in-house high-tech all-wheel-dynamometer already measures 450 hp (331 kW) / 640 Nm. The G-POWER range for the BMW Z4 M40i G29 is completed by the aforementioned stage with 500 hp (368 kW) / 700 Nm, with which G-POWER not only anticipates the Z4 M, but in all likelihood even beats it. It goes without saying, that for a performance level like this, extensive modifications to the exhaust system and the standard supercharging system are mandatory. So, in addition to the downpipes from stage 2, a modified turbocharger is part of the package, as well. It is supported by a G-POWER intercooler with enlarged cooling capacity. Can be combined with all power levels and is absolutely recommended: the G-POWER Vmax increase. With this option, the upgraded BMW Z4 M40i can transfer its gained power in unrestrained speed, so that the speedometer needle can move - depending on the power level – up to the 300 km/h mark and beyond.

After all, safety is a top priority at G-POWER. It goes without saying that all standard diagnostic and motor protection functions remain untouched. To verify this, the G-POWER engineers rely on the features of the G- POWER high-tech dynamometer. Equipped with an eddy current brake, individual load points can be selectively controlled and held. Thus, the reality on the road is simulated perfectly and under controllable conditions. So, G-POWER can test its performance increase during all relevant operating and load condition of the engine during a vehicle life. This allows G-POWER to get the most out of the engines without overstraining them. Everyday usability and reliability are just as much a matter of course at G-POWER as gaining the best possible power output.

The distinguished appearance of the G-POWER Z4 M40i is further enhanced by the 9Jx20 and 10Jx20 double five-spoke G-POWER HURRICANE RR forged alloy wheels shod with 245/30 R20 and 275/30 R20 tyres. Forged from aircraft-grade aluminium, these ultra-light and very strong wheels, designed by CAD and optimised by FEA, are the lightest in their class, and lower the unsprung weight, for improved acceleration, handling and braking.
