Say hello to the unofficial BMW Z4 M, as G-Power
likes to call its latest project. The roadster builds on the Z4 M40i spec and
gets an impressive power upgrade that unleashes 500 PS and
700 Nm of torque.
The extra 160 PS and 200 Nm of torque (in the Euro-spec) was made possible thanks to upgrades to the
3.0-liter inline-six engine. As part of the process, the firm installed a
modified turbocharger, a larger intercooler, a new exhaust system and optimized
engine management software.
The 0-100 km/h acceleration time has
dropped by a few tenths of a second compared to the stock model, which needs
4.5 seconds, although G-Power didn’t say by how much. The top speed limiter has
been removed, so the car can now exceed the 300 km/h mark wherever
road conditions allow it. The v-max increase is a € 595 option.
Speaking about the financial bits, G-Power has put a
€ 1,949.99 price tag on the performance software V3, which is the one
responsible for unleashing the full 500 PS. Other mandatory parts are the
turbocharger modification (€ 3,450), downpipe with sport catalyst
(€ 1,950.01) and larger intercooler (€ 1,750). For an extra € 357, they can also measure the engine output on the dyno, so you’ll know
exactly how much power it delivers after the upgrade.
Aside from the boost in power, the tuned Z4 M40i
gets new wheels. The 9×20- and 10×20-inch (front/rear) double, five-spoke
forged rims, called the G-Power Hurricane RR, are wrapped in 245/30 and 275/30
tires, respectively, and are said to be the lightest in their class.
Lesser power upgrades are also available for the
M40i version of the G29 generation, and these will lift the engine output to
380 PS, 410 PS or 450 PS.
The first two kits require an engine software that costs € 1,250 and
€ 1,550, and the latter needs to get the larger
intercooler and downpipe with sport catalyst, too, aside from the engine remap,
for a total of € 5,350, without installation.
