BMW Z4 By G-Power

German tuner offers extra power and suspension mods

---

 G-Power has released performance upgrades for the latest BMW Z4 including a chip that’s said to shave half a second off the twin-turbo 3.0 litre six’s 0-62mph time.

The so-called Bi-Tronik performance module bumps power on the sDrive 35i to 345hp from the standard car’s 306hp. Torque is up too from 295lbs ft to 354lbs ft, with the result being a reduced 0-62mph sprint time of 4.7secs.

G-Power is also offering a stiffer and lower coil-over conversion kit that uses adjustable shock absorbers with nine selectable settings, and a quad-tailpipe exhaust system with a noisier rear expansion box.

The whole package rides on a set of 20ins G-Power Silverstone alloy wheels that are lighter than the standard wheels thus reducing unsprung weight, and wrapped in 255/30 ZR 20 front and 295/25 ZR 20 rear Michelins.

The cost for all this extra goodness is measured in Euros: The wheels and tyres come in at €4,474, the suspension kit is €1,256 and the engine upgrade is €1,978.

4.7 secs - not bad.

[Rex Ironstone]

waahey there it is. Not much of a looker. although I actually like it slightly more than the last one.

[AlmeraGTi]

Lol all that time i ws trying to make a comment about thiss car. Its Ugly. The old 1 looked alot nicer.

[Crusoe]

wonder what the limits are on that dsg gearbox, would imagine that goes over the manufacturers specification torque wise?

[BoRED S2upid]

Quite a reasonable upgrade package considering what some tuners charge nowadays.

[Mr Whippy]

Yeah, pretty cheap.

Not sure it doesn't look too high now, ground clearance looks quite large for this kind of car (might be the angle!?)
And you can't really lower it as the wheels are already up in the arch nicely.

Hmmmm, room for improvement in the appearance I rekon. 20" wheels is just mad

[vz-r_dave]

mate of mine hired one out for a weekend here in germany and he says its rubbish. No power or feel what so ever, that was a 2.4 model though.

Doesnt look that bad imo

£7000 for some st wheels and half a second off the 0-60!

I'd rather have a standard car, this:

& £500 for a dirty weekend thanks!

[SpunkyM]

Agreed, two grand for a chip is an enormous amount of money. But then I guess they are not betting on selling very many so they are trying to scrape their development costs back.

[derestrictor]

I like 'em. That will fly.

[Jackal2k9]

stick on 15's n it'll fly never been a great fan of big massive wheels lose to much speed

Look up G-powers past offerings for the mk1 Z4, and it is cheap!

im sorry but you cant compare the two cars 1 is a pure monster and the other is a hairdressers car dressed up 2b a pretend sports car

[Trixman]

€2k for a 'chip' is just ridiculous. You can get an ECU tune for this engine from any of the main suppliers for around 5-600 pounds. Sticking a brand name to it doesn't justify that kind of price hike.

[AstonV12]

I like it alot... but I cannot help thinking that the installation of a fixed roof and the 4.0 //M V8 would transform this car in what we want

[btdk5]

Ooo that does not look good in white!

Anyway....would this not wreck your warrenty?

[Shabs]

They do look good, saw one in the metal on the weekend, very nice, awesome in fact

[tomvcarter]

Are G-Power a respected company???
I see they now have a supercharger for the e92 M3, enabling 600bhp!!!
But from the clips i have seen it can t keep the power down, anyone know anything about it?

[Warick Hunt]

They have tried to improve the awful styling from the original but it hasnt really worked its still a bangled mess. 2K for a £5 chip with copied software is bare faced robbery, more fool anyone who thinks about paying that. Although the typical hairdresser owner probably wouldnt have a clue anyway.

[RacingPete]

Looks lovely
