Known for its propensity to cook up some of the most astounding performance programs in the business, G Power is back at it again with a kit that can help the M6 Convertible become one of the fastest and most powerful drop-tops in the world.

The tuning firm’s Bi-Tronik 2 kit comes with enough engine modifications to add over 200 horsepower on tap of the high-powered convertible’s existing 516-horsepower output. Power has always been G Power’s MO in the industry so this kind of kit is to be expected, especially when the car in question is the M6 Convertible.

On its own, the M6 Convertible already has enough horses under its hood to take down the competition. But for some people, in this case, G Power, “enough” isn’t really “enough” if there’s still room for improvement. That’s the kind of mantra that G Power lives by and it’s showing yet again just how good it is at turning BMWs into certified rockets on wheels. All told, the company’s Bi-Tronik 2 kit is a real game changer in the aftermarket scene.

Sure, there are no hints on how much the program is going to cost, but expect it to be a little higher than the amount you’ll need to pay for a standard BMW M6. That comes with the territory of having a G Power tuning kit that helps enhance the M6 Convertible’s performance capabilities.

Don’t bother looking for any exterior modifications on the BMW M6 Convertible. Other than the set of new, 21-inch, ultra-light, aircraft-grade aluminum wheels from Hurricane RR. The M6 will remain as it is. Speaking of those wheels, G Power is offering three different shades, including Jet Black, Gun Metal Grey, and Stardust Silver. Owners can also opt to have their wheels painted in a special color, although that’s going to come with an extra cost.

Just like the exterior of the car, G-Power left the M6’s interior alone. There are no upgrades made to the cabin, although if you’ve ever been inside the M6 Convertible, you’d wouldn’t have any problems keeping its setup as it is. The interior is one of the understated highlights of the drop-top 6er so it’s perfectly fine in its standard configuration.

The vast majority of changes to the M6 are impressive modifications given to the 4.4-liter, twin-turbo V-8 engine.

At the heart of these modifications is the Bi-Tronik 2 program, which is largely responsible for the bespoke remapping of the M6’s standard ECU unit, allowing the engine to produce as much as 740 horsepower and 720 pound-feet of torque. That’s pretty much the gist of it, but the process behind isn’t that simple.

In order to accommodate the massive increase in output from the M6 Convertible’s engine, G-Power aided it by installing different performance modifications in various parts of the car. The exhaust system, in particular, was given flow optimized downpipes that can be installed completely without catalytic converts or 200-cell racing-catalysts. This development reduces the back pressure of the standard exhaust system, essentially clearing the way for the engine to increase its output to 700 horsepower. G-Power is also offering a complete titanium exhaust system comprised of a titanium four-tip sport silencer and link pipes with resonators as part of the stage V3 program for the M6.

A few tweaks on the car’s software puts the M6’s total output at the 740 horsepower level with 720 pound-feet of torque. These new numbers allow the M6 Convertible to sprint from 0-to-124 mph in just 10.7 seconds to go with a top speed of 186 mph.

G-Power specializes on building some of the most impressive engine programs for BMW vehicles so I’m not the least bit surprised that it’s taking a stab at the M6 Convertible. This actually isn’t the first time that the German tuner has worked on the M6, although those past versions were for the M6 Coupe and M6 Gran Coupe.

By itself, the standard M6 Convertible already packs a wallop as it can bust loose to the tune of 560 horsepower and 500 pound-feet of torque. That’s enough to propel the car from 0-to-60 mph in just 4.3 seconds. Sure, its top speed is electronically limited to just 155 mph, but that shouldn’t take away from the car’s overall capabilities.

But G-Power isn’t interested in those numbers because it believes that the M6 Convertible still has a lot of untapped potential that’s just waiting to be unleashed.

The basis for the electronic output increase from G-POWER for the BMW M6 convertible is the fact that G-POWER, in contrast to the manufacturer, does not use standard software full of compromises for the engine but an individual solution. G-POWER calls this bespoke remapping of the factory ECU: Bi-Tronik 2. Among others, the parameters for the amount of fuel and the ignition timing are modified depending on the increased boost level. At the same time the Bi-Tronik 2 allows the individual wishes of the customer vis-à-vis throttle response and power delivery characteristics to be written into the software.

Of course all standard protection and diagnostic functions of the original BMW ECU stay untouched. During the engineering process of the latest generation of the successful Bi-Tronik the G-POWER R&D department has transferred its experience from the area of supercharging to the turbocharged BMW engines. After all, the ASA supercharger used for the G-POWER supercharger systems is closely related to the turbochargers featured by BMW, since both units us a centrifugal compressor to build up boost.

In order to achieve a power output upgrade to 740 hp (544 kW) 975 Nm, the modification of the ECU’s software is not enough and additional modifications to the M6’s hardware are required. Primarily it is necessary to reduce the performance debilitating backpressure of the standard exhaust system. Therefore G-POWER installs in a first step flow optimized Downpipes that are offered either completely without catalytic converts or 200-cell racing-catalysts. With this modification done the power output increases to 700 hp (514 kW)/ 905 Nm and is standing as stage V2 of the Bi-Tronik in the G-POWER price lists. With stage V3 a complete Titanium exhaust system - incl. Titanium 4-tip sport silencer and Titanium link pipes with resonators starting from the Downpipe - is added on top.

In addition to the power output increase the G-POWER Titanium exhaust system gives the BMW M6 convertible a deep, throaty sound that turns heads but is at now time annoying and at the same time saves approx. 12 kg compared to the factory exhaust system. The G-POWER exhaust system is available with four Titanium or Carbon Tailpipes with a diameter of 100 mm each.

Naturally the extensive modifications that G-POWER has done to the soft- and hardware of the M6 have a substantial effect to the performance figures, as well. The figure from stand still to 200 km/h is now just 10,7 seconds and the top speed is more than 300 km/h, thanks to the G-POWER V-MAX increase.

Reduced unsprung mass equates to improved handling, both of which G-POWER achieves with its 21-inch HURRICANE RR forged alloy wheels shod with 255/30ZR21 and 295/25ZR21 Michelin tyres.

Made from ultra-light aircraft-grade aluminium these wheels are normally available in Jet Black, Gun Metal Grey and Stardust Silver, but can also be painted in a special colour at extra cost upon customer request.
