The great thing about unheralded aftermarket companies like Noelle Motors is that it doesn’t have to live up to the pressure of having a well-recognized name. But, even with the bar not being set as high as most of its established brethren, Noelle Motors’ new program for the BMW M6 Convertible may be just as good - if not better - than what we’ve become accustomed to in the industry. Then again, it’s not like Noelle Motors has no experience whatsoever. A quick look at its website shows a series of impressive programs for the entire BMW model lineup. That’s a pretty good indication that the company, under the leadership of Karl-Otto Noelle (the former head of engine development at Alpina) knows what it’s doing.

So, is there anything worth raving about with this program for the M6 Convertible? As I said, this kit is certified aces. It doesn’t have any of the cosmetic upgrades that some tuners have, nor does it have anything that resembles “improvements” in the cabin of the M6 Convertible. But, what it does have is an engine program that takes the car’s 4.4-liter, bi-turbo V-8 engine and bumps up a power improvement that will make the G-Powers and Alpinas of the world applaud.

A lot of people might not know about Noelle Motors today, but if it can build off of the momentum of this tuning kit, it’ll only be a matter of time before the tuner gets the recognition it deserves.

The BMW M6 Convertible doesn’t come with any noticeable exterior upgrades other than the new set of alloy wheels dressed up in a matte black finish. Other than these wheels and the BMW Individual Frozen Brilliant White paint finish, this M6 Convertible is about as stock as they come.


Much like the exterior, the interior of the M6 Convertible will still have its standard configuration. Noelle Motors barely even touched it, so if you’re also expecting to see those throw-away floor mats, you’re going to be very disappointed. On the bright side, the M6 Convertible has one of the most well-dressed cabins in its segment so it’s actually better served without any upgrades on the cabin.

The absence of any notable exterior and interior upgrade isn’t so much of a problem for this program, especially when you consider the impressive nature of its performance improvement. Consider this for a second. The BMW M6 Convertible is powered by a 4.4-liter, twin-turbo V-8 engine that pumps out 575 horsepower and 501 pound-feet of torque. Those numbers are already good enough to propel the luxury droptop from 0 to 62 mph in just 4.3 seconds to go with an electronically limited top speed of 155 mph. Those are great numbers for a stock model, but not good enough for a tuner with a pedigree in aftermarket programs for BMWs.

So, Noelle Motors installed a software optimization unit and exhaust downpipes with free-flow sport metal catalytic converters. The result is an incredible output of 766 horsepower and 650 pound-feet of torque. More importantly, Noelle Motors removed the M6 Convertible’s electronically regulated speed limiter, pushing the M6 Convertible’s top speed to a stomach-churning 215 mph. Those are some serious fireworks right there.

Sadly, there is a downside to the tuner’s Stage 3 kit, especially for those living in Germany. The upgrade itself is considered illegal in that country so anybody looking to avail of it can’t drive on German roads. The kit is available for export, so that’s the good thing. In any case, Noelle Motors is also offering Stage 1 and Stage 2 kits that can push the M6 Convertible’s output to as much as 740 ponies.


No pricing details have emerged for this program. Noelle Motors’ website also doesn’t have any pricing information so if you’re interested in knowing more about this tuning kit, contacting Noelle Motors directly is your best shot at finding out what you need to know about this program.

Noelle Motors isn’t as big a tuning company as some of the more recognized tuners are. It certainly isn’t as big as G-Power, considered by most as one of the biggest and most recognizable tuning firms in the business. I bring this up because back in October 2015, G-Power actually released its own kit for the M6 Convertible.

In typical G-Power fashion, its tuning program mostly focused on engine modifications. At the heart of these modifications is G-Power’s Bi-Tronik 2 program, which is largely responsible for the bespoke remapping of the M6’s standard ECU unit. This program gives the M6 Convertible an output of 740 horsepower and 720 pound-feet of torque, right square in the neighborhood of Noelle Motors’ own program.

In addition to the engine upgrade, G-Power also installed flow optimized downpipes on the exhaust system that can be installed without catalytic converters or 200-cell racing-catalysts. This configuration helps reduce back pressure on the exhaust, paving the way for the engine to see its performance output to clear 700 ponies. The German tuner also offered 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.

For an aftermarket firm that isn’t as recognizable as the G-Powers, AC Schnitzers, and Alpinas of the tuning world, Noelle Motors sure knows how to make a splash. I don’t mind the fact that this kit doesn’t have any cosmetic upgrades since a lot of tuners don’t do it themselves. What I’m impressed by is the level of power it can generate out of the M6 Convertible from its performance modification. Last I checked, 760 horsepower coming out of a 4.4-liter V-8 is staggering in it of itself. Noelle Motors did just that, proving that just because it doesn’t have the name (yet), that doesn’t mean it can’t provide results as impressive as this one.
