Given that the BMW M5 F10 already has some mileage on it, the expected arrival of the next-generation model in 2018 can’t come soon enough. Sadly, that’s still two years away so for now and the M5 F10 continues to hold the fort for BMW and the M Division. It’s not a bad place to be in considering that the M5 has long been regarded as one of the cornerstones of the M lineup, despite the belief that a lot of its shine has been “stolen” by the M4 and M2. Still, the M5 remains an interesting car, and that holds true for aftermarket companies like CarbonFiber Dynamics, which presented its latest program for the performance sedan, complete with a power upgrade that reaches an eye-popping 818 horsepower.

Yep. That’s 818 horses coming out of the M5’s modified 4.4-liter twin-turbo V-8 engine. It’s a little hard to grasp, but CarbonFiber Dynamics made it work in large part because it was able to focus solely on the mechanicals, while its partner firm, 3D Design, worked on the aesthetics and aerodynamic upgrades on the M5. This program is a two-tuner job, which makes it doubly special in my eyes.

The result definitely speaks for itself, the choice of body color notwithstanding. Everything else though, from the carbon fiber aero parts to the wheels and, of course, the engine upgrade, is top caliber. It’s the kind of program that makes the wait for the next-gen M5 more tenable. Kudos to CarbonFiber Dynamics and 3D Design for cooking it up.

Exterior

The aero upgrades on the BMW M5’s exterior was supplied by 3D Design. The Japanese firm, along with BMW Team Studie, gave the M5 a bespoke “Fire Orange” paint finish to go along with some aerodynamically useful carbon fiber parts like the new front lip on the bumper, new side skirts, a boot lid spoiler at the back, and a diffuser.

In addition to the work of 3D Design, CarbonFiber Dynamics also gave the M5’s exterior a new set of 21-inch graphite grey wheels courtesy of Vossen.

Interior

Note: Interior from standard 2014 BMW M5 shown here.

The release for this program didn't mention any interior upgrades, but to be sure, those who are interested in getting it should contact CarbonFiber Dynamics in the event the tuner can spare a few more of its carbon fiber bits in the cabin of the M5.

Drivetrain

There have been some impressive aftermarket work done on the BMW M5 over the years, but I can't recall one as performance-driven as this one from CarbonFiber Dynamics. Modifications were made to the M5’s twin turbochargers and the downpipes and exhaust system, resulting in an incredible output of 818 horsepower, a massive improvement from the M5’s standard output of 560 horses. No mention was made on torque gains, but rest assured, there are improvements there as well.

With this much increase in output, it’s only natural that the M5’s performance time saw some benefits as well. The tuner didn’t elaborate on a 0-to-60-mph sprint time, but it did say that the tuned version of the M5 can hit 124 mph from a standstill position in approximately 10 seconds. Apparently, it can also get from 62 mph to 124 mph in just 6.6 seconds so if you do the math there, 0-to-60 mph should take just 3.4 seconds, a full second faster than the standard M5.

Curiously, no mention was made on the M5’s new top speed, if it does have one. The standard model is electronically limited to just 155 mph, so if CarbonFiber Dynamics lifted the speed limiter on this one, the tuned version of the M5 could hit more than 200 mph with those 818 horses in full stride.

Chassis and Suspension

No chassis and suspension upgrades are included in this program.

Pricing

Pricing is a mystery, or at least for those who don't bother reaching out to CarbonFiber Dynamics. So if there's any interest, that's the best course to take. Contact the tuner directly to get a proper pricing quote because chances are, it's going to be different depending on where the M5 is located.

Competition

BMW M5 by Speed Buster

Just last month, another tuner took a stab at giving the BMW M5 F10 an engine upgrade. This one comes by way of Speed Buster, which relied on its very own Chiptuning-Box to accomplish the deed. The module is an engine mapping unit that has been at the forefront of every Speed Buster tuning program for more than 20 years and remains at the heart of the tuner’s engine upgrade packages. For the M5, Speed Buster was able to get an extra 71 horses and 103 pound-feet of torque out of the high-performance sedan’s 4.4-liter twin-turbo V-8. The result is a total output of 631 horsepower and 605 pound-feet of torque, enough to give the M5 an increased level of power and performance.

In addition to this M5 program, Speed Buster is also offering a program for the M5 Competition Package that brings power up to 683 horses and 619 pound-feet of torque and another package for the 30th Anniversary M5 that increases the output at 694 ponies and 623 pound-feet of twist.

BMW M5 by Manhart Racing

Truth be told, it’s been relatively quiet in the tuning scene for the BMW M5. But a few years ago, when the M5 F10 was still new in the game, there were a lot of tuners that developed programs for the performance sedan. One of them was Manhart Racing, which gave us this gem back in 2013. This kit was largely made up of an engine upgrade package that included a carbon air intake system and a high-grade steel sports silencer with a pair of 3.54-inch tail pipes that had their own valve control system. The result was an impressive 646 horsepower and 570 pound-feet of torque, enough to increase the M5’s top speed to 196 mph.

Conclusion

There's no mistaking that this is one of the most powerful BMW M5 engine kits we've seen in a while. The 818-horsepower is absurd even for the M5's standards. That alone makes this kit something to consider. Having 3D Design on board also has its benefits as far as the aerodynamic upgrades are concerned. I'm just not sure about that Fire Orange paint wrap. It's too loud for its own good, especially when the car's 4.4-liter twin-turbo V-8 engine already has a nice roar of its own.
