German tuner presents three-stage engine kit for BMW’s flagship model

As one of the true stalwarts of BMW’s entire lineup, the 7 Series has represented the pinnacle of German luxury for almost 40 years. And as customers continue to flock towards the 7 Series, don’t expect it to just fade off into the sunset anytime soon. Even aftermarket tuners have shown some love and affection towards the big 7. The latest to do so is Noelle Motors, and it’s promising a three-stage engine upgrade package that gives the 750i variant as much as 629 horsepower and 605 pound-feet of torque.

Those who aren’t familiar with Noelle Motors should know that the man behind the company is Karl-Otto Noelle, once the head of engine development for Alpina back in the 1980s. Noelle gained acclaim in his time with Alpina with his ability to extract added power from the engines using methods pertaining to turbocharging. Noelle’s wealth of knowledge in engine modifications has translated in modern times as his own tuning company has earned its own reputation as one of the best BMW tuners in the business.

Even though it lacks any exterior and interior upgrades, this program for the 750i achieves its intended goal because it focused on the thing it does best: engine upgrades.

And for those who are wondering if the power improvements are enough to justify purchasing any of the three-stage kits, don’t stop here. Keep reading and find out for yourselves.

Since there are no exterior or interior upgrades included in this program, Noelle Motors’ kit for the BMW 750i revolves around the sedan’s 4.4-liter twin-turbo V-8 engine. The whole program involves a three-stage upgrade that begins with the simple S1 upgrade.

The result is an output of 629 horsepower and 605 pound-feet of torque and a sprint time to 62 mph in just 3.6 seconds

It’s a simple upgrade because the only modification Noelle put into the V-8 is optimizing the engine’s software unit. But even with just the tinkered software, Noelle was still able to add power to the tune of 590 horses and 560 pound-feet of torque, an improvement of 145 horsepower and 80 pound-feet of torque and a dramatic drop in the car’s sprint time to 62 mph to 4.0 seconds compared to 4.7 seconds on the standard unit.

Then there’s the S2 upgrade, which adds a free-flow exhaust downpipe to the remapping of the engine’s control unit. This upgrade puts the 750i’s output to an impressive 609 horsepower and 583 pound-feet of torque, netting a sprint to 62 mph time of 3.8 seconds.

Finally, there’s the S3 upgrade. This one adds modifications to the turbochargers as well as the installation of larger downpipes and the remapping of the engine’s control unit. The result is an output of 629 horsepower and 605 pound-feet of torque and a sprint time to 62 mph in just 3.6 seconds, a number that essentially makes the 750i’s acceleration capabilities to be worthy of a supercar.


Joelle Motors didn’t reveal the pricing details of any of the three-stage kits in its press release. In this instance, it’s always best to contact the tuner directly to get a proper price quote. Since Noelle is a German tuner, pricing could also differ depending on where the clients are.

The BMW 7 Series doesn’t get as many upgrades as the models below it, but there is one tuner that’s been known to work on the 7. That tuner is Alpina, which technically doesn’t count as a tuner since the German Ministry of Transport actually treats it as an automobile manufacturer. Be that as it may, Alpina presented its take on the 7 Series back in March 2016. The highlight of that program was the engine upgrade on the 7er’s 4.4-liter twin-turbo V-8 engine that nets a total output of 600 horsepower and 590 pound-feet of torque, good enough to help the B7 sprint from 0 to 60 mph in just 3.7 seconds to go with a top speed of 193 mph.

As fancy as the BMW 7 Series has become, the king of this segment remains the Mercedes S-Class. That does make it rather mandatory to have an S Class in this section, doesn’t it? It just so happens that in June 2016, Renntech presented its program for the Mercedes S550 and it packed a number of upgrades on the exterior and engine parts of the luxury sedan. The engine, in particular, was treated to an ECU upgrade that propelled the S550’s 4.7-liter twin-turbocharged V-8 to produce an output of 530 horsepower and 606 pound-feet of torque, an increase of 75 ponies and 90 pound-feet of twist over the standard model. The result allowed Renntech to boast a sprint to 62 mph of just 4.6 to 4.7 seconds, 0.1 seconds quicker than the traditional time for the S550.

The variety is there to give owners of the BMW 750i a chance to pick which upgrade suits them best. That’s something that should make this program appealing. I am surprised that Noelle didn’t do anything to the sedan’s exterior, but especially more to the interior. I would have figured that for a company that counts itself as one of the few tuners of the 7 Series, a few bits and pieces here and there would have been done. But I’m not taking it against Noelle Motors because the tuner is known more for its engine upgrades and on that regard, it’s got enough impressive choices to make it difficult for 7 Series owners.

  • Leave it
    • No exterior and interior upgrades
    • Not even a set of wheels
    • Some might just opt to keep the 750i as-is
