As a general rule, if you were to buy a BMW with the purpose of modifying it, you would usually go for a 3 Series, or even a 1 Series, as there are plenty kits out there for them.
Still, that does’t mean aftermarket specialists can’t offer their services and products for the higher luxury models, like the 7 Series.
Hartge is right on that, it seems, as their latest announcement indicates, with a nice new upgrade for the F01 BMW 730d. With the tuner’s product, the power output of the 7 Series is raised from 258 HP and 560 Nm of torque up to 309 HP and 670 Nm.
If you were to compare this to the power levels of the 740d version, you’d see that it’s pretty close, so the question arises: why should you upgrade your ride with an aftermarket kit rather than just buy the same thing directly from the car maker? I’m sure buyers (and there will be buyers) have plenty of reasons. And in a Hartge traditional way, we get to see the kit at work in a nice little video just below.
