You can read the whole article below which goes into all the fancy stuff that Porsche does indepth but what caught my attention was their roll bar setup. Instead of just a regular hydraulic roll bar Porsche went and added an electrically actuated roll bar with a motor so that it wont sap power from the engine
No wonder Porsches pwn everything else. The downside is that if there is ever a problem you are fucked with all this complicated engineering and components making repairs very costly

The last generation Porsche Cayenne had a similar system, but it was electro hydraulically-actuated and sapped power from the engine at all times thanks to the always-on pump. Plus, it took a bit of time to react
But for 2019, the Cayenne gets a dedicated 48 volt system whose sole job it is to manage body roll through the electromechanical roll stabilization system. The way it works, as Bittner shows me, is it uses a motor and a three-stage planetary gear reduction to rotate one half of the anti-roll bar relative to the other. Both of these halves, which are rather stiff compared to a conventional sway bar, are mounted to the stationary subframe near the center, and at the end to a link that hooks to the car’s moving suspension arm.
During body roll (which is detected by a number of onboard sensors), one side’s control arm wants to move up (relative to the subframe) more than the other control arm does; to prevent this, the active roll stabilization essentially uses the other half of the sway bar to pull up the control arm on the other side, which yanks the body body down flat.

GLE self-driving features are like 90% of the Model X. Plus, I'm concerned about Tesla's reliability, the crazy cost, and the feasibility of dealing with charging on long road trips. Also concerned about their viability as a company over the long run. Still, they're an option.
GLE is cheaper both to buy and maintain for equivalent trims/levels of performance and I don't see any real benefit from the Porsche (but see some from the Mercedes, like the self-driving features).
I drive a lot so I really value the option of letting the car take over and letting me check my email or whatever.

holy fuck. no wonder europeans laugh at our drivers and driver certification
*I want a car but also want to eat my sandwich and play my guitar while driving it*

Land Rover had active roll bars in 1999. Porsche has given up any pretense of its SUVs as off-road vehicles. Staggered wheels on an SUV? Basically they are now just trying to make the SUVs handle like sports cars.
