Anybody else with an A5 (2012+) Beetle?

I have a 2017 Beetle, and I'm planning the future mods for this car, looking for ideas beyond careful driving, inflating up, etc. I'm looking for subtle things that help, so no boat tails, etc LOL

Looking first at aero mods. Air dam and side skirts seems obvious, but I'm not sure if the A5 would benefit from a roof spoiler the way the classic Beetle or 98-10 New Beetle would. It has the stock turbo spoiler, and from what I'm reading it does actually help aero. Also considering fender vents to clean up those small vacuum areas.

With the intercooler and what not, I'm not sure grille blocking is very safe, but I'm looking into that.

Next, I'm looking into setting up a system where the alternator is electrically disabled until it hits a certain voltage. I'd add flexible solar panels to keep above that voltage as much as possible, but still have an alternator that can keep it going at night and under heavier electrical loads. I'm not quite sure what voltage to cut off at and what to use to accomplish that.

Also wondering if it would be worth it to open up the exhaust and intake.

Hopefully somebody else will have worked with one of these cars, but if not I'll have to blaze a trail

I haven't seen any of the newer Beetles on the site, but all the normal aeromods will work for you.

Do you have a Scangauge or other OBDII gauge where you could watch intake temperatures? With that you could start blocking some of your front grill off and adjust as necessary.

Using Trip Computer

I don't have a Scangauge, as I usually use my trip computer. How about the Bluetooth OBD II interfaces? Will the torque app give me the intake temp?

That's the coolest modern beetle I've ever seen.

Normally they come in goofy-green or sundried-lemon.

Nice work with the stripes. Fuel economy doesn't matter now

For economy mods, I've heard that chip-tuning works really well on those.
2003 Renault Scenic - 30% more power with no loss in fuel economy.
1991 Toyota GT4 - more economical before ST215W engine-swap.
previous: Water-Injected Mitsubishi ~33% improved.
future - probably a Prius

Wrong year but close, maybe one of those rear spoilers at the lower base of the rear window would help.

VWVortex.com - Rear roof spoiler - has anyone seen any of these?

Like this one below.
