Vonnen’s Porsche 911 Does The Unthinkable — Carmudgeon w/ Jason Cammisa & Derek Tam-Scott — Ep. 205

from The Carmudgeon Show · host Hagerty Media

Air-cooled Porsche 911s are wonderful to drive. With charming handling characteristics, bank vault build quality, and often cheerfully entertaining powertrains, it’s no surprise that they’re a hot commodity in the collector car marketplace with millions of fans around the world. There is one problem, however……by modern day standards, they’re SLOW! === This episode is sponsored by Battery Tender.

Vonnen has taken a standard 1988 Porsche 911 Carrera 3.2 G50 and added batteries and a sandwich motor between the engine and flywheel that adds nearly 150 HP and 130 TQ to the standard car. This isn’t Jason’s first rodeo with a Vonnen-modified 911, as his first experience began with a similarly-equipped 991 Carrera Coupe he tested nearly 10 years ago with Road & Track. Spoiler alert - adding power to an already-fast Porsche doesn’t yield quite the same joy as an air-cooled 911 does with a fraction of the power. How does adding electrons alongside the traditional flat-six change the 911 experience? Can a hybrid system of this nature change the way we interact with classic cars forever? Well one thing is for sure - with only 150 pounds of additional weight and clever integration, Vonnen’s system adds a lot less complexity and a lot more enhancement to the out-of-the-box, air-cooled 911 experience than you might imagine.
