C8 is faster and much heavier. 718 is ~3100 lbs or less and the C8 with the Z51 package is ~3500 lbs and more. Sound wise, the C8 will sound better than the turbo 4, but when compared to the flat 6, the C8 and 4.0 GTS sound equally great. Theoretically, the C8 competes against the 911 and would objectively beat the 718 in nearly all objective metrics on track. But people don’t buy Porsches for the spec sheet.

They’re vastly different cars. You can enjoy both, but it all depends on what you’re looking for. You can buy a C8 with the Z51 pack at the price of a base and S 718 with options. Both are fun on backroads. Both can be driven daily if you wanted.

I linked a very thorough video comparing the C8 and BASE 718. Personally, I would choose the 718 10 out of 10 times. A 3000 lb mid engine sportscar with a small footprint and Porsche engineering for under $100k is a rarity in itself. The fact that it punches above what its spec sheets would suggest is the icing on the cake.

I had the same dilemma and ended up choosing the Boxster S. The Vette sounded great and had super acceleration, but the Boxster felt more “alive,” to me. The steering feels perfect and so connected, throttle response, the suspension all felt lighter and more precise. The Vette felt heavier and more awkward to me. I would recommend stepping up to the 2.5L S model, if not the 6 cylinder GTS, the 2.0L didn’t lack In performance but felt a little “thrashy” to me.

I also preferred the cockpit in the Porsche, classic and well laid out. The Vette felt a little gimmicky with the center console, but maybe I’d have gotten used to it.

Just because no one else has mentioned it - the Porsche will save a bunch of money on gas, it’s actually quite economical.

One last thought- I struggled with the idea that the Vette has so much more power. The truth is, either car has more power than you will ever use on public roads. I’d pick the one that you feel best driving

I’ll play the other side. Currently on my 2nd 2023 1LT Z51 C8. Been debating switching to 718 as well. Where I struggle is the price difference between the two. It’s really hard to beat the corvette value wise. I’ve absolutely loved mine. 0-60 it’s fantastic and they handle great with mag ride + Z51 suspension. One major perk for me that I haven’t seen mentioned is all C8’s have removable hard tops which can be stowed in the trunk. You can fit two sets of golf clubs back there as well (if you leave the top on). I love the interior of the C8, it’s extremely driver focused, latest tech with full digital dash. I have no fit and finish issues with it at all. I’d argue the C8 looks much more expensive/exotic than a 718. As others have stated they are very different cars and it depends what kind of driving experience you’re looking for. It would just be difficult for me to lose that straight line acceleration when switching to a price comparable 718 model. Can’t go wrong either way!!
