Charger? You need to move up to the Scatpack 485 HP to beat it. Anything less-forget it.
Corvette? Yep... Camaro? maybe.
Mustang? Some
What else? (That you might see once a month?)
Please let me know. I am curious.
But again...its more than fast enough for me 5.4 sec 0-60
0-60 is not everything. It is only for people who buy cars based on the spec sheet. BRZ / GR86 is a slow car by modern standards, that's how they can keep the MSRP low. Toyobaru aimed to make it slightly faster than MX-5 when they built it. It is slower than any other enthusiast car on a straight line, which doesn't make it a bad vehicle, it's still a great sports car.
Teslas get 2.x seconds 0-60, that doesn't make them better sports cars, they are just fast microwaves on 4 wheels.
3 three-cylinder engine is smaller, and lighter, which means the car will be lighter and more fun to drive. The front end will be more responsive to steering inputs. The weight balance will be closer to 50:50.
Turbo engines offer more torque, meaning that it will be more fun to drive. It will be faster without doing any mods.
It might be fast enough for you, but that doesn't mean it is better.
For tuners, turbo > naturally aspirated, because you get a lot more out of your engine with simple mods.
Long story short, it is the right move for Toyota, especially for a car designed for the tuner crowd.
P.S - Charger R/T with a fleet engine would shred the GR86 if 0-60 is all you care about, you don't need to move up to Scat Pack. As much as I hate the EcoBoost Mustangs and 4-cylinder Camaros (because they are meant to have a V8 engine), they are also faster. Sorry for the bad news, but your car is slower than you thought.
