I have a 2.0T and I got a 3.3TT loaner, so I wanted to compare the two and I couldn't find the comparison thread.
So I think the 3.3TT is objectively the better engine. Reviewers say the 2.0T engine is adequate and the 3.3TT is a gem, but more than that, the 3.3TT rounds out the entire car and brings out its potential. The handling under speed, the transmission logic, the speed, the responsiveness, and the car's ability to handle it all come together.
The biggest difference is how much more responsive the bigger engine is from a stop. It pretty much feels naturally aspirated. With the 2.0T, there is turbo lag that holds the car back from moving faster than creeping speeds for almost a second. This is particularly bothersome in turns from a stop, since it makes the acceleration thrust hit right in the middle of the turn instead of getting it out of the way early on. So you get all the G forces at once abruptly. In turns you slow down and then accelerate into, the bigger engine can handle the speed at any RPM, but the smaller engine downshifts in the middle of the turn, briefly cutting power, unless you always do manual shifting before the turn.
Yeah, it's aggressively fast. It feels less smooth to me actually because of how aggressive the bigger engine is even in comfort mode, but I may just not be used to regulating the throttle. A weird downside for me is that it's so fast off the line that it lifts the front upwards, which I don't like. But then just go slower lol.
Some people have mentioned the engine weight difference, and I think it's so minimal that you can't notice it unless you drive them hard and back to back. The bigger engine has a bit less willingness to turn, but I only notice it in roundabouts. It's not worth consideration.
Difference in suspension is also not a big deal. The bigger engine stiffer suspension is a bit firmer in that bumps you already feel in the 2.0T are more noticeable, but they're not so different that it changes your impression of the bump from like noticeable to harsh and annoying. I'd say the suspensions are in the same tier of firmness.
Brakes I can't tell a difference at all in performance or feel, but I like gradually braking and I don't brake hard or aggressively much. Maybe the Brembos would be better in an emergency situation. But otherwise probably not worth the downside of the deposits on the brake rotors.
So overall, the 3.3TT makes the G70 a better car. But now the downsides outside of that. Gas mileage is abysmal. I can't get my 2.0T to get below 20 mpg in reasonable driving (no idling) even if I drive all surface streets, stay in sport mode, or even use sport mode on the highway. But for the 3.3TT, I'm getting like 16 mpg on surface streets. I can physically see the difference in the gas meter over several minutes lmao. With the small tank, I could imagine this being very annoying. In my case, a 3.3TT would've been $6000-7000 more expensive than my 2.0T, or about 15 precent more expensive. In my case, those downsides probably aren't worth it... Or at least I'm convincing myself of that lol.
