I wonder what its torque curve will look like.

Even if I'll never even think about buying one, more 4-cylinder turbos are always a good thing.

More factory turbos = more turbo R&D = better turbos. Everybody wins!

Only available with 2 pedals and it spends most of its life in front-wheel drive?

The variables influencing the torque split ratio are vehicle speed, lateral and longitudinal acceleration, steering angle, speed difference between the individual wheels, selected gear and accelerator position.
I'll pass.

I am curious to see how the power delivery is with that much HP and torques and only 2.0L.

Torque curve will be the following: 4000rpm - noneofit / 4500rpm - allofit

Well if they're running 26psi that suggests the turbo isn't going to be all that big. And since its a benz I'd be surprised if it wasn't something twin scroll. So there is hope for it yet.

But its still a 50+k sedan. Most of us can't afford it lol. Who cares

It is twin scroll according to the press release.

2.0L + twin scroll + EFR-like turbo = winning. I'm thinking it's probably 6258-sized if it's making 350hp@26PSI.

Probably much smaller. Remember this is a larger engine with a head that flows much better than ours and you can make that much at the wheels with a 6258 on our engines at 26psi.

Yeah but take into account all the OEM intake/exhaust parts choking it down.

Or so I'm guessing.

FTFY

But seriously. On the track? Awesome. On a long windy road? Awesome. Doing 3 MPH on the freeway in bumper to bumper traffic?

you'd rather have a manual in 3mph bumper-to-bumper?

Objectively and from a purely rational perspective, I can't argue that a PDK is superior to a 3-pedal gearbox on a racetrack. However, a car like the AMG CLA (or my M3) is going to spend somewhere between 0% and 1% of its lifetime on a racetrack. My preference will always be a 3-pedal gearbox for subjective reasons.


After all, car purchases and ownership are almost never purely rational and objective or we would all be driving Pontiac Vibes and Honda Fits.

While I agree with the bolded part I do not necessarily agree with the second part. I think accounting for how much fun your car will be and how much it will make you smile is perfectly rational and objective. Happiness is the ultimate utility and should be considered in respect to every decision we make. However, you need to consider not just immediate satisfaction but the satisfaction over the entire life of the purchase/decision.

I don't know, I got to spend quite a bit of time driving my buddies '10 M3 with the DCT box..........I thought it was fantastic. If I were in the market to drop that kind of coin, even on a car that would be 99% DD, I'd still go for the DCT.

Remember, a turbo doesn't know what size an engine is. It only cares about flow and pressure ratio. 26 psi means a very high pressure ratio. The higher the pressure ratio, the later a turbo tends to make full boost.

I want to see the RPM it makes 80% of max torque.

I understand that but a larger engine that is atleast of the same efficeincy of a smaller engine will make more power at the same psi on an identical turbo. That was my point.
