[Mr.Q]

Reading articles and pieces from different sites got me mixed up about whether the engine in the Q30 is turbocharged or supercharged. As of know is that it will have a 2.5L four cylinder with one single electric motor making it a hybrid. But what do you think would be better for it to be supercharged or turbocharged and why?

 

[Jevlan]

Both are similiar to achieve performance but is different the way it works. It all comes down to power delivery. The power range I find is different for the two and how you tune it makes the biggest difference. Personally I would prefer a turbo charger because of the power band.

 

[Infiniti Q30]

At this point I would think they will be using the turbocharger since Infiniti will be sharing most of its components through Mercedes. Since they have already have a well produced four cylinder it would be perfect for the Q30 chassis.

 

[Mr.Q]

I understand most of the technologies will be shared from the existing Mercedes vehicles but the Q30 might be different and I think it should be to separate itself. Supercharging might be useful for a linear power band to use and I feel as if turbo is geared more toward efficiency. But the main thing is the direction Infiniti wants to go. Both should be able to deliver power no questions asked.

well don't forget about the hybrid electric motor. these usually would help make a huge amount of torque that four cylinders usually lack and with the combination of a turbo or charger your really have the best of both worlds.

don't superchargers usually have the annoying whining sound. I would be be thrown off by it. turbo is for me ; )

 

[Jevlan]

So far infiniti only has giving out a horsepower number and no torque value. If it is the same transplant from Mercedes then the torque should be almost identical to the horsepower.

 

[Infiniti Q30]

One thing I forgot to mention is, as important as the horsepower is you need the best best to deliver the power which is the transmission. What do you guys think it would be like with the continous variable transmission?

CVTs are DIRTT. If Infiniti wants the Q30 to have any credibility whatsoever against its sportier competitors from Audi, BMW or Merc it better have proper gears and at least a DCT option. Otherwise Macan..

 

[GeraldHomes]

From what I heard about CVTs is that they are good for towing and great for guiding towards preserving fuel. The DCT on the other handle would give a sportier feel I would imagine.

Its very rare for manufacturers to use superchargers. I'm going to bank on the turbo.

there are situations where it's needed. for example if you need great amounts of power when moving from a stop, a supercharger can do that well enough, but turbochargers need the engine it's mount to to reach a higher RPM range to actually do it's job. Example of this is the QX60 Hybrid.

 

[trals]

There are cars that are turbocharged that have virtually no lag or delay.

Just goes down to the type of turbocharger - type of motor - and the tune.

I actually find that it's mainly tuners that add turbo's to their stock engines that experience turbo lag, usually when done by the car maker there's very little to no turbo lag. I remember reading somewhere that some new turbo engine is coming out that will have NO turbo lag.

 

[trals]

I see what you mean but I have driven stock cars that have some turbo lag. Usually older turbo cars. The new generation of cars virtually have no turbo lag.

 

[Infamy]

I haven't experienced too much with older stock turbo cars but the newer ones sometimes it is so seamless you don't even realize there is a turbo charger. I find that it is a case of the size of the turbo, usually with smaller ones and the tune makes it seamless and no lag.

 

[Jevlan]

I have faith in infiniti for putting a turbocharger along with the motor to make it more efficient and powerful. But I still think that there might be a few updates on the ecu to have the best running map for the vehicle. Even other similar vehicles have gone through flash updates to meet greater numbers for mileage.

It is rare I know but there are still manufacturers out there still using the superchargers. Audi recently has started using the supercharger again on their 2013 S4. it is a supercharged 3.0L V6 but looking at the specifications it is obviously geared towards performance more than anything.

If you had a choice which one would you guys choose to go alongside the motor?

 

[GeraldHomes]

given the option I would pick the turbo over the supercharger but I wouldn't mind testing out the supercharger to get a feel for the difference in starting off the line.

seems like superchargers were a thing of the past and more common on domestic type vehicles than asian imports.

If I remember correctly, Audi started in the b8 generation (2007-2015) with the 3.0T that was actually supercharged

Volvo, Jaguars also still use superchargers
