I don't get the I4 - what is the target audience?

How is an M139L going to fit in the Emira?

Lengthways, of course... duh

 

[kitkat]

How would a new fuel injection system and electric turbocharger make it not fit?

Edit: a high voltage system is required as well yet those don't weigh very much or include much additional hardware. And even if that version never comes, the 420hp tuned M139 will be a huge step up.

Sure a hotter M139 is a no brainer but the M139L has a completely separate electric drive unit on the other axle with a fairly large battery and a drive shaft connecting the two and a completely different transmission. I'm just not sure how that would fit in the Emira packaging.

Your're referring to the AWD fully hybridized Verision in the C63. That application has an electric motor and two speed gearbox. It's a 400 volt system. A 48 volt system or similar would be appropriate for a mild hybrid version of the M139 in the Emira's application and would be considerably lighter, less complicated and easier to package. Main additional hardware is the 48 volt battery and AC / DC converter. Feel free to fact check; I recall Audi saying their 48 volt system for their electrically turbocharged applications only adds 22 lbs.

Oh yeah I understand all that but presently there's only one application of the M139L like you mentioned in the AMG C63S -- and this is the only configuration of the M139L that exists unless I missed something.

You're suggesting a new variant of the M139 that does not yet exist. Given AMG's agreement with Lotus on not modifying any drivetrains and their business relationship I'm just not convinced that's in the cards before the Emira goes out of production.

I'm clairvoyant. There will be an M139L that is not fully hybridized. This is the debut application and other configurations will follow.

Do you mind telling me when my Emira is going to arrive?

 

[Lotus64]

Well that didn't take long. 2023 C43 to receive M139L paired with 48 volt system. That one was free, I'll have to charge for the next prediction though. .

God damn you are clairvoyant.

I say we string this guy up until he tells us when the Emira gets US approval.

And rather late to the party to give my personal preference which is for the i4. I owned a V6 Evora and didn't like the V6 nor the manual gearbox particularly. The V6 ran out of puff far too early and the gear change was notchy. So for those of us who don't think that the V6 manual is the epitome of driving enjoyment, then it may be that the turbo push and ultra fast gear change of the i4 might be more enjoyable (all this is for recreational road driving, not dailying or tracking). I hope it is more rewarding although the review comments are worrying. Bring on the test drive.

It may also be that the 8 speed box/motor combination is not good for manual-paddle change on the road. That's a lot of gear changing to do. It might only work in auto mode. That might also be a fun drive. I had an extended test drive in an Evora slush box auto and found it rather good as a driver's car. No idea why I ended up in a V6 manual!

In summary I was hoping that i4 might be a rather good driver's car, but I guess I'll find out.

And yes, I have wondered whether just getting an A45 would be more fun than the Emira i4!

I’m in the same boat. (Not an evora owner). No slush box, but this car must be a DCT for me.

 

[Jdmc21]

There's no replacement for displacement; however the title of this thread is unnecessarily negative. The I4 still has its place in the line up and will be a great drive, regardless of the V6. And the prospect of rowdier I4 versions is very exciting, especially the M139L.

Wasn’t that adage created because GM couldn’t make reliable turbos in the 70s?

I’d rather have a modern turbo 6 than a Cadillac 16 in any car I’m driving.

The M139 used in Emira is a transverse version, while the M139L versions are for longitudinal usage. There are probably other size differences as well since the electrical turbo needs a 48V system that requires more space etc.

The M139 is used in transverse and longitudinal applications. The same will apply to the M139L.

I'd take the a modern turbo Cadillac 16 over either of those options....
