If this is truly what’s happened, a broken drive shaft, then it calls into question the thesis that JUBU are claiming weak areas just to sell more parts. They also claim weak pistons, rods, valves, flywheel and clutch……….

Those driveshafts are expensive! With the conversion to U.S., and I believe there's a 25% tariff on this? Including shipping, that would be an almost $8,000 cost. So if you get these, what does that do to the transaxle?

Adding power always tends to be expensive because it often requires upgrading other things to handle the added power, but this could get expensive fast depending on how you drive I guess.

Welllllll! I broke an axle or something went to test quarter mile on the 93 octane tune (feels awesome BTW much more punch) but launched at right around 4000 and immediately the car just felt like it was in neutral and now I can fully let out the clutch in gear and you can hear something rotating and car doesn't stall.

So I know most of us know this but DO NOT clutch dump or even soft launch these cars. Waiting on the tow truck now. Really hope it's not internal to the trans but I'll get it sorted regardless.

Sorry to hear. My axle also snapped. Thankfully it was an easy fix covered under warranty!

I guarantee you it won't be for anyone with a piggyback. Obviously, you can remove it, but that seems like a lot of work. What's weird is this simply hasn't been the case on previous v6 applications. Makes you wonder if they skimped on the axle source this go around for the Emira?

I'm not sure why this seems to be an Emira problem, but the axle is the same part number as the Evora

 

[Coreyalert3]

It's the axle!

 

[jp129]

Unfortunate that it broke, but glad it's just an axle and nothing else.

 

[F1 SML8R]

@Six Speed Stephen That's my point, it should be identical and physically it likely is. It's the manufacturing source that's in question. I have noticed silly stuff on my Emira (washers, bolts, clips, etc.) where clearly "price" was the key driver in selecting a source. I don't remember these miscellaneous items being that cheap in quality in my Evora.

The piggyback is a 10-15 minutes job to install / uninstall for the V6. ( 4 electrical connectors to unplug then 2 connectors to replug. ) Easy like 1-2-3 located on top of the engine bay.

If you do not make any hole into the firewall to pass the OBD2 cable, my guess is there is no evidence proof for the dealer to refuse to honor the warranty.

In my case I think just swapping the axle makes sense. Warranty work could get held up and if I had an axle on hand I could be back at testing this thing today easy. Let me go to Autozone and see if they have them

Yeah that's Auto Europe's store I've dealt with Don a bit in the past but now I have a local Lotus Dealer need to check with them and see if they have one in stock I'll do that now. Bell and Colvill has been a good resource overseas and in the past could save a lot of money getting parts that way without paying the US markups

Did both side axles break or just one?

 

[chirowolf]

Maybe a dumb question but is there a map "0" if I want to run the stock tune?

Yes!

Bell and Colvill ask 899 british pound = 1 215$US.

In case the warranty route does not work out, this may be worth checking oit and comparing…

Good luck,!

 

[Emira Fan]

wow, that's clean break. If everyone starts bring cars in for axel snaps, Lotus will ask dealers to start dumping the data logs, and start flagging cars.

[ but the axle is the same part number as the Evora]
Evora is lighter than the Emira, right? Have people been running 50 extra HP in the Evora's without issues?

Maybe the part just can’t handle the additional weight of the car
