2027 Changes?
I keep seeing about the new M177 EVO flat plane crank engine coming in the 2027 S and GLS' but no chatter about the R and C192s. Kind of curious as we have a 2027 SL55 on order with a June build date.

There will be a complete SL facelift in 2027 for the 2028 model year.
The flat-plane V8 is EURO7 compliant and the companies have until Nov. 2027 to implement the changes. The Euro 7 regulations start on Nov. 2026
The SL43 is not EURO7 compliant and gets killed off and replaced by the SL53. All cars will now be 4matic
Assumed specs subject to change:
Unlike the AMG models the Maybach feels like the SL's of old with its softer suspension, engine and transmission calibration. I heard that this softer tuning maybe expanded to regular SL models as well.

SL65(R231), SL65(R230), 600SL, 560SL(86), 560SL(89),250SL(68),250SL(67), 190SL, 300SL(GW)
Interesting that the SL63E was dropped so quickly. Obviously sales for the R232 are quite weak, and even worse for the SL63E. I fully intended to place an order for the top line R232 but reliability concerns created doubts. The low sales and horrible resale indicate I'm not alone in my caution. The 642HP still seems light in this competitive market.

The ePerformance design has been around for many years, starting with the AMG 63 4 door model.
While the hp numbers sound enticing, the cars are technically complex, very heavy and the performance easily matched by simpler engine designs.
We know from the AMG GT BS, it’s no problem to go above 700hp on these without the mild hybrid.
