The Mercedes-AMG SL launched with two levels of V8 potency, but now a four-cylinder advantage is (maybe) abutting the calendar with the Mercedes-AMG SL 43. We say maybe, because Mercedes still isn’t abiding if the U.S. will get the SL 43. A aggregation agent beatific us the afterward statement:
“The Mercedes-AMG SL 43 is currently still beneath application for the U.S. market. We do not accept any capacity to allotment apropos U.S. availability at this time. We attending advanced to ablution the iconic all-new AMG SL with the Mercedes-AMG SL 55 and Mercedes-AMG SL 63, which will both access in U.S. dealerships in backward spring.”
While we delay for Mercedes to accomplish its apperception up, we’ll acquaint you all about this new archetypal that may or may not be advancing here.
The SL 43 uses the M139 agent out of the CLA 45 that we already apperceive and love, but there’s an electric aberration this time. Instead of a acceptable turbocharger, the SL 43 is able with an electric bankrupt gas turbocharger, the aboriginal of its affectionate in a alternation assembly car. Mercedes provides a abundant description of how it works, so we’ll adhesive it beneath for you.
“An electric motor about four centimeters attenuate is chip anon on the turbocharger shaft amid the agent caster on the bankrupt ancillary and the compressor caster on the assimilation side. Electronically controlled, this drives the shaft of the turbocharger anon and appropriately accelerates the compressor caster afore the bankrupt gas beck starts to drive it conventionally.”
This agency bigger burke acknowledgment and beneath lag amid aback you tap into the burke and aback the alleged aloft dispatch occurs, aback there’s no cat-and-mouse for bankrupt gases to circuit up the turbocharger. Mercedes additionally says to apprehend added torque at lower revs, and aback it doesn’t crave bankrupt gas to drive the turbine, it’s able to advance addition burden alike aback you’re off the throttle. So, aback you hop aback on the gas pedal afterwards lifting, you should apprehend to accept consistent, actual and anticipated acceleration.
Mercedes is able to drive this electric turbocharger via the car’s 48-volt electrical system. The turbo bureaucracy is acquired from technology acclimated by Mercedes’ F1 team, and Mercedes says it “is a absolute acquired of the development auspiciously acclimated by the Mercedes-AMG Petronas F1 Aggregation for abounding years.”
Moving above the agrarian tech, the high-tech agent produces 381 application and 354 pound-feet of torque. The belt-driven amateur architect that functions as a mild-hybrid arrangement can accommodate an added 14 application for abbreviate bursts. We’ll additionally agenda that this is the aboriginal time this agent is army longitudinally instead of transversely, aback it’s commonly been acclimated in front-wheel-drive layouts. Meanwhile, the SL 43 is rear-wheel-drive-only. Mercedes additionally akin this agent up to its nine-speed multi-clutch transmission. Using barrage control, Mercedes says it’s acceptable for a 0-62 mph dart in 4.9 abnormal and a top acceleration of 170 mph.
You’ll be able to acquaint the SL 43 from added SL models from its “SL 43” badging in back. However, Mercedes additionally fits different advanced and rear aprons to the four-cylinder model, and the cloister bankrupt appearance annular outlets instead of angular bankrupt tips. It’ll appear accepted with 19-inch wheels, but you’ll be able to optionally add 20-inch or 21-inch wheels. Passive dampers are standard, but you can optionally add AMG’s adaptive dampers. Rear-axle council is optional, and the account of account is absolutely amaranthine in the accepted Mercedes fashion. We doubtable a lower barrier weight will be account for bigger handling, but Mercedes did not accommodate a weight with this antecedent announcement.
Pricing and availability are both big questions for the SL 43. If we do ultimately get it here, apprehend it to appear in cheaper than the SL 55 and way cheaper than the SL 63, both of which still don’t accept official prices.
