Mercedes-Benz SLThe 2022 Mercedes-Benz SL is a timed release. Its dramatic entrance will come before the end of 2021. Before its arrival, will you tire of it, or be that much more enthralled?

Previously, we saw SL prototypes drifting in the snow, showing off their all-wheel drive (AWD) capabilities. Now the automaker wants you to see beneath the surface, reinforcing the rigidity of its composite aluminum structure.

If you owned an original SL, it had a space frame with the lowest weight and highest torsional rigidity.

The 2022 SL combines a lightweight composite aluminum chassis and a self-supporting structure. Neither any preceding SL nor the AMG GT roadster provided any part to the new 2022.

“The body shell design team was faced with the overall development of the new SL, starting from scratch, without any existing structure,” said  Jochen Hermann, Chief Technical Officer of Mercedes-AMG GmbH.

“We reconciled the high package demands, while achieving excellent rigidity with a favorable weight, providing agile driving dynamics and exceptional comfort,” Hermann said.

The requirements for the new roadster were more comprehensive scope than its predecessor. The 2+2 layout with 2+2 seats and a number of drive systems created complex challenges. The driving performance characteristics of the brand, plus comfort and safety were all taken into account.

The space frame, the basis of the SL’s success  70 years ago, was very light with high torsional rigidity. However, regular doors were not possible due to their entrance height, which resulted in the original’s gullwing doors.

Today’s frame construction design can cope with tensile and compressive stress. Closed triangles transfer stress to a tubular pyramid at the engine compartment’s end.

Aluminum, steel, magnesium, and fiber composite intelligent material composition ensures the highest possible rigidity in conjunction with low weight in the new SL.

The magnesium instrument panel support, along with the carbon fiber front module cover bridge demonstrates the effort to achieve the best possible diverse material use.

SL production will take place at the Bremen plant where its predecessor was built.

    Those pictures are hot [TMI?].

    True fact: The cross-car beam on the ill-fated GMT200 minivans (Venture/Silhouette/Trans Sport) is a hunk of magnesium – in case you ever need a lifetime supply of firestarters.

    judging the looks of the front end of the prototypes, the replacement SL will bejust as ugly as the current generation. It’s been a sad downward trend for the SL styling from the rounded headlight generations. The Euro frontal pedestrian requirements likely are the cause.

    “If you owned an original SL, it had a space frame with the lowest weight and highest torsional rigidity.”

    Could somebody translate that into meaningful English?
