2022 Mercedes-Benz SL Beauty's Skin Deep

The 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.

With a father who owned a dealership, I literally grew up in the business. After college, I worked for GM, Nissan and Mazda, writing articles for automotive enthusiast magazines as a side gig. I discovered you could make a living selling ad space at Four Wheeler magazine, before I moved on to selling TV for the National Hot Rod Association. After that, I started Roadhouse, a marketing, advertising and PR firm dedicated to the automotive, outdoor/apparel, and entertainment industries. Through the years, I continued writing, shooting, and editing. It keep things interesting.

    "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?

  • Jalop1991 In a manner similar to PHEV being the correct answer, I declare RPVs to be the correct answer here.We're doing it with certain aircraft; why not with cars on the ground, using hardware and tools like Telsa's "FSD" or GM's "SuperCruise" as the base?Take the local Uber driver out of the car, and put him in a professional centralized environment from where he drives me around. The system and the individual car can have awareness as well as gates, but he's responsible for the driving.Put the tech into my car, and let me buy it as needed. I need someone else to drive me home; hit the button and voila, I've hired a driver for the moment. I don't want to drive 11 hours to my vacation spot; hire the remote pilot for that. When I get there, I have my car and he's still at his normal location, piloting cars for other people.The system would allow for driver rest period, like what's required for truckers, so I might end up with multiple people driving me to the coast. I don't care. And they don't have to be physically with me, therefore they can be way cheaper.Charge taxi-type per-mile rates. For long drives, offer per-trip rates. Offer subscriptions, including miles/hours. Whatever.(And for grins, dress the remote pilots all as Johnnie.)Start this out with big rigs. Take the trucker away from the long haul driving, and let him be there for emergencies and the short haul parts of the trip.And in a manner similar to PHEVs being discredited, I fully expect to be razzed for this brilliant idea (not unlike how Alan Kay wasn't recognized until many many years later for his Dynabook vision).
  • B-BodyBuick84 Not afraid of AV's as I highly doubt they will ever be %100 viable for our roads. Stop-and-go downtown city or rush hour highway traffic? I can see that, but otherwise there's simply too many variables. Bad weather conditions, faded road lines or markings, reflective surfaces with glare, etc. There's also the issue of cultural norms. About a decade ago there was actually an online test called 'The Morality Machine' one could do online where you were in control of an AV and choose what action to take when a crash was inevitable. I think something like 2.5 million people across the world participated? For example, do you hit and most likely kill the elderly couple strolling across the crosswalk or crash the vehicle into a cement barrier and almost certainly cause the death of the vehicle occupants? What if it's a parent and child? In N. America 98% of people choose to hit the elderly couple and save themselves while in Asia, the exact opposite happened where 98% choose to hit the parent and child. Why? Cultural differences. Asia puts a lot of emphasis on respecting their elderly while N. America has a culture of 'save/ protect the children'. Are these AV's going to respect that culture? Is a VW Jetta or Buick Envision AV going to have different programming depending on whether it's sold in Canada or Taiwan? how's that going to effect legislation and legal battles when a crash inevitibly does happen? These are the true barriers to mass AV adoption, and in the 10 years since that test came out, there has been zero answers or progress on this matter. So no, I'm not afraid of AV's simply because with the exception of a few specific situations, most avenues are going to prove to be a dead-end for automakers.
  • Mike Bradley Autonomous cars were developed in Silicon Valley. For new products there, the standard business plan is to put a barely-functioning product on the market right away and wait for the early-adopter customers to find the flaws. That's exactly what's happened. Detroit's plan is pretty much the opposite, but Detroit isn't developing this product. That's why dealers, for instance, haven't been trained in the cars.
  • Dartman https://apnews.com/article/artificial-intelligence-fighter-jets-air-force-6a1100c96a73ca9b7f41cbd6a2753fdaAutonomous/Ai is here now. The question is implementation and acceptance.
  • FreedMike If Dodge were smart - and I don't think they are - they'd spend their money refreshing and reworking the Durango (which I think is entering model year 3,221), versus going down the same "stuff 'em full of motor and give 'em cool new paint options" path. That's the approach they used with the Charger and Challenger, and both those models are dead. The Durango is still a strong product in a strong market; why not keep it fresher?
