The Mercedes-Benz SL-class is a perpetual favorite among the wealthy and glamorous, and with the current model, the Germans got the formula right again. In production since 2001, the R230 SL has already gone through two face lifts. The soft, outdated look of the original design has been sharpened, albeit at the expense of the overall stylistic balance of the car. It's time for Mercedes to get busy putting the next generation into production.
And so the last update done for 2009 will likely be the end of the road for this SL; these photos show that the next generation is well along in its development. While the basic concept of the SL will remain unchanged, there will be a lot of updates under the skin. Most important, the awesome V-12 engines, a 6.0-liter and a twin-turbocharged 5.5-liter, will get the bullet, and the naturally aspirated, 6.2-liter AMG V-8 will be gone as well.
The AMG version of the next SL will instead be powered by a turbocharged 5.5-liter V-8 which will likely produce 563 hp and 553 lb-ft of torque, says Henner Lehne, analyst at CSM Worldwide in Frankfurt, Germany. Lehne expects M-B to downsize the engine portfolio, with the three non-AMG versions that will launch initially powered by V-6 engines. Two naturally aspirated engines will make 241 hp and 311 hp, while a turbocharged V-6 is expected to turn out 382 hp—as much as the current SL550’s 5.5-liter V-8. Mercedes is working on engine stop/start systems as well, but a full hybrid is far off, if it comes at all.
Under the skin, the next SL will share many components with the E-class; outside, the look will remain similar to the current model. "Mercedes needs to be careful the SL doesn't come too close to the SLS AMG," says Lehne. Chief designer Gorden Wagener, fond of experimental styling elements, will have to exercise significant restraint if he wishes to preserve the SL's character.
For a while, Mercedes-Benz toyed with the idea of returning to a conventional softtop, somewhat more appropriate for a vehicle that is rarely used as a year-round daily driver outside of temperate climes. But in the end, Mercedes decided to keep the retractable hardtop, which has become somewhat of an SL trademark.
We expect the SL to come with all the electronic wizards—crash-prevention tech, night vision, and lane-departure warning systems, for example—for which modern Mercedes vehicles have become known. Taken from the vast corporate parts bin, these electronics will aim to make the next SL, due to be launched in the third quarter of 2012 as a 2013 model, as safe and convenient as it is glamorous.
