The Mercedes-Benz SLS AMG (C197 / R197) was a front-engine, 2-seater luxury, limited production supercarautomobile developed by Mercedes-AMG of German automaker Mercedes-Benz and was the first Mercedes-Benz automobile designed in-house by AMG.[1] The car, which has gull-wing doors, was the successor to the Mercedes-Benz SLR McLaren and was described by Mercedes-Benz as a spiritual successor to the Mercedes-Benz 300SL Gullwing.[2] SLS stands for "Sport Leicht Super" (Sport Light Super). The Mercedes-Benz SLS AMG was assembled in Sindelfingen, Germany.
The SLS AMG is an iconic vehicle that represented firsts, mosts, and lasts. It was the first Mercedes-Benz designed and built from scratch entirely by AMG, which was given a clean sheet to execute and build its own car design from the ground up.[3] Upon its introduction the SLS AMG's 571 PS (420 kW; 563 hp) M159 engine was according to AMG "the world's most powerful naturally aspirated production series engine" ever produced.[4] The SLS AMG was also Mercedes-Benz's last naturally aspirated engine. With the passing of the SLS AMG's M159 monster engine, and the less potent version used in the C63 AMG (the lower output M156 version), Mercedes-Benz has no remaining naturally aspirated engines in its production lineup.[5] To quote one publication, "The years of the naturally aspirated V8 brutes are over, with Mercedes AMG adopting the downsizing trend." [6] However, Mercedes could not part with this remarkable engine entirely, so when it came to its GT3 race car, it elected to stick with its top of the line, naturally aspirated 6.3 litre engine.[7]
The vehicle was unveiled at the 2009 Frankfurt Motor Show, and sales commenced in mid-2010 in Europe[8] and in mid-2011 in the United States.[9] Mercedes presented an electric version of the car, the SLS AMG Electric Drive, at the 2012 Paris Motor Show. Production ended with the SLS AMG GT FINAL EDITION in early 2014.[10]
The SLS has been owned by many celebrities, including Eddie Murphy, Arnold Schwarzenegger, Al Pacino, Floyd Mayweather, Boris Becker, Mark Wahlberg, Roger Federer, Slyvester Stallone, Tom Hanks, and Christiano Ronaldo, as well as a number of "car guy" celebrities, such as Jay Leno and Jeremy Clarkson, but perhaps most impressively, by premier racing drivers, among them Lewis Hamilton, and it was developed with the assistance of David Coulhard.[11]
The SLS AMG was followed in 2014 by the substantially less expensive, and less powerful, Mercedes-AMG GT.[12]Designed to compete against the Porsche 911 and Audi R8,[13] it relies on forced induction for its power and is available as a 462 PS (340 kW; 456 hp) GT and 510 PS (375 kW; 503 hp) GT S.[12] AMG/Mercedes does not plan to replace the SLS any time soon, with AMG head Tobias Moers being quoted as follows in 2015: "Moers was adamant in reiterating that a true replacement for the modern Gullwing is not yet on the radar. 'Honestly, there's no [Mk 11 SLS] program running. Our homework for the next years is so much, so we took the decision to not replace directly the SLS because SLS has to stand by its own and the Gullwing is an iconic car.[...] If it takes 50 to 60 years to have a Gullwing replacement coming out of the 1950s then we can wait a few more years' [to replace the SLS Gullwing]."[14] Moers was also quoted as follows: "Speaking to Autocar at the (2015) Geneva Motor Show, Mercedes-AMG boss Tobias Moers confirmed that the company has no plans to create a new supercar to replace the SLS. According to Moers, Mercedes is 'not in that league' at this moment in time." [15]
Design
The SLS AMG was designed to be a modern 300SL Gullwing revival by Mark Fetherston from October 2006 to April 2007.[16][17][18] The SLS AMG has also adapted the feature of wing doors that swing open upwards on gas struts, and must be closed manually as AMG engineers against the 90 pounds (41 kg) that auto-closing systems would have added to the car.[9] In case of a roll-over, the doors can be fully detached to allow the occupants to leave the vehicle
Although there is some overlapping in price and performance, the lighter SLS AMG is considered more of a sporty track-oriented car, compared to the Mercedes-Benz SL which is a more autobahn-focused grand tourer especially with its optional V12 engine.[19] Compared to the SLS AMG Roadster, the SL is a hardtop convertible with technological and comfort amenities, and it also has available heated and cooled seats with a massage function.[20] The SLS AMG has also been said to be one of the cheapest cars on the market with an unusual door design.[21]
The Gullwing version of the SLS AMG has won a number of design awards, including the 2010 red dot "best of the best" award, the iF product design award 2010 for the "Transportation Design" category, and the AUTO BILD Design Award 2010 as "Europe's most attractive car.".[22] It is also the only automobile to have won the gold Design Award of the Federal Republic of Germany.

AMG SPEEDSHIFT DCT 7-speed dual-clutch semi-automatic transmission is connected to engine through a lightweight carbon fiber driveshaft in a transaxlearrangement.[2] Selectable driving modes include "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) or "M" (Manual).[24] A true manual transmission is not available.
Brakes
Standard brakes are 390 mm (15.35 in) (front) and 360 mm (14.17 in) (rear) cast iron disc brakes with 6-piston aluminium (front) and 4-piston (rear) calipers. Optional on the SLS AMG are carbon-ceramic disc brakes. 402 mm (15.83 in) discs with 6-piston aluminium calipers (front) and 360 mm (14.17 in) discs with 4-piston calipers (rear). These brakes provide increased stopping power with a 40% weight reduction compared to the standard brake system.[2]
Environment
The fuel consumption of the SLS AMG is around 13 L/100 km (22 mpg-imp; 18 mpg-US) combined driving according to (NEDC, provisional figure).
Performance
The SLS AMG is capable of accelerating from 0 to 62 mph (100 km/h) in 3.8 seconds, and can reach a top speed of 196 mph (315 km/h) (figures are provisional).[25]The supercar can also perform a quarter mile time of 11.7 seconds at 125 mph (201 km/h).
Safety
In the June 2010 issue of Car and Driver magazine, safety specifications were revealed pertaining to the safety of the SLS AMG's gullwing doors. Ten to fifteen milliseconds after a detected rollover, explosive bolts situated at the top of the door frame fire and bell cranks separate the doors from the car for easy exit during a serious accident. An anti-locking system and a 3-stage ESP are standard.
Exterior
The exterior aluminum body is supplied by Magna Steyr.[27] This and the CL65 AMG 40th Anniversary Edition are the only roadgoing Mercedes-Benz with the AMG Alubeam Silver paint available, at an extra cost of €11,900 in Germany. Other colors include both metallic as matte colors, such as Designo Magno Kashmir, the matte paint known from the SL63 AMG IWC edition.
The SLS AMG has a rearwing which will extend at high speeds for stability and handling, and when braking.
