SLS AMG Electric Drive (2013–)
The SLS AMG Electric Drive is an upcoming electric version of the SLS AMG
planned for release in June 2013.[47] The vehicle was unveiled
in 2012 Paris Motor Show, with market launch began in 2013.[47][48]
History
E-Cell at
2011 Geneva Motor Show
The
idea of an electric SLS AMG was originally introduced publicly as the SLS AMG
E-Cell prototype in 2010. That prototype is drivable and is powered by four
electric motors that provide a combined 392 kW (526 hp) and
880 N·m (650 lb·ft). The battery is a 400 V lithium battery with a 48
kWh capacity.[49] Other features include pushrod damper
struts, 402 x 39 mm front and 360 x 32 mm rear brake discs made in carbon
fibre-strengthened ceramic, Full-LED headlamps, AMG 10-spoke light-alloy wheels
with smooth-surfaced design, AMG Drive Unit angled towards driver, Nappa
leather in a black/white colour combination at sports seats, performance
leather/alcantara steering wheel and the door linings, centre tunnel.[49]
The
battery came from Deutsche Accumotive GmbH & Co. KG, a joint venture
between Daimler AG and Evonik Industries AG.[50] The drivetrain has been in development
since 2010 as a result of the cooperation between Mercedes-AMG and Mercedes AMG
High Performance Powertrains in Brixworth.[51]
The
vehicle was unveiled in 2011 North American International Auto Show.[52]
[edit]Powertrain
The
SLS AMG Electric Drive will be powered by four electric motors with combined ratings of 552 kW
(740 hp) and 1,000 N·m (740 lb·ft). Each motor can spin up to
13,000 rpm and weighs 45 kg (99 lb). In addition, the transmission
allows each motor to selectively drive all 4 wheels. With this, the SLS AMG
Electric Drive accelerates from standing still to 100 km/h in 3.9 seconds.
[edit]Battery
The
SLS AMG Electric Drive will include a liquid-cooled 400 V lithium-ion
battery rated to 60 kWh. The 548 kg
(1,210 lb) battery pack is made up of 12 modules, each comprising 72
lithium-ion cells. The system was designed as a collaboration between
Mercedes-AMG and Mercedes AMG High Performance Powertrains Ltd.[47]

[edit]Body style
[edit]Engine
[edit]Transmission
AMG SPEEDSHIFT DCT 7-speed dual-clutch semi-automatic
transmission is
connected to engine through a lightweight carbon fiber driveshaft in a transaxle arrangement.[2]Selectable driving modes include
"C" (Controlled Efficiency), "S" (Sport), "S+"
(Sport plus) or "M" (Manual).[53] A
true manual transmission is not available.
[edit]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]
[edit]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).[2]
[edit]Performance
The
SLS AMG is capable of accelerating from 0 to 60 mph (97 km/h) in 3.8
seconds, and can reach a top speed of 211.3 mph (340.1 km/h) (figures
are provisional).[54] In
a Car and Driver test, the SLS recorded a quarter mile
time of
11.7 seconds @ 125 mph (201 km/h).[55]
[edit]Safety
In
the July 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.
[edit]Exterior
The
exterior aluminum body is supplied by Magna Steyr.[56] This
and the CL65 AMG 40th Anniversary Edition are the only roadgoing Mercedes-Benz
with the AMG Alubeam Silverpaint
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.
