Merc has started on road tests of the electric SLS supercar and is still on target for a 2013 launch AMG boss Volker Mornhinweg has told Autocar.
Mornhinweg also revealed that AMG engineers are still confident that the electric SLS will meet all of it's performance objectives: a 0-60mph time of 4.0 seconds with a battery range of around 110 miles.
"We are on target to meet all of our objectives but we obviously have lots of time to fine tune," he said.
AMG's boss was also confident that it would be as exciting to drive as the recently launched petrol version.
"Effectively being four-wheel-drive does alter its character, but our torque vectoring systems give us opportunities to make it as good," he said. "It's important to get the emotional level of an EV right and we have some solutions."
