Mercedes SLS AMG E-Cell (2010): the electric SLS

Following the unveiling of Tesla's updated Roadster 2.5, Mercedes is showing off its iteration of an all-electric sports car: the SLS AMG E-Cell. While the regular SLS pumps out 563bhp and 479lb ft from its 6.2-litre V8, the SLS E-Cell has four synchronous electric motors, powering all four wheels for a combined output of 392kW (equivalent to 526bhp) and a mammoth 649lb ft of torque. Crucially, all of that power is accessible from zero revs, allowing the E-Cell to sprint to 62mph in four seconds dead.

Concept Car of the Week: Matra Laser (1971)

Founded in 1937, French company Matra began its activities by manufacturing military equipment such as aeronautics and weaponry.

The first model solely developed by Matra was the bonkers, but brilliant, 1967 M530, which took its name from the company's surface-to-air missile the R530.
